Frequently Asked Questions

Question 1

Why does one Android phone have two cards? Can both control it?

Accepted Answer

USB and LAN connections retain separate cards, and both support control with consistent screen power state. Closing one focus window leaves the other open. Competing input from another window cannot interrupt an ongoing gesture. Group-control and batch targets are deduplicated when their serial number or cloud-device identifier matches. Names and model labels alone are never used to merge targets.

Question 2

Do I need to install an app on the phone?

Accepted Answer

No. Connecting to an Android device opens a temporary casting and control channel; nothing is left installed on the phone after you disconnect. iPhone and iPad use Apple's built-in Screen Mirroring, so no app is needed there either.

Question 3

Which devices are supported?

Accepted Answer

Android physical phones, Android cloud phones, and iPhone / iPad. Android 7 is the minimum Android version. Older clients may fail on Android 7 because their device service is incompatible; reconnect using a client that includes the compatible service. If connection still fails, check the connection address, port and authorization, then export logs for diagnosis. An OS upgrade is not the first troubleshooting step.
iPhone and iPad connect over Screen Mirroring with no app installed on the phone. What you can do depends on your computer's OS:
Computer OS | Mirror the iPhone screen | Control the iPhone
macOS | Yes | Yes · requires a one-time Bluetooth pairing
Windows | Yes | Not yet supported
Linux | Yes | Not yet supported
One wireless receiver name dynamically accepts independent video sessions; USB mirroring is also per-device. See the iPhone multi-device section below for capacity and device-acceptance boundaries.

Question 4

What format should I enter?

Accepted Answer

Use IP:5555, for example 192.168.1.100:5555. If you enter only 192.168.1.100, VMOS Cast uses port 5555. Multiple devices can be separated by new lines, spaces, or commas.

Question 5

Can VMOS Cast scan devices on the same LAN?

Accepted Answer

Yes. Click Add Device, pick Local network under the Android tab (the dialog opens on USB connection), then use Network discovery at the bottom of the dialog: enter a subnet and click Scan (you can also click it without a subnet to just listen for device broadcasts), tick the devices you want, and click Add. Devices already on the wall are marked as added and are not listed again.

Question 6

What does "Pairing required" mean in the scan results?

Accepted Answer

That device has wireless debugging enabled with a pairing code, so adding it directly will not work. Click the entry to open the pairing dialog and enter the six-digit code shown under "Pair device with pairing code" on the phone. Tick and add the device once pairing succeeds.

Question 7

Scanning finds nothing, or no pairing address is discovered

Accepted Answer

Discovery relies on broadcasts within the same subnet. Different subnets, guest networks, and client isolation all block it. Enter the address manually instead:
Adding a device: type IP:5555 in the input field
Wireless debugging: type the IP address and port shown in the phone's pairing dialog

Question 8

Pairing failed — what do these messages mean?

Accepted Answer

Message | What to do
Wrong pairing code | Close and reopen the pairing dialog on the phone to get a new code, then retry with it
Cannot reach the pairing port | The pairing dialog on the phone was closed. Reopen it and try again
Pairing succeeded, but the device did not connect within 60 seconds | Make sure Wireless debugging is still on and the phone is on the same network as the computer

Question 9

Why does a physical phone need USB before IP connection works?

Accepted Answer

Physical phones do not allow wireless connections by default. Connect over USB first, then right-click the device card and choose Add LAN connection — after that the cable can be unplugged. This LAN connection is turned off when the phone reboots, so it has to be enabled again over the cable (a device paired through wireless debugging is unaffected — see the next question). See LAN connection: first-time Wi-Fi setup.

Question 10

Can I connect a physical phone without a cable?

Accepted Answer

On Android 11 and above, use Wireless debugging: click Add Device, choose Wireless debugging, then on the phone open Settings → Developer options → Wireless debugging → Pair device with pairing code, and enter that code in the dialog. Pair once and the phone reconnects automatically after a reboot.

Question 11

Cloud phone cannot connect?

Accepted Answer

Check three things first: the IP is correct, the computer can reach that network, and the cloud-phone platform has port 5555 open. On corporate networks, also check VLAN boundaries, guest network isolation, and firewall rules.

Question 12

USB is plugged in, but nothing happens?

Accepted Answer

Look at the device wall first — it already narrows this down by half:
An orange "Device not authorized" card → the computer already sees the phone; all that is left is tapping "Allow" on it.
The wall stays empty → the computer has not detected it. Usually a switch in Developer options is still off (each vendor adds its own beyond "USB debugging"), or it is the cable, the port or a missing driver.
What to do in each case: Troubleshooting a connection. For the per-brand switches, see Enabling USB debugging (by brand).

Question 13

Will devices reconnect automatically?

Accepted Answer

Yes. Addresses added manually or through scanning are saved and retried on the next launch. If you remove selected devices or delete an address from Saved devices, it will not auto-reconnect again.

Question 14

Can I select and group Apple cards? Why do they remain when not casting?

Accepted Answer

Apple cards show a live preview while casting and return to the "Not casting" placeholder when casting stops. Both the sidebar and card show the reported model on the first line (iOS if unavailable) and the device name on the second. A custom client alias replaces the second line without changing the name on the phone. The Screen Mirroring device identifier remains in device details; it is not a hardware serial number. Previews reuse the video stream already received on the computer, without starting another cast on the phone, and continue while casting even after the focus window closes.
Yes. Select the name area below the card or its sidebar row, then choose "Move to group", or use the card's context menu. The wall, sidebar and counts use the same records. A record remains marked "Not casting" to preserve its alias and group; this is not proof that the device is online. Clicking its inactive casting area shows connection guidance. Remove unwanted records; starting a new cast can add them again. Apple cards do not offer Android's LAN setup, reboot or shutdown commands, and management support does not enable Android group control.

Question 15

How do I select a device?

Accepted Answer

Click the bottom or edge area of a device card. A selected card gets a blue border. Clicking the screen area opens the single-device focus window instead.

Question 16

Which devices does Select all choose?

Accepted Answer

Only currently visible devices. Search or switch to a group first, then click Select all to apply batch operations only to that set.

Question 17

What can the Status filter filter by?

Accepted Answer

Status in the toolbar is a multi-select dropdown with six entries, each showing a live device count: Online · Connecting · Screen off · Not castable · Failed · Offline.
Statuses are combined with OR, and combined with the search box and the group in the sidebar using AND
Counts reflect the set left after the current search and group filter
The filter is not saved — every launch starts with all statuses shown

Question 18

What is the small monitor icon in the top-left corner of a card?

Accepted Answer

It means a focus window is already open for that device. Clicking the card's picture again does not open a second window — it brings the existing one to the front.

Question 19

A card says "Screen is off" and the picture is black

Accepted Answer

The device screen is off; this is not a casting fault. Open the focus window and click Wake screen, or press the device's power button — the picture returns as soon as the screen is on. The button is not placed on wall cards; wake devices from the focus window.

Question 20

What is the difference between "Device offline" and "Failed"?

Accepted Answer

Device offline — the device itself is gone: powered off, unplugged, or off the network. The card is kept and the device is picked up again as soon as it returns
Failed — the device is still online, this particular connection just has not come up. VMOS Cast keeps retrying and it usually recovers within half a minute
A quick check: if the phone responds normally in your hand but shows as offline, look at the network or the address. If it shows Failed, let it recover.

Question 21

How long should a card stay on "Connecting"?

Accepted Answer

A few seconds is normal, and with many devices the first pictures appear one after another. If a card stays on Connecting for more than about half a minute, VMOS Cast rebuilds that connection automatically; if there is still no picture, treat it as Failed.

Question 22

Does switching groups disconnect other devices?

Accepted Answer

No. Groups only filter the view. Other devices keep their connections and reappear when you return to All Devices.

Question 23

Can I give a device a name I recognise?

Accepted Answer

Yes. Right-click the card → Rename and enter an alias; leave it empty to restore the default name (brand + model). The alias is stored on this computer only — it does not change the device's own name and is not shared with other computers.

Question 24

How do I tell which connection a device is using?

Accepted Answer

Right-click the card → Device details. The Connection row reads USB, LAN, or Wireless debugging.
A device connected over USB can be turned wireless with Add LAN connection in the same menu, after which the cable can be unplugged. All three behave the same on the device wall — they differ only in how the device is attached and in what happens after it reboots.

Question 25

How do I remove devices I no longer need?

Accepted Answer

Select devices, expand Batch, then click Remove selected. If the device was saved as a manually added address, that saved address is removed too.

Question 26

Can I restart or power off a device remotely? Can I power it back on?

Accepted Answer

Right-click a device card for Restart and Power off. Both ask for confirmation and are disabled for offline devices.
Restart — casting stops and the connection is restored automatically once the device is up, usually within a minute
Power off — the device cannot be switched on remotely. Someone has to press its power button. Use with care on deployed devices

Question 27

What can I do in the focus window?

Accepted Answer

Click, drag, scroll with the mouse wheel, right-click Back, middle-click Home, type with the keyboard, adjust volume, turn the screen off or on, rotate, take screenshots, and open a terminal to run commands. If the device screen is off, right-click or middle-click wakes it without also triggering Back or Home. Esc closes the window without dropping the connection on the wall.

Question 28

Can I type directly with the computer keyboard?

Accepted Answer

Yes. Tap the target input field on the phone first so it has the cursor, then type on the computer keyboard — IME input works. During Pinyin composition, the active spelling stays visible at the bottom of the mirrored screen and disappears after a candidate is committed. Cmd / Ctrl + V pastes the computer's clipboard onto the device.

Question 29

Why do some pages show no picture?

Accepted Answer

Those pages turn on screen-capture protection — common on password, payment, and DRM-protected video screens. Android blocks capture there and the card reads "Restricted by system security". This is not a VMOS Cast failure.
Some devices can keep casting on these pages: the picture still shows and stays clickable, so you can even type the lock-screen PIN in the window. Normal casting resumes when the page is left. Whether the picture appears depends on the device's Android version.

Question 30

The picture is still there on a password page, but it says the frame rate was reduced and offers "Restore live view"

Accepted Answer

That is the case described above. On a protected page the system limits capture, so the picture is delivered at a lower frame rate; it stays fully viewable and clickable. It switches back automatically when the device leaves the page, and Restore live view switches back immediately.

Question 31

Two phones on the same password page — why does only one still show a picture?

Accepted Answer

Whether a page with screen-capture protection can still be shown is decided by the device's own system, not by anything configured differently on the two phones.
Supported devices — the picture stays visible and clickable, so a lock-screen PIN can be typed in the window, and casting returns to normal once the page is left
Unsupported devices — the system blocks the picture completely, the card reads "Restricted by system security", and the page can only be operated on the phone
Seeing both behaviours across one batch of devices is normal and needs no investigation.

Question 32

The window says "Connection timed out" — will it recover by itself?

Accepted Answer

No. Connection timed out is a final state reached after repeated reconnects produced no picture, and retrying has stopped so the device is not tied up indefinitely. Close the focus window and open it again to retry; restart the device if there is still no picture.

Question 33

The window says "Video is off" — is something broken?

Accepted Answer

No. The video channel has been disabled in the settings, leaving only audio and control. Enable Video under Settings → Streaming Settings → Channels, then reopen the focus window.

Question 34

Unfolding a foldable or rotating the screen flashes "Resizing screen"

Accepted Answer

That is expected. When the device resolution changes, the window is re-fitted to the new aspect ratio, and a placeholder is shown during the transition so the picture is never stretched. It takes a second or two.

Question 35

What is the difference between Standard, Minimal, and Immersive?

Accepted Answer

Style | What is shown
Standard | Title bar + side toolbar + bottom navigation keys
Minimal | The device picture plus a narrow title bar
Immersive | Picture only; the title bar appears when the pointer moves to the top of the window
Switch under Settings → Cast window → Focus window; it takes effect the next time you open a device. The toggle in the title bar changes the current window only and does not change the default.

Question 36

What is the Terminal button on the right for?

Accepted Answer

It opens a command line for that device inside the focus window, for advanced troubleshooting such as inspecting system properties, processes, and logs. The window widens automatically so the picture is not covered. Select text and press Cmd+C (Ctrl+Shift+C on Windows and Linux) to copy to the computer clipboard; Ctrl+C still interrupts the running command. Android devices only.

Question 37

Can several computers control the same device at once?

Accepted Answer

Yes, with no limit on the number. Each computer has its own windows and input session and can operate the device directly — there is no control token to wait for — and closing one computer's session does not affect the others.

Question 38

How do I operate several devices at the same time?

Accepted Answer

Use Group Control:
Select 2 or more devices that are already showing a picture on the wall
Click Group Control in the toolbar
The first device opens as the master, with "Master · N" shown at the top
Every tap, swipe, and drag in the master window is mirrored to the other selected devices
Group Control syncs screen gestures only. Keyboard input goes to the master device only. To run the same action across a set of devices (install, uninstall, command, screenshot), use batch operations.

Question 39

It says group control needs at least 2 streaming devices selected

Accepted Answer

At least two of the selected devices must already be showing a picture. Selecting a single device, or devices that are still connecting, offline, or not castable, does not qualify. Wait for the pictures to appear and click Group Control again.

Question 40

What is Multi-view, and why are some devices missing from it?

Accepted Answer

Multi-view shows all devices of one group in a single window, and every tile can be operated directly with the mouse. Open it from the monitor icon next to a group in the sidebar, or from the Multi-view dropdown in the toolbar.
A multi-view holds up to 16 devices. Anything beyond that is not shown and a notice reports how many were left out. Split the group if it is larger
Members are a snapshot taken when the window opens: adding or removing devices in the group afterwards does not change an open window. Close and reopen it to refresh
Auto arrange prioritises keeping every device fully visible, scaling panes down and leaving space when needed. Slight contact does not swap panes. A target swaps into the drag-start position only when more than half covered and both panes fit, without overlap or pushing other panes downward
To move the whole window, drag its title or the empty area of the top title bar. To deselect a pane, click empty workspace or switch windows
Quick replies are available only in the Android single-device window toolbar, not in Multi-view.

Question 41

Why is there no Wake screen button on a multi-view tile?

Accepted Answer

Tiles are reduced-size views that show status but carry no action buttons. Use the expand button on the tile's title bar to open that device's own focus window, and click Wake screen there.

Question 42

Where are batch operations?

Accepted Answer

Select devices first, then click Batch in the top toolbar.

Question 43

Which file formats does batch install accept?

Accepted Answer

Installation accepts apk / apks / apkm / xapk, and several files can be selected at once. Push File accepts any format.

Question 44

Why does batch APK install fail on some phones?

Accepted Answer

Common causes include phone-side install confirmation, mismatched old app signature, low storage, expired USB debugging authorization, or unstable network. Test on one or two devices before running it on a whole group.

Question 45

Where do I find the package name that batch uninstall asks for?

Accepted Answer

Package names look like com.example.app. The quickest way to get one is Run Command in the batch panel: pick "List 3rd-party" from the command presets and find the app in the output.

Question 46

Is batch uninstall safe?

Accepted Answer

Batch uninstall cannot be undone. Confirm the package name, test on a small set, then run it on the group.

Question 47

Run Command says offline devices were excluded, or that all selected devices are offline

Accepted Answer

Commands run on online devices only. The first message means some of the selected devices were skipped while the rest ran normally; the second means none of the selected devices were online, so nothing ran. Refresh the device states or change the selection, then run it again.

Question 48

How do I export the IP addresses and models of a set of devices?

Accepted Answer

Select the devices → Batch → Copy Info. Tick the fields you need (device ID, IP address, name, resolution, Android version), choose a separator (comma, new line, pipe, or space), check the preview, and copy to the clipboard — ready to paste into a spreadsheet.

Question 49

Where do pushed files land on the phone?

Accepted Answer

In /sdcard/Download. When the push finishes, each device reports where its file was stored, and failures are explained device by device.

Question 50

Where are batch screenshots saved?

Accepted Answer

They are saved to the folder set in Settings → Streaming Settings → Screenshot location. Batch screenshots and focus-window screenshots both go there, and saving no longer prompts you for a location. If you have not changed it, the default is VMOS Cast inside your computer's Pictures folder. After a batch you get "Saved N/M screenshots" together with the full folder path, and Settings has an Open folder button.
File names automatically include the device name and timestamp (e.g. Pixel 7 Pro-20260827-161105.jpg), so they never overwrite each other. Capturing many devices repeatedly uses resources and disk space, so wait for one round to finish before starting the next.

Question 51

Batch screenshot reports a save failure

Accepted Answer

That is a problem on the computer side, not on the device: the screenshot folder was deleted, moved to an external disk, or is not writable. Pick a writable folder under Settings → Streaming Settings → Screenshot location and try again.
Individual devices report their own reason instead. The two common ones are a screen that is off, and a page with screen-capture protection enabled.

Question 52

How do preview quality and resource use change with several iPhone displays on Windows?

Accepted Answer

USB and wireless mirroring both share video decoding per video source. Wall previews have a maximum long edge of 640 pixels; independent displays preserve the original source while rendering at the window's physical display size, redrawing when enlarged. This requires no second cast and does not change phone control coordinates. Closing a display releases that window's video resources and keeps its wall preview; ending that video session releases its video resources. Other sources keep independent pictures and control. USB and wireless sources from the same phone are not automatically merged and do not share decoding across those connections. Android quality, frame-rate and bitrate settings do not change this iPhone video path.
Evaluate capacity with moving pictures, the number of open displays and control response, rather than a static page or a single memory reading. Keep the displays you need to operate open; opening Control method does not add another video decoder. If memory keeps accumulating after repeatedly opening and closing the same displays, or closing one phone stops another picture, export logs with the phone count, video dimensions, whether remote desktop was in use and the time of the problem.

Question 53

The phone responds smoothly, but the computer picture lags or stutters

Accepted Answer

Compare the phone, focus window and thumbnail. If the phone has responded but the computer picture has not updated, investigate video reception, decoding or window relaying rather than simply increasing pointer speed. Export the client logs and note whether only the focus window is slow and whether remote desktop is in use. The iPhone display prioritizes source resolution, but network conditions and computer load still affect smoothness; Android display quality and bitrate settings do not control iPhone.
iPhone / iPad support independent mirroring and management, without multi-view, Android group control or batch commands. Viewing does not require Bluetooth. On Windows and macOS, choose Enable control in the independent display and follow the illustrated pairing guide; Linux is view-only. Losing Bluetooth leaves mirroring running. Closing the display preserves wall thumbnails. Inactive records can still be selected, renamed, moved or removed. Configure Auto-Lock on the phone.

Question 54

How do I connect an iPhone or iPad?

Accepted Answer

Nothing to add in the Add Device dialog · mirroring starts from the iPhone. Put the iPhone and computer on the same reachable local network, swipe down from the top-right corner to open Control Center, tap Screen Mirroring, and pick this computer. It then appears on the device wall automatically.

Question 55

An iPhone card says "Not mirroring" — how do I start?

Accepted Answer

"Not mirroring" means that iPhone has connected before and is not mirroring right now; it is not a disconnection. On the iPhone, open Control Center → Screen Mirroring and select this computer again.

Question 56

This computer does not appear in the iPhone's Screen Mirroring list

Accepted Answer

Check in order:
The iPhone and computer are on the same reachable local network, not a guest network or one with client isolation; the computer may use Ethernet
The receiver status on the iPhone / iPad tab of Add Device. Click Retry if it reads "Receiver unavailable"
Multicast and broadcast restrictions on corporate networks stop the iPhone from finding the computer — verify on an ordinary Wi-Fi network

Question 57

Can two iPhones mirror at the same time?

Accepted Answer

On every iPhone or iPad, choose the same receiver name shown on the Add Device page in Screen Mirroring. Each incoming phone gets its own video session and device card, without pre-created numbered entries or a fixed two/eight-entry pool. Open separate displays for the phones; one sender stopping or disconnecting does not interrupt the others. Usable capacity depends on computer decoding resources, memory and LAN bandwidth, not an unlimited-device guarantee. Names are not unique identities. An unidentified connection belongs only to its current session, and an old connection cannot receive another phone’s picture. USB mirroring remains per-device.
Multiple-device Wi-Fi / USB control: Phones with compatible input services can use independent Wi-Fi or USB control in their own displays; there is no client-wide one-phone lock. Prepare and trust each phone separately. For wireless video, explicitly confirm the input target on first selection even if there is only one candidate; names and connection order cannot establish identity. Stopping one display’s control leaves other phones unaffected. If the same phone appears in both USB and wireless displays, only one window may own its developer input channel at a time to prevent duplicate input; stop that window’s control before switching. Wi-Fi capacity does not establish Bluetooth capacity.
Bluetooth control (Windows / macOS): Each computer controls one iPhone over Bluetooth at a time. Select and confirm the target in its display; ot

Question 58

Can I control an iPhone from Windows or Mac?

Accepted Answer

Yes, with compatible Bluetooth and the Enable control guide in an independent display. Complete pairing and Zoom setup. Linux does not support iOS control.

Question 59

The picture is visible or pairing succeeded, but taps do nothing

Accepted Answer

Mirroring and control are independent. Confirm the picture is live and Bluetooth connected, enable Settings › Accessibility › Zoom at normal picture size, then verify a tap using the guide. Connected status alone does not verify control. The retired AssistiveTouch pointer mode is not a prerequisite.
If the Bluetooth control service exits unexpectedly, the client shows Retry. Restart the service before checking the phone's Bluetooth list. If the computer is not listed, there is no pairing record to forget.

Question 60

Does control lock my mouse in the phone picture?

Accepted Answer

Direct touch does not lock the computer pointer. Click the displayed target or hold the left button to drag; leaving the window releases contacts and keys. If taps are misplaced, check magnification and whether the picture has frozen. See iPhone control.

Question 61

Which toolbar actions are available in an iPhone display?

Accepted Answer

The control entry in the right-hand toolbar shows the active method (Bluetooth, USB or Wi-Fi) and reconnects the last method after a disconnect; Screenshot and Copy current picture remain available. Once USB / Wi-Fi LAN control is connected, Home, App Switcher and an optional Touch trail also appear. Bluetooth cannot perform those three actions, so they are hidden automatically. Android volume, Back and bottom navigation keys remain hidden.

Question 62

I changed the frame rate, bitrate, or channels — why did nothing happen?

Accepted Answer

Focus-window settings do not apply to windows that are already open; close the window and open it again.
Setting | Takes effect
Thumbnail size | Immediately
Main window size, theme, language | Immediately
Full Screen FPS, Full Screen Bitrate, Channels, Focus initial size, Focus window style | Next time you open a device
Device List FPS | Next time a device connects or reconnects

Question 63

What do the three Channels switches do?

Accepted Answer

They decide which channels are opened when a device is opened in a focus window:
Video — the picture. With it off, only audio and control remain and the window reads "Video is off"
Audio — device sound played through the computer
Control — mouse and keyboard input. With it off the session is view-only and the picture is unaffected
All three take effect the next time you open a device, and apply to Android devices only.

Question 64

Many devices and everything is slow — which setting should I change?

Accepted Answer

For Windows USB and wireless mirroring, a frame-transfer failure triggers one rebind attempt for that preview or display only, without restarting other sources. A successful frame restores its retry allowance; repeated failures produce an explicit error rather than endless retries or a silently frozen picture. If Screen Mirroring was stopped on the phone or the network connection actually ended, select the receiver again on the phone. Switching to Bluetooth control does not restart video.
The following FPS, bitrate, quality and Pause list picture while full screen is open adjustments apply to Android only. They do not control the iPhone video path; see Windows iPhone preview quality and resource use. For Android, work out which layer is slow; the two sets of parameters are independent.
The device wall is slow — lower Device List FPS and reduce the thumbnail size, and use groups to hide devices you are not watching
A focus window is slow — lower Full Screen Bitrate first (8 → 4 → 2 Mbps), then drop Full Screen FPS to 30 or 15
If two picture streams from the same device compete on a constrained network, enable Pause list picture while full screen is open under Settings → Streaming Settings. The wall thumbnail then pauses while the device is in a focus or multi-view window and resumes when it closes. This setting is off by default.
To keep devices awake while you watch them, light the bulb button in the focus or multi-view title bar. It applies only to the current window and doe
