Frequently Asked Questions


What is VMOS?

VMOS is an APP software based on Virtual Machine (VM).
VMOS can be installed in the form of a normal APP to Linux or Android system through VM technology.
That is to run another complete Android system through an application.
Moreover, VMOS is not controlled by the host system. (Android on the phone).

Why does VMOS ask so many permissions?

we are asking all these permissions for better simulation of a physical phone.
VMOS is a system can install Apps, we are asking specific permissions to make sure users can use apps that need those specific permissions. (Android 5.1 ask all permissions before you download apps)
1. Floating window permission: For better playing the virtual machine on the real machine interface.
2. Storage permissions: Because the data in the virtual machine is empty, considering that you need to transfer the local file. This permission will only be used for the file transfer station.
3. Recording permission: This permission will only be used when you use voice transmission or call.
4. Camera Permissions: This permission will only be used when you use the camera, such as scanning QR code, taking photos, and video calling.
5. Device information: Because the device information of VMOS is originally empty, you need to obtain the device information of the real machine to make the device information of the virtual machine the same. There is sensitive information in these data, but we do not upload and collect data.
6. Telephone rights: The device information such as IMEI of some mobile phones is permission.

Does VMOS run in the cloud?

VMOS is running locally, including the memory (RAM) consumed by the runtime and the storage space (ROM) consumption.

What is the difference between VMOS and cloud phones?

The biggest difference between VMOS and cloud mobile phones lies in resource consumption.
All the performance parameters of cloud mobile phones are derived from the merchants, you can only change the internet speed.
However, VMOS is completely dependent on the performance of the real machine.

What are the requirements of VMOS?

Because VMOS is a virtual system, the size of the system is difficult to reduce.
So at least 3gb (RAM) + 4gb (ROM) free space is required to enter VMOS, and 3gb ram + 32gb ROM or higher mobile phones are recommended.

What data does VMOS collect?

For better user experiences, we collect your phone model and the error log.

Why I can't see the floating ball?

The floating ball needs to be granted permission by the real system.

Why does the floating ball change color?

The color of the floating ball is for better distinguish the physical machine and the virtual machine.
Blue: In the virtual machine.
Green: The physical machine.

What is the floating window?

The floating window can change VMOS's picture into a small window, similar to the application window on the PC.
It can be freely zoomed and dragged.
You can also realize the simultaneous operation of the physical machine and the virtual one.

How to zoom in and out of the floating window?

When the pushpin in the upper left corner of the floating window is white, zoom in and out by two fingers.
Click the pushpin to lock/unlock the window.

How to make the floating window horizontal?

When the pushpin is white, there is a spin button in the lower right corner of the floating window.

How to mute VMOS in the floating window?

When the pushpin is white, there is a mute button on the lower-left corner of the floating window.

How to turn off the floating window?

There is a minimize button in the upper right corner of the floating window, click it to zoom out.

How to activate Xposed?

Restart VMOS after Xposed installed.

Why I can't install Magisk?

VMOS and Magisk need to be adapted. It takes time.

How to run the apps in the background?

After running the application, click "Return" in the floating ball, or press HOME in the physical machine.

Why do apps running in background drop, kill, black screen, or reboot, etc.?

1. The phone's memory is exhausted and is killed by the system.
For example, if a game's running in the virtual machine, which is also running in the physical one, one of them will be killed when the storage is insufficient.
2. The battery optimization's been added, the system automatically detects high power consumption.
Then the system kills the process by default.
It would be solved by adding a whitelist to the battery optimization of the real machine settings.

Why some apps or games aren't running?

Compatibility issues exist in some apps or games, our dev team would fix it case by case.

Why does the phone stuck and became very hot?

The configuration of the physical device is not good enough.
Or you are running a game.

Why can't I use the SIM card to make a call?

This function is currently under development.

Why can't I connect WIFI? Where are the buttons on the navigation bar after the version 1.0.31?

As VMOS is always sharing the network environment with the physical system,
the buttons inside VMOS with the same function are useless.
So we've temporarily removed them, which will be back after they could work separately.
If the VMOS on your device is unable to connect the internet,
please uninstall VMOS and download it again.

Why can't I connect Bluetooth?

Since we haven't solved the technical difficulties on the function yet,
Regarding our apology, it's not possible to use Bluetooth in VMOS currently.
However, we've already got several feedbacks, and are trying to figure out a way to manage that.
Please keep an eye on our updates.

Why can't I use NFC?

It's under development.

Can I import local files and applications into VMOS?

Sure, we have a built-in app in VMOS called file transfer station in yellow.

Helio p60(Realme 1) issues

VMOS has purchased the same phone type abroad to fix this problem.
Please keep an eye on the VMOS update.

Can't play games

A. Game detects VMOS
B. The game needs some physical hardware sensors or information that the virtual machine couldn't get from the physical system.
C. The Android version is too low. Can not run the game
D. The configuration of the device is not good enough.

Can't connect wifi/mobile data/internet inside of VMOS

1. the internet connection of VMOS depends on the physical device.
If the physical device connected with wifi, so does VMOS.
If the physical device connected with data, VMOS would be connected as well.
2. Keep the [wifi] button inside of VMOS on.
3. the [wifi] button of VMOS and the [Data] button of VMOS is just a switch, but can't choose which wifi to use.

Can't connect VPN in VMOS

Please connect VPN in your physical system.
The VM system shares the same internet environment with the physical system.


Adjust your settings depends on your device.
frame rate→high
Automatic graphics→disabled


We have recorded this issue.
Developers are working on it.

About location permission

VMOS itself doesn't need your location.
Location permission is for Apps (like Ar-game, etc.) in VMOS that might need it

Will the android version of VMOS be higher? 

It's already on our plan list.
We will upgrade Android 5.1 to higher version soon.
Keep an eye on our updates.

How many storage/spaces does VMOS need? Insufficient storage.

The entire app is around 300 MB.
Considering apps will be installed in VMOS, we recommend at least 4 GB free spaces in the device.
However, sometimes the insufficient storage would still pop up even if there are 4 GB empty spaces.
In this case, please try to spare more for VMOS.

Can't find root / no root

Now you can see that the root option is on the first setting page, no longer need to switch it on/off in the developer options.

Can't open VMOS

We recommend running VMOS on a phone with more than 3GB RAM and 32 GB Storage.

CPU is also related. 

Screen Rotation

Click VMOS ball→Notifications→Auto-rotate.

VMOS is extremely slow when turning on

VMOS is not a simple app, it's a virtual system

The screen freezes after I entered PUBG Mobile (global). 

Don't install too many apps in VMOS. Please shut down all other apps before using VMOS and run PUBG again.
We will optimize the system as much as we can.

The brightness adjustment doesn't work, neither go up nor go down

Currently, it's not possible to change the brightness in VMOS.
It's synchronized with the physical system.
We apologize for the inconvenience.
We'll figure out a solution to add a hint in the virtual system.

Flash Player

VMOS can't adapt to Flash Player currently.

Android 4 system

VMOS can't adapt to the Android 4 system currently.

How to uninstall Google App in VMOS?

Download MT file manager→Delete related file folders.

Why not all applications I own appear in the browser file transfer station?

The system app won't be shown. The running of the system app relies on the physical system.

Why does power consumption go so fast when running VMOS?

We have noticed this problem.
We will optimize it as much as we can.

Some wifi-related Apps can't detect the wifi, such as wifi kill, WPS app

Currently, the wifi penetration inside VMOS is uncompleted.
Some wifi-related Apps can't be supported.
We will try our best to fix it as soon as possible.

Why I can't download some apps/games from Google Play inside VMOS, such as Clash of Clans?

This is because of the rules of Google Play.
Google filters device by type and checks the compatibility of apps with the emulator.
We will keep trying our best to make VMOS compatible with more apps.

How to remove the root access in VMOS?

Currently, VMOS has a function to turn on/off the root access.
Since completely remove root access needs to delete some relevant files, which including technical difficulties, this function is still under development.
Please kindly spare with us and keep an eye on our updates.

How to record phone calls in VMOS?

We are now developing this function.
Please check our updates.
