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).

VMOS PRO Basic Operation Tutorial:

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 depended on the performance of the real machine.

What are the requirements for VMOS operation?

Because VMOS is a virtual system, the size of the system is difficult to reduce.
   So at least 2gb (RAM) + 2gb (ROM) free space is required to enter VMOS, and 3gb ram + 32gb rom or higher mobile phones are recommended.

Why does VMOS ask so many permissions?

   We are asking all these permissions for better simulation of a real 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.

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 to better distinguish whether it is in the real machine or in the virtual machine.
Blue: In the virtual machine.
Green: The real machine.

What is the floating window?

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

How to zoom in and out of the floating window?

When the pushpin in the upper left corner of the floating window is white, use two fingers zoom in and out.
Click the pushpin to lock and 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 in 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 real machine.

Why does the background run App drop, kill, black screen, or reboot, etc.?

1. The phone's memory is exhausted and is killed by the system.
For example, the virtual machine opened a game, the real machine also ran the game. One of these two will be killed if 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 real phone configuration 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 developing.

Why can't I connect WIFI?

Currently, the hardware information of the WIFI is penetrated, and the list of nearby WIFIs is completed. (but we can't choose from the wifi list, it should be done in your real system)
We will keep moving on.

Why can't I connect Bluetooth?

As for Bluetooth, please connect the other device(headphone, watch, Gamepad...) in your real system.
VMOS has the same Bluetooth environment as the real system.

Why can't I use NFC?

It's under developing.

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)

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

Free Fire

The dev team is now trying to fix this issue.
Please keep an eye on our next update.

Can't play games

A. Game detects VMOS
B. The game needs some real hardware sensors, or some information, the virtual machine does not get it from the real phone.
C. The Android version is too low. Can not run the game
D. The phone configuration is too poor. Cause the game to flashback

Internet Error

①VMOS system has the same internet environment with the real system.
wifi button in VMOS is not running for the time being.
②If you still get internet error.

Can you visit

If can't, please change Wifi to data (or data to Wifi), or connect it with VPN.
(all internet setting should be done in your real phone system)

Can't connect VPN in VMOS

Please connect VPN in your real system.
The VM system has the same internet environment as the real 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

Basically, VMOS itself doesn't need your location.
Location permission is for Apps (like Pokemon Go, etc.) in VMOS that might need it

Will the android version of VMOS be android 9.0? 

It's already on our plan list.
We will upgrade Android 5.1 to Android 9.0 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 2 GB free spaces in the device.
However, sometimes the insufficient storage would still pop up even if there are 2 GB empty spaces.
In this case, please try to spare more for VMOS.

Can't find root / no root

Developer options→Grant root permission

Can't open VMOS

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

Screen Rotation

Click VMOS ball→Notifications→Auto-rotate.

VMOS is extremely slow to turn 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 soon as possible at the same time.

Will VMOS has Lite version for 2GB (or less) 

Yes, it is.

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

Currently, it's not possible to change brightness in VMOS.
It could only be the same as the real system.
We apologize for any misunderstanding this situation as caused.
We'll figure out a solution to add a hint in the virtual system.

Why does VMOS need the permission of IMEI?

We are asking IMEI for the better simulation of the real system.
Also, as VMOS is a system that would install apps inside,
IMEI is asked to make sure users could use the apps which need IMEI.

Flash Player

VMOS can't realize the adaption with Flash Player currently.

Android 4 system

VMOS can't realize the adaption with Android 4 system currently.
Custom Recovery
It's on our plan list.
Please keep an eye on the VMOS update.

How to uninstall Google App in VMOS?
