Howdy Evgeny,

Thank you for reporting this resolution error that you have been seeing. I have tested on a device internally that is closely related to your device but I have seen no errors. I have checked our Android Device Compatibility sheet and, since your device is not listed on that sheet, that your device is not supported.

This does not mean that you device is unable to run any project deployed to it, but, since it is untested, we are unable to provide any solution as to what may be occurring. I was using the Xiaomi MI-2S mobile device and saw no errors. Have you changed any of the Android Project Setting that could of caused the error or would this be with a fresh download of ?

Thanks and have a great day!

What settings to change?
Verify please on the device with a resolution 1920*1080.
I reload - nothing has changed.
More screenshots of my project
ver 4.6

ver 4.7

Pay attention to the HUD.
Can be a problem in +CVars=r.MobileContentScaleFactor.
I change value but nothing has changed.

Thank you for your attention!

Are you using the 4.7 version of UE4 of the 4.7.1 version? I have been testing in 4.7.1.

Also would you be using a binary build of UE4 or a source build?


I`m using 4.7.1 version, and binary build!

Would you be changing any of the Android Project Settings under the Project Settings? If you have, would you be able to provide screenshots of your settings?

Can you replicate this issue on a blank template project?


With screenshot Blank project

With screenshot android settings

I`m download from google play the problem remains

I have tested , both deployed from UE4 and from the Google play store, and still have not seen any errors. I believe that the error still has to do with the device not being supported. Though you have seen it work before, it does not always mean that deploying projects to that device will work. With that device being on the lower end of CPU and GPU, That seems to be the only conclusion I can make at this time.

Would you have any other devices that you may be able to test on? Possibly one that may be on that list. That would give us the best chance to compare and see if it is the device or the project.


I solved the problem.
In GameMode blueprint, add Event Begin Play → Execute Console Command-> setres 1920x1080.

In Level blueprint I added :

Screen launched application

Resolution Not detected!
