Resoution on mobile?

The game packaged to my android pad has a low resolution,when i see the GameUserSettings.ini file on mobile,it shows that ResolutionSizeX=960,ReesolutionSizeY=720,however,my device’s resolution is 15362048 actually.How can i change the game resolution on mobile?
I have also tested the same game on my mobile phone which is 1920
1080,the game can only run with 1280*720,is it a bug?Or if not, how can i chage it to fit the device resolution.Thanks!

Try this:

  1. In editor; Go to Window > Device Profile Editor.
  2. Find Android in the list and click the little spanner/wrench/settings icon (a new window should pop up)
  3. Under Console variables, expand the ‘Rendering’ section (if not already expanded)
  4. If there is no variable called r.mobilecontentscalefactor then click the plus button (’+’) and type it in, clicking on it when you see it
  5. Change the ‘r.MobileContentScaleFactor’ to double whatever is already in the box (if 0.5 then change to 1, if 1 then change to 2. Don’t go higher than 2)

Let me know how you go!
