There is a bug with Warzone Mobile. The resolution is not even 1080p(I’m not talking about the textures). Until you go to split screen mode and open another app and make the warzone window smaller and then go to graphics settings and come back out of it. The resolution returns to 1080p. If you are already in 1080p res, and if you try to go to graphics settings again. It glitches back to 720p. Please address this bug.
Glitched resolution (720p)
Correct resolution (1080p)
The workaround:
