Devices are starting to come out with crazy high resolutions, like 2560x1600 on my Note 10.1 2014. Even tho this is a new device, many games lag on it. I found an app after much searching that does change the resolution but is very buggy (crashes on my tablet when resetting resolution) and lacks many features. https://play.google.com/store/apps/details?id=com.nomone.resolution_changer If someone could run with this idea, but make it more stable.. add profiles you can save.. add per app/game settings so it automatically switches to the desired profile when running that app (and resetting default when closing). That would be awesome.. Thanks for reading.
