Ever since the 1.2 update, when I try to leave the game, the window with 2 blank boxes appears and I can't press any one of them. So the only way to quit is by pressing the Android key listing all active apps and then manually press "x" on Minecraft tab. The same issue is when I tried to set some settings to my Xbox Live account than pressed "back" and Minecraft showed another popup window informing it won't save changes. Again, there were 2 blank unclickable boxes.

Before the 1.2 update my game was running very well. Please fix this

My phone is LG K8 LTE 2016 edition
