Are you sure, what you playing with disabled cheat mode?
I've seen, people here writing what you can start game, after changing date for more early, than 1 July, but this doesn't work. How game stops at logo screen before the change, it continues stops after.
Device: Xiaomi Redmi 4X
Android: 7.1.2
Affected Minecraft versions: 1.4.4 and beta 1.6.0.5
Same issue at 1.4.4 and beta 1.6.0.5, Android version 7.1.2, just stuck on logo and doesn't open main menu. (Device: Xiaomi Redmi 4X)
Looks like this issue can be fixed without 3rd party tools. In my case (world was at Bedrock Dedicated Server) it's fixed by teleporting bugged player to other player(or to himself)
