Hi.
I'm on a Samsung Galaxy S6 Flat (Model: SM-G920I).

The problem is that the game crashes every time I die while been affected by wither effect.

It happen in nether against a Wither Skeleton and in overworld against The Wither.

The only way I could play was to set the game to easy so there was no Wither Effect in the game.

You don't get to see when you die. It cashes at the moment you get the final hit.
