Unexpected crashes

Unexpected crash happens on the RED Hydrogen one (official open version ROM) running on android 8.1 

it can occurs in many conditions, such as generating maps, exploring world rapidly, or just standing there and do nothing .

i don't know if it's due to the RED company Who had very bad system maintenance (hasn't release any update for more than a year because their company thought  this smartphone was a failure work) or just a series of bugs about Minecraft
