When I go into the settings-minecraft crashes

My phone is from the middle segment, while it used to be rare. To the problem: when I want to enter the settings, 1 out of 2 attempts crashes the game. More often occurs if you are near a numerous spawn mobs or ashore (OPTIMIZATION). Mali 7200 processor, 1GB RAM (More often it uses 213 not 400 summary memory). Please clear the game for ALL segments! After all, I'm not the only one with a weak phone ... MOJANG I BELIEVE IN YOU!
