Minecraft Crash, Force Close

Minecraft Beta Keep crashing on my phone, when i play this game for 10-20 menit its starting framedrop which is mean it will force after it, and when i try to enter the game again, less than 5 minutes the same things happened, sometimes i can't open the game too, theres always a pop up saying the minecraft always stop, solve this problem please, this problem i got from the previous beta version, when this game had an update, i always update this game, i think the force close problem was gone but still the same, the update don't change anything
