Here's the 2 thing in Minecraft:

1. When I reopen Minecraft, I can't tap and scroll ones, and when I tried to pick my items, I can't tap it ones

2. When I look to the tree, it got lag for no reason, I get attack by the mobs, and I can't do the MLG stuf, only look at the sky and the floor can't be affected but when I look to the mobs or the walls or anything, it got lags

This is the proof, I hope you fix all of these mess
