The Ender Ender

I was just playing Minecraft Bedrock one day because I was bored and started a new world, on the beta, in survival. Here is a log of the stuff that happened.
DAY 1-
Basic first Minecraft day. Gather wood, settle in cave, kill sheep, pigs, and cows, sun set, all is good...
DAY 2-
I started exploring, and I kept seeing 16x16x16 areas of blocks missing and some 16x16x16 areas of blocks out of place near them. I tried to decide whether it is a chunk error or something else... Eh. It's the beta. Things happen. Anyways, I get iron, and return to my cave home.
DAY 3-
The "chunk errors" start to multiply. Some even appear in places where they were not there before. This is very suspicious.
At night, I attempt to sleep. "You may not rest now, there are monsters nearby." I head outside with my iron sword and see a very tall black figure in the distance, 16x taller than an enderman, holding a large thing of blocks. Before I can take a screenshot, the thing of blocks is placed on me, and I suffocate. Due to there being shaders on and me having a trash tablet, my game crashed. When trying to load Minecraft back up, it crashes again, and again, and again. I had no choice to reinstall the game. (I had my file storage on application, because if I put it on external, it would glitch out, I think due to a malicious "MCBE Optifine.")
