Beta

Dear Mojang, I can't play Minecraft Beta normally, it has crashes. I can't play with servers or local players. The worst thing is that I can't enter the marketplace. While I enter it, the games stops. Also Endermen are spawning a lot in the Nether and there are a lot of lava everywhere. Sometimes, when I go somewhere while playing, I turn on my phone, and I see that there is nothing except white screen. Please fix it all.
