1.6.1 - 1.7.1

I haven't played Minecraft for 1 and a half months because of this bug! And Minecraft's my #1 game I play! Whenever I open the game, it shows MINECRAFT, looks like its gonna open, but then it just crashes, I know that this bug isn't any corrupt files because this bug has happened to my game angry birds, after it was updated, it worked, Mojang please work on this bug ASAP, I really want to play Minecraft, if not I might think about getting a refund. The video will not upload, if you want to see it Mojang just email me and it might send on email.. My phone is a Samsung Galaxy Express Prime 2.
