Phone:Zenfone Go X007D

Hello, I normally launch Minecraft and I want to join the Massive Servers but I have to connect to Xbox live so I put my identifiers in the boxes and I press the button "connect" and ... white page that loads and it restarts me Minecraft.

P_.S: I'm French and I would like you to work a little more on the mobile version because every time I have to go on the desktop version which is "uncomfortable". Rating of website: 4.5 / 5 stars
