I'm using a Cubot GT72 and I had the previous versions of Clash of Clans and it worked, now after this update it says there is not enough storage at 99% or at 'Installing' it says 'Error 919' or something like that, how do I solve that?

-Another thing that I also found was on my Cubot GT72 when I try speak on Global Chat/Clan Chat it takes like 20 seconds for the keyboard to come out, but I'd really like it if someone tells me how to fix the first issue.
