Loading screen freeze

Dear Mojang,

I play Minecraft on the Kindle Fire edition. Recently I have been
experiencing loading issues. When I load up the game, it freezes on the
white background, MINECRAFT screen when I slide up on the tablet to see the
little menu. Even if I don't do that, the game doesn't load up as fast as
it used to. I use the Fire 7 Tablet which is running well. I tried the
best, uninstalling and reinstalling but nothing. It still freezes. Please
make an update and try to fix this for me, thanks! Edit: I recently tried this on my brother's tablet and it worked, is there something wrong with mine I tried clearing the app out but nothing so far.
