Game won't load at all

I am playing on an Android Samsung Galaxy S6. Minecraft tries to load on my phone and gets stuck on the white Minecraft loading screen. I habe walked away from my phone long enough to eat dinner and came back to it still being on the loading screen. I have uninstalled and reinstalled Minecraft and I am still having the same issue. So basicly I can't play Minecraft at all until this issue getsL resalved.
