pokemon go isnt working on my phone

[AC Question]

I have the LG Sunrise l15g I can open the app and it get the screen where it says "NIANTIC" and "the pokémon company". It stays on that screen for about 15 to 20 seconds then the app closes, I tried turning my phone off and on again to see if that would do anything but it didn't help. I then saw there was an update so I updated it and that didn't help so I tried uninstalling and reinstalling it and it still doesn't want to work. I can never get past that first screen
