APM?

I have APM questions, I've tried YouTube videos, and maybe it's my type of phone, but doing APM then closing the app, or clearing the cache doesn't work. I have to uninstall/reinstall. So.. What types of phones do y'all have where you don't have to uninstall/reinstall? And How long does it take you to complete a whole tournament all the way to grand prize while doing this? I imagine many hours? I tried and I had 5 bad rolls in a row and didn't have the patience to uninstall/reinstall that many times in a row, but YouTube and Tik Tok make it look so easy!
