From an iPhone 6 user – Pokémon GO Review

I uninstalled the game once because I was too upset with game crashing. So does my boyfriend. He couldn't install it back because his Android phone bought last year is really too slow for the game. And the GPS location in this game is less and less stable, never enough for me to join a Raid fighting anymore. I thought it's my phone's problem. BUT, that doesn't happen on my map apps, which I can't really understand.
