I've been team android for so long and I completely ruined it, I dropped it in the toilet twice and the should stopped working lol I stopped paying for it and just used WiFi but I shattered my screen for the first time yesterday! I'm getting glass stuck n my thumb as I type this lmao. ANYWAY it's time for a change and I need advice
