I have to factory reset every 2 months to keep my POS RazrM running smooth. I dont know what it is but after a while the **** must pile up in its gears and cogs to make it force close apps and run like a giant slow useless turd. I cant get a new phone till February. Maybe I'll see if there's any old CDMA phones at the thrift store I can root easily or something. Maybe I'll finally root this since the cracked screen probably already voided my warranty anyway. I've never rooted anything and it always seems that the phones I get are the most impossible to root. I'm on kitkat so it looks next to impossible. :-!
