hello, ive had my razr for like 5 months now, and i just recently started using it like almost every minute for texting.. and like now some of the keys dont work like the #7,#6 and the backspace.. also the space button.. i have not been around any water.. and i took the battery out and there was no red spot on the back indicating water damage.. also now, when i open my phone.. it automaticly hits the #7 key and hist send on its own! so its a speed dial and it calls my ex.. lol.. so what do i do? and i think i still have my warranty..
