[brukdibuddy]

aight heres the problem i dont know what happen to my fone but today as soon as i pic up the fone like jus lift it the screen will turn on and normally that wouldnt happen also i notice that if you flick your finger across the screen when it is off the fone wakes up . now im wonderin am i the only one that got this problem ? is this normal? then on top of that there is the issue of the keyboard working and then stop working . shold i go to the sprint store and take da risk of getin a refurbish fone or the tech just messin my fone even more or is there like a cab or something to fix it. thanks to those who reply
