Hey there, I just figured out that Im experiencing a defective power button, whenever my phone goes standby I couldn't wake it up whereas when its power off I couldn't switch it on. The thing is this is a USA set I have no idea how does the warranty works here. I heard that I can root it so I can replace power button's function with trackball. If I don't plan to root, is there any other method? Please send me some guides, thanks a lot great day ahead!
