Lately, my phone has been acting very strange. Everytime I boot my phone, the phone is blank, the screen turns on, but no Motorola M. Eventually, I can turn the screen off and on, so I guess that means it's booted. But then, I try to turn my phone on to get the lockscreen, but the only thing that happens is keyboard and back, menu, home, search button turn on, but no screen. I don't understand why this is happening. Can somebody help?
