My Motorola rival (purple) is barely 3 months old and just four days ago, I was sitting in the car and pulled it out of my back pocket and the screen was black. The buttons were working perfectly fine, though. I pulled turned it off and on, then pulled the battery out and turned it back on and off. When I got home, I plugged it into the charger and it was working perfectly fine. The screen liit back up and appeared. I let it charge all night. Once I woke up, it was still working fine. Later on in the day I pulled it out and began texting. I put it down foe just a few minutes, picked it back up and the screen was black once again. This time, when I plugged it into the charger, it did work. I've taken the battery out plenty of times and nothings working. Please help asap!
