So last night, my Droid 4's display stopped working whenever I slid the keyboard out. It just goes black. I can still type and then when I slide the keyboard back and the screen comes back, it has typed letters. I don't think there was a drop or any one incident that made it stop, so I don't know what caused it. If I unlock the screen orientation, I can still rotate it to landscape. It's just the screen goes off when the keyboard comes out. I'm afraid it's a hardware issue because I just did a hard reset with the same problems. Anyone else had this problem? It's less than a year old, will Motorola still cover it? I recently moved to Amsterdam and cancelled my Verizon service, so I can't get them to fix it.
