It feels like it was just yesterday I was listing the problems with my HTC Evo 4G. Now it’s time to start looking again – my Samsung Galaxy S2 has started acting up. The battery was really low (close to dead) last night, so I plugged it in next to the bed and set my alarm. This morning, my alarm didn’t go off. I picked up my phone to check the time, but the screen wouldn’t come on. I could see by the indicator light that the phone was still on, but my screen remained black. I tried unplugging it, which usually triggers the screen. No screen. I took the back off and popped the battery out. Battery back in, push the power button, and there’s my screen! Of course, it’s going through the power-up process, but at least it’s there. And it’s been there all day, off and on like it’s supposed to. The black screen followed by battery thing happened to me a couple of weeks ago, too. Maybe I just need a new battery, but you know what? I’m due for an upgrade. After reading CNET reviews all day, I’ve narrowed down my choices to three: the HTC One, the Samsung Galaxy S4, and the Google Nexus (that John just got). My work phone is an S4, so I can play with two of the three before I ever set foot in a Sprint store. If anyone has any advice, I’m all ears.
