I don't know how to quite explain this, so I'll do my best. I have a Droid X, and I love the phone. My favorite phone. BUT, I had to replace my first one due to an unresponsive touch screen. The second phone was the phone I was suppose to have, but recently, I've been having problems. See, on random occasions, the other line will be silent, either when placing a call or receiving one. No ringer, no voice message, nothing. Just silent, weird thing is, I tested it out on a friend, HE CAN STILL HEAR me on his end, but I can't hear him on my end, even when the call is running (this lasted until I ended the call). When I have this problem, I restart the phone and everything is fine. In a regular area, I'm fine with that, despite the fact its a pain in the butt, but the concern I have, is that what if it's an emergency? Or what if someone important is trying to reach me through a restricted number? I can't answer or place that call without having to restart the phone. Knowing this is a problem, I'm just wondering if anyone else has experienced this??? I haven't returned it quite yet, because it's only happened twice in the past 4-5 months. But if it happens again, then I will definitely take it back in. Also, on a less than important note, also on rare, but more frequent, occasions, both my ringtones and mp3s (or other music/video formats) will not work. It says those files are not formatted for the phone. Once again, a simple restart fixes it. Its odd, but other than these two problems, its been working fine.
