I got my Atrix 2 a couple of weeks ago and I really like the phone. However, I've noticed that randomly I will completely lose signal and in place of a 4G symbol with bars I will have either a red circle with a line through it or a gray box with a red cross in it. This has happened even in places where I would normally have signal. I have these symbols and no signal for a short period of time (a few seconds to a minute or so) and then my signal will come back. Has anyone else experienced this? I don't know if this is a phone or an ATT issue. I search and it seems that owners of the original Atrix had a similar problem. Thank you!
