Problems: Data Connection and Screen
I just had to get a "like new" warranty replacement for my Droid Razr after the headphone jack on my old one stopped working. So, I'm pretty sure I followed the protocol correctly for swapping out the data sim thingy (what's that thing called?) and the Micro SD card. Power down old phone, remove thinigies, insert thinigies into new phone, power up new phone. Right?
Anyway, so I reinstalled all my apps and stuff, and now I'm having a few new problems.
The most annoying is that my data connection dies often. Rebooting the phone restores it, but then within an hour or two, it goes away again. Going into and out of airplane mode doesn't fix it. But, sometimes when I try this anyway, and I come out of airplane mode, I get a little icon for a few seconds that looks like a Sim or SD card with a (!) thingy overlaid on it. This makes me wonder if my Sim got messed up somewhere along the line.
The other thing is, when I turn off my phone (not power down, just turn off display), sometimes the screen will randomly come back on of its own volition. Huh? Why would it do such a thing?
Oh, and according to Settings > About phone > System updates, my system software is up to date.
Anyway, any help would be appreciated. I don't wanna have to go through the warranty replacement again if I don't have to...
