I received my 3rd replacement Droid Razr xt912 yesterday because every Razr I've had has had a screen freezing problem. Now this latest Razr has the same issue. Verizon Tech told me it was due to 3rd party apps on my phone? What's the point of having a Razr and no 3rd party apps???!!! Has anyone else had a problem with their screen freezing up when calls come in, or when trying to retreive voicemails with *86? Also this latest Droid Razr xt912 is draining my battery rapidly. I have the latest update, installed it yesterday. Thanks for any and all help or suggestions. Verizon tech also told me I did not need webroot antivirus, or any antivirus for my phone. Any thoughts on that also appreciated.
