[Q] ZR dropping the network
My xperia ZR (C5503) is dropping the network. It is showing signal strength and that changes, the 3G symbol pops up and dissappears as normal, but I cannot send/recevie text, calls or mobile data. I have turned the phone off and taken the battery out. I have used PCC and SUS and I have also replaced my sim........the build number is 10.3.1.A.0.244
It will drop off the network, then a few hours later, pick the network back up and the phone will be useable for 10 mins, then no network. The phone worked great for the first 2 weeks and has started doing this.
I only have about 10 apps, have not changed any admin settings etc.........any help is greatly appreciated.
