Hello there, i am experiencing problems with network operator selection. Phone searches for networks and after few seconds, error is shown. When i am in areas with low signal, phone automatically goes to roaming and then i have problems setting back the default network, because operator selection is not working. Sometimes, quick change from 2G to 3G and back helps.
Also while using GPS navigations, GPS is periodically losing signal for 10 seconds. It is really annoing when using navigation in big cities, it freezes a lot. GPS signal is not the problem, tested in clear areas with excellent gps signal. It was not doing while i have been using stock rom.
I tried using thunderzap and phantom kernels, no change. Fix appreciated.
