Hello,
I just unlocked my Galaxy S4 with the unlock code from t-mobile. After that I installed Lollipop 5.0.1 and I'm able to use different sim cards from different providers.
The problem is that when I lock the mobile I lost the mobile network connection (wi-fi remains on). After unlocking the screen, sometimes the mobile connects again but other times I have to enable and disable flight-mode to get connection.
I have tried clean installation of several roms (imperium, lollirom, CM) but to no avail. I don't have anything like juicedefender or any other battery saving app, just the stock apps from these roms.
Best regards, I hope you can help me
