I recently installed Omega Rom v19 (Android 4.3) on my Samsung Galaxy S4 i9505 Intl.
All of a sudden it loses cellular connection instantly whenever I lock the phone with the power key. It will take a couple of minutes before it will come back and this is REALLY annoying.
Any help on this would be great, could it be a modem issue? My baseband is I9505DVUAMD8
I installed a 4.4.2 Google Edition Rom prior to this one and it did the same thing, I have no idea how to fix it!?
