Recently I upgraded my S4 i9505 from 4.2.2 to 4.4. Earlier I used Wanam Lite custom rom and now Omega rom.
I faced problems with my phone:
- there is connection loss and problems with wifi (wifi connects and works but it says connection is unstable)
- there is connection loss and problems with 3g/4g (h/h+).
I wonder if I'm using correct modem. I tried searching this forum and google, but didn't manage the find the correct ones.
MY COUNTRI IS ROMANIA
Could you please help me with this problem. Thanks!
