I have an s4 from rogers (Canadian model) and initially had cyanogen mod as my rom but I realized that I was missing nearly 5 GB of storage on my phone. I read that to fix this I had to go back to stock using Odin. I went back to stock 4.2.2 using Odin, but then my WiFi stopped working. I couldn't turn WiFi on or search for networks. I then rooted my phone and installed a rom and my WiFi problem was fixed, but now I cant make calls. Every time I try to call someone my screen goes black and the recipient cannot hear me and I cannot hear them. Also, the sound on my phone does not work. I have flashed multiple roms and still get the same problem. Does anyone know any possible solution. I have looked around and many people have had the same problem, but no solution. Any help would be appreciated.
