I have a rooted MF3 Galaxy S4 and my problem is that I don't have gps anymore. I have Safestrap installed and after installing any custom roms, I flash the proper module, so that everything works, like wifi, etc. Even if I go back to my stock rom, I have no gps. I've searched (XDA and Google) and haven't found any similar problems. Has anyone come across this problem and found a fix for this?
