http://forum.xda-developers.com – Hi all, Last week I upgraded my Note to new LT4 rom.(s). Couple of days later, my Note was unable to make calls. When I try to make call or receive a call, there is no sound neither from earpiece nor from the speaker. If I reboot the phone I sometimes be able to make some calls with a great noise on the background then it stops. I re-flashed the rom and flashed other roms even re-flashed LZS roms with all clean install even finally formatted the internal sd card . No change. Since I can make one-two calls after each reboot I still think it may be a software issue rather than hardware. All (HowTos)
