[abhi_khurana]

Hello guys, i hve t2 ultra dual as i has dual sim option bt whenever i use dual sims my phone hangs during the calls. Also the voice quality become low whenever i uses. Durung a call it tend dat the phone has weak network and voice cuts during the calls. Bit whenever i ises single sim....no issues with the voice and call quality. I also visited services 4 tyms....no solution has been provided except rebooting the phone.

Does rebooting help? what if you reboot on safe mode? if that doesn't work then repair your phone with PCC and do NOT install any app and test your phone for 3 hours w/o installing apps
