Network problem. I am using Jio sim in my redmi note 3 it was fine where the problem is when Jio sim network drops and comes for a few minute my mobile shows in emergency calls or no service until I restarted device it doesnt connect network again. first I thought Jio problem but frequently my bro also using Jio and he uses let 526 mobile he get network immediately. and I also checked in network settings and kept auto connect network but no result and I feature I didnt expect from Redmi is feedback app is fake. I had seen in app settings about feedback app there is disabled feedback app button on my device. Pls show solution
