I used to have missed calls on my phone when I left it idle. It came to my notice when it happened while I was using my phone. It ringed for a second or two and rejected the call. I’ve checked everything, no one’s blocked and the signal strength is good. It happens with all the incoming calls, not a particular contact and it happens very frequently, atleast 6-7 times a day. And same problem with one of my friend using nothing phone 1. Any suggestions?
