Ring tone not coming on my iphone 12
I use iPhone 7. For last few days the ringer is not working. The silent switch is "Up" towards screen as per general guideline given in various sites. I tried removing and re-adding "vibrate on call" option but still ringer doesnt work. On pressing the up or low buttons a ringer symbol is shown and is crossed in red. And it doesnt happen consistently. But when I take the call I am able to hear clearly and speak. Also I diont hacve problem when playing music, aiduio and video files on whatsapp/ Youtube and other apps.
When I move the ringer volume symbol up or down the ring tone works. any suggestions? could it be a hardware issue of the silence switch? I tried in both positions but no difference.
iPhone 7, iOS 15
