Dear all,
unfortunately, during a visit, a child who was there completely messed up my cell phone settings. So far, I've been able to reset everything except for the phone app. As soon as I dial a number or someone calls me, it's as if I or the caller immediately hang up. It doesn't even ring. Nevertheless, I or the person I called receive a notification that there is a missed call.
Resetting the network or app settings did not help. Does anyone have any idea what settings need to be set in the phone app (or another app) so that I can make calls?
Everything else, such as Signal and Telegram Fork, works perfectly.
Thanks in advance,
Linuxfreak
