My phone keeps beeping when I get a notification or even phone calls or texts. It's really annoying. Also can anyone tell me why my phone will not show a missed call
Sounds like you just need to fiddle with your settings there. You can open phone app and find ringtone and notification sounds..
Or you can do it from sound and vibrations from your settings menu... Not knowing what phone and software you have, I can only be generic..
Showing the missed calls will be under notifications as well, you can set it up to pop up on lock screen...
