has the same issue.

Check button on upper left side of phone

If you move it toward the screen, it rings. If you move it away from the screen it silences the phone.

I have no idea what it does.

It's completely inert.

The photo looks nothing like what I have on mine.

Thanks anyway!

restart it.

Only trick I know.

to take to find the reason and correct it: (the most obvious would be if airplane mode had been toggled on but there are others). Also read the section about toggling FOCUS mode on and off (a pretty recent feature that is not hard to accidentally activate).

Thank you.

ring. I caught a call when I saw the light from the notification but no ring.. I'll do the on/off think..

And new things learned.

Go to settings.
Select Phone
Look for Silence unknown callers.
Set toggle to off.

If this function is on, when those in your contacts call. It will ring otherwise silent.
If this function is off, all callers will ring.

If your daughter's call rang, that would indicate this is the problem.
