I just reset my phone and its OK now but before I reset it,
people would call me but the phone wouldnt ring.
If I called myself with my cell phone, it wouldnt ring.
If the sun shines on the phone, it will appear as if Im on the phone (the END CALL) button shows up but Im not on the phone. Yeah I know this is a weird one but I even videotaped it because it is so bizarre. No sun in Maryland the last few days so it hasnt happened.
I have to reset my phone every single day and usually that resolves it but not always.
