5S, same problem after desperate iOS update hoping for fix of ringtone/message tone silenced during day at work in another city. New problem. Accidentally updated later again and acquired the hypersensitive proximity detector problem (about 1.5”/38 mm).
Updated to 12 hoping for fix and prox.sens. prob is gone, but silent tones problem still present and now speaker phone repeatedly turns on for incoming calls, sometimes ignoring touch screen command to turn it off.
2 cans & a string or Android phone might be a solution. I want my phone to work without software repeatedly ‘breaking’ it with new things I don’t want or can’t disable.
Maybe I got old all of a sudden...but I’m not senile...I can make that can or Android choice. Verizon & Apple are ‘unaware’ of such problems according to Verizon rep on phone last night.
Hey, there’s always snail-mail, right?
