I have a Sprint gs3 on android 4.4.2, and just within in the last day or so if I make a call then promted to press a number for an option, the touch tone won't go through.
For example if I dial Sprint and get press 1 if you are calling about (my number) and I press 1, nothing happens. I dial other numbers and nothing. Also I've tried other calls and the same thing so it's not Sprint's system.
Customer care did a master reset and I tried some 3rd party dialers also and nothing.
Thanks in advance for any suggestions..
I also wiped cache partition. Samsung support advised me to go to best buy for a software refresh..
My girlfriend has the exact same issue on her gs3 and we're on the same account.
