Ever since yesterday when I updated my phone's OS, whenever I get an incoming call & answer it, neither party can hear each other- it's like both are muted, no sound at all, but it stays connected until one of us hangs up.
If I reboot it works until I check my voicemail and the call to voicemail fails for whatever reason, then it goes back to not providing sound either way on incoming calls.
Then I reboot again and don't check my voicemail & it stays functional for a few hours then goes back to not allowing incoming calls to exchange any audio.
This is awful!
How can I revert back so I can use my phone?
I haven't heard anything about those issues at this time. I do apologize for any inconvenience this has caused you.
I would recommend you visiting a Service & Repair location www.sprint.com/storelocator?ECID=SM:BW:20120319TORELOCATOR.
It stopped misbehaving after about a dozen reboots & after I cleared the voicemail. It seemed as though the voicemail was acting up & that triggered the behavior. So it's been fine since I cleared the voicemail.
I haven't let the voicemail build up again since, so I don't know definitively if that's part of the problem. But it's been okay yesterday & today so far, so I won't be travelling across town to visit the Sprint repair shop, but I definetly will if it happens again. Thanks.
