Finally talked to HTC about the following issues since JB update
1. Proximity Sensor
2. Voicemail Screen going black
3. Google Maps/Nav Crashing
They will not acknowledge these are known issues. They deny deny deny.
Their answer?
Wipe cache Did not work
Safe Mode Did not work
Factory Reset Did not work
Great! Good bye HTC
Weird. Whom exactly did you speak to. I spoke to someone in their escalations department the other day. I had already gone through the other suggested process of wiping cache, safe mode, factory reset so they advanced my ticket to a higher priority. I was specifically asking them about the proximity sensor issue(which I assume is one in the same with the voicemail issue being as it is phone call related), they fully acknowledged that this is an issue and that they are working on it. The rep went so far as to say they are trying to find a fix that the users may be able to do themselves with a set of instructions and if not it will be released in a future maintenance release.
I do have a question about people with the navigation issue though. How many people actually hard reset and wiped the phones cache on their phones and DID NOT put any app whatsoever on their phones before verifying that navigation was crashing( I hard reset and wiped my phone cache several times without putting ANY apps on my phone to check that my proximity sensor issue wasn't app related)? I'm not trying to be presumptuous here as I myself swore up and down I was in the camp of the nav crashing group. In my case I was able to pinpoint that using an Equalizer app was causing my navigation to crash among many other issues. Actually 2 equalizer apps gave me issues with navigation but one went far worse than the other
Personally I believe there are many many apps out there right now that aren't working correctly on our phones just yet and are causing many issues people are having. Just this one app was causing my music to skip when driving with the navigation maps open and on the screen, was crashing navigation, voice search, Google Now, voice dialing, force closing itself, completely locking my phone up. I unistalled the app, phone worked great for a day, reinstalled the app, and all the issues came back. And this was an app that worked just fine on ICS Just my two cents.
