Update: I turned off the Battery Saver, and my Wifi and power button issue haven't recurred for over 15 minutes. The longest I've gone without the problem so far that I'm aware of. Gonna wait a while before turning Batter Saver back on to see if this is the root of the problem, but just a possible suggestion. Will update if anything changes.
My Nokia 928 no longer plays sounds, and when I make calls, the other side can't hear me. The Cortana mic doesn't work either. Also, when I launch music apps (Pandora, XBOX Music), the app crashes and returns to the home screen. When I try the keyboard trick (install a new keyboard), it take me to an update screen that says step 5 of 19. It stays there for a couple minutes and then skips to step 19 of 19 and restarts. The keyboard gets installed correctly, but the sounds still don't work. The odd thing is that there is an unlock sound when the keyboard update is in progress, but no sounds at all after the keyboard update is done.
I'm experiencing random battery drain episodes on my 928. No problems prior to update. Went from 100% to 30% in the half hour it took to do the update, I charged back to 100% and it dropped to 54% within 20 minutes. Several restarts seem to have finally settled it down a bit. I read other posts with similar issues due to account syncing problems, however I did not have that issue on my accounts. Will update if i figure anything out. Love everything else though, especially Cortana control over Bluetooth!!!
i guess ur update is not yet completed...hold on for a while cos the OS automatically re-installs all apps again
Sure enough, 15 minutes after turning Battery Saver back on, Wifi went down and power button issue returned. Also, when trying to turn Wifi off/on in Wifi settings, page becomes unresponsive. I'll update if it changes, but the Battery Saver seems to be the source of the bug.
Half hour later, we're still golden. I wonder if anyone else can replicate this issue. Is it just an HTC 8xt issue, an HTC issue, across all platforms, or just my bad luck?
