the default is non-speaker, so you have to very quickly put it on speaker, or go back and put it on speaker.... it goes black too fast when on non- speaker...and it does so even if the phone is lying flat on its back .Is the vm app going blank when listening to a message when you put the phone on your ear, or in speakerphone mode also?
If listening in your ear, the prox sensor turns the screen off so you don't touch vm functions. (unlike the old version were I kept touching buttons while listening to my vms)
For those experiencing battery drop quicker than before and are in areas with no LTE yet (like here in Phoenix), the upgrade to Jelly Bean reset the "Network Mode" to LTE/CDMA which would leave the phone continuously scanning for LTE.
To set it back: Settings>Mobile data>Network mode>CDMA only.
I contacted HTC today about the proximity sensor issue and got this reply on factory resetting the phone and wiping the partition. It didn't work for me but I thought I'd post it in case it helps others.

Day 2 after the update and we are already up to 305 posts of bug issues. HTC had all that time to get this thing ready. Even would seem that they gave themselves an extra month what with the first leak on the release dates. Yet here we are.
Well, just imagine how it would have been, had it been released back then....
So I followed these instructions to try to get to the wipe cache and when I hit factory reset, it reset and wiped my phone.
Proximity sensor problem not resolved but working a little better.
The proximity sensor settings coding must be wrong because when I am in very bright room there is no problem. Even at dusk time brightness the proximity sensor fails.
This is how is working for me at this time.
Voicemail screen blackout still happening.
Google maps not smooth and nav is still freezing and crashing.
HTC get on it!
Is anyone else noticing a lot less ram available now? It's almost back to the way it was before the last update when I check it....and that's after having much less apps on my phone since I've wiped it clean several times now and haven't reinstalled everything.
After hard boot my GPS still crashes a loy Almost got into an accident on fwy
