I did the 3500.c update on my xv last night as well & saw the same today screen 'corrpution'. So then I wondered about it a little more. So I did NOT do a hard reset, but instead clicked into the corresponding apps underlying the corrupted screen areas (I had 3 apps). After that, everything repainted w/o a problem (so far).

So it make me wonder that the BT stack upgrade changed the screen paint location(s) (e.g., reloacted stack/heap space I'd guess?) just enough to need the repaint.

But everything appears to be ok & that was w/o a hard reset & reinstall, etc.

Oh yea. And my BT interactions (limited so far to Nextlink AX a littel last night tho) appear to be fine.
