You really should post HOW you resolved it.
I make no secret that having owned THREE of these duds, I consider the
6700 to be probably the WORST phone EVER! In fact, I just physically destroyed mine after two Verizon replacements... NO MORE, EVER! Not remotely worth the endless bugs, hassles and pain.
Mine would occasionally do the same thing - turn the brightness all the way down without rhyme nor reason - except mine would be so dark that you literally could barely see (if you were lucky) to get into the settings section to turn the backlighting back on.
Hope you have better luck with the 6700 than I did, although admittedly that wouldn't take much.
