Like thousands of others, I've had multiple issues since the 2.1 > 2.2 upgrade, including freeze-ups, general slowness, Bluetooth connectivity hell, and ridiculous battery life.
Since some other minor work-arounds have been effective, I'm anxious to see if a new work-around I just saw (in a Galaxy Tab thread, yet referring to the Fascinate) may or may not help -- a suggestion to remove the "feeds and updates" widget due to some issue with the Facebook news feed.
(I'm trying several things, but hoping to avoid a hard factory reset, not wanting to chance problems with backing everything up.)
Here's another temporary fix I had success with, for the issue of horrific battery life with the 2.2 upgrade -- Go to Settings - WIreless & Networks - Wi-Fi Settings - Advanced, then set "Wi-Fi Sleep Policy" to "when screen turns off" instead of the default "never". Uses noticeably less battery that way.
I also saw some minor improvement in speed by going to the RAM manager tab (in Task Manager) and occasionally clearing both Level 1 and Level 2 of RAM.
Another issue I haven't yet figured out, though, is a Bluetooth connectivity problem with my Ford Sync in my car. Maybe about 30% of the time, the Bluetooth won't connect, or actively disconnects the phone. (Rarely had been a problem with 2.1.) Only gets fixed with a complete reboot, or sometimes by turning Bluetooth off, then on again, then it ALWAYS force-closes, then turning Bluetooth on again. Ugh.
But obviously, this OS SHOULD work properly without having to jump through ANY of these hoops.
Throughout this forum over the past month or two, I've seen multiple promises from Verizon, saying that Samsung was working on a fix or update for all of this. Whether it would be in the form of a patch, or perhaps a direct upgrade to Gingerbread 2.3, ANYTHING would be appreciated.
Does ANYONE have any word on progress towards a fix? There are truly THOUSANDS of dissatisfied customers suffering through these multiple problems.
I'd even be somewhat reassured if another Verizon rep posts here, even if just to say that Verizon and Samsung are indeed still actively working on it, not just cutting us all off into oblivion and hoping the problem goes away.
