It's been a long journey.
Went ahead and performed the manual update (update.zip)
After several issues - Calendar Sync, Market Sync, Old Market (not updated after 4 days), slow rotation between portrait & landscape, sensor issues, etc. I worked my way through most of the fixes presented on Android Central.
I'm down to one issue that I have not seen anyone else mention: The phone vibrates after I turn it off (about 10-15 seconds after the keyboard turns off, it produces a short vibration), and when I turn it on (right after the Galaxy S turns off).
I backed everything up and did a factory reset - no fix.
I bit the bullet and tried to Odin the EB13 'fresh' - no fix
I used Odin to go back to DI18 and verified that the vibration did not occur.
I used the update.zip on a clean phone to go back to EB13 and the vibration happens again.
I even went so far as to Odin to DI18, then Odin again to EB13. Again, at DI18, no vibration on power up/down, but on EB13 it happens.
I've played with the vibration settings, but can't get it to stop.
I guess its minor compared with some of the other issues seen, but its a little irritating since it didn't do that before.
Anyone else see this?
