Got 5.0.2 OTA yesterday. Initially all looked good, until I started Facebook. It took >1 minute to start, and was very laggy after it did. Also took >1 minute to shut down. After shutdown, everything on the tablet was very laggy. I forced stop Facebook and then the tablet's response was good. I started Facebook to test this again and had the same result. I then uninstalled Facebook and restarted, and then the N7's performance was good. Anyone else seen this?
