The only reboots I've had were with the camera app. Fixing the lag and LP problems can be done by installing Script Manager from the app store, then downloading the V6 Supercharger script and choosing option 6. Reboot, run it again, option 6 again. Each time you reboot, just give the script a run. Cleans up a lot of the performance problems. It's recommended that you NOT have the script automatically run at startup in case something goes wrong. You must be rooted.
