Blackberry PRIV Random resterts + Optimizing apps 1 of 1

Hi All,
I had this problem with my PRIV after recent updates of the Androing core. The phone rebooted a couple of times a day (5-6) at various times. While rebooting it always showed "Android starting, optimizing app 1 of 1" which took about 10-15 minutes. Very annoying.
I went through a lot of discussions and combined the solutions into this one:

1. Install Clean Master Lite and run the system cleanup.
2. Reboot
3. Run a second cleanup with CM Lite
4. Reboot again
5. Settings>App>All apps> Android System WebView - kill it
6. Reboot again

After these steps the random reboot issue disappeared and never came back. Its already one week.

Sounds like a fix! thanks for the info!
