the version number being 220.127.116.11(C675E4R1P1).
This cause my phone to become unstable, and simple things like camera were not working, there were random snoozes and sometimes the home launcher would not load, or the apps drawer appeared to be empty. i was using the stock home launcher.
Well a factory reset fixed the problem.
hope this helps someone else facing the same problem, also there was a mention in one of the previous updates, to not use third party launchers. Don't use third party launchers, if you are already using then uninstall before any update then reinstall after the update.
