Xperia Z3 :: Apps Keep Closing As Soon As Opened

This problem popped out if no where, my z3 battery died that the phone turned of so I plugged the charger and waited for it to charge, I booted the z3 as it finished charging and had this

"android is upgrading...
Optimizing apps (number) of 314 (sometimes 315,316)"

I though it's normal and it may happen from time to time to improve like the phone blah blah so yeah I rebooted my phone after a while and it did the same thing tried again and did the same thing, I didn't pay that much attention because it's rare that you reboot the phone or need to and when I can wait BTW IT TAKES LIKE 10 MINUTES

Once I had to open the camera to record something very important I opened it but is closes immediately again and again and then I noticed this with very various app pre-installed or not happens with albums Google Facebook it's so annoying.

By restarting it works temporarily but GUESS WHAT THE OPTIMIZING PROBLEM IS THERE I'll wait 10 mins. And sometimes I get a call but It doesn't show the answer or reject page.
