I updated my LG G3 Vigor recently and now it wont work at all.

[AC Question]

I updated my phone because the stupid notification kept popping up. Now the 3 apps I use most wont open. I've uninstalled and reinstalled all 3 apps several times but they still won't work. What can I do?

Welcome to Android Central! What 3 apps are they? Are you reinstalling them from Google Play Store, or from some other app source?

After an update it's a must to do a factory reset.
I upgraded my G3 from Lollipop to Marshmallow and after that I made a factory reset.
