All of a sudden a lot of apps don't work any more, and some randomly give messages "unfortunately ________ has stopped working". Is there any way to go about trouble shooting this?
Shazam and Strava do this a lot. Facebook is unstable and closes unexpectedly. I restored from a working backup, but it was actually after this that things started to go wrong.
Firefox would never connect to the internet.
This is Android 4.4
