Nexus 5 Android is starting Optimising app…

My Nexus 5 has had a restart problem for several months now and since it’s my secondary device I didn’t report it but I’ve had enough now!!!!!!!

The phone restarts frequently and randomly without any prompting to do so and on occasions it resets some of my information such as WiFi credentials.

When it restarts its keeps saying: “Android is starting Optimising app…”

This is the worst experience I’ve had with a smart phone and this being my first transition from iOS to android it isn’t a good look. I don’t know if it’s a universal issue but I certainly hope it can be fixed because I really like my nexus and need it for development!!

PLEASE HELP!!!!!!
