How to fix "Unfortunately, Google Play Services has stopped"? I am using a Sony Xperia C3 running Android 5.1 Lollipop. I had done a reset of my phone as it was getting hanged. When the reset completed I tried to assign my Gmail ID with the Play Store but at the final stage it says 


  Unfortunately, Google Play Services has stopped 


I tried every option shown on your website but the problem is not solved.
Try this solution.


Clear cache the Google Play Service 



  Settings > Apps > Play Service    > clear cache



Clear data for Google Play Service.
Clear data Google Product and Media Storage
If not , try and reset/factory reset phone again.
If still not working, flash official ROM on it
