Mobile data and Wi-Fi turning on automatically in Samsung Galaxy S3 My phone turned on Mobile data and Wi-Fi automatically. Battery also drains very fast. I checked "Mobile network usage", and turned it off for some  apps, but suddenly, I started to receive messages  "Unfortunately,  Google apps have been stopped". 

I don't know what happen. What should I do resolve the issue?
As per this Thread problem was solved by below steps:


Go to Menu 
Settings 
More Settings 
Mobile Networks 
Connection Optimizer and uncheck Sprint Connection Optimizer
