Any guess what's this "Media picker" draining battery in SAMSUNG? Turned of sync and everything but nothing seems to work although "Contact storage" stopped draining battery

This green line appeared without even updating the smartphone. When will samsung accept their fault and provide free replacement just like the S series 

There's this contacts storage which drains up battery alot. I've tried everything even had reset my phone but yet it's not solved. I have turned of contact sync. Checked all applications which uses contact but can't find the problem. There's no third...
