Hi All, I am using Xperia Z1. Recently i updated it to 4.4.2. Before this update(i.e in 4.3) my ram usage never crossed 75% for how i used it. Now after updating to 4.4.2 even when there is no app running, the RAM usuage goes to 80%+ If i restart my phone it comes down to 55%. In next 1 or 2 days it goes back to 80% I dont get y this is happening. Any idea? Note: i have not installed any new app after update. Also i am checking the RAM usage in Clean Master App.
