Back then everything felt fine. However, since upgraded to android 5.1.1 , apps has been running slow (such as tumblr ) and more time needed when turning on the device ( words like "optimizing Z launcher for you " is seen ).
Thats not the most serious problem , only a specific older version of instagram installed using apk could be launched , other version would just closed itself. And that version of instagram would cause device to freeze and hang at spontaneous time, and forced reboot would be needed and that's very annoying.
I have installed an app called clean master but my problems werent solved.
