The newest and master of all Android operating system as of today is the Android 6.0, easily nicknamed "Marshmallow". Sometimes last month, we were meant to believe that marshmallow update will come to Android one devices like the Infinix Hot 2 next year being 2016 but the good news and surprising thing is that the update is already rolling out on some Android one devices including the Infinix Hot 2.
According to Androidpolice, more phones are going to receive the much awaited Android 6 update from December 1, 2015. So get ready and set your device to be in good condition for it. If its rooted, you are advised to unroot it unless you are comfortable with your current Android version. Have a nice week ahead.
