Hey friends,
I am Using v5 plus,
but just yesterday I was opt to update the system optimization, as of writing I haven’t no bad experience just the usual usage. My only concern is the themes ( yeah right very pity concern) as I have read the optimization one of which was to generate more themes but as of checking still no additional themes. BTW, do you have plan to upgrade the 6.0 to 7.1.1 Nougat? Just don’t be too left behind, this unit specs is better than the HTC one M8 but receive the nougat update. You can have more sales if you do update the OS to most recent versions.
