Samsung galaxy on7 is a wrost set of Samsung.
Its features is not good like there is no led notification light with the divide. Main and important problen is that its charging issues its takes lot of time for charging.
And its display is not too safe because here is no corning gorilla glass on display.
And other problem is with the chipset which is only a Snapdragon 410. It is quite an old chipset which is now more than a year since its launch by Qualcomm.
For normally gaming its good but for smart androide games definitely not recommend to play here.
Overall on7 is wrost mobile by samsung.
