Talking about one plus 2 is a 20k+ smartphone which works on android lollipop and upgradeable to marshmallow. It comes with 3300 mah battery, so battery is not an issue. The sandstone black cover makes it good appearance and texture. Volume and power key is at right side whereas you can on/off notifications with the help of slider button at left side. It comes with non expandable memory of 64gb with 4gb ram and 32gb with 3gb ram.
