Sound quality is good but not the mark.sometimes mic entrupt.
Os is based on andriod but no so much easy to use.we have to use this device for 2-3weeks to remember everything.
Style is good but quality used by oppo is not that good and final nd finishing is also not good.
In this device specification is okay you get good camera and selfie camera too.
Battery drains fast it gives you only 4hours screening time which is not upto the mark.
Cost is bit high because in this range you can get much better device.
If u want as a camera then u can go for it otherwise dont.
