Currently I am using this phone. Let me tell you some features about my phone.
Sound quality of this phone is good. it is also user friendly. I still found no issues in this phone. It can look similar like samsung mobiles. Having 5.5" display. Battery backup is good. lasts for 1 day when get fully charged. The main features of oppo is taking selfies and group selfies with very good pixels.
Wonderful phone made and other features are awesome. you will never regret, if you are having oppo.
