OPPO means the best camera f3plus #
Selfie camera really awesome
Battery backup is very good
And vooc charging is brilliant
Sound is average
Speedy phone
Processer is average
Display is good, not very good
Voice call clarity is awesome
Earphone sounds is good but speaker sound is average
fingerprint scanner is fast, it works very good
Operating system 6.0 is old, not yet 7.0
Design is nice but metal body is average not strong
I think it is a best phone in this range
