The things bad about this phone is more than good thing and overlaps all the plus points of the phone. I would start with
1.interface not user friendly:- the interface of the phone is boring and the os which is oppo’s own os is not at all satisfying. this gets boring in the daily use and is little bit difficult when we start using it.
2.danger of damage:-there remains always a danger for break down of back screen and replacement is only free for 1 year and then it is very costly.
3.other features:- there are not many features in the phone.it does not have split screen option and also does not contains many features the one phone at this range should have.
4.value for money:-this phone is not a such phone which makes each and every penny used or satisfied .
5.deal maker or breaker:- no not at all this is worth it and not a deal maker for me
