Heyy Guys, I would to tell you something about my knowledge and experience whichi I have done with OPPO R831K. OPPO R831K is a Wasting of Money. This Phone is really Bad.
First of all, Camera Quality of this phone is fine in day but not good in night, because we cannot take good picture in the night. Music Reception is Bad. Processor of this phone is cheap. All the networks are nit available. So we cannot take the advantage of 4G Sim card.
On the other hand, Battery back-up not good. It costs too much. So Value for money is not reasonable according to the features. It's just Wasting of Money. This OPPO R831K is not a recommendable phone. Don't ever purchase this.
