Hi friends I used this phon almost 6 months in last year. I suggest you to buy another oppo model instead of this according my experience. Sound quality is just not too good on high volume .it is not user friendly.it is not fit for running big Mobile game ever it came with 1gb RAM and quad core 1.3GHZ processor. The battery of this phon is bad. Style and desin is not good. I recommend you to don’t buy this phon thank you.
