Hello friends,
So oppo R831K is the phone which will take your money but wont survive much.
This phone has no 4G service, 5MP flash camera which clicks pics worse than the VGA camera. OS is kitkat 4.2 . Phone lags or hangs on every other app. In whatsapp when you start typing very fast it stops for minute and than when you have stopped typing it will type the letters you were typing previously. Touch response is as late as 3-5 seconds. Not very user friendly interface and not very smooth in touch and play. Most of Apps wont work out because it have only 1 GB RAM and only 4GB ROM. Sound recpetion is average. Other features like bluetooth, EDGE, GPRS , GPS etc are of older version. The main problem is its price. Which is 10999. In that amount you can have other phone with better quality of features and assurance. Phone is bit uncomfortable in hands because of pointy corners . Design and layout is not so much unique and definitly not value for money.
Thankyoy
