OPPO HAVE 2GB RAM AND 5 INCH SCREEN, 2 GB RAM IS GOOD FOR PERFECT GAMING. OPPO HAVE 2630 MH BATTERY THAT IS ENOUGH FOR WHOLE 1 DAY. OPPO HAVE 16GB INTERNAL STORAGE AND ALSO YOU CAN ATTACH A MICRO SD CARD UPTO 128GB. CAMERA QUALITY OF THIS MOBILE IS AWESOME, IT HAVE 8 MEGAPIXEL REAR CAMERA AND 5 MEGAPIXEL FRONT CAMERA.
