Oppo Neo 7

The Oppo Neo 7 is the last phone in the Oppo Neo Series, before the series became known under different aliases, such as the Oppo A Series. The phone was available in two configurations: a 3G and a 4G model. Besides network connectivity differences, these models also had different chipsets. Oppo says the reflective back on the phone, which is made by a "special laminating process" is inspired by Chinese bronze mirrors. The phone is aimed at people who value the looks of a phone over the raw specs, since the price is higher than other phones with similar specs.
This phone was released later as Oppo A33 in November 2015 but with 146g of weight, Snapdragon 410 chipset, 2 GB of RAM and a less 2400 mAh battery.
