Got this as a present 2wks ago. Upgrade from R7 Plus. Quality phone but the battery life is not as good as the R7 Plus. Screen is smaller however a good phone nonetheless.

Pros: great camera, extremely fast charging, nice display, came with a high quality case Cons: OS appears to be a cross between Apple and Android Used for a couple of weeks so far, still very impressed

Excellent, I am very happy with this phone

Oppo is turning them over fast, and it seems to be paying off. According to Counterpoint Research data, the Oppo A57 phone – reviewed here – was the fourth biggest selling phone globally in July this year, and the second biggest Android model.

Great value for money; fine screen; good overall performance; strong camera performance; ColorOS 3.1 may make Apple to Android transition easier

Affordable phones are getting better and better, so there's never been a better time not to pony up for a pricey iPhone or Samsung Galaxy S. The latest budget phone to impress me is the Oppo R11, a solid 5.5-inch device with a great camera and impressive battery life.

The Oppo R11 has terrific rear cameras; long-lasting battery and an affordable price

Priced at $649, the Oppo R11 is designed to attract a customer that doesn't want to pay more than $1,000 for a smartphone but still...

For a while, we've had OPPO phones that had not really changed much apart from having better performance and a few tweaks here and there. OPPO R11 is a game changer for OPPO by introducing an all new bells-and-whistles feature: dual cameras with enhanced bokeh effects; turning your ordinary...

It's not the easiest phone to get hold of, but Oppo's R11 is another feasible, affordable alternative to Apple and Samsung.

OPPO certainly isn't a name we hear very often in the West. Travel pretty much anywhere in China, however, and you'll be amazed at just how much you see the italicized green logo. OPPO's targeted success is understandable.

Great cameras Premium; all-metal design Quick fingerprint reader Good battery life VOOC fast charging Expandable storage

Poor software user experience Mediocre performance Display lacks oleophobic coating microUSB is outdated 3.5 mm jack has limited compatibility No NFC

While Xiaomi has the lion's share of the Chinese market and fellow Chinese OEM OnePlus making waves in the international scene, OPPO remains undoubted and produces a steady stream of smartphones every year.

Almost all-day battery life; Responsive even with multiple apps; Decent camera output; Affordable price

Micro USB only; Less than stellar low-light camera performance; No image stabilization
