Oppo isn’t a particularly well-known name in many Western markets, and that’s hardly surprising considering the Chinese company hasn’t been around for as long as the bigger players. What it is known for is offering ‘bang for your buck’, and its latest R7s model is no different.

Priced at $399, it sits as a midway point in Oppo’s range – between the R7 and the R7 Plus – and goes up against similarly priced devices like the OnePlus 2, HTC One A9, and Nexus 5x, to name just a few.

It’s a busy space, and with little brand recognition, the R7s Lite has an uphill battle to fight to break through into the mainstream.


Design and hardware

The R7s’ design is one of its stronger points. The OnePlus 2, for example, can’t boast the same unibody metal chassis design as the Oppo.

It’s thin too, at just 7.5mm thick, which is the same as Huawei’s Mate S, 0.4mm thicker than an iPhone 6s, or 0.1mm thinner than an iPhone 5s.

From a distance, if you squint, you could be forgiven for thinking you were looking at the front of an older generation iPhone, but then that’s a criticism that can be levelled at some other devices too – and so hardly holds the R7s back.

It’s only available in the ‘rose gold’ color scheme too.


Ultimately, it feels like a premium device in your hand, without weighing too heavily in your pocket (it’s 155 grams) and that’s not always easy to achieve.

The slimline design and metal construction did make it feel quite droppable, so using the included transparent case might be a good idea if you want to keep it scratch-free.

The display is a 5.5-inch full HD AMOLED touchscreen that uses Gorilla Glass 4 and offers 401PPI (Pixels Per Inch). That’s the same as an iPhone 6s Plus, and more than the iPhone 6s’ 326PPI. If you care about screen specs above all else, but are working with a slightly constrained budget, you could certainly do worse than the Oppo’s.

On the rear is a 13-megapixel camera sensor, which places it firmly in the mid-range in terms of resolution, and there’s a forward-facing 8-megapixel snapper.

Keeping everything ticking is an octa-core Qualcomm MSM8939 chipset, 32GB of onboard storage and 4GB of RAM.


Down the right side of the device you’ll find the power button and dual-SIM slot, while the left houses the volume rocker.

However, you’ll have to make do without luxuries like a fingerprint sensor and NFC, which is a definite downside for potential Oppo purchasers.

A single speaker sits embedded in the base of the phone, while the headphone socket is on the top, where I prefer it.


At its core, the R7s is based on Android 5.1 but it arrives with Oppo’s ColorOS (2.1) in tow.

It’s not a fork that detracts from the Android experience, but it’s also one that’s still growing, so can’t quite be considered as offering anything utterly invaluable for most users either.

Many of the visual elements of the Android OS have been tweaked for ColorOS, and in many cases this is for the better.


Among my favorite features are the screen gestures. With the screen off, you can do things like set a specific app to launch whenever you draw out an ‘M’ shape, or open the camera by tracing out a ‘C’. You can’t modify the M to a different symbol or letter though, so I chose to associate it with messaging.

There are also different gestures you can use when the screen is on, like drawing a line diagonally up to the left from the bottom right-hand of the screen to quickly shrink the overall UI into one-handed mode.

Tapping what you think will be the recent apps button (bottom left) doesn’t bring up the apps list you might expect if you’re on the home screen – to do that you need to long-press it. Tapping it only brings you to the homepage and theme settings, if tapped from the home screen.

Tapping it while in another app brings up the contextual app menu options, essentially mimicking the three dot menu button found in most apps.


Another thing I’m happy to report after using the Oppo R7s as my daily device for a few weeks is that it never hung or left me waiting when opening or switching apps. I appreciate that in a device.


There are other occasionally useful, if not revolutionary tweaks to discover throughout the device, like the ability to take different types of screenshots by holding the power and volume up key, like if you need to capture a section of a single Web page. You can also take a regular one by holding power and volume down, as normal. The granular power-saving options, which include under-clocking the CPU to use less energy can also help you out in a bind too.


There’s also a mode designed to reduce the potential for eye damage from staring at your phone for too long.

Living with the Oppo R7s

Any Android user will feel at home with the R7s. It’s a different set of paint with the ColorOS, but Android’s essential roots are still present. You’re not going to feel lost finding your way around, and the bright, crisp full HD display doesn’t disappoint.

For people who like to play around with the customization options, Oppo makes it incredibly easy to find and apply a new theme across the whole device in just a few seconds.

It’s also easy to re-arrange your homescreen icons by grouping them together and moving them in one go, rather than having to arrange them individually into folders. That’s particularly handy if you like an orderly homescreen, as Oppos’s launcher doesn’t have an app drawer.


The 13-megapixel rear-mounted camera is one area I’m still undecided on, so will update this review with sample images taken in a range of different conditions.

From my initial testing, shots seem about as you’d expect from a mid-range snapper – solid, if not exceptional, in good lighting and increasingly poor the darker the conditions become.


There are a whole load of camera modes and post-shot tweaks you can make baked into the OS though, which saves on downloading third-party apps to achieve the same thing.

The camera also responds faster than you might imagine a device lacking laser-autofocus might – Oppo says it takes just 0.1 of a second, but I’ll have to take its word for that precise a measurement.

Two areas I found particularly disappointing are the battery life and the single speaker’s sound quality, which isn’t helped by how easy it is to cover up on the end of the phone.


It might seem churlish to complain about a compromised on speaker output on a device as reasonably priced and slim as this. Concessions have to be made somewhere – and better here than in the display – but as someone who listens to a lot of podcasts (with and without headphones) and carries out calls on speaker phone, I’d have liked a little more. It’s not the quietest by any means, but it’s definitely on the tinny side of things, making it largely unsuitable for any kind of reasonable music experience. Unless you happen to like tinny music, of course.

The 3,070mAh battery is a bit of a quandry for me. As a heavy user, it wasn’t quite enough to comfortably get me through a particularly active day. An hour or so of using it as a sat-nav paired with a few hours listening to music and podcasts via Bluetooth headphones will leave you dangerously low later in the day if you don’t use one of the many power-saving modes.

This wasn't a particularly high usage day.
This wasn’t a particularly high usage day.

On the plus side, the R7s supports a fast-charging mode provided you use the original charger and cable provided. This lets you replenish 90 percent of the battery in just 50 minutes charging. That’s great, but at the point where my phone switches off because I haven’t been able to get to a charger all day, that’s less useful.

Oppo’s problem

Oppo’s R7s has a lot going in its favor. It’s slim, light and bestows a slightly more premium feeling than its price tag would suggest, due largely to its all metal chassis.

It even runs a custom version of Android in an attempt to stand out from the pack, but unfortunately it’s made sacrifices that leave me wondering exactly who is going to walk into a shop (virtual or actual) and spend $400 on the Oppo. Granted, some of its direct rivals have made similar sacrifices (like the lack of a fingerprint sensor, for example) but if you’re mostly getting the same hardware anyway, I’m again wondering who, outside of its home markets, will be opting for the Oppo.

It’s great value, though strongly challenged in the specs department by the considerably less slimline OnePlus 2, and if great value is enough to sell a phone, these will be flying off the shelves.

Unfortunately, with much of the smartphone market now hinging around ‘bang for your buck’, it’s a message that Oppo will have to shout louder than all of its larger rivals if it wants the R7s to be a hit in the US and Europe.

Ultimately, the Oppo R7s offers an interesting take on Android that will probably suit power users, albeit not ones that require a removable battery in a device, paired with svelte (if not unique) design cues, and that’s all less than $400.

It’s not the obvious choice, but it’s certainly not a bad one either, provided you can live with the distinctly average battery life.
