Blu is back with another Android handset for U.S. consumers who prefer the unlocked life. The Blu R1 Plus packs a big screen and an even bigger battery. You can opt to use the phone on AT&T or T-Mobile, with support for up to two phone numbers thanks to dual SIM card slots. If you're in the market for a network-flexible smartphone, the R1 Plus handles the basics. Here is Phone Scoop's in-depth review.


Is It Your Type?

Blu sells inexpensive, unlocked smartphones directly to consumers, generally via online outlets such as Amazon.com. The R1 Plus is a bigger, badder version of the R1 HD thanks to a larger display and higher capacity battery. If you're in the market for an unlocked Android handset with a big screen, the R1 Plus is one of many options.


Blu is in a bit of a design rut. Nearly every phone the company has announced in recent months bears a similar (nee, identical) appearance. The front features 2.5D curved glass, while the rear panel is defined by a gray metal plate, gray plastic end caps, and chrome accents. It's a fine look, but Blu is quickly losing any sense of individuality with this recycled design language.

A large slab of black glass forms the R1 Plus' front surface. The glass is curved very slightly along all four edges, which helps the in-hand feel. The rear of the phone is maybe 80% metal and 20% plastic. Chrome accents run from side-to-side across the top and bottom edges and separate the metal portion of the rear panel from the plastic ends. The gray of the metal is mismatched when compared to the gray of the plastic, but this seems to be a theme on Blu's phones. Like many contemporary Blu handsets, the R1 Plus has a conservative appearance that could almost be called classy.


The 5.5-inch screen necessitates a rather large footprint. The thick bezels don't help. The R1 Plus is a big phone, there's no other way to describe it. It's more than 6 inches tall, more than 3 inches wide, and a whopping 0.43 inches (10.5mm) thick. Blu did curve the rear panel where it reaches the side edges and this helps push the phone into your palm a bit. People with smaller hands may not be comfortable using the R1 Plus. It's often a two-handed device. The size, thickness, and the weight make it the R1 Plus a brick in your pocket. It'll fit in your pants, but you'll always know it's there.

Materials are on par with other Blu phones, but fall short of similarly-priced handsets from Samsung, LG, Motorola and others. The glass front feels fine and is firmly mounted to a thin plastic frame. I'm not in love with the way Blu glued the rear panels to the outer plastic frame. Like many Blu phones, the chrome bands are grooved and have sharp edges to them that cut against your skin. The materials may not be the best ever, but the R1 Plus does appear to be assembled tightly and all the seams are tight.

I always like to see a solid, seamless piece of black glass on phones. The display and bezels disappear into one another with the screen is off. It's quite easy to pick out the user-facing LED flash and user-facing camera. Blu opted for on-screen buttons to interact with the Android operating system, so the only other visible design element on the phone's face is the chrome Blu logo, which is painted along the chin.

The screen lock key and volume toggle are on the right. The screen lock button is more of a nub and measures only a couple millimeters in length. Thankfully it has a ribbed textured to it and a sharp profile. The volume toggle is rather thin, but its length helps a lot. The buttons are a cinch to find without looking. Travel and feedback is good. The 3.5mm headphone jack is on top and the microUSB port is on the bottom.

I do like the shape of the R1's rear panel. Like many other Blu handsets, the R1 is at its thickest along the central vertical axis and it tapers towards the sides.

Some may be pleased to learn the entire rear panel lifts off. Removing the panel provides access to the SIM and microSD memory card slots underneath. Clasps hold the panel on pretty tightly and it takes some effort to pry loose. The R1 Pls supports two micro (3FF) SIM cards. (That's odd, as the newer nano (4FF) size is now more common.) The R1 Plus' battery is concealed within the phone's chassis and cannot be removed.

There's no fingerprint reader. The phone isn't waterproof.

I've grown weary of Blu's tired-and-blue design aesthetic. Maybe I'm being too hard on the company, but the R1 HD is nearly indistinguishable from a half dozen other Blu handsets. Toss in the platter-like dimensions and below-par materials and you have an uninspired smartphone in your hands.


A 5.5-inch display is hiding beneath the massive glass plate on the R1 Plus's face. It offers only 720p HD resolution, which is a bit light in the pixel department. During my tests, I found the screen to be adequate for everyday activities, including email, social networking, gaming, and music listening. You can still enjoy YouTube and other standard video content on the large canvas, but the R1 is no VR machine. The 720p resolution provides just enough to keep the on-screen elements looking smooth and free of pixelated edges.

The LCD panel is quite bright. I had no trouble using the phone indoors and out, but the screen's auto-brightness tool wasn't quite up to the task. You'll likely have to manage brightness manually when stepping outdoors. Viewing angles are pretty good, as I noticed only minimal brightness loss when tilting the phone side to side.

The R1 has a decent screen for the price point.


The Blu R1 Plus may support two SIM cards, but its LTE support is rather weak. It covers Bands 2, 4, 7, 12, and 17, which makes it compatible with the core LTE frequencies of AT&T and T-Mobile, but leaves it lacking some of the newer bands. I took the R1 Plus for a run on both AT&T and T-Mobile's networks and can't say I came away too impressed. The phone performed below average on both networks. In general, it remained attached to LTE 4G, though I saw it drop down to HSPA 3G fairly often in weak coverage areas. Branded carrier phones are more apt to stay on 4G nearly 100% of the time.

The R1 Plus was able to make calls on both networks, but inconsistently. Calls connected on the first dial on AT&T, but often required two attempts on T-Mobile's network. The R1 dropped calls regularly, including at highway speeds. That's no good.

Data speeds were closer to 3G than 4G. The R1 could handle email, social networking, and similar tasks, but streaming media over the network was mired with buffering and frequent pauses. The R1 can connect to AT&T and T-Mobile, but the experience leaves a lot to be desired.


The R1 Plus is acceptable for making phone calls, but not by much. The earpiece delivers enough volume for use in and around your home or office, but it's more or less inaudible anywhere else. I found I needed to keep the volume set up all the way at all times. Voice clarity is middling at best. About half the calls I made were pretty good, but the rest were riddled with nasty distortion. If you're a T-Mobile subscriber, the R1 HD supports VoLTE and HD Voice. Connecting through HD Voice provides a significant boost in call quality. People I spoke to through the R1 Plus said I sounded just okay.

The speakerphone actually pushes out a lot of sound and is mostly free of any distortion. I had no trouble hearing speakerphone calls at home, in the car, or walking around town. Music, ringers, and alerts can all be set to crazy loud volumes. The vibrate alert is quite good.


If there's one killer reason to by the R1 Plus, it's battery life. The 4,000 mAh battery provides two days of life no matter how you use the phone. A week of testing consistently proved the R1 Plus was capable of pushing from breakfast one day to bedtime the next with power to spare.

The only battery-saver tool aboard (which you won't need at all) is the native Android app.

The phone does not support rapid nor wireless charging.

Bluetooth, GPS, NFC, WiFi

The R1 Plus's Bluetooth radio worked okay. Pairing and connecting was generally not a problem. The R1 managed to hold onto my car's hands-free system, but had trouble with a pair of Bluetooth headphones. Calls I made via the hands-free connection were just barely acceptable. Music sounded pretty thin and tinny even when streamed to a really good speaker.

The phone's GPS radio performed as expected. It was able to find me in just a few seconds and resolved my location to within about 25 feet. It didn't exhibit any lag nor speed issues when used as a real-time navigation device.

The R1 Plus doesn't have NFC. The WiFi worked well enough.


Lock Screen

Thanks to the near-stock version of Android running on the R1 Plus, the lock screen experience is simple, if basic.

Press the lock button to wake the screen. You'll see a large digital clock in the middle of the display with notifications lined up sequentially beneath. As expected, you can dial in how much detail is shared by notifications on the lock screen. Dismissing the notifications requires but a swipe. The lock screen allows you to access the Quick Settings shade. There are shortcuts to Google Assistant and the camera in the lower corners of the lock screen.

Security options run the typical, which means PIN, pattern, password are available. It's a shame there's no fingerprint reader.

Home Screens

The R1 Plus runs Android 6.0 Marshmallow. I'd berate Blu heavily for selling a phone in May 2017 with Marshmallow aboard had the company not promised to update the R1 Plus to Android 7 Nougat "soon." (Seriously, though, Nougat has been available to phone makers since September 2016.)

Worse, the phone's security patch level is dated October 2016. That's practically unforgivable.

The mostly stock Android home screen doesn't offer any surprises and is dead simple to use.

Users can rearrange the home screen panels to suit their personal style. The home screens support folders, widgets, animated screen transitions, and so on. The phone has one home screen panel active out of the box and it contains a handful of the phone's preloaded apps. The app drawer, Quick Settings panel, and full settings menu are all stock Android. The Quick Setting panel slides down from the top as expected and the Settings tools are arranged in an easy-to-decipher list.

One thing worth pointing out: because the phone supports two SIM cards, you can customize how incoming calls on the two lines alert the device. For example, you can set one ringtone for your personal number and a different ringtone for your work number.

Home Screen  

The R1 Plus is powered by a 1.3 GHz quad-core MediaTek 6737 processor with the Mali T720 GPU. It ships with 3 GB of RAM and 32 GB of storage. I didn't run into any speed-based issues while testing the phone. The MediaTek processor was able to deliver a smooth experience across the board.


The R1 Plus doesn't have a dedicated camera button, nor are there any trick shortcuts to open the camera. Your best bet is to use the lock screen shortcut. The camera opens quickly enough.

The controls are arranged in a standard format with the shutter buttons on the right side of the screen. There are no controls on the left side of the display. Swipe the viewfinder up to access all the settings and swipe the viewfinder down to access the shooting modes. Swipe either left or right to switch to the selfie camera.

The R1 Plus has 8 different shooting modes: normal, professional, HDR, panorama, night, face beauty, sports, and scene frame. Many of these modes are self explanatory and work as you expect them to.

The “professional” (manual) mode is decent and allows users to adjust focus, exposure (brightness), ISO (speed), white balance, and sharpness. You cannot set your own shutter speed, which means no creative night shots. That's a shame. The smart frame tool is kind of fun. It puts a picture you've taken into a frame, such as a mirror, laptop screen, TV screen, or billboard advertisement. We've seen this on other Blu handsets.

The normal shooting mode, which is the default setting, is perhaps too simple to use. A quick tap of the screen will set focus and exposure, which I appreciate. Since the shutter button is the only visible control, the viewfinder is clean and friendly. Changing most settings requires at least two steps. Though the flash and HDR tool aren't available by default, the good news is you can customize the settings a bit and add up to five settings shortcuts to the main viewfinder. That's helpful. The settings screen itself is an array of icons rather than a boring list, but using the icons to make changes requires lots of pressing and pressing again.

The camera generally performs well. The only real exception is the HDR setting, which is very slow. Further, low light hurts the camera's ability to focus, which also slows things down a bit. In all other modes and environments, however, the R1 Plus's camera is quick.



The R1 Plus has a 13-megapixel sensor that does an acceptable job considering the phone's price point.

Pictures are generally sharp and white balance is mostly accurate. I didn't see any problems there. Exposure tends to be the R1's weak point. It had a really hard time balancing bright/dark spots in some of the outdoor shots I took. Switching on HDR helps a lot, at the cost of shooting speed. Shots taken in low light are often a bit grainy. The flash tends to blow out images a bit.

The 5-megapixel selfie cam does alright. It includes a beautification tool for dialing back skin imperfections, but the results can be ghastly if you go too far. The user-facing flash — a rare feature at this price point — will help improve indoor selfies.

The R1 is limited to either 720p or 480p video capture. That's a bit of a bummer. The R1 Plus produced usable results as long as there was plenty of light. Shooting indoors often leads to grainy, soft video.

Most people can probably get away with using the R1 as an everyday camera, but I'd use something better for sightseeing, travel, and important events.



The Blu R1 Plus is a mediocre handset with only a few truly redeeming qualities. If all you want is an unlocked phone with a big screen and killer battery life, then perhaps you'll be happy with the R1 Plus. I generally want more from my phone, which is why I find the R1 Plus hard to recommend.

The 5.5-inch screen offers plenty of viewing space, but the 720p resolution prevents the phone from being the best video tool (and you can forget VR). The R1's compatibility with AT&T and T-Mobile is below average, and I saw dropped calls and slow mobile data speeds. Voice quality is just barely adequate unless you're using HD Voice on T-Mobile. Thank goodness for Blu the R1's huge 4,000 mAh battery lasts for days.

The core Android platform runs fine, but I do have to chide Blu a bit for shipping a phone with Android 6 Marshmallow mere days before Google unveils Android 8, and for its lack of security updates. The camera application works well, though I think tweaking the layout a bit could help. The phone captures average photos at best.

The R1 Plus from Blu costs $160 and is available from Amazon and BestBuy. If you're in the market for a simple, unlocked Android handset with support for two SIM cards, then this device might make sense for you. Most everyone else will benefit by sticking with low-cost handsets from the likes of ZTE, Motorola, and Samsung.
