Cubot is not very popular among other Chinese brands, but it has a few models worthy to pay more attention to. A couple of them have been already reviewed by us. Those handsets are the Cubot Manito and Cubot Max. But if the latter is a phablet priced identical to other devices from the same niche, the former one is known for its cheap price. However, today we are going to take a closer look at another handset from this category, the Cubot Rainbow 2. It is the worthy successor to the original model, but this time it has a selling point that can make this phone a bestseller. This is the cheapest dual-camera smartphone in the globe. But if you still wonder why the Cubot Rainbow 2 has caught our eyes, let’s do puzzles.

The phone comes in a well-designed but minimalist box. The front side doesn’t carry any information but the brand name. So you will never know what a handset it belongs to until you take a look at the side. Though it’s made a cardboard of a good quality, I think it’s universal and we’ll see this packaging for other Cubot devices as well.

Once the box is opened we can see the phone itself that already is in a silicone bumper as well as the protective film is attached to it. Though it’ pretty nice to see such additional accessories included in the box, I guess many users will remove them.

There is also a user manual in English, though.

We can find a USB charger (EU).

… and a cable (USB and microUSB). Its length is about 1m, and it’s made of a high-quality material.


Seems we are dealing with a cheap smartphone and the manufacturer should ignore the appearance. Fortunately, it’s not so. The Cubot Rainbow 2 comes with an attractive design showing the designers have worked a lot. The corners are rounded for better ergonomics. So you will face no inconvenience when holding it for a long time.

Moreover, it sports a 5-inch display, which is considered as a gold size for single-hand operations. Unfortunately, its resolution is only HD (1,280 x 720). This is not a big problem, as the phone actually provides acceptable viewing experience. But it yields a lot in comparison to Full HD models.

The Cubot Rainbow 2 has not denied three traditional buttons – though they are not capacitive, they are still located below the screen and occupy a lot of area. Plus, they have no backlight.

As for the upper part, the speaker, a 5MP camera paired with a LED flash, and a standard set of sensors are placed above the screen.

The removable back panel is made of plastic, but I don’t think it’s a cheap one. But this doesn’t mean our fingerprints won’t be left on it.

The Rainbow 2 is not bulky, but it’s not slim as well. We have no complains concerning the body shape, but we can’t praise it as well.

There are up to 5 color options available for purchase. We got the black version.

Obviously, the selling point of the Cubot Rainbow 2 is the dual-camera placed on the back. It’s ringed like the iPhone 7 Plus. The LED flash is next to them.

The phone comes with a metal frame which carries the hardware as well as front and back panels. Generally, this devices provides a good design. Looking at it from the side this opinion is confirmed, for sure.

Two speakers are located on the bottom.

The volume rocker and the unlock button are on the rights side.

The audio jack and a micro USB port are on the top.

The left side is blank. As the back panel is removable, the SIM card slot as well as the memory expansion card slot are placed under the panel.

However, even do not try to remove the battery. It’s not removable.

Camera and Performance

Sporting a dual-camera still doesn’t mean to provide good shooting experience. So we decided to compare the samples with the ones taken by the Huawei Mate 9. The latter is not the best dual-camera smartphone, as there is the Huawei P10, but it is still capable of providing great photos. All the photos taken via the Cubot Rainbow 2 come with Blur Mode, a special camera feature making those two sensors to take good photos in all conditions.

Honestly, the photos of the Huawei Mate 9 are more realistic and provide more vivid colors, it’s pretty nice to see how a $70-costing smartphone compete with an $800-costing flagship.

As for hardware, the Cubot Rainbow 2 sports a MediaTek MTK 6580 quad-core CPU running at 1.3GHz. Thus this is the case when the chip reflects the price category. Other than that, there is only a 1GB of RAM. This is too annoying, because the lowest line of Android smartphone is 2 GB. The internal storage capacity is only 16GB, but it’s acceptable if taking into account it can be expanded up to 256GB via a microSD card slot. Want a surprise? The Cubot Rainbow 2 runs on Android 7.0.

The phone has been tested, and it showcased 24.000 scored points at AnTuTu.

However, to understand whether it’s good or bad, take a pick at some phones packed with a processor from the same niche, Snapdragon 400 and 410.

The next drawback of this handset is the connectivity. It supports only 3G and 2G. Even the Umi Diamond X supports 4G network.

  • Dual-camera on back
  • Front camera with LED flash
  • Android 7.0
  • Stylish look
  • Price tag
  • Non-4G connectivity
  • Poor memory options
  • Slow chip


Looking at the specs list we can immediately understand where the company has saved to come in with a cheap phone. But I guess no one is waiting for a $70-costing phone to sport a high-class SoC, right? So let’s call a spade a spade. This is the cheapest dual-camera smartphone in the world. And this is the only key feature of it. So if you have been looking for a dual-camera handset at a low price tag, it’s the best option to choose from. But it’s not a flagship.
