The packaging box of Cubot X12

The package is a cardboard box, with printed specs on the back side. The smartphone comes with the back case, and a screen protector is also provided for more protection. We also found a quick start guide in both English and Chinese, supplied by the manufacturer, to help you find your way with this model.  A standard Micro USB cable and a power adapter complete the package contents.

Cubot X12 is entirely made of plastic, but there isn’t any squeaking present. The back side is quite elegant and provides an excellent grip. It seems like the manufacturer used a particular kind of brushing technology since the back side resembles on a metal case at the first look.

We can say that this model doesn’t belong to the group of lighter phones, since the weight is 143 g and the dimensions are 143.8 x 71.1 x 8.1mm.

You can choose from three different colors, which are white, black and gold, to match your preferences.

On the top of the device, we can see an ambient light sensor positioned in the left corner. That is a cool asset, considering that this is one of the cheaper models. The front camera is situated in the top mid section, perfect for capturing your memorable moments.

A Micro USB port is found on the top side, along with the audio jack for your headphones. The most interesting feature that the Cubot X12 packs is the built-in Infrared Remote Control System, for controlling home appliances. All you need to do is to download the app, and you are ready to go.

Three standard capacitive buttons are placed at the bottom, which are the menu, home, and back button. That is a standard button placement considering modern smartphones, and nothing new to speak about. The buttons are supported with the backlight to ease up your clicks in the dark.

The power and lock button is situated on the right-hand side, and the volume rocker button for increasing and decreasing the sound is placed on the left-hand side of the phone. Power & Lock button on the right side of the Cubot X12

Dividing the buttons into separate sides proved to be a good solution for better handling the phone.

In the end, we can see the back of the smartphone with the rear camera and LED Flash installed. The bottom of the back side is reserved for a large speaker for a decent audio performance.

The overall conclusion of the design is that this is a quite nice and elegant model, for those who are looking for a good-looking, yet affordable device.


The display is not the best feature of this phone. We are little surprised with the manufacturers choice to pack a 5-inch 960 x 540 OGS IPS screen, since the 720p (HD) panels are minimum nowadays for a proper resolution. The black color is not quite black, more like a shade of dark gray, but other colors are quite nice thanks to the OGS IPS screen.

The low resolution can be a disadvantage for the users because there are many smartphones in the same price range that have a 720p HD screen.  Pixel density is 217 ppi, which is much lower than the Cubot X16 (441 ppi), and we can place this model in the common group of smartphones considering the density of pixels per square inch.

Performance & Storage

The most important characteristic of a smartphone is its performance. If you want to buy a cheaper device to be a decent “workhorse”, you need to lower your expectations when it comes to affordable models.

The CPU of the Cubot X12 features an 64-bit MT6735M Cortex A7 Quad-Core processor with the effective speed of 1.0GHz. Not quite the most powerful chip, but considering a normal level of usage, this model works just fine with no lags and other problems. With only 1GB of RAM, Cubot X12 is not a multitasking monster, and you may not want to choose this model if you are into game-playing.

Mali-720 is installed to raise the graphic performance of this model, but considering all other specs, this still isn’t enough to play big games with no lags.

Performance in gaming is not the best feature of the Cubot X12

You can play 3D games on Cubot X12, but don’t expect latest titles to run smoothly since this is an entry-level model. Internal storage capacity is 8GB, with upgrade possibilities up to 32GB with a microSD card. That should be enough to satisfy an average smartphone user. Performance specs are limited but what you pay is what you get.


As we already showed in the design section, the new Cubot X12 packs a dual camera system with a rear (primary) and a front camera. When it comes to the front camera, 5MP are more than enough to capture your selfies and for video calling.  8MP is at the back of the phone with an LED flash to ensure better picture quality in low light environment. The overall impression of the camera is decent, but you can’t expect amazing photos in low light, even with the LED flash installed.

On the pictures below you can see the camera interface with features like face detection and face beauty.

Operating system (OS)

The new Cubot X12 runs on Android 5.1 Lollipop, and you can download all your favorite apps from Google Play Store. Android 5.1 Lollipop proved to be the best solution nowadays for affordable models since it supports all the latest apps, and lowers the hardware requirements for the normal use.


Considering that this is an affordable entry-level model, one of the highlights is that it supports the latest 4G network. Dual-SIM card system is also incorporated, with two MicroSIM slots which is a plus.


Network type: GSM+WCDMA+FDD-LTE

2G: GSM 850/900/1800/1900MHz

3G: WCDMA 900/2100MHz

4G: FDD-LTE 800/1800/2100/2600MHz

Bluetooth v4.0 is installed, so you can connect with other devices which also have this feature. Another way to connect with other devices is to use a Micro USB cable, and the Wi-Fi.


When it comes to the battery, the new Cubot X12 has a 2.200mAh unit. The battery is removable, and you may think that this is a small capacity, but if you take the hardware specs into consideration, you will realize that this is quite enough. Low hardware specs aren’t that power hungry, and even with some constant usage, the battery can last a whole day without problems.
