Another great thing here are the dual rear cameras, these cameras are located in the best spot possible on the corner of its back panel, making the overall look of this smartphone even better.

The Cubot Rainbow 2 is equipped with an IPS display with GFF technology making it look transparent. It comes with a 5.0’inch 2.5D curved glass screen with 1280x720p HD resolutions, its PPI density is around 294 pixels per inch, which means that the colors are well saturated with sharp and colorful viewing experience.

Smartphones with low price tags generally come with an average display but Cubot has certainly worked on the display of this device making it better and more beautiful.


This Cubot manufactured device is packed with a MediaTek MT6580A SoC supporting it is a 32-bit QUAD CORE ARM Cortex-A7 CPU and ARM Mali-400 MP2 GPU with 1 GB RAM and 16 GB of internal storage capacity.

The RAM management here is little weak due to it’s not so big 1GB RAM making it a bit slower than most of the smartphones but let me tell you that it’s still worth every penny you spend here because at this price tag you will never get something Cubot is offering right now.


The main and most noticeable feature of Cubot Rainbow 2 is its dual lens rear camera which allows us to take pictures at our will with the amount of focus we want to use giving it immense bookeh to enhance and highlight the object we want our viewers to focus on.

The primary rear camera found here is a CMOS 13.0 MP shooter whose job is to take fast and beautiful pictures and a secondary rear camera of 2.0 MP is used for measuring the depth of the field while taking pictures. These combined create some impressive results and you will surely love to see them.

On the front, we have a 5.0 MP shooter with some handy built-in features like Intelligent Beauty and a 50mA soft LED flash which will brighten your pictures even in low lighting conditions.


android 7.0 Nought in CUBOT RAINBOW 2

This device comes with the most advanced operating system of this generation the Android 7.0 Nougat out of the box which makes it even more exclusive because there are not many smartphones who are featuring android Nougat out of the box like Cubot Rainbow 2.

Android 7.0 is equipped with advanced graphics processing system called Vulkan which can have reduced CPU occupation at the same time it owns JIT complier which makes installation 75 % faster and the occupied space is also reduced by 50% which is amazing.


The Cubot Rainbow 2 comes with a built-in 2350mAh Li-ion powered removable battery which does sound less but looking at the RAM consumption and a 720p display output we think that this amount of battery power will be enough for this device to last for a day.

Few More Noticeable Features:

Dual Card Slot in Rainbow 2

  • Dual card Dual Standby

The Cubot Rainbow can support two SIM cards at the same time which is good for traveling or any type of business journey abroad. It also supports upto256GB of external storage through a dedicated MSD card slot

  • High-Speed Wi-Fi and Bluetooth 4.0:

Cubot Rainbow 2 comes with built-in high-speed Wi-Fi & Bluetooth module 4.0, which makes this phones data transmission faster and more stabilised.

Bottom Line:

After reviewing the Cubot Rainbow 2 we can say that this is overall a great piece of technology mainly because of its very low price ~$80, mostly so at this price range a phone featuring a dual lens camera is something every consumer wants. Although it is basically for normal day to day usage and for this phone will perform very well for this purpose but heavy usage is not something you will get out of Cubot Rainbow 2.
