Bluboo S1 Smartphone: The Xiaomi Mi Mix clone for 135€

Bluboo, like the Doogee Mix, follows the success of the Xiaomi Mi Mix and brings a “borderless” smartphone to the market. With a starting price of 135 €, it is significantly cheaper, but offers, for example, on the processor side more than is usual in this price category. Can also convince the rest of the hardware?

From the front, it looks very similar to the Mi mix, but in contrast to the large model, there is a thin, upper edge and the lower one is bigger, since the fingerprint sensor was placed there. The back could be 1-to-1 from the direct competitor of Doogee and is kept quite “clean”. The 5.5 inch FullHD display (Doogee only uses a 720P display) is protected by Gorilla Glass 4 and is rounded to the left and right. With dimensions of 148.6 x 74.3 x 7.9mm it is slightly smaller than other 5.5 inch smartphones but the same width and at 175g also somewhat heavier but still lighter than the Doogee Mix.

As a processor, the new MediaTek Helio P25 Octa Core is used, whose two ARM Cortex-A53 clusters each clocked with 2.5GHz and 1.6GHz . On the graphics page it is supported by the ARM Mali-T880 MP2 GPU, which offers 1GHz. When working memory 4 or 6 GB of the current LPDDR4X standard is used while the main memory is 64GB or 128GB is large and can be expanded (up to 256GB). It is therefore set to current and better hardware than is usual in this price class. The battery should be with 3.500mAh large enough for the offered hardware and one through the day bring. Nothing is known about a possible PumpExpress quick-release support.

Bluboo S1 design

The rear main cameras release with 13 and 3 megapixels each . Unfortunately, Bluboo speaks here often of 16MP, but these can only be achieved by interpolation . The same also applies to the front camera which has 5MP and interpolated to 8MP. This is also placed in the lower right corner by design.

Connectivity & Tools

LTE Band 20 is supported as well as the other bands important in Germany. The SIM slot is a hybrid in which you have to decide between memory expansion and 2 SIM cards. The current WLAN AC standard is unfortunately not available as well as a headphone jack. To compensate for this, an adapter is included, which converts the USB Type-C connector to the jack. GPS and GLONASS are available for location determination. The current Android 7.0 nougat is used on the software side .

At the end of this month the Bluboo S1 will be available for 135 €. At the beginning, however, the price will be even higher if you want to import it. The competing smartphone from Doogee currently costs comparatively around 160 € but also offers a weaker screen.


The design, if not as amazing as the Mi mix, I find personally very appealing, because “borderless” simply looks good. By the 1080P display it is for me, compared to the Doogee mix, also the better clone , since one at 5,5 inch 720P simply notes. The rest of the hardware (chipset & RAM) is also convincing on the paper by current standards .

Greatest flaw in my opinion is the missing headphone jack and the misleading camera advertising as well as that a sensor has only 3MP , which is very little.

How hard and software then finally work together and what battery life is the result will then show our test as soon as the S1 arrives at us.

What do you think of the Bluboo S1 and what questions do you have?
