Alldocube X1 Review: a Decent 4G Deca Core Tablet


With all the economic devices that crowd the market, a new premium Android tablet is a rare event nowadays. Very few leading brands in the market continue to bring out tablets that run on Android, and many Chinese producers who produce affordable tablets have disappeared in the last 2 years.

The user experience on an Android tablet is unquestionably different to that of an Apple iPad. Even after all these years, there are only a very limited number of applications optimised for tablets in the Google Play Store. As smartphones get bigger and the PC / Tablet hybrid computers get smaller and smaller, the future of Android tablets does not seem to be particularly bright.

Alldocube is one of the few Chinese companies that are still distributing tablets at affordable prices, although it is currently focusing on Windows-based PC / Tablet hybrids. Alldocube’s new X1 tablet has a beautiful design, relatively powerful hardware and complete 4G phone functions. Let’s take a look at it now.

Technical Specifications

Alldocube comes in a beautiful matte black box. Inside the box we find the tablet, a wall charger, a USB Type-C cable, the SIM needle, the user manual and the warranty card.

In the past, Alldocube did not include the wall charger in the tablet box, so we were pleasantly surprised to find the 5V-2A charger there; it’s a pity though, that there isn’t fast-charge technology with it.


The Alldocube X1 has an ultra-thin body with aluminium frame; the unibody metal construction and the matte black finish give the tablet an extremely premium look.

The front is dominated by the 8.4-inch LCD display, with small frames on the left and right sides. The top and bottom edges are, however, a bit larger since the first houses an 8 MP front camera, a headset and a light sensor, while the latter houses a home button that also has a built-in fingerprint reader. The fingerprint reader is fast and also quite accurate in recognition.

The power button and volume button are located on the right side of the tablet, while the top houses a 3.5mm headphone jack.

A USB Type-C port, the SIM slot and a single speaker grille are located on the underside:

Alldocube X1 can contain two SIM cards or a SIM card and a MicroSD card.

We also find the 13MP main camera with LED flash on the back. It’s good to note that the camera does not protrude from the back panel.

The back cover adopts a sanded texture on the aluminium frame, and overall the tablet is solid and durable, with a decidedly premium unibody design.


The Alldocube X1 sports an 8.4-inch “black diamond” LCD display produced by JDI. It has a resolution of 2560 x 1600 and a pixel density of 359 PPI. The display is extremely clear and crystalline, with realistic colors, brilliant whites and deep blacks.

We found the “eye protection” mode very interesting, which greatly improves reading conditions:

The only note regarding the X1 screen is the brightness. Especially on the outside, even after completely raising the brightness level, the X1 display is not very clear.


Alldocube X1 is powered by a MediaTek Helio X20 deca-core processor, which has 2 cores of ARM Cortex-A72, 8 cores of Cortex-A53 and GPU Mali-880MP4. As for memory, we have 4GB of RAM and 64GB of storage, expandable up to 128GB.

Turning now to the performance benchmarks, the multi-core score on Geekbench 4 X1 is 4402, which matches mid-range smartphones and also beats high-end tablets like the Apple iPad Mini 4, which scored 3222 points on the same test.

The X1 uses Android 7.1.1 Nougat, which has been slightly customized by Alldocube.


The Alldocube X1 has an 8MP selfie camera and a 13MP main camera. Both camera are pretty decent in terms of quality and details.

The camera app on the X1 has a nice user interface and many options. You can even take PIP (Picture in Picture) photos using both the front and back cameras at the same time. There is also HDR support, different filters and a few other modes.

In my opinion, the front camera is more important for a tablet, whereas it is not used as the main camera of the smartphone.

The 8-megapixel sensor, F / 2.2, works perfectly here, even if selfies tend to be too crisp, with slightly dull and lifeless colors.


The X1 has all the full functionality of a phone and supports all 4G networks.

Audio on call is good, as with the 4G data reception. That said, we do not recommend anyone use the X1 as a primary phone to make or receive calls: a full-size smartphone is a much cheaper option. As you should expect, there is also dual-band WiFi, Bluetooth 4.0 and GPS.

GSM: 850/900/1800/1900MHz
WCDMA: 2100MHz
TDS: band34/39
FDD: band1/3
TDD: band38/39/40/41


The Alldocube X1 is powered by a 4500mAh battery. In our tests, it seemed like the tablet had an above average battery life, thanks to the energy efficient SoC. For example, watching an HD video for 90 minutes at almost complete brightness only consumed about 15%.

The only thing that annoyed me about the X1 was the charging speed. With the wall charger included in the sales package, it normally takes about 4 hours to fully charge.


It’s reasonably priced, with a high-quality metal unibody design and a beautiful display. And from a performance point of view, it manages daily activities much better than the numerous entry-level tablets that you can find for under 100 euros.

If you’re looking for an Android tablet in 2018 and want a device worth buying, the Alldocube X1 is undoubtedly a good investment. But if you’re willing to spend more and you’re not a huge fan of Android, you’ll be better off with an Apple iPad or one of the many PC / Tablet hybrids.
