Bluboo S8 Smartphone Review

1/6th the price, 1/6th the performance. Bluboo is capitalizing on the Galaxy S8 craze with its own copycat version for $150 USD. The Bluboo S8 would have been quite impressive if it weren't for some deep faults.

Along with the Leagoo S8, the Bluboo S8 is riding behind the popularity of the Samsung Galaxy S8 with design features that mimic the South Korean flagship. There's no denying that the Bluboo model borrows heavily from the Samsung model and its name certainly makes no attempt to hide it.

The Bluboo S8 can currently be had for less than $150 USD as opposed to the the $700+ USD Galaxy S8. While they may look somewhat similar, there are a hosts of differences and cut corners on the Bluboo model that we will go over in this review page.

Case

The Bluboo is surprisingly dense and firm for the price. Despite being very nearly the same size as the proper Galaxy S8, it is about 30 percent heavier than the Samsung for a weighty first impression. Bluboo has crafted its version of the S8 to be smooth and round at every corner with no sharp edges to be as visually similar to the Samsung as possible even if its plastic materials are far inferior.

Quality is solid as well. Applying pressure on the plastic back results in no depressions and attempting to twist the unit will cause just slight creaking. There are some very small imperfections on our unit as the gaps between the blue back plate and chrome edges are not uniform and there is a grain-sized dent on the chrome edge near the volume rocker on our specific unit.

Connectivity

Conspicuously missing from the smartphone is a 3.5 mm audio jack. Typically, the audio jack may be omitted due to thickness limitations like on the Moto Z, but even the Galaxy S8 ships with a standard audio jack despite it being slightly thinner than the Bluboo model.

Wireless features include Bluetooth 4.0 and up to 802.11n connectivity. There are no IR, NFC, or Wi-Fi calling options.

Communication and GPS

WLAN functions without any issues when connected to our Linksys EA8500 test router. Average transfer rate sits at around 47 Mbps as expected from an 802.11n radio limited to 54 Mbps. GPS also appears to work as intended when running GPS Test, but it is unusable on the road due to no 3G/4G compatibility with major US carriers.

Telephone and Call Quality

Dual nano-SIM slots w/ MicroSD
Dual nano-SIM slots w/ MicroSD

The telephone software on our test unit appears to be buggy. Making calls is impossible as we would receive the error message "InCallUI has stopped" when attempting to place or receive calls and are unable to test call quality as a result. Our Bluboo software was at its latest version at the time of testing (v2.0.040).

As usual, North American users should make note that the Bluboo S8 was designed for Asian and European carriers. The smartphone lacks compatibility with most 3G and 4G networks in the United States. In theory, however, users should still be able to make calls.

Camera Quality

The rear 13 MP camera produces muddy pictures that are slightly overexposed with lost details in clouds and leaves. Colors have a green hue to them as is common on very cheap smartphone cameras. Noise is far too prevalent for indoor pictures.

Videos record at up to 1080p30. Quality is acceptable when outdoors under bright light, but is far too blurry when indoors.

Input Devices and Operation

Touchscreen

The capacitive touchscreen can recognize up to five fingers at once whereas most other Android smartphones have 10-point screens. In practice, this has little significance for day-to-day use as very few apps take advantage of more than 4-point or 5-point touch features.

Touch-typing is responsive without any uneven input delays if typing very quickly. The 18:9 form factor, however, makes the keyboard feel more cramped than usual due to the narrower design. Simple actions like scrolling and pinch-to-zoom are registered reliably albeit with more frame skips and animation latency compared to mainstream smartphones with more refined software and nimble processors.

The rear fingerprint reader is unreliable. Multiple tries are required almost every time. The unlocking process is very fast for those rare moments where the fingerprint reader unlocks on the first attempt.

Lastly, the vibration feedback is both weak and loud on our unit. It seems as if the vibration is clattering some components inside of the phone to produce an abnormal sound that is very different from most other smartphones we've tested.

The Bluboo S8 display attempts to mimic the round 18:9 displays of the latest flagships including the Galaxy S8, Galaxy Note 8, and LG V30.  Picture quality is better than what one would expect in this price range with its respectable contrast ratio of 812:1 and a very bright backlight that's surprisingly almost as bright as on the Galaxy S8.

Nonetheless, a number of core drawbacks separate the Bluboo S8 display from its pricier alternatives. Firstly, the IPS panel is under a thicker layer of outer glass when compared to the Galaxy S8 and colors do not pop as much as a result. Secondly, response times are much slower than on many other cheap competitors for more noticeable ghosting when scrolling or gaming. Thirdly, colors are nowhere near as accurate as on the Galaxy S8 with higher DeltaE values and color deviation as expected on a budget smartphone. And lastly, the 1440 x 720 native resolution is less than half of the Galaxy S8 and Asus Zenfone AR for a comparatively grainier experience.

* ... smaller is better

Calman measurements reveal inaccurate grayscale and colors, an overly cool color temperature, and poor RGB balance. Thus, while contrast is good, picture quality is nowhere near as good as pricier alternatives since most everything else about the Bluboo display is subpar.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
34.4 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 90 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.8 ms).

This means that the measured response time is worse than the average of all tested devices (39.5 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected ≤ 100 % brightness setting

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9331 (minimum: 43 - maximum: 142900) Hz was measured.

Ourdoor visibility is better than expected and not unlike on the Galaxy S8 since the backlight is almost as bright. Onscreen content remains easy to read if working under shade. Glare is still present, but it's kept to a minimum thanks to the strong backlight and above-average contrast. Direct sunlight will still overpower the display and cause washed out colors.

Performance

The octa-core MediaTek MT6750 SoC is commonly found on very low-end Android smartphones including the Leagoo Kiicaa Mix, LG K10, and the recent Doogee BL5000. According to Geekbench, multi-core performance is slower than even the budget Snapdragon 430 and comparable to the nearly five-year old Tegra 4. It is at least 3 to 5 times slower than the Exynos 8895 in the Galaxy S8 in terms of raw benchmark performance.

The 3 GB of system RAM is a healthy amount considering the price of the device. Still, we wouldn't mind giving up 1 GB of RAM if it had meant a much faster processor for swifter general operation.

Storage Devices

The 32 GB SSD returns average sequential transfer rates according to AndroBench. Sequential write rate, while still slow, is at least faster than on the latest Galaxy J7. Smartphones with UFS storage will easily run laps around the eMMC storage of the Bluboo S8.

Gaming

3DMark Ice Storm scores are similar to the Qualcomm Adreno 505 as found on budget phones like the LG Q6, Nokia 5, and Xiaomi Redmi 4X. Asphalt 8 runs smoothly on the Bluboo S8 as well as 720p Youtube videos to fit the native resolution of the display. Local 1080p H.264 video files play without noticeable frame skips even if the picture quality is not as crisp as we would like.

Temperature

Surface temperatures are generally flat when idling on both sides of the device. Like most smartphones, the top half will become warmer after extended use since the battery occupies nearly the entire bottom half. The area closest to the MediaTek SoC can become as warm as 42 C compared to just 37 C on the Galaxy S8. Fortunately, the Bluboo never becomes uncomfortably warm during browsing loads.

Speakers

The speakerphone is lacking in bass and overemphasizes treble as shown by our pink graph below. Sound quality is tinny as a result and volume could have been louder for outdoor use. The phone does not rattle if on higher volume settings.

Strangely, the speaker exhibits recurring static noises from time to time even when on mute. It's very low in volume, but the mere presence of static suggests imperfect wiring or interference surrounding the speaker.

Power Consumption

The Bluboo smartphone is not as efficient as a handful of other 5.5-inch and 5.7-inch alternatives including the Huawei Y7. When idling, the Bluboo will draw anywhere from 1.5 W to 2.5 W compared to roughly 0.5 W to 1.5 W on the Huawei Y7 or Samsung Galaxy S8. Perhaps unexpectedly, the Bluboo S8 is more demanding than the Galaxy S8 when under similar average loads. The poorer efficiency of the Bluboo model is in line with its shorter runtimes as well as shown in our next section.

Power consumption values for maximum load is lower than average load possibly due to throttling of the SoC when subjected to Stability Test stress.

Battery Life

The non-removable 3450 mAh battery is larger in capacity than the 3000 mAh battery in the proper Galaxy S8. Even after taking into the account the slower MediaTek processor in the Bluboo S8, battery life is still significantly shorter than on the Samsung flagship. Constant WLAN use will last about 6.5 hours on the Bluboo smartphone compared to almost 12 hours on the Samsung under similar brightness settings and conditions.

Verdict

In review: Bluboo S8. Test unit provided by Bluboo
In review: Bluboo S8. Test unit provided by Bluboo

The Bluboo S8 looks great, feels good to hold, and has a surprisingly bright 18:9 display. Everything else is simply lukewarm at best or not even functional at worst.

For starters, North American users should be aware that the Bluboo S8 does not carry the necessary 3G or 4G radios for compatibility with major providers. Second, the telephone app would crash on our unit even after updating to the latest software version. Vibration is weak, colors are off, the fingerprint reader takes several tries, camera quality is grainy, there is static from the speaker seemingly at random intervals, and the lack of an audio jack feels insulting especially when the core basics are such a failure. Perhaps we simply received a faulty unit, but at the same time, this certainly reflects poorly upon Bluboo's quality assurance standards and longevity of the device.

A Galaxy S8 clone on the surface, but an ultra-budget phone within. We don't expect much from a smartphone for under $150 USD except for functional basics, but the Bluboo S8 can't even get calling or speakerphone to work reliably.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
