Teclast T40 Pro review - Affordable tablet with LTE

Not all Pro. The Teclast T40 Pro is very similar to the Plus model but has a slightly slimmer case, a stronger battery, and a better main camera. It convinces with a good configuration, including LTE, but has also revealed small setbacks in the test.

After the Teclast T40 Plus the Pro model also has to face our verdict. The sister model turned out to be a good everyday companion, but it also showed a few weaknesses. This review clarifies whether these can be eliminated by the T40 Pro.

Case - Tablet with aluminum body

The display-to-surface ratio of the Teclast T40 Pro is not outstanding at 78%, but it allows holding the tablet firmly in the hand due to the slightly wider display edges. It is also not too heavy and has a pleasant feel due to the aluminum unibody. Only the cutout for the antennas is made of plastic.

The tablet responds to twisting attempts with discreet creaking noises, and firm pressure on the panel causes a slight ripple. Nevertheless, the T40 Pro leaves a solid impression and has good build quality.

The card slot is made of plastic and can either accommodate two nano-SIM cards or a mircoSD card instead of the second SIM. There is no special protection against dust and water penetration.

Equipment - Android tablet without DRM certification

The Teclast T40 Pro has a lush configuration. The USB 2.0 port supports OTG, so both external storage drives and peripherals can be connected to the tablet. There is no audio jack, but the USB port can be used via an optional adapter for the audio output. A connected headset also serves as an antenna for the FM receiver.

A notification LED, IR blaster, and NFC are not available. While these factors are acceptable, the lack of DRM certification is more of a pain, since protected content can only be played in SD quality.

microSD card reader

The hybrid slot can accommodate a microSD card as an alternative to a second SIM card. However, the T40 Pro is even a bit slower than the Plus model in the copy test with our reference card Angelbird AV Pro V60. The speed is appealing in the cross-platform disk test, but not always quite constant.

Software - Android 11 and hardly any updates

The Teclast T40 Pro ships with Android 11 and a visually only slightly adjusted user interface. At the time of the test, the security patches are up to date as of February 5, 2022. However, experience shows that the software update cycle is not long-lasting: the sister model T40 Plus got its last one in mid-November. We do not expect an update to Android 12 for this tablet to come out.

Communication and GNSS - Stable WLAN plus 4G in the Teclast T40 Pro

The Teclast T40 Pro supports Wi-Fi 5 (IEEE 802.11 a, b, g, n, ac) and has an average wireless range. In return, the transfer rates to our reference router Asus ROG Rapture GT-AXE11000 are very stable in both directions and within the expected speed range. The LTE module supports all important bands and was inconspicuous in the test.

A special feature of the tablet is the dual-SIM capability. Both SIMs are LTE-capable and can even be used for making calls. Only an integrated SIP account management is missing.

The GNSS module turns out to be a total failure in everyday use. A satellite fix is possible outdoors with a lot of patience, but it sometimes takes several minutes. Furthermore, only single-band GPS is supported: the T40 Pro did not recognize other satellite services.

Therefore, we, unfortunately, cannot provide our usual practical GPS test with the tablet at this point, since the connection was not stable enough for a track recording. Thus, the T40 is not suitable for navigation tasks.

Camera - Solid imaging performance

Selfie with the T40 Pro
Selfie with the T40 Pro

Compared with the Plus model, the Teclast T40 Pro gets more megapixels for the respective camera on both sides of the spec sheet. Pictures taken with the front-facing lens are quite decent as long as the beauty mode is disabled. Although it can be configured individually, it occasionally produces color spots on the face.

The single camera on the back features realistic color reproduction and finds a good balance between details and sharpness. However, the dynamic range is very limited and the camera barely compensates for some backlight. The zoom is quite decent, but it stops at four times magnification. All in all, the Teclast tablet has a comparatively good lens, which is well suited for documentation purposes, but it does not have an auxiliary LED.

The main camera on the back can record videos in Full HD, while the front lens is limited to the smaller 720p resolution, but both of them only support 30 FPS.

Accessories and warranty - T40 Pro comes with USB-C power adapter

The Teclast T40 Pro comes with a modular power supply (up to 18 watts), a USB Type-C cable, a small tool for the card slot, and an additional screen protector.

The manufacturer offers a twelve-month warranty, which does not affect the retailer's warranty.

Input devices and operation - No fingerprint scanner

The capacitive touchscreen of the Teclast T40 Pro recognizes up to ten simultaneous touches and has a screen protector out of the box. Inputs are implemented precisely and quite quickly, and the gliding properties are also decent.

Google's GBoard is preinstalled as the standard keyboard, but it can be replaced with any layout from the Play Store. A blinking light for incoming notifications is also found in the settings, but there is no corresponding LED - at least, we could not find it.

The T40 Pro does not have a fingerprint scanner but offers two-dimensional face recognition via the front-facing camera instead. This is not very secure, but it works quite well in everyday use.

Display - Darker IPS and brightness sensor in the T40 Pro

Subpixel structure
Subpixel structure

The manufacturer gives different information about the display diagonal of the Teclast T40 Pro. The website says 10.4 inches, but the spec sheet says 10.36 inches - we measured 10.26 inches (26.05 cm) on our test sample. The resolution provides a good pixel density and the uniformity of the illumination is good.

In contrast to the T40 Plus the Pro model has an ambient light sensor, which is a bit sluggish in the test, but masters its task satisfactorily. However, we were a bit surprised that the brightness of the Teclast T40 Pro is lower than that of its sister model. At least it is on the same level in all measurement scenarios, regardless of whether it is a pure white background, an APL50 measurement, or one without an activated brightness sensor.

The IPS panel does not use pulse width modulation, but a high-frequency flickering is measurable below a display brightness of 81%.

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 detected 24180 Hz ≤ 81 % brightness setting

The display backlight flickers at 24180 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 81 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 24180 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 21792 (minimum: 5 - maximum: 3846000) Hz was measured.

Measurement series with fixed zoom level (Rigol MSO5102, 0.5 ms, 100 mV, from left): minimum, 25 %, 50 %, 75 % and maximum panel luminosity

The black value of 0.48 cd/m² enables the Teclast T40 Pro to achieve a decent contrast ratio.

The panel's color reproduction is very cool. Those who like more natural colors can adjust this a bit in the settings, but the tablet does not achieve an optimal color reproduction. Anyway, it is quite pleasing in everyday use, with a slight tendency to oversaturation.

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
18.12 ms ... rise ↗ and fall ↘ combined↗ 6.031 ms rise
↘ 12.09 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 28 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (23.3 ms).
       Response Time 50% Grey to 80% Grey
42.82 ms ... rise ↗ and fall ↘ combined↗ 18.04 ms rise
↘ 24.78 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.692 (minimum) to 636 (maximum) ms. » 62 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (36.8 ms).

Outdoors, the T40 Pro leaves us with mixed feelings. The screen's reduced maximum brightness ensures that hardly anything can be seen in direct sunlight. If reflections are added, the only option is to search for a shadier spot.

The viewing angle stability of the IPS panel is good. There are no color inversions even at very flat viewing angles. At most, the brightness drops a bit and a slight glow effect is noticed in large black areas.

Performance - Exotic SoC in the Teclast T40 Pro

The Teclast T40 Pro is powered by a UNISOC T618 with 8 GB of RAM, which also includes an internal graphics unit ARM Mali-G52 MP2 graphics unit. The tablet delivers a good system performance in the benchmarks and is on the same level as the nominally stronger Lenovo Tab P11 Plus. Nevertheless, minor stutters can be noticed from time to time in everyday use, especially when several apps are displayed next to each other.

The GPU is positioned in the mid-range and provides enough performance for casual games. More demanding games often do not have more than 30 FPS despite reduced detail levels. Depending on the game, the high panel resolution can cause some stutters.

The capacity of built-in memory is huge, but it's not particularly fast. However, it is on par with another eMMC flash in terms of speed.

Loudspeaker

The Teclast T40 Pro offers two speakers on each long edge, which is why the sound can be heard well in every position. The sound output can be extremely loud and even the low ranges are audibly reproduced. Unfortunately, it already sounds quite hollow at medium volumes and the sound distorts heavily when it gets even louder.

An audio jack is not available, but wired audio output is possible via USB-C. Wireless playback is uncomplicated via Bluetooth (supported codecs: SBC, AAC, aptX, aptX HD, LDAC).

Power Management - T40 Pro convinces with long runtimes

Power Consumption

The higher power consumption of the T40 Pro compared to the Plus model is somewhat surprising. Nevertheless, it is more frugal than the Galaxy Tab A8.

The included power adapter fully recharges the tablet within about four and a half hours.

Battery Life

The Teclast's battery runtimes are very good in our practical Wi-Fi test with adjusted display brightness (150 cd/m²) and the tablet lasts for over 13 hours.

The runtime gain is not too lush compared to the Plus model, but clear advantage over the Samsung tablet becomes apparent.

Pros

+ long battery runtimes
+ lots of memory
+ good connectivity including telephony option

Cons

- unusable tracking
- no DRM certification
- insecure update supply

Verdict - Good tablet with LTE for everyday use

In review: Teclast T40 Pro. Test device provided by Teclast.
In review: Teclast T40 Pro. Test device provided by Teclast.

The Teclast T40 Pro feels more expensive than the T40 Plus, especially due to its aluminum unibody. The display is not perfectly calibrated, but it is completely sufficient for everyday tasks and the decent system speed underlines these ambitions. With the integrated LTE modem, the user can be independent of the domestic WLAN and the tablet also convinced with long battery runtimes.

Teclast nominally offers a good overall package with the T40 Pro, but the insecure update policy and the lack of DRM certification can be exclusion criteria

While we criticized the missing ambient light sensor in the T40 Plus, it is now available in the Pro tablet. However, this affects the maximum brightness because the panel became darker. We would have preferred to do without the sensor-based control.

An FM receiver is a very useful accessory, but a suitable audio jack adapter would certainly have been useful in the scope of delivery. The tablet has to put up with criticism in terms of GPS navigation, which was practically unusable in the test. A satellite fix takes forever and is not very stable.

Strong alternatives are the Lenovo Tab P11 Plus and the Samsung Galaxy Tab A8 (2022) however, they cost a bit more or offer a lower performance range.

Price and availability

The Teclast T40 Pro is available among others at Amazon and AliExpress offered. The manufacturer does not have its own store, but also links to other retailers.
