The cheapest AMOLED tablet on the market – Acer Iconia X12 tablet review

Can Acer still do Android?

Acer is venturing back into the field of Android tablets. The Iconia X12, which is currently the most expensive Android device in the manufacturer's portfolio, is attracting a lot of attention. For around $500, it comes with an AMOLED screen and a protective cover. Is that enough to compete against the established competition?

Verdict on the Acer Iconia X12

It should technically be a good thing if an established laptop manufacturer such as Acer were to provide more competition in the Android tablet market. Unfortunately, however, Acer hasn't succeeded with its Iconia X12.

The main problem is its price: In the region of around $500, Acer is competing against the Apple iPad 11, which simply plays in a completely different performance league. And the rest of the competition in this price range also offers more performance, faster internet, and in some cases, brighter screens.

The manufacturer has even failed in one of its core disciplines: While Acer boasts good service for its laptops, there is no update promise at all for its Android tablets.

That being said, there are still a few rays of hope: Indeed, an AMOLED display is a rarity in this price class. Even so, the Iconia X12 can only deliver limited brightness and inaccurate color reproduction.

Little things, such as poor detection of accidental touches on its touchscreen in combination with narrow display edges, additionally make life difficult for the tablet.

If prices fall significantly, the Acer Iconia X12 could be worthwhile, as it boasts good battery life. Buyers are also treated to a decent accessories package.

Pros

Case and connectivity – "Flexible" metal case

Acer has packed its tablet into a dark gray metal case, which contains a plastic strip on the upper edge to improve the quality of antenna reception. With a thickness of just 6.7 millimeters, its case is actually pretty slim but otherwise, its dimensions are normal considering its screen size of 12.6 inches. Moreover, its weight of 600 grams is also acceptable.

The corners of its case can be bent quite noticeably and with relatively little effort; a little more stability would have improved its quality impression. It features no protection against water or dust.

Internally, its USB port is only connected according to the USB 2.0 standard. However, users can make use of a 3.5 mm port for analog signal transmission to headphones or speakers.

The tablet is available with either 128 or 256 GB of mass storage, plus 8 GB of RAM. You can expand its storage via a microSD card. The microSD card reader's speed is fine.

There are a surprising number of accessories included with the tablet: a charger, a USB cable and even a protective cover. In some countries, a stylus is included too.

Communication and operation – The Acer tablet without a fingeprint sensor

Unfortunately, the fastest Wi-Fi standard the tablet supports is Wi-Fi 5 and there is only one antenna each in the direction of transmission and reception. As a result, its transfer rates were significantly lower than the comparison devices during our test, measuring in at between 264 and 379 MBit/s.

Its touchscreen only has a frame rate of 60 Hz, which means that inputs are sometimes a little slower than on tablets with faster screens. Its narrow bezels give the tablet a modern look, but they make it easy to make accidental inputs, as happened to us several times during our test: It didn't accurately recognize when we placed the palm of our hand onto the screen by mistake, leading to the touchscreen no longer responding elsewhere.

It doesn't feature a fingerprint sensor, and facial unlocking is also not possible.

Software and sustainability – Unclear updates

The Iconia X12-11 runs Android 14 and it's unclear when and if it will see an update to Android 15. Acer has also said nothing about the update duration that can be expected, only that there should be new versions approximately every six months. Other manufacturers are clearer and faster when it comes to updates.

The installed Android is largely unchanged, so you'll quickly find your way around. Apart from a few games, no third-party apps are pre-installed.

In terms of sustainability, we can hardly give Acer any points either, even though it advertises CO2-neutral production through compensation via a third-party provider. Apart from this, there are plastic films in its packaging, and the manufacturer has provided no information on the CO2 footprint of the product or which materials have been used.

Cameras – Okay for snapshots

Photo taken using front-facing camera

The Acer Iconia X12 has a 13-megapixel camera on the back and takes decent pictures in good lighting conditions. Still, you shouldn't enlarge them too much: Details then often appear blurred and inaccurate.

When taking pictures of our surroundings, the camera coped quite well with the difficult lighting situation with backlighting, although the outlines of the buildings and many details looked blurred here too. In low light, the autofocus struggled and the brightness was only moderate.

Videos can be recorded in a maximum of 1440p, but you can't select more than 30fps. The resulting videos are generally usable, but the autofocus reacts sluggishly from time to time and isn't very precise.

There is an 8-megapixel camera on the front of the tablet, which takes decent selfies, but the photos lack dynamics.

Display – One of the cheapest OLED tablets

The highlight of the Acer Iconia X12-11 is said to be its screen, as it's equipped with an OLED panel. This is usually only found on much more expensive tablets, as such large OLED displays are comparatively dear.

The problem, however, is that Acer has hardly been able to exploit the actual advantages of this technology due to the cost pressure: Its maximum brightness is limited to under 400 cd/m², and since you can't adjust its white balance and the factory settings are only moderately accurate, its color reproduction also isn't the best.

Added to this is the PWM flickering we measured at low brightness levels.

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 121 Hz
Amplitude: 42 %

The display backlight flickers at 121 Hz (worst case, e.g., utilizing PWM) .

The frequency of 121 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8350 (minimum: 5 - maximum: 343500) Hz was measured.

Performance, emissions and battery life – Little power for the price class

Available Bluetooth audio codecs
Available Bluetooth audio codecs

With regards to performance, Acer has gone for the MediaTek Helio G99. This is an unusual choice for this price range, and you can see in the benchmarks that the Iconia X12 couldn't keep up with similarly priced tablets.

During everyday use, the tablet usually runs smoothly and you'll only have to live with occasional stutters. However, it doesn't have many performance reserves for gaming or more complex apps.

The heat build-up on its case after prolonged load is limited locally and is very moderate overall. Plus, the stress tests revealed that its performance barely dropped.

The Acer Iconia X12 has a total of four speakers, which don't have the best sound and are somewhat treble-heavy. If you want to connect wireless audio devices, you get a decent selection of Bluetooth audio codecs.

The tablet can be charged at a maximum of 20 watts. As a result, its 10,000 mAh battery takes up to 4 hours to recharge. However, its runtimes are then quite good, with the device managing up to 13:51 hours during our WLAN test. It's definitely enough for a day's use on the couch.

Acer Iconia X12 review. Test device provided by Acer Germany.

The Acer Iconia X12-11 is currently the cheapest tablet with an OLED display that is widely available.

However, you'll have to accept some limitations, both in terms of its performance and the display itself.

The selection of devices to be reviewed is made by our editorial team. The test sample was provided to the author as a loan by the manufacturer or retailer for the purpose of this review. The lender had no influence on this review, nor did the manufacturer receive a copy of this review before publication. There was no obligation to publish this review. We never accept compensation or payment in return for our reviews. As an independent media company, Notebookcheck is not subjected to the authority of manufacturers, retailers or publishers.

This is how Notebookcheck is testing

Every year, Notebookcheck independently reviews hundreds of laptops and smartphones using standardized procedures to ensure that all results are comparable. We have continuously developed our test methods for around 20 years and set industry standards in the process. In our test labs, high-quality measuring equipment is utilized by experienced technicians and editors. These tests involve a multi-stage validation process. Our complex rating system is based on hundreds of well-founded measurements and benchmarks, which maintains objectivity. Further information on our test methods can be found here.
