However, you cannot use any cards that are formatted as exFAT, since the system does not recognize them. You also cannot move apps onto the storage cards. Thanks to the 3. On the other hand, there is an infrared blaster on the top edge, which you can use to control your TV, for example. With Bluetooth 5. The smartphone is even part of the Android-One program, which guarantees software updates for the next few years. Android 9 is preinstalled, and at the time of our testing, the security patches are on the level of August and thus current.

Besides the Mi Community app and the Mi Store app, Xiaomi did not install any additional apps, which should please the purists. On the other hand, you also have to make do without some features compared to MIUI, such as the Game Speed Booster or Dark Mode, which is finally supposed to also come to vanilla Android in Android The Xiaomi Mi A3 supports Wi-Fi 5, which means that you have to make do without the more current and faster But this is normal in this price range and even above. The WLAN signal is not as stable as we would have hoped for.

However, the European model lacks some frequencies that are necessary in the USA, so depending on your location and the provider, you could encounter some difficulties with your reception there. Within the city and its surroundings, the reception is also decent indoors, but it is noticeably better outdoors. Indoors, it takes quite a long time until we can finally get a GPS signal near the window, where the device can determine our location with an accuracy of up to 21 meters.

Outdoors, the accuracy of the locating quickly increases up to four meters. In Google Maps, the smartphone is also able to locate us with reasonable accuracy. The compass also works well, showing our viewing direction fairly accurately. For our practical test, we are also taking the Garmin Edge professional navigation device for bikes with us for comparison. The Xiaomi Mi A3 does not fare badly here. While it cuts some corners from time to time, most of the time it handles even the narrow roads in the old city fairly accurately. There are some small deviations, but those who don't depend on absolute precision for every second of their trip will be served well by the Xiaomi Mi A3 in everyday navigation.

Following the purist paradigm of Android One, the standard app from Google is used as the Telephone app. It is clearly arranged and offers the option to view favorites when opening the app. In addition, this area also shows frequently contacted numbers automatically. Tabs allow you to access the recent calls or contacts lists. The voice quality is acceptable.

While your conversation partner can be understood easily, the voice is not completely clear and also slightly distorted at high volumes. Our voice is also transferred not completely clearly but is still understandable. Using the speaker and hands-free microphone, we can also hear our conversation partner well, but the voice is not as present as when using a really good telephone, and our voice is transferred sounding slightly hollow here.

Again and again, the voice of our conversation partner is interrupted or our own voice isn't transferred to the conversation partner. Xiaomi should deliver an update patch for this quickly. We did not have any trouble making regular phone calls using the mobile network. There are quite significant changes in the cameras. While it had been two lenses in the back of the predecessor, there are now three, with the third lens not taking separate recordings but offering additional information on the depth sharpness.

With 48 megapixels, the main camera has a fairly high resolution. However, four pixels are combined into one by default, in order to increase the captured brightness. This results in megapixel recordings, which is completely sufficient for everyday pictures in most cases. But if you need them, you can also record megapixel images. An additional wide-angle lens offers a larger viewing angle and smooth zooming up to the 0.

Generally, the main camera takes fairly good pictures that are rich in detail. The white balance tends strongly towards blue. The brightness could be better, for example in the scene of the surroundings. The same problem can be seen when looking at the low-light recording: You can hardly recognize any detail in the teddy bear or the figure on the right. So the camera is rather badly equipped for dark situations.

With the video function, you can record movies with a resolution of up to 4K and at 30 FPS. Darker areas can quickly result in some visible graininess, and the adjustment of the exposure is not smooth but occurs in some slight steps. However, the color reproduction and sharpness are okay here, so that you can record your own videos with the MI A3. The sound recording also works without any problems. At 32 megapixels, the resolution of the front camera is ample, but the brightness could also be better here.

If you slightly enlarge the picture, you can see some clear graininess, and the sharpness is rather mediocre in the detail. For snapshots and the occasional selfies, the camera is sufficient, but it does not come near the quality of a really good front camera. By the way, the camera app really comes from Xiaomi, so the manufacturer slightly deviates from pure Android here. It is easy to operate and the necessary adjustments are presented fairly clearly. Those who do not like the app can install numerous camera apps from the Google Store.

One click changes the position on touchscreens. One click on the zoomed-in image opens the original in a new window. The first image shows the scaled photograph of the test device. We also evaluate the camera in controlled light conditions in our test lab. At 1 Lux, the test chart can hardly be recognized and the ColorChecker cannot really be recognized at all anymore. On the other hand, with perfect lighting, we see a quite decent result in terms of the color accuracy.

Particularly yellow and black tones are reproduced quite accurately, but dark color tones create more problems.

Under bright light, the reproduction of the test chart is very sharp and without any visible artifacts in the color areas. In addition to the regular accessories, Xiaomi also adds a silicone bumper case into the box, so that you don't have to buy this separately anymore. Since it is a clear case, you can still see the color reflections in the back of the smartphone.

Officially, Xiaomi still does not offer warranty processing for its customers in all countries. However, you can get a warranty from the vendor 24 months according to warranty laws in Germany, for example. It is easy to operate, offers many setting adjustments, and it can also be displayed with various designs. From time to time, we had some problems with inputs on the right edge of the display not being recognized immediately, but otherwise you can type easily and reliably on the Mi A3.

Overall, the touchscreen responds reliably to our gestures and can be operated without any problems. The fingerprint sensor is below the glass of the display. Since the sensor is positioned fairly close to the bottom edge of the display, we had to shift our thumb slightly when picking up the smartphone. Samsung has found a more intuitive position in the Galaxy Note 10 , for example. The sensor works fairly reliably, but sometimes the fingerprint is not recognized the first time. It also takes a moment longer until the smartphone is unlocked than with a good, dedicated sensor in the case or the very good in-screen sensor of the Galaxy Note You can also unlock it via face recognition, but this only uses the standard method of a picture comparison.
