Volla Phone Smartphone Review - Cellphone with special data protection

Safety first. You want to use your smartphone without the ubiquitous trackers from Google and Co? Then the crowd-funded Volla Phone offers two solutions: Either Android without Google or Ubuntu Touch. But what does that mean for everyday use?

Case, features and operation - Operating system selectable

The case of the Volla Phone relies on plastic, and the stability is okay. However, the smartphone does not look incredibly high-quality for its price range.

The Volla Phone comes with VollaOS, which is based on the Android Open Source Project, but does not include Google services and apps. Instead, the system uses the Aurora Store, a copy of the Google Play Store, but it can be used without a Google account. Thus, many apps are available, but of course you cannot use apps that rely on Google services. The structure of the operating system has also changed, so the OS relies on a so-called springboard that appears after unlocking and where you can type in what you are looking for. The smartphone then starts an Internet search or if you start with an @ a contact search, you can then send an email or SMS directly to the respective contact. The black and white design of the system saves energy. The basis is Android 9, the security patches are from October 2020 and are already slightly outdated at the time of testing.

Alternatively, you can get the phone with Ubuntu Touch, the mobile version of the well-known Linux distribution. This naturally offers Linux lovers the possibility to customize the system via terminal. In addition, there is almost no malware and the smartphone can be connected to a monitor and can then be used together with mouse and keyboard like a normal Linux PC. However, this variant is really only recommended for Linux connoisseurs, everyone else will miss apps known from Android. The system is also not really optimized for the Volla Phone, so the round monitor edges cut off the time display and the notch is not really taken into account in the display.

NFC is available, but Bluetooth is only available in an older version. The same applies to the Wi-Fi, so you have to make do with Wi-Fi 4 speed.

Cameras - De facto single camera

Recording front camera
Recording front camera

The 16-megapixel camera on the back is supported by a small lens, but you cannot use it for your own photos. Other phones in the price range offer much more flexibility here.

Strictly speaking, it is a single camera that overall takes good pictures for the price range, but a bit more light intensity would have been nice. The quite a lot of details that the camera displays are pleasing. In low light and high contrasts, the picture quickly becomes blotchy and the brightening could be better here as well, but at least you can still recognize some details.

In the test lab, on the other hand, the camera has a hard time recognizing anything at 1 lux. In good light, there is a significant drop in sharpness towards the edges of the picture and slight contrast problems in some areas.

The front-facing camera has a meager 4 megapixel resolution. Volla tells us that it is supposed to be a 16-megapixel camera, but we can only take 4-megapixel pictures. We will not change the specs for the time being until the issue is clarified.

Display - Bright and with a blue cast

The resolution of 2,340 x 1,080 is standard for the class, and the refresh rate is 60 Hz. The black level is mediocre, but the brightness is quite good, which also results in a decent contrast ratio.

There are significant color deviations and a blue cast in the factory settings.

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
26 ms ... rise ↗ and fall ↘ combined↗ 11 ms rise
↘ 15 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 49 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.1 ms).
       Response Time 50% Grey to 80% Grey
54 ms ... rise ↗ and fall ↘ combined↗ 27 ms rise
↘ 27 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 87 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.2 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

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9719 (minimum: 5 - maximum: 151500) Hz was measured.

Performance, emissions and battery life - Good runtimes

The MediaTek Helio P23 in the Volla Phone cannot keep up with other current mid-range phones in terms of performance. The system can be used fairly smoothly in everyday use, but stutters can occur in more demanding tasks.

Warming remains below 40 °C even under full load, so it is noticeable but by no means unpleasant. The speaker can get quite loud and is suitable for occasionally listening to music tracks. The 3.5 mm port and Bluetooth transmit a clean audio signal.

The battery lasts just under 17 hours in our WLAN test when using the Volla Phone with VollaOS. It is 2-3 hours less with Ubuntu Touch. That is a good battery life. Charging is done with up to 18 watts, which is enough for charging times around 2 hours. Wireless charging is also possible, a nice unique selling point in this price range.

On review: Volla Phone. Provided by Volla.
On review: Volla Phone. Provided by Volla.

Volla collected money for its secure smartphone via crowdfunding and has now delivered quite punctually. It delivers on its promise of a more secure OS without Google, lets you choose whether you want to have Android on your smartphone at all, and there are even first approaches for a Sailfish OS port, so the community seems to be very active as well.

From a technical point of view, the Volla Phone is nothing special when compared to other smartphones in the same price range. The WLAN is slower, the camera not as flexible, the memory slower. But at the same time, Volla has managed to keep the phone suitable for everyday use: You surf the web with a quite stable Internet connection, take decent pictures and can even charge your smartphone wirelessly, which is hardly supported by any other smartphone in this price range.

The Volla Phone is not perfect, but those who want better data protection will get a good smartphone here.

The battery lasts quite long and the screen's resolution is quite high. At the same time, we do not notice any PWM and the brightness is okay. We only find it really annoying that the USB-C port picks up a bit shakily and loses contact from time to time.

Clearly, Ubuntu Touch is rather something for experienced Linux users, newcomers will have a hard time at first. And even a Android without Google services has limitations. However, those who consciously accept it will get a good phone with the Volla Phone and can better control their own data.

Price and availability

The Volla Phone is currently available on the manufacturer's website or via Indiegogo, but not in retail stores. The price is 359 Euros.
