Oukitel K12 review



The Oukitel K12 phone is delivered in a white cardboard box. Once opened you get the smartphone, screen protection, user manual, needle to open the SIM card slot, OTG cable, USB-C cable, AC adapter and 3.5 mm jack to USB Type C adapter.





The Oukitel K12 has the same features as smartphones with large batteries. That is, it is voluminous and heavy. In terms of dimensions, it is 16.4 x 7.5 x 1.4 cm and weighs 290 grams on the scale. In other words, you are not close to forgetting it when it is placed in your pocket. But well, you can't enjoy a big battery without increasing the weight of the whole thing. The smartphone body has been reinforced with rubber and some parts are equipped with metal plates. In particular the left/right sides and the back where the photo sensors are placed. The metal plates are fixed with Torx screws. You will not have used a suitable screwdriver if you want to remove them (but we don't really see why this would be necessary).

Its weight is one of the negative points, but the use of rubber and metal makes it resistant. Be careful it is not an off-road model (or also called unbreakable). It does not have IP certification (protection index against intrusion by solid and liquid bodies). As a result, you will have to apply careful use, as with traditional smartphones. On the other hand, what is good about this model is that the rubber edges slightly overflow onto the screen to protect it in case of a fall. As a result, the risk of scratching is a little more limited.

At the front we are facing a 6.3 inch screen. The front camera is integrated in a drop-shaped notch and just above it is the listening loudspeaker. At the bottom of the screen, there are the three touch buttons to interact and just below you can see the Oukitel logo. On the right side are the volume and power buttons. On the left side, we have access to the door to insert the SIM card. You open it using the small metal needle provided in the box. On the bottom edge is the USB-C port for charging the battery and the multimedia speaker. There is no jack plug on this model. You will need to use the 3.5 mm jack to USB-C adapter to connect your headphones or headphones in wired mode.

In the back we face the photo sensors. They are both centered in the middle and one below the other. The flash takes place on their left. As we have specified above, they are protected by a metal plate screwed with Torx screws. In the same block is the fingerprint sensor. Oukitel also became printed with its logo on a small metalized plate at the bottom of the rear part. At least people watching this smartphone will not need to ask what its brand is.





The Oukitel K12 is equipped with a 6.3-inch IPS display. There are no defects or problems on this part. IPS technology is up to the task, and it allows for lower energy consumption. The poster is clear, rich in contrast and the colours are natural. The stability of the viewing angle is taken care of for an LCD screen. There are no pixels visible to the naked eye thanks to the definition of 2340 x 1080 pixels. The brightness is also satisfactory. You can read the information displayed even in bright sunlight.

The drop-shaped notch is discreet, so it does not interfere with the use of the smartphone. There is enough space on the left and right sides to display all notification icons. Considering the size of the screen, it is possible to obtain a phablet type experience. The display records ten contact points simultaneously and is scratch-resistant. You interact through the three touch buttons at the bottom of the screen. They can be configured in the system settings.


Performance and System



The Oukitel K12 is equipped with a mid-range SoC, the Helio P35. It consists of 10 cores: 4 Cortex-A73 at 2.2 GHz, 4 Cortex-A53 at 2.0 GHz and 2 Cortex-A35 at 1.2 GHz. On the GPU side we get a PowerVR GE8320 chip and it has 6 GB of RAM. This smartphone will not be powerful enough to play with the graphics fully on the latest 3D games, but for the rest it's OK. Navigation in the system is smooth, applications open quickly and there is no problem for internet searches. The K12 fulfils its role perfectly, the daily use is satisfactory. His Antutu score is about 140,000 points, it is slightly lower than the Xiaomi Redmi Note 7 (143,500 points). You have 64 GB of memory to store your data (photos/videos, etc.) and applications. You can extend the storage capacity with a micro SD card, but you will not need the dual SIM function.

The Oukitel K12 smartphone runs on Android 9.0. The system has hardly been modified by the manufacturer, we get an experience of use close to Android Stock. You will find all the usual options and settings. Lovers of Google's system will not be lost using the k12. On the other hand, what struck us most was the change in the size of the icons. They are bigger on this model, but well it's not really a problem on a daily basis. At worst you can install another launcher via the Playstore. For example Nova Launcher which is very popular with the public. There were no bugs or operating system crashes during our test phase. It has remained fluid and reliable. We would like to point out that an update to Android 10 is unlikely.





When we look at the rear part of the K12, we see two sensors, but unfortunately the second one is fictitious. It is clear that the only sensor is 16 megapixels and cannot compete with the best photophones on the market. We will still be satisfied with obtaining sufficiently sharp photos most of the time and correct color reproduction. However, clear lighting will be required to achieve these results. You can leave the smartphone in your pocket as soon as the brightness is too low. Basically the quality of the pictures taken with the 16 MP sensor is acceptable during the day, but unusable in low light conditions. Oukitel still has some progress to make on the photo part.

The front sensor integrated in the drop-shaped notch is 8 megapixels. The observation is identical to the 16 megapixel sensor. You will be able to make sufficiently clean selfies during the day with good light. On the other hand, the result deteriorates into low light. The bokeh mode is unusable due to its performance. It is made by the software and it is only a simple blurred circle that is applied around the subject being photographed.


Connectivity and Sound



The phone function works very well with the Oukitel K12. The voices are perfectly audible on both sides of the line. Network reception has always been satisfactory. It is compatible with most 4G frequencies.

Supported frequencies:
- 2G: B2 (1900), B3 (1800), B5 (850), B8 (900)
- 3G: B1 (2100), B3 (1800), B5 (850), B8 (900)
- 4G: B1 (2100), B2 (1900), B3 (1800), B4 (1700/2100 AWS 1), B5 (850), B7 (2600), B8 (900), B12 (700), B17 (700), B20 (800), B40 (TDD 2300)

It can also be connected via Wifi (802.11 ac) and Bluetooth version 4.0. The K12 is also compatible with NFC technology. Nothing has been reported about GPS reception, navigation can be done on foot and by car without any disturbance. We regret the absence of a notification LED and a 3.5 mm jack plug. You will need to use the adapter provided in the box to listen to your music in wired mode. We also point out that the quality of the multimedia speaker placed on the bottom part is not top quality (as often on smartphones).





We end with one of the strengths of the Oukitel K12, its autonomy. Indeed, its large 10,000 mAh battery has a score of more than 25 hours on PCMark. Occasional use of the phone provides almost a week of use in a single charge. And people who are addicted to their phones will be able to get almost three days of autonomy. There is no doubt that the K12 is an enduring smartphone. You'll be glad to tell me, considering the size of his battery. Once the battery is depleted, it will take about two and a half hours to fully charge it with the AC adapter supplied in the box.





The Oukitel K12 is an interesting model if you absolutely want a durable smartphone. You are sure not to run out of time thanks to its huge battery. It also offers a clear display and correct performance for everyday use. We will regret its weight and its lack of efficiency in the photo.
