A few years ago, protected smartphones were perceived as a kind of wonder. However, today in the arsenal of almost all manufacturers there is at least one such model. And some companies are so inspired that they release a whole series of strong smartphones for travelers and adventurers.

The S50 is Doogee’s fourth secure smartphone. It boasts not only a strong body but also good performance. And there are as many as four cameras installed in it, which should, according to the assurances of the company, provide bright and clear photos. Like it or not, we will tell in this review.

Specifications Doogee S50 is not inferior to any Chinese smartphone mid-range. It is based on SoC Helio P23, which MediaTek at the time of its appearance, in August last year, called it a “premium” solution for middle-class devices.


Protected smartphones are designed not only for travelers but also for people working in difficult conditions. Builders, auto mechanics, rescuers, miners, and metallurgists need reliable gadgets that are not afraid of dust and dirt. These low budget smartphones that are not afraid to bathe in a puddle or drop on the cement floor.

Doogee S50 fully meets these requirements. During testing, we buried it in the sand, bathed it in seawater and dropped it on concrete. All water procedures smartphone endured without any consequences. Dense rubber plugs reliably block access to the inside of the phone, so you can use it directly in the shower or even underwater.

Screen and sound

The Doogee S50 is equipped with a 5.7-inch screen with a resolution of 1,440 × 720 pixels. It has an elongated shape with a trendy 18: 9 aspect ratio today, but because of the thick frames on the sides, it does not look as elegant as most modern devices.

Screen and sound

We have no complaints about the quality of the picture. The display has the right white balance, good contrast and color reproduction. If you have individual requirements for the image, then they are easy to achieve using the MiraVision settings. The smartphone supports LiveDisplay technology, through which you can set individual settings for day and night modes, as well as the rules for their automatic switching.

The range of illumination of the screen is regulated within wide limits. With maximum brightness, the smartphone is comfortable to use even on a street flooded with sunlight, which may be important for travelers and tourists. However, for reading at night, it is better not to use the Doogee S50: even at the minimum level, the light still remains too bright. The sound in protected smartphones is a separate, rather complex engineering task. On the one hand, the manufacturer needs to take care of reliable protection of the external speaker, and on the other hand, it is necessary to ensure its high-quality and free sound.

The first task, as shown by our water tests, in Doogee successfully coped. But with the quality, alas, did not work out. The gain level is quite high, but the sound of the built-in speaker is so flat and nasty that you constantly want to make the volume a little lower. And then turn off and exhale with relief.


Smartphone Doogee S50 is built on the basis of the chipset Helio P23, which provides sufficient performance in all, without exception, user tasks.


The smartphone is equipped with a battery with a capacity of 5,180 mAh. In the PCMark Work 2.0 Battery Test, which measures the lifetime of a device when performing typical user tasks, the Doogee S50 lasted just over 16 hours. This is an excellent indicator that puts this smartphone on a par with such recognized long-livers as Xiaomi Mi Max 2 and Umidigi S2 Pro.


Making a final opinion on the results by inflexguide of testing the Doogee S50 was not at all difficult.

This smartphone has everything you might need during a long trip. Its case reliably protects from water and dust, the battery lasts for several days, and the camera allows you to take beautiful pictures of all the sights and natural beauties. There were no complaints about the quality of the screen and the performance of the device.

The only remark concerns the appearance and weight of the smartphone. Doogee S50 has such a brutal design and solid weight that not every buyer will like it. The expediency of using this smartphone as the main device in everyday life is very doubtful for us, therefore, most likely, it is more suitable for it as a backup device for extreme entertainment, hiking and traveling.
