Doogee V20 Pro

Technical specifications

Everything is good, both the RAM and thermal imaging are impressive, but the 6000 battery is highly unsatisfactory. If it were not for that, I would switch immediately. The problem is that I currently have an Oukitel wp19 with a 22000 battery. Such a switch would probably be impossible to tolerate.

The phone is good. Compared to the Ulefone Armor 9, there is a massive difference. This applies to the thermal imaging, the camera, and the operating speed. Most importantly, it is possible to disable those inconvenient gestures. During two years of using the UA9, I could not get used to them. Here, there is a traditional navigation bar. Regarding the battery... well, the phone is already full of features and a larger battery would be excessive ;)
All joking aside, it easily lasts 2-3 days even with frequent YouTube usage. A larger battery would mean it would have to be carried in a backpack like the old Centertel devices. In this case, the weight and size are acceptable. Also, the AMOLED screen is excellent. In such a robust device, there is finally a feature typically found in flagship models.

The phone does not have induction charging (please correct the specification). The radio application does not work. It does not detect the connection of USB-C headphones. The headphones work correctly during music playback and phone calls. Compared to my old XCover4, it is a Mercedes. The back cover gives the phone a business appearance. And the built-in stand is extremely practical in the office. Unfortunately, the first time I put on my shoes, the phone slid out of my side trouser pocket. A fall of the phone from 30 cm onto the ground ended the life of the back cover. And here the main flaw of the phone is revealed, which is its heavy weight. My previous phone never fell out of the same pocket. In Snickers work trousers, the dedicated pocket is too small and the side pockets are too large, and the phone painfully hits the leg. However, wearing the phone on a lanyard hung around the neck is an option only for masochists. The phone, placed in a kayak case and thrown into the water, immediately sinks to the bottom. On a river, such a maneuver means the definitive loss of the phone. The magnetic mount in the car does not hold. I did not even dare to mount my heavy device on a bicycle mount. In my opinion, the second significant flaw is the lack of an induction charger. Other minor flaws concern the early stage of development and are theoretically removable with a software update. For example, in text editors, it incorrectly inserts Polish characters. When taking photos horizontally, it displays the photo vertically on the full screen. The same applies to the incorrect readings of the levels. While being carried in a pocket, it unlocks itself. I can explain some of these malfunctions by the fact that I do not yet fully understand how to operate the new phone. As for the advantages, in addition to those in the specification, there is the navigation with the MAPY CZ. program during holidays in the mountains. And proving to my dear wife that I am leading the right way. Regards.
Thank you for the correction and I apologize for the error. Regards. (jf)

Follow-up review after 2 months of use. I will list the cons, as the pros were mentioned earlier.
1. I received a unit with a crookedly mounted thermal camera. I did not notice it before, but in a photo with the horizon, it tilts a few degrees to the right. It is more amusing than bothersome, simply a Chinese product.
2. The thermal camera lenses scratch quickly. This is a more significant problem because it affects the accuracy of the readings.
3. Applications crash from time to time, especially YouTube... I have the impression that it is a memory issue.
3. The night mode is a complete disaster, however. I do not know if the AMOLED screen is unable to handle it? The day mode is excellent.
4. Someone already mentioned that it has a habit of turning on while in a pocket.
5. The proximity sensor malfunctions during calls; after the call is finished, some strange things are suddenly activated by the ear. One must be careful.
Considering its advantages and the fact that I managed to purchase it on Aliexpress for half the price offered in Poland, it was worth it. But if I had to buy it in a local retail chain for well over 2,000... I would be slightly irritated.

I have been using this phone for over a year, so I already have some understanding of it (and I have used several "rugged" phones before), and my expectations were high. The phone may not have exceeded them, but it met most of my expectations. The phone is large and its weight is noticeable in the pocket, which is a plus for me. Its water resistance was tested by Lake Wigry and it passed the test with the highest rating; even being 15 meters underwater without any protection did not harm it. The camera works correctly but is not impressive (though that is not why I bought it). Night vision performs very well; you will not encounter any obstacles in the dark. Despite my lack of caution during use, the sensors still work efficiently and do not malfunction. I believe that the price one had to pay for it is worth what is received, provided that someone knows how to use its features.

I had it for only a short time (maybe two weeks). The first time playing with my child in a paddling pool and the device stopped working. Water got inside through the speaker. Besides, it was uncomfortable and heavy. I did not even have time to check how the device works in general, but I do not recommend it anyway. The store did not believe that the water got inside on its own and they did not want to accept the warranty claim. [...] - I will not buy a device of this brand again.

I have had the phone for over a year and from the start I have had a problem with the screen autorotation, as the sensor malfunctions and needs to be calibrated frequently :(. I am currently looking for a replacement... also with thermal imaging, because that part works very well here and is useful to me quite often. Except for this very annoying flaw, I recommend this phone. I believe I received a defective unit, as I have not found anyone online with a similar problem.
