Doogee belongs to a number of Chinese manufacturers, who mostly represent not very distinctive and affordable smartphones, sometimes not afraid to emulate more familiar competition. From time to time, however, it comes with something interesting that would not be ashamed or even more familiar brands.
Yesterday a Youtuber, Mrwhosetheboss managed to get a prototype of the Doogee Mix 4 with a sliding design to hide the headset and the camera.In the mockup featured in the video below.
The upcoming Doogee Mix 4 offers just like many other recent smartphones a display with minimal frames. In this case, however, it has been achieved that the display occupies about 97% of the face of the device. For comparison, Huawei P20 Pro or Xiaomi Mi Mix 2s is 81.9% or 82.9% for iPhone X or Samsung Galaxy S9 +. 
The Doogee Mix 4 uses a 5.99-inch AMOLED display and the manufacturer has managed to achieve a 100% front-end ratio, eliminating both the edges and the cut-out at the top of the display, where manufacturers often solve the problem of where to place the camera yourself. But Doogee came up with another solution.
With its upcoming Mix 4, it used a design that allows you to eject the dual front camera and the phone speaker only when it’s really needed. In the video, a malfunctioning prototype of the device has emerged, but it shows that such a construction could work. the question of quality will, of course, be the processing quality and the service life, because infrequent conversations or in the making of the selfie, the removable construction can be used 100 times per day.
Doogee has not yet released the details of the equipment, but we can see the fingerprint readers integrated in the display and the capacitive volume rockers, as well as the power button, is located on the right side, the dual camera as well as the rear and the USB Type-C port, while the 3.5mm audio jack is probably missing. We expect a flagship-grade hardware, the likes of Snapdragon 660 or Helio P60, but the details are unknown.
The phone is made of metal and definitely is not among the thinnest, you can look at the comparison with Galaxy Note 8. We will wait a moment for the introduction of Doogee Mix 4 because it has not even begun to sell the previous Mix 3 model. with minimal frames, but the manufacturer used a slide-out front camera. Mix 4 will logically begin selling after “April” and the price is expected to remain below $ 300.
