If you still have not found out what will be the next trend in mobile devices (beyond folding ones), you only have to take a look at the following Huawei patent to catch up. after the notch and retractable cameras, the next hit will be neither more nor less than the front camera under the screen, and Huawei will have its proposal.
The secret is in the interface

The patent itself does not focus on the hidden camera, but deals with the interface that the phones that carry it will offer, since the sketches show many of the solutions that the manufacturer has in mind for make the most of the screen surface. For example, it shows how the device will show the details of the call when we exit the phone application, or the information about the camera mode that we have selected while taking a photo.

Something quite interesting that we can highlight is that the sketches show a front camera placed in the upper left corner, a location that would be different from the one proposed by Oppo, who chose to place it in the center instead of one end. It may be that for a selfie camera its placement is not essential when it comes to obtaining good results, so we imagine that it is due to the internal distribution of the components themselves.
When is Huawei going to present its camera under the screen?

The sketches spotted could mean very little, as they don't ensure the technology is coming to market anytime soon (we don't even know if Huawei has a working display), but Huawei could be trying to save itself with some kind of special trick. that he has preferred to register and put in his name before the competition gets ahead of him.
maybe for him next Matt 30 It's too soon, so we'll see which terminal will be the one that launches this type of technology that in a few months will be present in most devices on the market. Do you think it is the most appropriate solution to finally end the problem of maximum use on the screen? Time will tell, but if there's one thing we're particularly intrigued about, it's to see to what extent photo quality will be affected by the physical barrier that the screen will place on the camera.
