Galaxy Z Fold 4 will improve one of the best things about its predecessor

Samsung has seen incredible success with its new foldable smartphones this year. The company bet it all on the Galaxy Z Fold 3 and Galaxy Z Flip 3 in 2021. It cancelled the Galaxy Note launch and delayed the Galaxy S21 FE to make sure that the chip shortage didn't impact these important products.

The strategy has paid off. Not to mention the fact that these new foldables are certainly some of the best Samsung phones ever made. So it goes without saying that their successors may be equally, if not more, impressive.

Galaxy Z Fold 4 gets better at hiding its selfie camera

The Galaxy Z Fold 3 has a lot of “firsts” to its name. It's the first foldable smartphone from Samsung to feature support for the S Pen. It's also the first to boast an IPX7 rating for water resistance. Lastly, it's the first Samsung phone with a UDC or Under-Display Camera.

Samsung has used the UDC technology for the selfie camera on the internal foldable display. When not in use, it disappears from view. The pixels on the display make way when the camera is to be used and it emerges from below the panel.

Samsung has been working to introduce its UDC technology to make it appear even more seamless. The improvements might also allow the company to use better sensors than the one currently used for the Galaxy Z Fold 3.

Reports from South Korea indicate that the equipment for manufacturing OLED panels with Samsung's second-gen UDC technology is already being used. A small number of display panel test samples have also been made.

Samsung fans will certainly be excited to see everything that the company introduced with the Galaxy Z Fold 4. They'll have to wait a while, though, as the device isn't expected before the second half of 2022.
