What's the difference between Samsung Z Fold 4 and Fold 3?
The rendering of Samsung Z Fold 4 shows that, like Samsung Z fold 3, it adopts a foldable horizontal design and is equipped with a pen. In addition, there is no obvious opening in the internal screen, so the camera under the screen should still be used. However, many changes have taken place in some areas. Most obviously, a P-type camera layout design similar to the recently released Samsung S22 ultra is adopted, which means that the image intensity of Samsung Z fold 4 will be further improved. In addition, there is no obvious opening on the external screen, so you can also use the camera outside the screen.
What is the unlocking method of Samsung Z Fold 4?
In unlocking, most folding mobile phones now adopt side fingerprint recognition. Samsung Z fold 3 adopts this design, but Samsung Z fold 4 is said to adopt off-screen fingerprint recognition. It is worth noting that last year, the media exposed Samsung's double-sided fingerprint identification patent. According to the patent description, Samsung's double-sided fingerprint sensor will be placed between the inner screen and the outer screen. With this technology, the internal and external screens of the folding mobile phone can be unlocked, which is also a great progress of the folding mobile phone.
Samsung Z Fold 4 may not match the pen slot.
Samsung suspended the development of Galaxy Note series and paid more attention to Galaxy Z folding and Galaxy Z flip series folding equipment. For people who like to take notes and draw pictures on their mobile phones, the new folding mobile phones support handwriting input, but the disadvantage is that there is no dedicated pen slot. According to the latest news, the next generation Galaxy Z fold 4 may not have a special pen slot.
