Update: Samsung's foldable phone may also have a sliding screen

Samsung's Galaxy Unpacked event may have unveiled two highly anticipated foldable smartphones, the Galaxy Z Fold 3 and the Galaxy Z Flip 3 But that's not all the South Korean tech giant has planned for the foldable

Samsung previously confirmed that it was experimenting with rollable and sliding concepts, but that was the only official announcement However, LetsGoDigital reports that a new German patent has surfaced that covers a new rollable smartphone that is reportedly under development at Samsung

The patent reportedly details every aspect of the phone's design Judging from the document, it appears that Samsung's rumored rollable smartphone could feature an outwardly rollable display panel, similar to the Oppo X 2021 or LG Rollable

What is most exciting about Samsung's Rollable is that the entire display of a potential Samsung Rollable could increase by about 40-50% when expanded, at least based on LetsGoDigital's report

As for the rear panel, the patent claims that the phone could feature a vertically aligned triple camera sensor and a horizontally curved screen that could also serve as a secondary display

Similar to what we saw in the Z Fold 3, the phone described in this patent features an under-display selfie camera that is only visible when taking a photo/video on the front The front camera has a 4 megapixel lens, and the rear lens is said to also function as a selfie camera with the help of a potentially larger secondary display

It is also possible that a special dedicated button will be included, which will enlarge or roll up the display when pressed However, we have also seen reports that Samsung may use the power button for the same reason

Samsung may also be planning to introduce an in-display fingerprint sensor on this rumored phone and a special interface that adjusts the display settings depending on whether the phone is fully deployed

However, when it comes to phones with flexible displays, the biggest concern, in addition to water and dust resistance levels, is durability Samsung seems to have gained a foothold in the folding market since then, but these complaints ultimately delayed the launch of the first Galaxy Z Fold two years ago For example, the two newest models are both IPX8 water resistant and have improved other durability features
