According to the latest report, in recent years, Samsung has been developing a folding screen smartphone with two hinges and three panels. We even saw a prototype from Samsung Display.

Now there is more evidence that Samsung is seriously studying the device, which is based on a very detailed patent discovered by LetsGoDigital.

Moreover, the patent shows that the device has the above-mentioned two hinges and three-screen windows, but there are also some details, such as a three-lens camera on the back, an additional display for taking selfies with the main camera on the back, and in-screen fingerprints.

The illustration also shows dual batteries and dual antennas for better signal reception. The advantage of a trifold smartphone is that it does not require an external screen and can be expanded to a larger size, but of course, it is much thicker and heavier than ordinary smartphones.
