The first foldable phone was introduced in October of 2018 by Royole. It was called the FlexPai and it beat Samsung to the market by a few months. While that company gets the credit for rolling out the first of these devices, it is Samsung that is credited for making foldable phones popular.
Since 2019, the Korean electronics giant has been making foldable phones as a alternative to its Samsung Galaxy flagship. These are much larger phones that have a second screen that can fold open so a user can watch a movie on a larger screen or multi-tasking from screen-to-screen.
The Samsung Galaxy Z TriFold takes it a step further with three screens that folds out to make an even larger phone. This smartphone contains 16 GB of mobile LPDDR5X SDRAM and 512 GB 3D TLC V-NAND flash from Samsung and the Qualcomm Snapdragon 8 Elite applications/baseband processor.
The following is a partial deep dive into the smartphone conducted by TechInsights.
