8 Types of Foldable Smartphones: New and Used

When it comes to foldable smartphones, the key factor is not just the fact that the screen folds, but rather 'what you do when it’s folded and what you do when it’s unfolded'. The Galaxy Z Fold series is strong in displaying documents, maps, and multiple apps broadly, while the Galaxy Z Flip and motorola razr series focus more on compact portability and external screen utilization. Even among foldables, the intended use is entirely different.

This list covers not only the latest products like the Fold7 and Flip7 but also older generations like the Fold6, Flip6, and 5th generation models that you can find in the used market. We will compare the latest models in terms of thickness, external screens, and warranties, while focusing on hinges, internal screens, and battery conditions for the previous generations rather than pricing. This serves as a guide for both first-time foldable buyers and those considering entering the used market.

If you need a large working screen, start by looking at the Fold models, and if portability that fits in a small bag is important, then consider the Flip models. After that, you can decide whether to pay the cost for the thinness and performance of the latest generation or enter with a better-condition previous generation at a lower entry cost, which will quickly narrow down your options. It’s also important to check if the apps you frequently use on the external screen are actually supported, as this will affect your satisfaction.

Especially with used foldables, don’t rely solely on photos; check personally if it unfolds completely, ensuring that there are no black dots, gaps, or touch issues around the creases. Look for hinge noise, frame impacts, and check if the protective film has been replaced along with any official repair history. If the total cost, including remaining warranty and the possibility of insurance transfer, is not significantly different from a new product, then opting for a new device may be safer.
