The Samsung Galaxy Z series (named as Samsung Galaxy Foldables in certain territories since 2022) is a line of foldable smartphones manufactured by Samsung Electronics since 2019, part of the wider range of Samsung Galaxy products. The Z series consists of smartphones running Android with flexible displays, namely the Z Fold line of book-style foldables and the Z Flip line of clamshell-style ("flip phone") foldables.
In 2018, Samsung announced the Galaxy X prototype before manufacture and release of the foldable under the new name Galaxy Fold in 2019. With the 2020 announcement of the Galaxy Z Flip, Samsung's future foldable smartphones are part of the Galaxy Z series. Unlike the Galaxy Fold, the Z Flip folds vertically and uses a hybrid glass coating branded as "InâÂÂinity Flex DisplayâÂÂ. The Galaxy Z Fold 2 5G is the second generation of Samsung's inward fold design introduced with the original Fold. It features a significantly larger front screen than its predecessor, a high refresh rate 120 Hz folding screen, minimal bezels and improved cameras.
In March 2022, Samsung began to rebrand the Galaxy Fold and Flip devices in Ukraine, Moldova and the Baltic States (Estonia, Latvia, and Lithuania) to remove the âÂÂZâ branding from their names. This is due to the Russian invasion of Ukraine, as the letter âÂÂZâ has been used as a symbol by the Russian military and as a pro-war symbol by the Russian government.
In January 2022 at the 2022 CES event, Samsung displayed 2 tri folding concept phones, the Samsung Flex S, and Flex G as both S shape and G Shape style foldables as a preview of a possible tri folding phone. They made their recent appearances in CES 2023, CES 2024, and CES 2025, and in MWC 2023, MWC 2024, and MWC 2025.
In the January 2025 Galaxy Unpacked event, Samsung teased a tri-folding phone during their product roadmap presentation, confirming the development and release date planned for the year.
In December 2025, after months of rumors and speculation, Samsung officially announced the Galaxy Z TriFold in a press release with 16 GB of RAM, 512 GB to 1 TB, two Dynamic AMOLED 2X 120Hz Displays, a 10-inch screen with a resolution of 1584x2160, and a 5600 mAh battery.
