The source claims that the Samsung Galaxy S25 Slim has dimensions of 159 x 76 x 6.4mm (rising to 8.3mm if you include the camera bump). For comparison, the Samsung Galaxy S24 Plus (which this is expected to have a similar size screen to) is 158.5 x 75.9 x 7.7mm.

There’s still plenty of uncertainty about the mysterious Galaxy S25 Slim and its release, but it appears the device believed to be the S25 Slim is still being tested out, as evidenced by a discovery made in an unreleased version of Samsung’s One UI 7 software.

Just like the Galaxy Z Fold 6 Special Edition before it, Samsung's next "Slim" flagship could run the risk of not being released in all major markets.
