Samsung Galaxy S25 series leaks are popping up now and then as we inch closer to its rumored January 2025 release window. The latest one suggests that a new member will join the lineup besides the typical trio.

Samsung might be working on a “Galaxy S25 Slim” model, with similar rumors to the ones about a “Slim” iPhone 17 in 2025 that may replace the iPhone Plus. South Korea’s ET news first reported on it, saying Samsung might release a slim smartphone during the second quarter of 2025 (April – June) as a follow-up a few months after the rest of the Galaxy S25 family makes their debut.

The Galaxy S25 Slim will supposedly pack an 'Ultra' camera. Samsung may release the Galaxy S25 Slim in May or June with similar camera specs to the Z Fold Special Edition. The slim phone may have a smaller battery capacity to maintain a sleek design, focusing on thinness.

A recent report revealed that the upcoming Samsung S-series will include a new model called the Galaxy S25 Slim, in addition to the Galaxy S25, S25+, and S25 Ultra. Speculation suggests that the S25 Slim will be designed to compete directly with Apple’s rumored iPhone 17 Slim,

Samsung could announce four Galaxy S25 models in 2025. That fourth phone, the "Galaxy S25 Slim" is designed to take on Apple's upcoming "iPhone 17 Slim."
