It's still too early to call a second-gen iteration a make-or-break moment, but it's clear the rest of the AI smartphone hopefuls will be looking to Samsung next week.

Alongside the Galaxy S25 Ultra, Samsung will also update Galaxy AI. How will this define AI smartphones in 2025 and beyond?

The Galaxy S25 Slim will be one of Samsung's thinnest smartphones ever, measuring just 6.4mm thick. Even with the camera module, the total thickness only goes up to 8.3mm. In fact, many of the existing smartphones are already 8mm to 10mm thick without their camera modules.
