Software
The Samsung Galaxy S24 phones were released with Android 14 with Samsung's One UI 6.1 user experience. Samsung has promised 7 years of security patches and OS upgrades similar to that of Apple's.

They use Google's on-device Gemini Nano, already used by their own Pixel 8 Pro.

Hot S Pen
Some users noted that the Galaxy S24 Ultra's S Pen "absolutely reeks", with a smell that was likened to "burnt plastic". A moderator on Samsung's EU forums explained,

"This isn’t anything to be concerned about. While the S Pen is in its holster, it is close to the internal components of the phone, which will generate heat while in use, and cause the plastic to heat up. This can smell like burning, but it is similar to the smell you might experience after leaving your car in the sun for a few hours. The seats and plastic fittings in the vehicle might smell hot, but this will diminish after it cools."
