Is the Galaxy S24 a big upgrade over the S23?

It is an evolution: a brighter LTPO screen, the newer Snapdragon 8 Gen 3 and a longer update promise. Camera hardware and battery capacity are close to the S23, so S23 owners gain less.

How does it compare with the S24+ and S24 Ultra?

The S24 has the same chip and main camera as the S24+ but a smaller screen and battery. The Ultra adds a larger display, a bigger battery and a 5x periscope zoom.

Does it support dual SIM and eSIM?

Yes. It takes one physical SIM and one eSIM, and it is unlocked for use on major 5G networks.

The phone and a charging cable. No wall charger or earphones are included, so you need your own USB-C charger.

How long will it get software updates?

Samsung promises seven years of OS and security updates for the S24 series, longer than most Android rivals.

For most people yes, since there is no microSD slot. Heavy video shooters or large game libraries may want more.
