No, the new Galaxy S24 & Galaxy S24+ smartphones do not support advanced Wi-Fi 7 technology. Both will still launch with Wi-Fi 6E, which is the most recent Wi-Fi version. As per the listed devices on the official website, only Galaxy S24 Ultra will support high-speed Wi-Fi 7. It has also been listed on an authoritative Bluetooth SIG website as well as it is confirmed in recent leaks. Now all these phones are in the market so we can confirm their Wi-Fi support.
There is a chance the next Wi-Fi version will come with Galaxy S25, S25+ & S25 Ultra models, but this year it may not be possible. The details mention, Wi-Fi 7 will run on 320MHz channel and supports up to 46Gbps speed. It will provide crazy internet speed for downloading heavy files, streaming 4K content, and uploading 4K or 8K videos.
In a smartphone world, after Galaxy S24 Ultra, Apple’s iPhone 16 Pro & Pro Max variants support this new and advanced Wi-Fi 7 technology to get faster internet access. Slowly, all major smartphone brands are adopting it, and maybe later we can see it on most mid-range devices.
