Not a good situation, but as long as the Exynos 2400 is better than the SD Gen 2 from the S23 series, it should be ok. Just as long as efficiency and thermals are on par with the Snapdragon Gen 3.

The issue is you won’t get an S24 Ultra for those prices. It will be well over £1000. Not sure its worth £300-400 more for an S24 Ultra vs S23 Ultra.
