Despite taking many extra months to test One UI 7, did Samsung still bungle up something that caused it to pull the update off the air? It certainly seems so: Android 15 firmware for the Galaxy S24 and Galaxy S24+ in Korea and Europe are no longer online on Samsung's servers.

Surprisingly, Galaxy S24 Ultra One UI 7 firmware is still online in both markets, which suggests there may be a different explanation behind Samsung pulling firmware for the other two models off the air, as any issue on one model generally affects the rest.

Firmware for the two devices are still available on Samsung's servers in the USA, so it's possible the issue is with the Exynos 2400 chip that powers the Galaxy S24 and S24+ everywhere except the US, Canada, China, and Japan.

For those unaware, the Galaxy S24 Ultra, like its predecessor, exclusively uses a Snapdragon chip worldwide. The same is true for the Galaxy Z Fold 6 and Flip 6, Android 15 firmware for which are still available.

At the time of writing, there just isn't enough information available for us to come to any conclusion. We will likely have to wait until Monday (April 14) before more details come to light. We'll be sure to let you know as soon as we learn anything, so stay tuned.
