Samsung initiated One UI 8.5 Beta last December, but the Galaxy S25’s Stable update still has work left. While users await the fourth Beta build, Samsung is likely busy addressing major internal glitches.

As spotted by IceUniverse, the latest One UI 8.5 Beta on Galaxy S25 Ultra is causing random restart issues, hinting at a potential delay in the Stable update’s rollout.

The tipster is running an internal build of the software, which is a newer version than the Beta 3 available to Beta participants. Bugs in a newer release indicate that some work sis till left before kicking off the Stable rollout.

The source revealed that the bug is automatically shutting down and restarting the device. All this happened twice, signaling a critical glitch. It must be addressed before bringing the build to the public as the fourth Beta firmware.

Functional issues can be considered in Beta testing. Meanwhile, issues like shutdowns and unwanted restarts can be disastrous. Think you are recording something important, and your phone shuts down for no reason.

It could even happen when you are on a phone call and discussing a critical topic. That said, Samsung hasn’t yet dropped a new Beta build. It’s expected this week, but only when the bug is resolved and verified by engineers.

Is Samsung really delaying Stable?

No. Samsung has never pledged One UI 8.5 will be available in February. The company has already announced that the official rollout will begin with the Galaxy S26 series. The flagships arriving on February 25, with the first sale slated on March 11.

If you’ve participated in the Beta Program, stay joined; otherwise, you may not get access to the activity again. A fresh Beta will be provided as soon as it hits the necessary benchmarks in testing by Samsung engineers.
