The latest One UI 8.5 build running on my Galaxy S25 Ultra appears to be close to Beta 4, but it still shows signs that the software is not ready for a stable release. As reported by Ice Universe, during regular usage, the device has automatically shut down and restarted twice without any clear reason. These random reboots happened without overheating, heavy multitasking, or battery-related warnings, which makes the issue more concerning for everyday users.
Unexpected shutdowns and restarts are among the most serious bugs in any smartphone software, especially on a flagship device. While beta versions are expected to have minor glitches, stability issues like random reboots directly impact reliability and user trust. For users who rely on their phones for work, navigation, or communication, such behavior can be disruptive and frustrating.
The presence of this bug suggests that Samsung still has important issues to address before rolling out the stable version of One UI 8.5. It indicates that internal optimizations, system-level stability, or power management components may still need further refinement. Even if the software feels smooth overall, these hidden problems can easily delay the final release.
Based on this experience, it seems unlikely that Samsung will rush the stable One UI 8.5 update. The company has a history of extending beta testing when critical bugs are discovered, and this situation appears to fit that pattern. Additional beta builds may be necessary to resolve these restart issues and ensure a reliable experience. Until these problems are fixed, users should be cautious about installing near-final beta builds on their primary devices.
