Samsung One UI 9 Beta 4 introduces an optional “Secure lock with Power button” setting, allowing users to decide whether opening the power menu from Quick Settings should automatically activate Lockdown mode.

The company first integrated Lockdown mode into the power menu with One UI 9 Beta 2, making it much easier to instantly secure a device.

Once activated, the feature locks the phone and temporarily disables fingerprint and face authentication until the user unlocks it using their PIN, password, or pattern.

With One UI 9 Beta 4, Samsung has refined that behavior by introducing a new Secure lock with Power button toggle. Newly discovered strings confirm the feature is headed to the settings menu, giving users an option that wasn’t available before.

By default, tapping the power button shortcut in the Quick Settings panel no longer triggers Auto-Lockdown. Instead, users can access the power menu and dismiss it without the device locking, returning directly to the app.

Those who prefer the previous behavior can restore it by heading to Settings > Lock screen and AOD > Secure lock settings and enabling Secure lock with Power button.

Once switched on, exiting the Quick Settings power menu immediately locks the phone and disables biometric authentication, just as it did in Beta 2 and Beta 3.

Meanwhile, the change affects only the Quick Settings power button, while the physical side button continues to trigger Lockdown by default.

The adjustment appears to be aimed at balancing convenience with security. Many users open the power menu simply to restart or power off their phone, and forcing Lockdown every time may have felt unnecessary.

If the feature remains unchanged, it should be a welcome quality-of-life improvement when One UI 9 reaches its Stable release.

Samsung Galaxy S26 users will receive the One UI 9 Beta 4 update next week, and it will be an important step. The next release is significant in many ways, including the potential to hit the “platform stability” milestone.

Galaxy S26 users, who joined the Beta Program in May 2026, are closely watching the One UI 9 developments. The rollout of the fourth Beta update will bring a boost to the pace of testing and pave the way for future expansion.

Why do Galaxy S26 users see One UI 9 Beta 4 as an important step?

Samsung has made us think more and more about the next Beta. The first Beta landed upon initial signup in early May 2026. The same month welcomed the second Beta update, and June witnessed the rollout of the third build.

Extended testing period

We anticipated the Beta 4 to arrive by June 30, but it didn’t. Instead, Samsung confirmed earlier this week that the rollout is expected in the next week, starting on July 13.

The company maintained a gap of around two weeks in each Beta rollout. Beta 2 and Beta 3 took approx 15 days to arrive after the rollout of the earlier Beta. Meanwhile, Samsung has stretched the testing of the Beta 4 update.

Samsung’s stability push

Korean community moderator stated that the team will “do our [its] best to release a stable version.” It sounds like a usual statement, but hides the sentiments of the testing team, who is assigned the task to achieve stability.

Near-official release

Another big reason is the timing of the Beta 4 update’s rollout. The build is landing just a week before the company introduces the official One UI 9 version.

The new foldable phones will ship with the Android 17-based One UI 9 official version. Beta testing will continue, but the next versions will approach the Public/Stable rollout.
