Samsung’s One UI 7 Rollout Stumbles Again: A “Serious Bug” Halts Global Plans

Samsung’s journey to deliver One UI 7, its Android 15-based software update, has been anything but smooth. After months of anticipation, beta testing, and repeated delays, the company finally began rolling out the stable version to its flagship devices like the Galaxy S24 series, Z Fold 6, and Z Flip 6. But just as fans were starting to get their hands on the update, Samsung hit another roadblock: a “serious bug” that’s forced the company to pause the global rollout entirely. Let’s unpack what’s going on, why this is such a headache for Samsung, and what it means for Galaxy users.

A Rocky Road to One UI 7

Samsung has long been praised for its robust software updates, with One UI earning a reputation for blending customization, polish, and performance. One UI 7 promised to build on that legacy, bringing a refreshed interface, smarter AI features, and deeper Android 15 integration. But getting it into users’ hands has been a saga of setbacks.

The trouble started early. The One UI 7 beta program kicked off later than expected, leaving Galaxy fans waiting while competitors like Google and OnePlus pushed their Android 15 updates out the door. Samsung’s beta phase stretched over four months, with multiple rounds of updates that tackled minor tweaks but seemingly missed bigger issues. Despite the extended testing, the stable rollout—launched on April 7, 2025, in South Korea and expanded to markets like the US and Europe by April 10—has now ground to a halt.

This isn’t the first time Samsung’s faced hiccups with One UI 7. The company delayed the initial rollout multiple times, citing the need to refine the software. Even when it finally arrived, the update skipped major markets like India and Mexico, frustrating users who expected a more unified global release. Now, with this latest pause, Samsung’s software team is under scrutiny for what’s starting to feel like a pattern of mismanagement.

The “Serious Bug” That Stopped Everything

So, what went wrong this time? According to reports from reliable leakers like IceUniverse and posts across tech outlets, a critical flaw surfaced in the One UI 7 build for the Galaxy S24 series in South Korea. Specifically, users reported that their devices “could not be unlocked normally in some cases,” a problem severe enough to disrupt basic phone functionality. Early speculation pointed to the Exynos 2400 chip in certain S24 models as the culprit, but the issue has since affected Snapdragon-powered variants too, prompting Samsung to pull the update from its OTA servers globally.

The bug’s impact wasn’t limited to the S24 series. Samsung also halted One UI 7 for its foldable flagships, the Galaxy Z Fold 6 and Z Flip 6, which were part of the initial rollout wave. Other reported issues include battery drain and app instability, though details remain scarce as Samsung has yet to release an official statement clarifying the bug’s full scope. Some outlets, like SamMobile, have pointed to a security flaw in One UI 7’s Secure Folder that exposed Gallery content, adding to the list of concerns.

This isn’t just a minor glitch—it’s a significant embarrassment for Samsung. A bug that prevents users from unlocking their phones is about as fundamental as it gets, and its discovery after months of beta testing raises questions about the company’s quality control. As one tech writer put it, “You can’t make this up” after such a prolonged wait for the update.

A Frustrating Wait for Galaxy Users

For Samsung fans, the pause is more than just a delay—it’s a blow to trust. Galaxy S24, Z Fold 6, and Z Flip 6 owners who were gearing up for a sleek new software experience are now left in limbo, with no clear timeline for when the rollout will resume. Older devices, like the Galaxy S23 series or A-series phones, which were slated to get One UI 7 later, face an even longer wait as Samsung prioritizes fixing the current mess.

The frustration is palpable online. Posts on X capture the sentiment, with users venting about the “months and months” of waiting only to see the rollout derailed by bugs. Some have questioned why such a critical issue slipped through Samsung’s beta program, while others worry about the stability of future updates. For a company that’s positioned itself as a leader in Android software support, this stumble risks alienating its loyal user base.

Samsung’s silence isn’t helping. While leakers and tech sites have filled the void with details, the lack of an official explanation or roadmap for resuming the rollout leaves users guessing. Will it be days, weeks, or longer before One UI 7 is back on track? For now, Samsung’s advising users to stick with their current software versions, but that’s cold comfort for those eager to try features like the Now Bar or enhanced AI tools.

What’s Next for Samsung?

Samsung’s in a tough spot. The company needs to act fast to patch the bug, rigorously test the fix, and restore confidence in its software pipeline. The One UI 7 pause affects not just its 2024 flagships but also the broader rollout schedule, which included plans to update 46 devices by June 2025. Devices like the Galaxy S22 and S21 series, expected to get One UI 7 in May, could see further delays if Samsung’s engineers are bogged down with fixes.

There’s also the bigger picture to consider. Samsung’s competitors aren’t standing still—Google’s Pixel devices and OnePlus phones have already delivered stable Android 15 updates, putting pressure on Samsung to keep up. If One UI 7’s troubles drag on, it could dent Samsung’s reputation as a reliable software provider, especially as it gears up for future releases like One UI 8 or the Galaxy Z Fold 7.

For now, Galaxy users can only wait, and hope Samsung gets back on track soon. The company’s got a lot riding on One UI 7, and this latest snag is a reminder that even tech giants can trip up when the stakes are high.
