Samsung pushed the stable One UI 8.5 update on May 6, 2026, starting with the Galaxy S25 series in South Korea before expanding globally on May 11. The Galaxy S24 series, Z Fold 7, Z Flip 7, and foldables like the Z Fold 6 and Z Flip 6 followed shortly after.

What to do if you have a general One UI 8.5 problem not listed here
Any major software update comes with a settling-in period, and One UI 8.5 is no different. Within days of the rollout, users across Samsung’s community forums, Reddit, and tech publications started flagging a range of problems, from aggressive battery drain to missing camera features and app crashes.
Some of these are confirmed bugs Samsung is actively fixing. Others are intentional changes that caught users off guard. This article covers all of them and tells you exactly what to do about each one.
Here is a quick look at everything this article addresses:
Galaxy S25, S25+, and S25 Ultra users are reporting heavy battery drain after installing stable One UI 8.5. One user on Samsung Members posted on May 12, 2026, that their Galaxy S25 drained 85% of its battery in a single day, with only 3 hours and 46 minutes of screen-on time. Their description: the drain was much more aggressive than during the beta phase.
The same pattern is showing up on unlocked S25 Ultra units in the US and on some S24 Ultra devices that received the stable build around May 9 to 11.
After a big OS update, your phone spends a few days re-optimising background apps and reindexing storage. This can cause temporary battery drain. Give your phone 7 to 14 days before concluding. If the drain continues beyond that, work through these steps:
T-Mobile users: There is a specific fix for you. Keep reading below.
A Samsung US community moderator has confirmed that the latest version of the Mobile Services system app is causing unusually heavy battery consumption on T-Mobile Galaxy S25 devices. Samsung says a proper patch is coming, but you can fix it yourself right now:
The app rolls back to its factory version, and the drain stops. This workaround has also helped non-T-Mobile users, so if your carrier is different and you are still seeing a drain, it is worth trying.
After updating to stable One UI 8.5, some Galaxy users open the Enhance-X photo editing app and find that features like Filter Styles and Glow are simply gone, with no error or explanation. The app shows as installed and up to date, but those editing tools have disappeared from the in-app library.
There is an important warning attached to this bug. One user tried to fix it by uninstalling Enhance-X and reinstalling from Galaxy Store. After uninstalling, the app stopped appearing in Galaxy Store search entirely, leaving no way to get it back. Samsung has not documented a re-installation path for this case.
Samsung’s camera team has officially acknowledged the bug and confirmed that they are working on a fix. The plan is to roll it out in stages, device by device, and the moderator said it could take up to three days once the rollout begins.
The single most important thing: do not uninstall Enhance-X. Wait for Samsung to push the fix automatically. Here is what to do in the meantime:
On One UI 8.5, the Samsung Voice Recorder app crashes the moment you try to summarise a recording that has already been transcribed by Galaxy AI. The crash occurs only when the Galaxy AI privacy setting “Process data only within the device” is turned on. With cloud processing, the bug is less consistent, but the on-device path is broken.
This affects any Galaxy S25, Z Fold 7, Z Flip 7, or S24 series device running One UI 8.5 with the affected Voice Recorder build. Samsung has officially confirmed the bug and has already released a fix through Galaxy Store.
The fix is already out. You just need to update the app:
One UI 8.5 was positioned as the update that would bring Galaxy S26-level AI features to older Galaxy phones. When the stable build arrived for the Galaxy S25 series, users quickly discovered that at least nine features available on the S26 are simply absent from the S25, even though both devices run the same OS version and share similar hardware capabilities.
The backlash started on the Korean Samsung community forums and spread quickly. Galaxy Z Fold 7 owners reported the same gaps, making it harder to attribute the issue to hardware differences, since the Fold 7 uses the same chip class as the S26.
Based on Samsung Members reports and coverage by SammyGuru, PiunikaWeb, and Digital Trends, here are the features that did not make it across:
Samsung has made no public statement about why these features were left out. The hardware argument carries less weight here than usual because several of these features depend on nothing specific to the S26’s chip or sensors.
There is no Samsung-approved fix because this is not officially a bug. Your options right now are:
When you pull down your notification shade, you may notice the Notification settings button suddenly appear smaller than it should be and sit off to the right instead of in its correct position. Swiping the panel closed and reopening it snaps the button back to its normal state.
This is a visual bug in the notification panel layout. It was first spotted by Sammy Fans during One UI 8.5 Beta 6 in late February 2026. It was still there in Beta 10 in April 2026. Then made it into the stable release without being patched, meaning Samsung did not resolve it across the entire five-month beta cycle.
Samsung has not officially acknowledged this one. The button still works when you tap it, so it is a cosmetic issue rather than a functional one, but it is frustrating to see in a stable release.
The only fix right now is a simple workaround:
On One UI 8.5, you will not find Dual Recording or Single Take in the Modes section of your stock Samsung Camera app. Under One UI 8.0, both were there by default. After updating, users assumed Samsung had removed them entirely.
Samsung did not remove them. The company moved both features into the Camera Assistant module inside the Good Lock app. A Samsung camera team moderator confirmed this is a deliberate design decision, not a bug. Still, the shift was made without clear communication, which is why many users thought the features were deleted.
This affects every device receiving One UI 8.5, including the S25 series, S24 series, Z Fold 7, Z Flip 7, Z Fold 6, Z Flip 6, and the Galaxy Tab S10 and S11.
Both features are still accessible. You just need to go through Good Lock:
If Camera Assistant does not appear in the Galaxy Store in your region, you can find the latest APK in SamMobile’s database and sideload it, though that route is best for users who are comfortable doing so.
