Samsung's latest One UI 8 rollout has hit another snag, and this time it is the Galaxy S23 series caught in the crossfire. What started as a promising Android 16 update has turned into a stop, start, stop pattern across multiple Galaxy generations. The company has now completely yanked the firmware from its distribution servers, according to Android Central, making it inaccessible to users in European and Indian markets. Samsung is quiet on the reasons, but a wave of battery drain complaints on social media points to the technical headaches behind this ambitious Android 16 transition.
Why Samsung keeps hitting the brakes on One UI 8
Samsung launched the Android 16-based update for the Galaxy S23 series on September 29, as reported by Android Central. Then came another pause, a now-familiar beat that has already hit the Galaxy S22 and S24 series. Samsung suspended the One UI 8 update for the Galaxy S24 series nearly a week ago, according to the same source. Before that, the Galaxy S22 series saw the same treatment, with Samsung pulling the update just one week after its initial release, per SamMobile.
The pattern is telling. Critical issues are surfacing after real-world deployment, not during internal testing. These repeated post-launch suspensions suggest a reactive approach to firmware stability and raise fair questions about how Samsung vets major Android version transitions.
What is actually going wrong with the update
Battery performance problems top the list. Multiple users have documented severe battery drain after installing the update, according to Android Headlines. One Galaxy S23 FE user said their phone cannot last more than three hours after updating, as noted by Android Central, a devastating blow for a flagship device.
Not everyone is affected, which complicates the hunt for a fix. Some Galaxy S23 owners report normal battery life, hinting at interactions with specific device configurations, usage patterns, or background app behavior under Android 16's power management.
There are also isolated feature failures. Reports of broken secure folder functionality on some Galaxy S23 units, per Android Headlines, point to deeper integration friction between One UI 8 security changes and existing Samsung services.
The broader impact across Samsung's Galaxy lineup
The S23 pause is only one chapter. Samsung has officially paused the Android 16 rollout for both the Galaxy S23 and Galaxy S24 series, according to 9to5Google. The suspensions have also touched the Galaxy Z Fold SE, Galaxy S22, and Galaxy M53 models, as reported by Gizchina. That breadth suggests a compatibility problem between Android 16 and Samsung's One UI layer, not a single-device fluke.
There is at least a sliver of progress. Samsung has restarted One UI 8 distribution for some Galaxy S22 variants in certain regions, though the Galaxy S22 Ultra remains without the update, per Notebook Check. A slower, segmented rollout lets Samsung identify which configurations behave reliably.
What this means for Galaxy users moving forward
Based on Samsung's usual crisis playbook, fixes tend to arrive on a short clock. The company typically resolves these firmware issues within a week or two once internal testing is complete, according to Gizchina. Rollouts are expected to resume globally before the end of October 2025, per the same source.
If you have not received the update yet, you will remain on your current Android 15 build until Samsung ships a more thoroughly tested version, as noted by Android Headlines. It is a buzzkill for early adopters, but it keeps you out of the battery-drain danger zone.
If you are already on One UI 8 and running into problems, the only play right now is to wait for the next stable patch. The upside, small as it is, is that Samsung is willing to halt major releases to protect the user experience, even if it means taking heat for delays.
Bottom line: the pauses are frustrating, but they show a shift toward stability over speed. By tapping the brakes across multiple Galaxy generations, Samsung is at least listening to user feedback while it works through the Android 16 integration mess.
PRO TIP: If your battery nosedives after updating to One UI 8, track your usage and send a detailed report through Samsung Members. Device model, apps in use, and how fast the percentage drops can help engineers pinpoint the root cause and ship targeted fixes faster.
