The HyperOS 3 bug that can damage OLED screens: what's going on with Super Island

HyperOS 3 has arrived with a bang on Xiaomi, Redmi and POCO phonesWith eye-catching new features like the new Super Island and a more complete Always On Display (AOD). But along with the improvements, some rather annoying bugs have also appeared, frustrating many users, especially those with phones with OLED screen and they fear the dreaded permanent burns.

Although the general feeling is that Xiaomi is polishing HyperOS at a good paceIt's not without its share of significant bugs in certain versions and devices. One of the most notorious issues involves the Always-On Display (AOD) and Super Island, which can remain stuck on the screen even when the phone is locked, raising concerns about potential damage to the OLED panel. In addition, there are other bugs affecting stability, network performance, battery life, and key features like NFC and screen mirroring, which the company has already begun addressing with specific patches.

The HyperOS 3 bug that sparks fears of OLED screen burn-in

Since several models in Xiaomi's catalog have made the jump to HyperOS 3Numerous users have reported a specific bug related to Always On Display and the new Super Island. The problem occurs when this dynamic island expands to show extra information from an application, such as notifications or quick controls.

Once the Super Island is deployed, The interface is unable to return to the previous stateThe animation remains frozen on screen with no option to reduce or close it, and the most worrying thing is that locking the device does nothing: the AOD continues to statically display the expanded Super Island.

This behavior is especially problematic on mobile phones with OLED panel, given that Looking at a static image for long periods can contribute to burn-in. or permanent screen burning. Many users, seeing the Super Island stuck on the AOD and unable to move, have quickly associated this bug with the feeling that "HyperOS 3 is burning out OLED screens."

The problem has been even more annoying because Super Island is one of the major new features of HyperOS 3It's a very visible feature; everyone wants to try how it works, and yet those who encounter the bug find themselves with a frozen interface that doesn't even disappear when turning the screen off and on.

Xiaomi has acknowledged that The source of the failure lies in the AOD rendering layers and in the animations of Super Island itself.Although the company has not provided an in-depth technical explanation, everything points to a conflict in how the animation is drawn on the always-on mode, causing the image to freeze without respecting the normal state changes of the system.

What is Xiaomi doing to fix the AOD and Super Island problem?

In response to user complaints, Xiaomi has officially confirmed the existence of the bug And it has opted for a quick response: instead of simply saying that "they are investigating", the brand has begun to directly deploy a corrective patch integrated into the latest version of HyperOS.

This patch, which is already being rolled out gradually, Corrects the anomalous behavior of Super Island on Always On DisplayIn practice, this means that when the island expands to show more information, it can return to its normal reduced state and, above all, that it doesn't remain fixed in the AOD after locking the screen.

According to information provided by Xiaomi itself, The update that fixes this bug has a small file size.of just a few megabytes. This allows for a quick download and a smooth, quick installation, which is a welcome feature for a fix that should be applied as soon as possible to phones with OLED displays.

Furthermore, the company has clarified an important point: Units that have not yet been updated to HyperOS 3 should not be affectedWhen these phones make the jump from HyperOS 2.0 to the new version, they will go directly to a build where the AOD and Super Island problem has already been solved, so those who are still on the previous version don't have to obsess over this specific bug.

While the patch is rolling out to all devices, Xiaomi's recommendation is clear: Avoid interacting with Super Island if you observe strange behavior. And, if there's a serious concern about the OLED panel, temporarily disable Always On Display mode. This minimizes any prolonged exposure of static images on the screen until the system is fully repaired.
