Samsung’s Good Lock One Hand Operation+ module is apparently the best app that is designed well to easily customize the phone to be operated with only one hand. However, a bug initiated within the overall functionality of the app resulted in the quick toolbar always remaining black, but Samsung has some good news about the issue.
With the One Hand Operation+ app, Galaxy users can control and execute functions using just one hand’s simple gestures, making every operation quicker and more convenient.
At the same time, Samsung has already initiated the latest One UI 8 support for the module; however, several users reported a strange issue with the app’s functionality. Basically, users noticed that the background color quick toolbar in the One Hand Operation+ app is not switching colors according to the phone’s theme and always remains black.
Also, the toolbar remains black even when the settings are turned to light mode. But it looks like the Galaxy S24 and Galaxy S25 owners seem to be affected by the problem.
Thankfully, Samsung has already acknowledged the problem occurring in One Hand Operation+ and has confirmed that this issue is happening from the software side due to a bug and will be fixed in the upcoming app update.
Therefore, users are required to wait till Samsung releases a fix for the issue in the next update of the One Hand Operation+ app. Till then, users can enjoy more exciting features that have been enhanced with the update that significantly brought One UI 8 support.
