What issue concerning the volume slider in iOS 17 was reported in the DeviceTalkForum discussion?
Support: Users have noticed that when quickly lowering the volume to zero with a downward flick gesture in the control center, the volume slider automatically increases to a random level afterward. This behavior is particularly noticeable when swiftly reducing the volume from maximum to zero. However, this issue cannot be reproduced when media is playing or during screen recording.
In previous iOS versions, the volume would remain at zero as set by the slider. This issue was observed on an iPhone 14 Pro Max running iOS 17.0.2.
