I cannot reproduce this on my test devices. Were you able to reproduce this on multiple different devices?

Just passing through... I've have seen this with some Android phones (specifically with a Nokia device on Android 10). No idea why some phones allow it... But it never seemed to me to be a plugin kind of bug.

If the firmware and hardware in Android allow it... Should the plugin really be concerned about preventing this?

Hi everyone, I could replicate the same issue using a Samsung Galaxy A11 (Android 12) physical device

I recall this is a defect from the firmware (seen in Samsung phones), maybe you can try to "normalize" it by off and on before the next scanning

Oh yeah this also happened to me with my samsung galaxy a12 (android version 13) phone, at first it was unusual but i never paid much attention to it until i found this issue
