Hi everyone,
First-time poster here. I'm an Android developer testing my new app on a few devices, and I've run into a strange issue specifically on my Galaxy S23.
I'm trying to implement a custom haptic effect for a feature I call the "unlimited shake". It's basically a strong, pulsing vibration. It works perfectly on the Android Emulator and my Pixel test device, but on the Galaxy, it's either very weak or just does a single, short default buzz.
I've already checked the basics:
The VIBRATE permission is in my manifest.
I'm using VibrationEffect.createWaveform for modern Android versions.
The battery saving mode is off.
It seems like One UI might be overriding or ignoring the custom pattern I'm providing. Has anyone else experienced this? Is there a Samsung-specific SDK or a known limitation for haptic patterns on recent Galaxy devices that I'm missing?
I've put my Kotlin code snippet, manifest line, and the Logcat output in a document to make it clearer what I'm trying to do. It would be a great help if someone could take a quick look.

Thanks a lot for any help or suggestions!
