Describe the actual behavior

On the Galaxy S25, the camera only detects distant hands located in the bottom right corner of the screen. When a hand is placed in the center, MediaPipe fails to recognize it.

Describe the expected behaviour

In the demo version provided by MediaPipe, the camera index cannot be selected, and even when uploading a hand image, it is not recognized. The Galaxy S25 seems to misidentify the camera or only detect specific positions (a small palm in the bottom right corner).

This is the only area where hand landmarks are recognized on the Galaxy S25

Hi @hongsoonill,

To further investigate, could you share screenshots where hands are positioned in the middle of the frame and are not being recognized? We also request testing with live camera input and a variety of static images to assess the consistency of the detection issue.

Thank you!!

Not sure if it helps, but we are experiencing similar issues with object detection in JS on the S25. The S25 seems to prefer objects to be really far away before it detects them.

Here's a similar scene between my iPhone and my S25.

S25:

You can see in the S25 image that the objects that are further away on my desk are detected, but the PS5 controller is barely getting a box on it (and is wrongly categorized). The iPhone has no such trouble.

Sorry if this isn't quite the same problem as the original issue, but it feels somewhat related to me.

Great! My company bought me an S25 just for this purpose, so please don't hesitate to reach out to me if you need any help with testing things. We are keen on getting this resolved for our customer base.

@hongsoonill, @mackinleysmith,

We tested the S24 Ultra today, and there appear to be no issues. We will check if we can reproduce the behavior on the S25, although we currently do not have it.
