Steps to reproduce the bug

Clear TalkBack voice prompts are needed to enable visually impaired users to perform the operation.

Actual behavior

TalkBack does not provide clear feedback during drag operations.

Screenshots/Screen recordings

Additional information

This issue report was generated with the assistance of a large language model (LLM) and reviewed before submission.

Task 1: Presence of drag-operation controls
Yes. The page includes drag-based controls for cropping and adjusting the image (dragging the crop frame/edges and repositioning the image within the grid).

---

Task 2: Interface category and relevant controls
The page belongs to an adjustment and selection interface.
Relevant drag-related controls include:

• Crop frame / image canvas (drag to reposition the image within the crop area)
• Crop handles or edges (drag to resize the cropping region)

---

Task 3: Mandatory nature of drag operations and alternatives

• Is drag operation mandatory: No.
  Users can keep the default crop and proceed without dragging.

• Alternative interaction provided: Yes.
  The interface offers alternatives such as:

  • Tap-based buttons (e.g., confirm, preset crop options, rotate)
  • Non-drag controls to apply or accept default adjustments

I assume you are using two-finger gestures to move the crop handles?

TalkBack does not provide clear feedback during drag operations.

What type of feedback are you looking for? What should be announced after every move or adjustment operation?

I can't find any editing app that provides TalkBack feedback while manual cropping.

我猜你是用双指手势来移动裁剪手柄的？

TalkBack 在拖拽操作期间无法提供清晰的反馈。

您希望获得哪种类型的反馈？每次移动或调整操作后应该发布哪些公告？

我找不到任何一款可以在手动裁剪时提供 TalkBack 反馈的编辑应用程序。

Yes, that’s correct — I’m using a two-finger gesture to move the crop handles.

During the drag operation, TalkBack currently provides no meaningful feedback, which makes it difficult for visually impaired users to understand what is changing on the screen.

Ideally, TalkBack could announce the current state after each adjustment, for example:

the position of the crop handle (e.g., “left edge moved”, “top edge adjusted”), or

the resulting crop area or size (e.g., width/height, aspect ratio, or relative position).

Even coarse or periodic feedback would be helpful, as it allows users to confirm that their gesture had an effect and understand the direction of the change.

I understand that many existing editing apps do not provide TalkBack feedback during manual cropping, but this still represents a significant accessibility barrier. Without any auditory feedback, drag-based cropping is effectively unusable for screen reader users.
