[BUG] [CLAUDE ANDROID APP] Image attachments silently not received by Claude in conversation

Summary

When I attach a screenshot from my mobile device and send a message in the
Claude Android app, the image doesn't reach Claude. The model responds as if
no image was attached — only the surrounding text comes through.

Repro

1. Open a conversation in the Claude Android app
2. Tap attach → pick a screenshot from camera roll / gallery
3. Send the message

Reproduces 2× today (2026-04-30) with two different screenshots.

Expected

Claude sees and references the image, same as on desktop.

Actual

Claude says no image came through; only the text reaches it. No error in the
UI — the image appears to upload normally and is shown attached in the sent
message bubble.

Workaround

Attaching the same screenshot from claude.ai on desktop works fine, so the
file isn't corrupt — issue is specific to the Android attachment path.

Environment

• Device: Pixel 10 XL
• Android version: Android 16
• Claude Android app version: 1.260423.20
