Steps to reproduce
- Start T3 Code in remote/headless mode on an Ubuntu machine.
- Connect from a mobile phone browser using the LAN URL and pairing token.
- Open any chat/conversation.
- Try to attach an image from the phone.
- Observe that there is no visible upload/attach image button in the mobile web UI.
- Copy an image or screenshot to the phone clipboard.
- Tap the composer and try to paste the image.
Expected behavior
The mobile web UI should allow adding image context to a chat, either by:
- showing an attach/upload image button on mobile,
- supporting image paste from the mobile clipboard,
- or providing another mobile-friendly file picker flow.
This should work similarly to desktop web / desktop app image attachment support.
Actual behavior
On mobile Chrome, there does not appear to be an attach/upload image button in the chat composer. Pasting an image from the Android clipboard fails with a browser-level message:
Chrome unterstützt hier nicht das Einfügen von Bildern
English meaning:
Chrome does not support inserting images here
So image upload is effectively unavailable from the remote mobile session.
Impact
Major degradation or frequent failure.
This makes the remote mobile workflow much less useful when the user wants to give the agent screenshots, UI bugs, error dialogs, or other visual context while using T3 Code from a phone.
Version or commit
T3 Code 0.0.24 (latest npm release as of 2026-05-25), run via npx t3 serve --host 172.18.0.1 --port 35489 --no-browser
Environment
- T3 Code mode: remote/headless server
- Server OS: Ubuntu 24.04.4 LTS (x86_64)
- Server Node.js: v24.15.0 (via nvm)
- Client: Android phone
- Browser: Chrome mobile
- Connection: LAN URL with token
Logs or stack traces
No relevant server-side errors during normal operation. Both issues appear to be purely client-side/mobile web UI problems.
Screenshots, recordings, or supporting files
A screenshot shows the remote web UI opened in Chrome on Android. The composer has no obvious attach/upload image button, and Android/Chrome shows the message:
Chrome unterstützt hier nicht das Einfügen von Bildern
Workaround
Use desktop web / desktop app where image paste or image attachment appears to work, or transfer the image to another device first. No clean mobile-only workaround found yet.
