Diagnostics & Support

ChannelUP includes built-in diagnostics tools for troubleshooting issues.

Debug Overlay​

Open the diagnostics overlay from the settings menu. It shows:

  • App version and webOS version
  • Tuner information — model, firmware, device ID
  • Signal quality for the current channel
  • Active tuners — which tuners are in use and what channels they're tuned to
  • Storage usage — localStorage and db8 stats
  • Performance metrics — guide load times, render times
  • EIT scanner status — scan progress, event counts, cache age

Sending a Diagnostic Report​

If you need support, you can send a diagnostic report directly from the debug overlay:

  1. Open the Diagnostics screen from the settings menu.
  2. Select Send Diagnostic.
  3. Review the consent screen, which lists the categories of information to be sent.
  4. Select Confirm & Send. A QR code appears after a successful submission.
  5. Scan the QR code with your phone to open the optional feedback form.
  6. Add a short description of the issue and, if you want a reply, your email address.

The report may include App and playback state, the current channel and stream URL, HDHomeRun details, TV model and firmware, LGUDID and serial number, local network information, tuner status, signal information, EPG/subtitle diagnostics, and the names and sizes of local storage entries. Some fields are stable device or network identifiers and may be personal information when linked to you.

Submitting a report is optional. Reports and attached feedback are processed through LevelIT UP's Cloudflare-hosted support service and are scheduled for deletion after 30 days. The feedback form records the description you provide, an optional email address, submission time and browser user agent; Cloudflare also processes your IP address for rate limiting and Turnstile verification.

See the Privacy Policy for the complete disclosure, retention details and information-request options.
