Lamtto RC23 Not Working? Fix Display, Lag, TikTok and App Issues (Full Guide)

When using the Lamtto RC23 CarPlay AI Box, you may occasionally encounter display or system-related issues. Most of these are not hardware defects, but rather related to system adaptation, settings, or connectivity.

This guide summarizes the most common problems and provides simple, practical solutions.


Display and Screen Issues

Screen Adaptation Issues

The RC23 is designed as an adaptive system, meaning its display depends on your vehicle's infotainment screen.

What to Check:

  • Ensure your car's main interface is displaying properly
  • Open a video and tap the screen to bring up the playback controls
  • If the progress bar and UI elements appear in full screen, the issue is not caused by the RC23 device

Blurry Video Playback

If video quality appears unclear, this is also related to screen adaptation and depends on your car's display resolution. Test the RC23 in another vehicle if possible and compare display clarity across different infotainment systems.

Floating Icon (Overlay) Issue

Some users may notice a floating icon on the screen.

How to Disable:

  • Go to Factory Settings
  • Enter password: 4545
  • Tap Other
  • Turn OFF the floating icon
  • Save settings

Lag or Slow Interface

If the system feels slow or unresponsive, try the following:

  • Check your phone's network connection
  • Clear cache on your phone
  • Restart CarPlay connection
  • Try using a different phone

System Settings and Function Issues

How to Change Language

If the system language is incorrect, scroll down the language list, find Italiano, press and hold it, and drag it to the top. The system will switch language accordingly.

How to Reset the Device

If you encounter system errors or app issues:

  • Go to Settings
  • Tap More
  • Select System
  • Tap Reset Options

Important: Do NOT enter Factory Settings, as the password is not publicly available.

Slow Response or System Delay

  • Go to Settings → Other → Feedback
  • Enter your issue (or leave it blank)
  • Tap Confirm
  • Copy the Case ID or take a screenshot
  • Send it to support for further analysis

The system will start compressing log files.

Unable to Update Apps

  • Open App Store or Google Play Store
  • Search for the app manually
  • Tap Install or Update

TikTok Not Found in App Store

  • Go to Settings → More → System → Reset Options
  • After reset, open the App Store
  • Search and download TikTok again

Final Thoughts

Most issues with the Lamtto RC23 are related to:

  • System adaptation with different car screens
  • App or cache conflicts
  • Network or device connection

These problems can usually be resolved with simple adjustments or resets.
