What users are saying

1. It crashes more often then it loads the damn animation and it requires more resouces than any other app on my phone.It's good but one problem, for the new brand catalogue it doesn't have an English version.

2. I should also be able to look at a static model that I can tilt, pan, and zoom to see the detail the way I want to see it, not be forced to watch an animation.Good concept, terrible execution.

3. You need to have a way for the user to select which model they want to look at BEFORE the loading screen for the animation.

4. 3D models are great and fantastically designed, there are no problems in loading, even if little child holds huge tablet in his small hands and shakes it ,- there are no problems at all.

5. Needs a predownload feature as the constant loading bars are a joke, could also stand to show the actual file size and current speed.

6. Tried the other countries / English version and it works but there's no available catalogue in English... I also have a screenshot of the window when the app blocked but don't know how to upload it.Its an ok app.

7. And when (presumably it's trying to load? showing the Lego piece that slowly fills solid white)) It doesn't actually ever load anything.

8. Randomly scrolling through a theme, waiting for the loading bars, hoping to find something of interest is just a poor experience.

9. In the non-AR mode you can tilt but there is no way to pan so builds extend off to where you cant explore them, but even if you did they automatically move on to the next with no way to pause or do it manually.I had to uninstall the app due to no catalogue present after the update.

10. Suggestion: give the user the option of the fun animation (which you are doing) and the actual size of th set.

11. Like what the others have commented, let the user swlwct which model/set they want to preview before loading.

Steps to Troubleshoot & Fix LEGO Issues

1. Fix LEGO Not Working/Crashes/Errors/Unresponsive & Black/White screen:


  1. Restart LEGO: Restarting the app will resolve most errors.
  2. Update the LEGO App. Here is how:
    1. On Android goto PlayStore » Search for "LEGO" » Open LEGO® 3D Catalogue » click "Update".
    2. On iPhone, goto AppStore » Your profile » Available Updates » Check for LEGO » click "UPDATE".
  3. Clear LEGO® 3D Catalogue app cache: Clearing cached data will force your app to retrieve the latest data directly from LEGO servers.
    1. On Android, goto Settings » Apps » Select "LEGO® 3D Catalogue" » click Storage » click "Clear Cache".
  4. Check LEGO app permissions. If any of these permissions required to use your device's features are disenabled, LEGO might not work.
  5. Uninstall and reinstall LEGO. If nothing else has worked, completely uninstall LEGO then reinstall.
  6. Restart your device. Last, restarting your device can often clear most problems causing LEGO not working


2. Fix LEGO Server issues & Internet Connection


  1. Check network connection: An unstable Internet will make LEGO be unable to connect to it's servers. Ensure your wi-fi is working then restart app.
  2. Disable VPN: VPN can cause connection errors and lead to LEGO not working. Make sure all VPNs are off
  3. Enable background data: When Background data is turned off, LEGO may not be able to connect to the Internet when running in the background.
