My glasses do not connect when I plug them into my phone - I get this a flashing icon

You have followed the following steps and understand how to boot the glasses - but you get a flashing error logo instead.


If you see this, then this indicates that there’s no supported device connected.
This is likely connectivity issue – disconnect USB cable and reconnect.
If it persists try a different high-quality USB cable


This Indicates that the connected device is missing software. Make sure that you've completed all the steps in the Spaces Setup-Guide. When you've registered you device and received notification that we've pushed software to your device, then when you plug in the A3 glasses there should be an update (or two) that gets pushed to your glasses. Use the Lenovo Companion to verify that you have correct version of the software installed (Step 10 on the Set-up Guide)



My headset is having the top issue where it shows the cable is the issue, but I've tried 4 different usb-c cables and even a thunderbolt 3 usb-c and i'm still having the issue. Tried plugging into both a desktop & the motorola phone.

The USB-C cable that comes with the glasses (with the 90° connector) should work. I would test it between two known-good devices and if it fails, then contact Lenovo. In the mean-time we've have good luck with any high-quality USB-C cable. Make sure that when you connect your phone to a PC using that cable you actually get a connection (both the phone and the PC will tell you it's connected). I've seen more phone connectivity issues than glasses connectivity issues.

 I'll try to get a few recommendations for replacement cables.

Hi Ron, Still having the issue with the cable (first image). Tried different cables and nothing changed, tried also the phone factory reset and nothing changed. I can use the glasses for example to control the camera of the 3d model viewer app coming from Lenovo, I can’t see the rendering in the glasses, but If I move the head while wearing the glasses, I can see the camera moving on the phone while the app is open. So it seems that the glasses communicate with the phone.

I'm also suddenly experiencing the first error (has been working fine up until now). Tried both the included cable and several alternates- the headset boots up and then begins flashing the first error image.
