Phone sees G2 over Bluetooth but the app shows error 920/521/818/103/015
Applies to Even G2.
These error codes appear when the phone and the G2 can see each other over Bluetooth but the Even Realities app cannot finish connecting. Even treats them together, with the same fix. Forget the glasses in the phone's Bluetooth settings, restart the glasses, and reconnect through the app. There are two restart methods: five quick taps on both temple TouchPads, or unplugging and replugging the powered case cable three times within seven seconds. A phone restart can also help.
Official steps
- Forget the glasses in phone Bluetooth settings, restart the glasses, and reconnect. To restart: tap both temple TouchPads five times quickly (you'll hear a prompt sound), or put the glasses in the powered case and unplug/replug the case cable three times within seven seconds.
- Restart your phone and try again.
- If it continues, contact support with the serial number, app logs with timestamp, and a screenshot of the error code.

Still not working?
If the error comes back, contact Even support with the serial number, app logs with a timestamp, and a screenshot showing the error code. Add your phone model and app version. The screenshot matters, because support needs the exact code you saw.
