  • App not starting as XR (The phone screen shows content that's supposed to be rendered in the glasses)

They may be resolved with a simple reboot procedure:

  1. Reboot the glasses using adb reboot.
  2. Wait for the glasses to reconnect by checking if a device is connected to the hotspot on the phone
  3. Launch the app again and see if that resolves the issue

  • Snapdragon Spaces Services crashing
  • Two devices connected to hotspot (even though there's fore sure only one device connected)

They may be resolved with a simple reboot procedure of the phone and the glasses:

  1. Reboot the device using adb reboot.
  2. Turn on the hotspot on the phone
  3. Wait for the glasses to reconnect by checking if a device is connected to the hotspot
  4. Launch the app again and see if that resolves the issue

Advanced Setup​

Display the Hotspot Name​

The name of the Wi-Fi hotspot that started on the phone that the glasses connect to can be changed in a config file on the glasses. If the hotspot name doesn't match the config file, the glasses will not connect anymore.

Display the device's Wi-Fi configuration via adb:

  1. adb root
  2. adb shell cat /data/misc/wifi/wpa_supplicant.conf
  3. the line ssid="[hotspot name]" shows the name of the hotspot

Modifying the Hotspot Name​

Modify the device's Wi-Fi configuration via adb by pulling the file, modifying it, and pushing it back to the glasses:

  1. adb root
  2. adb pull /data/misc/wifi/wpa_supplicant.conf
  3. The file has downloaded from the device and can now be changed locally. Open it and change the line ssid="[hotspot name]" to the preferred hotspot name
  4. adb push wpa_supplicant.conf /data/misc/wifi/
  5. adb reboot
