# First Steps with motorola phone & ThinkReality A3

This guide applies to motorola edge 30 pro and motorola edge+ phones.

Before using the A3 Kit for the first time, the motorola edge 30 pro (motorola edge+) needs to be up-to-date and there are several required apps that must be installed from Lenovo ThinkReality Cloud. These apps will be automatically installed once the phone is registered on the ThinkReality Cloud. Finally, a glass firmware update is also required; it will also be automatically installed at this time once the steps below are completed.

# Step 1: Unbox and Setup Phone

Follow the standard Android steps to set up the phone and connect it to a Wi-Fi network with Internet access.

# Step 2: Download All System Updates

Once the phone is setup, visit Settings -> System updates -> Check for updates to ensure that the mandatory updates have been downloaded and installed.


The correct phone versions differ slightly based on which version of the phone model that is available in region.

S1SH32.55-78-10 (motorola edge+)

# Step 3: Connect the A3 Glass and motorola phone

Connect one end of the USB Type-C cable into the slot on the motorola phone. Next, connect the other end of the cable into the cable connector slot on the headset.

# Step 4: Launch the Lenovo Universal Device Client (UDC) app

Connecting the A3 glass to the motorola phone for the first time will enable and launch the UDC app automatically.


Once the UDC app is enabled disconnect the A3 glasses. Reconnect the A3 glasses later in the setup procedure to receive any glass firmware updates.

# Step 5: Accept UDC Terms and Permissions (steps 1, 2, and 3 within app)

# Step 6: Scan the QR Code to Register the motorola Phone

Register the motorola phone by scanning this QR code:


If an error occurs in registration, this device may have been previously registered and your serial number may need to be cleared from the backend portal.

If that is the case, go to https://spaces.qualcomm.com/settings/ (opens new window), logging in if necessary. Follow the directions under section Serial Number of Phone and select "Clear My Registration" to submit your serial number for clearing. Once processed on the backend, an email will be sent confirming device clearing allowing for resubmission of the serial number, at which point repeat this step.

# Step 7: Accept App Install Prompts

Once registered, the following apps will automatically be installed on the motorola phone. Names may be similar and not exact in some regions.

  • A3 Home
  • Companion
  • App Space Service
  • Mobile App Launcher
  • AR Cast
  • Glasses Firmware 983


Make sure to accept all app install requests on the motorola phone. Additionally, some apps will request Display over other apps permissions. Note that these apps are part of Lenovo’s ThinkReality suite and are not used in actual Snapdragon Spaces development, but recommended for general device use.

Additional ThinkReality steps include being prompted to automatically open the Companion app when the glasses are connected, and going through on Onboarding Tutorial for the glasses. Again, (currently) these are related to the ThinkReality platform, which is separate from the Snapdragon Spaces platform and lives on the device in parallel (today).

A video tutorial about the ThinkReality Applications can be found here: https://support.lenovo.com/us/en/videos/nvid500337 (opens new window)

# Step 8: Disconnect and Reconnect A3 Glasses to trigger Firmware Update

If a firmware update is available for the A3 glasses it will be automatically deployed to the motorola phone and installed on the A3 glasses. See the Android notification bar on the motorola phone to see the A3 installation progress. The glasses need to remain connected to the phone for the duration of the firmware installation, they will reboot automatically once updated.

To get to glasses firmware D1028, multiple updates may need to be installed sequentially, such as D983 first and then D1028. If there is a pause in deployment or the glasses are disconnected during the upgrade, please visit the Lenovo Universal device client application and click on Check for update”. To monitor the download and installation swipe down on the phone to view notifications under Lenovo Universal Device Client


If a registered motorola edge 30 pro (motorola edge+) device is manually reset back to factory settings, there will be no way to re-register that device without contacting the Snapdragon Spaces Support Team. An error message indicating that the registration has failed will appear if the registration process is attempted. To avoid this error message, e-mail Snapdragon Spaces support directly using the previously provided support e-mail. The flashed device will be deleted by the Snapdragon Spaces team, and, upon confirmation of removal, the device can be registered again.

# Step 9: Setup Complete

The ThinkReality A3 should now be ready to use. Required Configuration for Spaces Developers

  • Phone Image: S1SH32.55-78-8 and above (motorola edge 30 pro) or S1SH32.55-78-10 and above (motorola edge+)
  • Glasses Firmware: A3_user_S1028001_2204241414_sdm710_postcs8

The Glasses firmware in its raw format is displayed at the bottom of the Lenovo Universal Device Client (UDC) application. Note that the glasses must be plugged in and fully connected in order for the glasses version to be displayed.

# Optional: Provide Phone Serial Number

If you would like to have the latest Spaces Services and Spaces Samples pushed to your device, you can submit your serial number and information for processing by our support team. (This is an optional step as these apps can be installed via adb commands by downloading the Unity or Unreal SDKs.)

To submit your serial number, follow these steps:

  • Upon review and processing, you will be notified via email once everything is completed and apps are deployed to your mobile device.

# Optional: Enable Developer Mode

This is a highly recommended optional step. When the ThinkReality A3 is connected to the motorola phone it will automatically start the Lenovo Companion application. To disable this:

  • Open the Companion application
  • Touch the three line icon in the upper left corner to bring up the sidebar menu
  • Select "Settings"
  • Slide down and under the "Developer's Settings" header, toggle the slider "Enable Developer Mode"
  • The Companion applicatoin will no longer start when a ThinkReality A3 is connected
