UE5.5 VR App on Meta Quest 3 Not Receiving Bluetooth Keyboard Input

Environment

• Unreal Engine 5.5
• Meta Quest 3
• Using the VR Template (OpenXR)
• The application starts directly in VR

Test Setup

• Input is handled using either Enhanced Input or Input Key events
• When a specific key is pressed, a corresponding number is displayed using the Text 3D plugin

Issue

• A Bluetooth keyboard is successfully connected to the Meta Quest 3
• The keyboard works correctly in system UI (e.g., search fields)
• However, no key input is received inside the Unreal Engine APK (in VR mode)

What I Have Tried

Android Manifest modifications

Added the following via ManifestRequirementsAdditions.txt:

<uses-feature android:name="android.hardware.keyboard" android:required="true"/>

Added the following via ManifestApplicationActivityAdditions.txt:

android:configChanges="keyboard|keyboardHidden|navigation"

Project Settings adjustments

• Disabled Enable Improved Virtual Keyboard
• Permissions added　android.permission.BLUETOOTH_CONNECT
  android.permission.BLUETOOTH_SCAN
  android.permission.BLUETOOTH_ADMIN
• Set Input Mode Game and UI　
  　Widget to Focus: NoneMouse
  　Lock Mode: Do Not Lock

Current Situation

• No key events (including basic keys like letters or numbers) are detected in the application
• This applies to both Enhanced Input and traditional Input Key events

Question
Is there any additional setup required for receiving Bluetooth keyboard input on Meta Quest 3 in Unreal Engine (specifically in VR / OpenXR)?
Or are there known limitations for keyboard input in VR mode on Quest devices?
