2. Build the Player
3. Create a server and host the build (e.g. using the “python3 -m http.server” command)
4. Connect to the hosted build using a mobile device
5. Observe the Player

Expected result: A blue screen is displayed
Actual result: A black screen is displayed

Workarounds:
- Change the Color Space to Gamma
- The user stated that enabling the Show Splash Screen setting also prevents the issue. The CQA did not observe this behavior

Notes:

- Reproducible with these browsers: Chrome, Firefox. Could not test with Opera (“code 404, message File not found” error when connecting to the server)
- Not reproducible with a blank Built-In RP, 3D URP, or 2D URP project

[WebGL] [Android] Black screen on some Android devices when "Show Splash Screen" is disabled in the Project Settings

Resolution Note:

This is a duplicate of the issue that causes a black screen when the splash screen is not used with URP with linear color. The fix will be released with that issue.

Adding here as well we've experienced a similar report from a Samsung S10+ with a Mali GPU when we've used 2022.3.16 and 2022.3.44 so it seems to have been a problem for quite some time

A seemingly identical issue is also reproduceable on Lenovo 300e Yoga Chromebook Gen 4.
GPU: ANGLE (ARM, Mali-G52, OpenGL ES 3.2)

The game is visible in this case until the user toggles to full-screen. Then it goes black.

Switching to Gamma solves the issue on this device.

Enabling Show Splash Screen doesn't solve the problem. However, the user CAN toggle to full-screen mode if they do it while the splash screen is showing. Then once they toggle out of full-screen it goes black. And if they wait to go full-screen until after the splash screen, it also goes black.
