Not reproducible with: 2021.3.51f1, 2022.3.61f1
Couldn’t test with: 2023.3.0a2, 2023.3.0a19, 2023.3.0b1, 2023.3.0b10(URP Global Settings throw an error that it’s the wrong version, no update available and creating a new Settings Assets doesn’t fix the error), 6000.0.0b11 (Project uses Input System specific features that are unsupported when downgrading package)

Testing environment: macOS 15.3.2 (M3 Pro)

Reproducible on:
VLNQA00629 - Galaxy S25 (SM-S931B), CPU: Snapdragon 9 Elite (SM8750), GPU: Adreno 830, OS: 15

Not reproducible on:
Galaxy Note 20 (Reporter’s)
VLNQA00525 - Galaxy S23 Ultra (SM-S918B), CPU: Snapdragon 8 Gen 2 (SM8550), GPU: Adreno 740, OS: 13

VLNQA00341 - Note20 Ultra 5G INT (SM-N986B), CPU: Exynos 990, GPU: Mali-G77, OS: 11

Notes:

Impossible to find regression due to URP Settings throwing unfixable compilation errors during downgrade
Skype was used as it had the closest functionality as calling the Phone Number (CQA does not have acces to testing devices with SIM Cards which are required for Phone Calls)
2021.3.51f1 and 2022.3.61f1 versions rather than freezing cannot play the Audio Source on first activation only on the second one
