Specs from gsmarena:

Pixel 9
Android 14, upgradable to Android 15
Google Tensor G4 (4 nm)
Octa-core (1x3.1 GHz Cortex-X4 & 3x2.6 GHz Cortex-A720 & 4x1.92 GHz Cortex-A520)

Pixel 10
Android 15
Google Tensor G5 (4 nm)
Octa-core (1x3.1 GHz Cortex-X4 & 3x2.6 GHz Cortex-A720 & 4x1.92 GHz Cortex-A520)

The issue was introduced in Dec 2024 Android 15 update, affecting all Pixel devices that run Android 15
