Device freezes, followed by a black screen, with ADB unresponsive

Expected Behavior

The mobile device should be responsive.

Current Behavior

  • It has encountered a freeze sometimes.
  • Can't capture the logs through logcat as it failed to generate any output. Unable to access the shell too.

Steps to Reproduce

I am uncertain about the reliable reproduction steps for this issue, but in previous build versions, I have made the following modifications:

  • Disabled Dark theme
  • Disabled Ambient display
  • Disabled Notification light
  • Set Peak refresh rate: 90 Hz
  • Set Minimum refresh rate: 90 Hz

All other settings remain at default, without any additional modifications (such as Magisk). Subsequently, I leave the device idle for several hours, sometimes charging, sometimes not. When I attempt to wake the screen, it completely freezes.

Logs

My device encountered the freeze issue around 20:22 -20:25 AM GMT+8 on 20240216. My device has become entirely unresponsive; ADB fails to detect it, leaving me no choice but to perform a long press on the power button to initiate a reboot.

After rebooting, I attempted to capture the logs using the following command:

adb root
adb pull /sys/fs/pstore D:\Downloads\
adb logcat > D:\Downloads\issues.log
