Screen dimming issue on the Fairphone 4
Basic info
- Device: Fairphone 4
- CalyxOS version: 4.11.3
Brief description of the issue
The screen's brightness drops to zero when the phone's temperature exceeds 43C. This is a known problem with the Fairphone 4 that affects Fairphone OS as well. It is NOT a CalyxOS bug.
Fairphone should be fixing this really annoying problem but they haven't done so in months for some reason, and a lot of people are starting to get really cheesed off with them.
I'm opening this bug report following a suggestion from Perzarys on the CalyxOS Matrix channel who reckons Calyx might want to do something about it on the basis that it might just be a simple misconfigured system file. See this link for details:
Steps to reproduce
Put the phone in bright sunlight, wait for the screen to turn completely dark when the phone is warm enough.
Expected result
The screen should dim slightly to help the device not overheat.
Actual result
The brightness drops all the way to 0.
Logs (if available, they make fixing much easier)
