I recently acquired the OnePlus phone, and immediately started digging into customizations. One of the features is Quiet Hours.
I didn’t realize it at the time, but Quiet Hours in CyanogenMod 11 u38+ breaks notifications on the OnePlus.
After some Googling, finally found the right post with directions that worked for me (and based on comments, many others).
https://jira.cyanogenmod.org/browse/BACON-6. Read the comment by Jake on Oct. 21, 2014 at 8:13 AM.
Here’s a summary:
- Turn Quiet Hours on
- Remove the Quiet Hours
- Restart phone
- Add Quiet Hours tile back
- Turn Quiet Hours off using the tile
You may safely remove the Quiet Hours tile after this and until this defect is corrected, don’t turn quiet hours on again.
