Alright, so the notification LED seems to have stopped working today for ALL incoming notifications. The LED still works when recharging the phone, but not for notifications. It's not blinking for Gmail, Google Messages, games, smart home apps, etc.
I'm fairly certain it was working just fine yesterday, too. Just started having issues today. There doesn't appear to be an SMMI test for the notification LED so I can't test to see if it's a hardware issue.
I've gone into the settings (Display ➡️ Light management ➡️ LED indicator), made sure the option was enabled. Disabled it, enabled it, no change. Rebooted the device a couple of times, no change.
Tried checking previous threads about this, seems this has been a common issue across multiple ASUS phones (both ROG and Zen), with no clear solution.
It's not a major issue to me. I've had several phones that did away with the notification LED completely, but it is a nice feature to have... And if you have it, it would be great for it to be working, ya know?
