What exactly do you mean?

1. The screen turns on, you can turn off or snooze the alarm, but there's no sound and no vibration.
2. At the time the alarm should fire, there's no sound, no vibration and also the screen doesn't turn on. After unlocking the phone, there's a full-screen notification with sound and vibration.
3. Similar as above, but after unlocking the screen, there's a full-screen notification without sound and vibration.

you get a notification, but the sound/vibration doesn't come at all.

I've actually been testing this issue with timers and with the screen on, so this is not related to the screen being turned off or anything like that.

Please try with the screen turned off.

EDIT: okay, I edited all my comment.

Please try with the screen turned off.

only alarms have sound/vibration when the screen's turned off.

with the screen on, both of them lack sound/vibration.

are you able to reproduce that on silent mode?

[Aga-C]

I've tested on three phones (Android 10, 13 and 14, all non-rooted, on silent mode), and here are my findings.

For timers:

• On Android 13 and 14, no matter whether the screen is turned on or off, timers have sound and vibration.
• On Android 10 I can reproduce the same behavior as you have.

For alarms:

• On all three phones, sometimes, when the screen was turned off, alarms didn't have sound and haven't turned on the screen. I was mostly able to reproduce it with alarms set for a very short period of time (like two minutes from now). After turning on the screen, the full-screen notification appeared along with sound and vibration.
• On Android 13 and 14, when the screen is turned on, there's an alarm's notification, but there's no sound and no vibration.
• On Android 10, when the screen is turned on, there's an alarm's notification with vibration, but without a sound.
