Bug description

In the notification tray the count of signal message is always +1 because it is including "signal is unlocked".

This is also causing problem with notification sound in following scenario:

1. Unlock Signal and send message to someone.
2. Come out of signal and wait for someone to respond within the period when Signal is still unlocked.
3. When they respond 2 sounds are triggered within 1 second even though they sent 1 message.

This is observed after I upgraded to OneUI8

Screenshots

Even the notification sound that we get when we receive message is one or two more when we receive message when the phone is locked and sometime within few seconds if unlocked then I can hear one more sound.

Following image is "Sound History" from an app called "nice catch" under "Good Lock" by Samsung.

Device

Samsung S24 Plus

Android version

Signal version

7.62.0

Link to debug log

Start by reviewing the linked debug log and reproducing the notification tray and sound behavior using the listed steps on a Samsung S24 Plus with Android 16. Done means a received message contributes one notification count and triggers one sound, without counting the “signal is unlocked” notification.
