After mail read does notification remove from android

When you read an email on your Android device, the notification associated with that email is typically removed from your notification shade. This is because the notification is no longer needed once you've read the email.

Here's what happens behind the scenes:

1. When you read an email, the email client (e.g., Gmail, Outlook, etc.) sends a notification to the Android system that the email has been read.
2. The Android system updates the notification to reflect that the email has been read. This might involve changing the notification's text, icon, or other visual elements.
3. Once the notification is updated, the Android system removes the original notification from the notification shade. This is because the notification is no longer relevant or necessary.

However, there are some exceptions and variations:

• Some email clients might not remove the notification immediately after you read the email. Instead, they might keep the notification in the notification shade for a short period, such as 5-10 seconds, before removing it.
• Some email clients might use a different notification strategy, such as displaying a "read" or "seen" indicator next to the email in the notification shade, rather than removing the notification entirely.
• Some Android devices or custom launchers might have settings or features that allow you to customize the behavior of notifications, including whether they are removed automatically after being read.

In general, though, the notification associated with an email is typically removed from the notification shade after you read it, as it's no longer needed or relevant.
