1. Checking basic notification settings

Start with the obvious: notifications may be disabled at the system or application level. In One UI there are two independent menus for managing alerts - in settings Android and in the shell Samsung. Skipping one of them is a common cause of problems.

Open Settings → Notifications. Here you will see three key sections:

• 🔔 Latest notifications — notification history for the last 24 hours. If the list is empty, the problem is global.
• 📱 Application settings — alerts are configured here for each application separately (for example, WhatsApp, Telegram).
• 🔕 Do not disturb —a mode that can block all notifications. Make sure it is turned off or configured correctly.

What is Doze Mode and how does it affect notifications?
