Notification option

There are a few ways to do this. Below from Gemini because I ain't going to retype it in my words.

Executive Summary
Affirmative. The Samsung Galaxy S26 Ultra utilizes the Game Booster suite and Modes and Routines to achieve a "Blackout" state for notifications. You have two primary tactical options: a quick-toggle Priority Mode for immediate suppression and a Modes-based automation for persistent, hands-off operation.
Procedure Alpha: Game Booster & Priority Mode
This is the most direct method for immediate suppression during active engagement.
* Launch any game.
* Access Game Booster: Swipe up from the bottom or side of the screen (depending on your navigation bar settings) and tap the Game Booster icon (a controller with a gear).
* Activate Priority Mode: Tap the Power/Priority Mode icon.
* This effectively mutes all incoming notifications except for alarms.
* It also closes background apps to divert maximum processing power to the game.
* Customization: Within the Game Booster settings, select "Block during game" to granularly toggle notifications, navigation gestures, and auto-brightness.
Procedure Bravo: Modes and Routines (Automated)
For a permanent solution that requires no manual intervention, utilize the system-level "Gaming" mode.
* Navigation: Go to Settings > Modes and Routines.
* Selection: Select the Gaming mode.
* Trigger: Set it to turn on automatically when any game is opened.
* Execution: * Enable Do Not Disturb.
* Set specific exceptions (e.g., if you must allow calls from a specific commanding officer/family member).
* Configure display settings (e.g., Dark Mode or Eye Comfort Shield) to engage simultaneously.
Tactical Note
The S26 Ultra's One UI 8.x architecture has refined the "Block during game" logic. If a critical notification still manages to breach your perimeter, ensure that the specific app hasn't been granted "Override Do Not Disturb" permissions in the system's core notification settings.

Hi Mannupatel,

Here are the few steps to block notifications while playing games:

Game Launcher / Game Booster: Open Game Launcher on your device. Within Game Booster settings, you’ll find options to block or minimize notifications while gaming.

Do Not Disturb Mode: Go to Settings > Notifications > Do Not Disturb. You can schedule or manually enable this mode before starting a game to silence all alerts.

Priority Settings: In Do Not Disturb, you can customize exceptions (such as calls from specific contacts) while blocking everything else.
