Turn Off Notifications for Individual Apps auf Realme
Realme UI groups every installed app under one notification manager, so you decide per app whether alerts show up at all.
This matters when a single app sends constant promo pushes or duplicate alerts while other apps behave fine. Turning off system-wide notifications would silence useful apps too, so the per-app switch is the more precise fix.
Where to find the per-app notification switch
Open Tap on Settings ➔ Tap on Notifications & status bar ➔ Tap on Manage notifications ➔ Choose an App ➔ Enable or disable Allow notifications.
Disabling Allow notifications blocks every alert from that app, including sound, badge, and lock screen previews. Leaving it enabled still lets you fine-tune individual notification categories inside the same app entry, if the app offers them.
If notifications still pop up after disabling them here, check whether the app has its own in-app notification setting overriding the system control.
