Yes. You can’t stop Android from catching up on missed notifications after boot, but you can throttle which apps are allowed to spam you at startup, and delay or group most of them so only the important ones appear immediately. 1. Turn off notification spam from low‑priority appsOn your S‑series tablet:Go to Settings → Notifications → App notifications. Sort by Most frequent or Most recent (if available).For any apps where you don’t need instant alerts (shopping, games, social, cleaners, etc.), switch to:“Silent” (no sound, shows quietly in the shade), orTurn off specific categories (e.g. “promotions”, “offers”, “tips”) while keeping important ones. That way, when the tablet boots, only genuinely important apps will ping you audibly or visibly.2. Use notification categories inside chat/email appsApps like Gmail, Outlook, WhatsApp, Telegram, etc. let you split notifications by type. Long‑press a notification from one of these apps → Settings.Disable or set to silent the categories you don’t care about (promotions, “updates”, “marketing”), leaving only direct messages or primary mail as alerting. This massively reduces the “flood” without turning the app off completely.3. Use Do Not Disturb for the first minutes after boot (optional)If most boots happen in the morning:Set up a Do Not Disturb schedule that keeps the tablet quiet until a time you choose, so the catch‑up flood doesn’t buzz/flash at you. You can still manually pull down the shade and see notifications, but they won’t all make sounds or pop up at once.4. Avoid unnecessary auto‑start/always‑on appsSome apps constantly wake at boot and refresh to generate notifications. Uninstall or disable any you don’t use.For apps that you only need occasionally, sign out or disable their background refresh if they offer that option.If you tell me which tablet model and which apps are the worst offenders (e.g. Gmail, Outlook, Facebook, a game, etc.), I can walk you through exact category settings to keep the useful alerts but stop the startup flood.
