Making reminders reliable on Android

Barzaman schedules reminders on the phone with Android’s official alarm APIs. Some manufacturers, however, kill background apps or delay their alarms to save battery. This guide follows the manufacturer notes collected at dontkillmyapp.com.

Menu names vary by phone model and Android version. If you can’t find an option, type its name into your phone’s Settings search.

Step 1: core permissions (every phone)

1. Notifications (Android 13+): Settings → Apps → Barzaman → Notifications → on.
2. Alarms & reminders (Android 12+): Settings → Apps → Special app access → “Alarms & reminders” → Barzaman → allowed.
3. Battery optimization: Settings → Apps → Barzaman → Battery → Unrestricted (or “Don’t optimize”).
4. Full-screen notifications (Android 14+, for alarm style): Settings → Apps → Special app access → “Full-screen notifications” → Barzaman → allowed.

Step 2: manufacturer settings

More tips

• Do Not Disturb: alarm-style reminders pass through Do Not Disturb like an alarm clock; regular reminders follow your DND settings.
• Cleaning apps and “Close all” in Recents stop apps on some phones; locking Barzaman in Recents prevents this.
• System updates sometimes reset these settings; check again after one.
• Barzaman re-schedules reminders automatically after a reboot, a time or time-zone change, and an app update.
