“Pill reminder not working Android” is often battery optimization, not the app logic. Mediva One requests exact alarm capability where the OS allows so dose times fire on schedule, and reschedules after reboot via broadcast receivers.
Checklist
- Allow notifications for Mediva One in system Settings
- Disable battery restrictions / “optimize” for the app (Samsung, Xiaomi, etc.)
- Confirm Do Not Disturb exceptions if you use DND at night
- After OS updates, open the app once to refresh schedules
- Test with a non-critical reminder two hours ahead before trusting critical meds
Caregiver pushes
Local alarms wake the patient; remote caregiver alerts need network and OneSignal permission on the helper phone separately.
Manufacturer-specific tips
- Samsung: disable sleeping apps for Mediva One
- Xiaomi / Oppo: autostart and battery “no restrictions”
- Pixel: check notification channel importance is not silent
