Notification alerts are based on phone settings. Google added notifications for GPS in Oreo (android 8.0) and newer releases to help with user privacy management.
You can adjust the GPS notifications by following these steps:
Press and hold on the notification until you see an “All categories” option.
Click that.Scroll down the “Android system” notifications list and find GPS, then tap on GPS.
Tap on Importance and reduce it from “High” to “Medium” or “Low” (we recommend low)
Next, simply hit home and exit the settings menu and you’re all set.
Next time you run allGeo (or do anything that requires GPS such as Maps) you shouldn’t see or hear that annoying notification ☺ anymore.
Please let us know if this helps.
