If you are receiving "Foreground Service Channel" notifications on your Android mobile device, this is because you have the Background Syncing feature turned on. Background Syncing is automatically enabled when syncing a new Bluetooth Low Energy (BLE) diabetes device with Glooko. The Glooko app conducts frequent BLE scans in order to detect a sync initiating from a Bluetooth meter. This process occurs in the background and causes no disruptions to your device usage.
If you would prefer not to see "Foreground Service Channel" notifications, simply tap Turn off notifications at the bottom of the notification window.
If you would like to turn off Background Syncing altogether, see How do I disable Background Syncing? (Android)
