Decreased BLE startScan detected devices on Android 5.0 Lollipop

Question

Short version:

In my tests with Android 5.0 Lollipop I have noticed android.bluetooth.le.BluetoothLeScanner detects BLE devices less frequently than Android 4.4 KitK

Answer 1

Beyond API 21 android uses SCAN_MODE_LOW_POWER by default. SCAN_MODE_LOW_POWER

Try SCAN_MODE_BALANCED and see if it gets better.
SCAN_MODE_BALANCED
