Could you try disabling additional features when building your ProximityObserver object? There are two of them enabled by default - Telemetry scanning, and Estimote Secure Monitoring. If you don't need to use them, you can disable them like this:
proximityObserver = ProximityObserverBuilder(applicationContext, cloudCredentials)
...
.withEstimoteSecureMonitoringDisabled()
.withTelemetryReportingDisabled()
...
.build()The above should reduce the number of BLE callbacks being registered in OS, thus reducing the possibility of Scan error 2.

Prerequisites
Basic information
Estimote SDK version: 5.0.0
Android devices affected: Xiaomi Redmi Note 4
Android OS version affected: 7.1.1
Beacon hardware version: G1.12
Description
[Description of the issue]
I'm getting an Exception that crashes the App when starting to scan for beacons. For some reason this happens mostly on the listed devices, but it is also possible to trigger on other devices by turning off and on the Bluetooth before and/or after the scanning starts.
extra information about this issue, if i put the code in the main activity, it doesn't crash the application and i got the exception in withOnErrorAction, now we had to configure the scan in a service, because we want to be running in background whether the application is running or not. Because of this change the entire application crashes, that's not what i've expected.
(Optional) Steps to reproduce:
There are no several steps, just one, trying to configure the beacons as the downloaded example.
Expected behavior:
Start the scanning?
Actual behavior:
Crashes with exception.
