In my scenario, some user using Xiaomi Chinese MIUI ROMs device does not include PlayServices. And user installed the specific working GooglePlayServices manually from a third party Installer.
After Upgrade to the new MIUI version, that GooglePlayServices is not working anymore, but still exist in a user device.
In that case googleApiAvailability.isGooglePlayServicesAvailable(activity) still returns SUCCESS;
How can I check that installed GooglePlayServices is working properly or not?
    private fun isGooglePlayServicesAvailable(activity: Activity): Boolean {
       val googleApiAvailability = GoogleApiAvailability.getInstance()
       val status = googleApiAvailability.isGooglePlayServicesAvailable(activity)
       when (status) {
           ConnectionResult.SUCCESS -> return true
           ConnectionResult.SERVICE_DISABLED,
           ConnectionResult.SERVICE_INVALID,
           ConnectionResult.SERVICE_MISSING,
           ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED -> return false
       }
       return true
   }
Request to FusedLocationProviderClient or LocationManager
if (isGooglePlayServicesAvailable(this)) {
val task: Task<LocationSettingsResponse> =
    settingsClient.checkLocationSettings(mLocationSettingsRequest)
task.addOnSuccessListener(this) { response ->
    val states = response.locationSettingsStates
    if (states.isLocationPresent) {
        //Do something
        startFusedLocationProviderClientService()
    } else {
        Log.d(TAG, "startLocationUpdates: ${states.toString()}")
    }
}
task.addOnFailureListener(this, OnFailureListener { e ->
    when ((e as ApiException).statusCode) {
        LocationSettingsStatusCodes.RESOLUTION_REQUIRED -> {
            Log.i(TAG, "Location settings are not satisfied. Attempting to upgrade " + "location settings ")
            try {
                val rae = e as ResolvableApiException
                startIntentSenderForResult(rae.resolution.intentSender, REQUEST_CHECK_SETTINGS, null, 0, 0, 0,  null)
            } catch (sie: IntentSender.SendIntentException) {
                Log.i(TAG, "PendingIntent unable to execute request.")
            }
        }
        LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {
            val errorMessage = "Location settings are inadequate, and cannot be " + "fixed here. Fix in Settings."
            Log.e(TAG, errorMessage)
        }
        else -> {
            // For some device Technically GooglePlayServices is available but not functional
            Log.e(TAG, "startLocationUpdates: err ${e.message.toString()}", e)
        }
    }
})
  task.addOnCanceledListener(this, OnCanceledListener {
      Log.d(TAG, "startLocationUpdates: OnCanceledListener")
  })
  } else {
     //Non Play Services devices
     nonPlayServicesLocationManager()
 }
After a few minutes(3 minutes) later GoogleService returns as below:
