I am using Google Analytics and I have seen that all the devices in the Cloud Test Lab are detected as "active users" and "new users" (which makes sense). Is there any way to detect this and do not count them ?
I see that they are not counted as installs in Google Play, so I would expect the same behaviour for Analytics.
It is possible to avoid this by uploading a different version to Alpha/Beta and Production with different tracking ids, but the Cloud Test Lab feature is much more powerful if the same Apk is promoted from Alpha/Beta to Production.
Depends on what you mean by "not count them". If these cloud visits are identifiable by source/medium or another unique parameter, I think best practice would be creating another view in which these visits are filtered out. Otherwise you could apply a segment to your standard view that excludes these visits.
