Yes. It's an Android thing. See this.

We have found the opposite - my Nexus gives "better" results than the client's Samsung tablet!

Could you elaborate on "connection priority" - is that an Android thing?

My impression is that Nexus phones prefer longer intervals, while Samsung phones allow shorter intervals. From Android 5 it has been possible to request a connection priority, if you use connection priority high I think you should get 11.25-15ms connection interval. You can test this feature with nRF Connect for Android, when you have connected click on the vertical ... and select request connection priority.

No - it is on tablets (mostly; and a few phones) that have been used throughout the project.

Yes, they do vary greatly.

Are you perhaps using a different phone or Android version? The supported Connection Interval (CI) and the number of packets sent per CI vary greatly, as presented in this post.
