When I got my Z5 early this year, Z3 users were enjoying their concept ROM, then few months later, Z3 and Z2 users get to test Marshmallow Beta. So I suppose Z5 was too new and would not be suitable for the test and we would probably get to participate in testing Nougat (concept and/or beta). However, we see the beta programmes are offered to new phones like X and XP.
While I understand beta programmes are not meant to be stable and strictly for testing purpose only, but... why not offering them to Z5 (or Z4/Z3+) users?
