Thank you Erel.
I intensively use anchor but never use designer script before.
This design work fine with all tablet used before (more than 10 different) with resolution from 1280 x 800 to 2560 x 1600.
For my test I use with variant I use designer script essentially to adjust font size.
Log(GetDeviceLayoutValues) return 1920 x 1104, scale = 2.0 (320 dpi) = value see with visual designer.
This is a big app (9 complex layouts), relatively old (6 yeras) and lot of view on each layout, so I had hope solution without redesign
