Android Question Please scrutinize my variant resolutions

[Scotter]

PHONES
Galaxy II: 480x800 = 240x400
Pixel 2XL: 1440x2880 = 320x640 or 720x1440?
and for landscape, I assume I merely flip x and y?

TABLETS
Amazon Kindle Fire: 1024x768 = 512x384
Galaxy Tab 10: 1280x800 = 640x400
Galaxy Tab S4: 2560x1600 = 1280x800

Wrong approach. The fewer variants the better.

Start with a single variant and use anchors and designer script to build a flexible layout.

Reduced to 3 total variants. I'm starting to think the "this app is not compatible with your device" message may be caused by something else.
