Hello,
I can provide you 7’’, 1920x1200 screenshots from a real device.
My device info: Google Nexus 7, android version 4.4.2, screen 7’’, 1920x1200.
Screenshots (9+, or up to 30, if you are interested) will be delivered very quickly, not later than 6 hours after awarding me a project and sending me the APK.
Best regards
