Google limits the number of screenshots on the Play Store to 8 (it was 5 before) plus 1 video.
With these screenshots and media, you should give the basic overview of your app, show different
functionalities within your app, and basically sell your app.
-You should also check if Google has predefined resolutions for screenshots for different Android devices. You can find the latest information on this, on their developer page.
-Don’t have a complicated description on the listing page. Simple is better. Your screenshots
should be self-explanatory, enriched with some text, and refer to different points of your app.
- Keep in mind that the first image is the most important one and offers the user a great first visual
experience.
