In my Play Store experience, a modicum of trust is established merely over the icon. If I see an app and positively confirm that its icon is official and authentic, that's a good flag. If I search for something and I see a bunch of janky fake icons, then I avoid them all. Of course an icon is not the be-all-end-all; you need to check the publisher too, and reputable apps usually have Verified Publishers to go with them.<p>So that's why, even if your X app shows up in a search for the term "Twitter", if your app doesn't bear the officially-trademarked blue birdie icon, then everyone's going to squint and scoff at it, or not even notice it.<p>Awhile ago I was playing mobile games with a friend, and she has iPhone while I have Android. So part of the challenge was finding a cross-platform game. And many of them didn't have verified publishers or anything, so the best way to ensure that we both downloaded the same app was to show her the icon so that she could hunt for the same image in the App Store.<p>Icons are also becoming the default way of identifying apps on your system, too. While Android 11 still has text captions for icons on the Home screen, I find them superfluous. In fact, I've taken to creating folders and labeling them with several emoji, and no Latin text at all. I've also done this to my Bookmarks Bar: saves a lot of screen space!
