I’m on iOS so I don’t think that’s supposed to happen. Definitely wouldn’t be the first time Android gets the shaft in terms of app quality from large companies. Looking at you Google whose iOS apps are better than their Android apps for some reason.
Perhaps iOS doesn't allow it. It's a valuable "bug" for Instagram, so they have no incentive to fix it. Otherwise the app is relatively bug free, and this issue has existed for years, so I'm not giving them the benefit of the doubt. Facebook absolutely doesn't deserve it.
I've seen it on multiple android devices. But even if only one tap on the search bar is necessary, it's still an antipattern, as the user clearly wants to search, and the keyboard should come up right away. Recommendations and suggestions should not be conflated with search, or at least shouldn't override search.
