Android: The Recents menu, introduced in Lollipop, is a handy way to jump to a previous app. If you turn Developer Options on, you can also use it to jump to an app's info page, where you can force stop or uninstall an app.
Developer options are a hidden set of tools that are disabled by default in Android. While most people don't use them, you might have turned them on if you've ever tried to use ADB or fastboot. To enable Developer options, follow these steps:
- Open the Settings app.
- Open About Phone.
- Tap "Build number" several times, until a notification says you're a developer.
Once developer mode is enabled, you can use the Recents menu (accessed by tapping the multitasking button) to jump to an app's info page. With the Recents menu open, simply long-press the app's icon. As Android Police notes, if you're currently using Marshmallow and have any accessibility service (like Lastpass or Pushbullet) active, you can just tap the icon, instead of long-pressing it.
