You'll want the version number when reporting a bug, checking whether an update has arrived, or matching an APK to what you already have.
From Settings
- Open Settings > Apps.
- Choose the app.
- Scroll to the bottom of the App info screen. The version is listed there. On some Samsung phones it's near the top under the app name.
Shortcut: press and hold the app icon, then choose App info.
Inside the app
Most apps show their version under Settings > About or Help > App info. In WhatsApp, it's under Settings > Help > App info. In Firefox, it's under Settings > About Firefox.
From Google Play
Open the app's Play listing, scroll to About this app and press the arrow. The version shown is the latest one available for your device, which may be newer than what you have installed.
Version name and version code
Android apps have two version values. The version name (such as 3.2.1) is what you see. The version code is a number that increases with each release and is what Android uses to decide whether an APK is newer. You can't install an APK with a lower version code over a higher one.
