How to check your Android version (and API level)

Swipe down and tap the gear icon, or open the Settings app.

Open About phone
Scroll to the bottom and tap About phone (Samsung: About phone > Software information).

Questions
What is an API level?
Each Android release has an API level number that apps use to say what they need. Android 10 is API 29, Android 14 is API 34, Android 16 is API 36.
Can I install an app made for a newer Android?
No. If an app needs Android 10 and your phone runs Android 9, the install fails. A system update, if your phone maker offers one, is the only fix.
