To turn updates on or off, follow these steps:

1. Open Google Play.

2. Tap the hamburger icon (three horizontal lines) on the top-left.

3. Tap Settings.

4. Tap Auto-update apps.

5. To disable automatic app updates, select Do not auto-update apps.

6. If you want to instead auto-update apps only when you're connected to a WiFi network, tap Auto-update apps over Wi-Fi only in the same pop-up.

Android also lets you choose which apps you want to update automatically.

1. To turn on auto-update for any app, go to the app page in the Google Play app.

2. Tap the three vertical dots in the top right.

3. Check Auto-update.

This way, you can disable automatic updates and still keep chosen apps ready with the latest versions.
