Update Android Mobile in few seconds step by step
To update your Android mobile phone, follow these steps
Make sure your phone is connected to a Wi-Fi network, as updating over a cellular connection may incur data charges.
Open the Settings app on your phone.
Scroll down and tap on "Software update" or "System update." The exact wording may vary depending on your device and Android version.
If an update is available, you should see a notification with information about the update, including the version number and size of the update. Tap on "Download and install" to begin the update process.
Your phone will download the update and then install it. This process may take several minutes.
Once the update is complete, your phone will restart and you'll be running the latest version of Android.
Note:
If you don't see an update available, it's possible that your device is already running the latest version of Android. You can also try checking for an update by going to the manufacturer's website and downloading the update from there.
