There are two reasons you should update the software for your phone and applications.
The first is so you will be able to experience new features that are added to the device or applications.
The second is to fix bugs or patch security issues, which is a major reason to update your software.
Updating an Android device is a easier than you think. Just follow the steps below and you’ll have the latest and greatest user interface from your developers in a jiffy.
Lets go into updating your phone’s software first.
1. Make sure your device is connected to Wi-Fi
You’ll need Wi-Fi to update your device because you shouldn’t waste your data to update the software as it could possibly empty it.

Go to settings, then tap on the Connections button and tap on Wi-Fi button and connect to your Wi-Fi.
2. Tap Check for Updates.
The device we have is a Samsung device, so after you have connected to Wi-Fi just scroll down the settings menu until you see Software update button.
You can also set the software updates to happen automatically whenever you are connected to a Wi-Fi connection.

Then, click on download and install. After that just wait for the device to automatically restart with the new software.
For other Android devices, depending on the OS, you’ll see Install Now, Reboot and install, or Install System Software. Tap it. Your phone will reboot.
Update Applications
Now lets update the applications on your Android device. You can do it manually or have the apps update automatically.
1. Manually update your apps
All you need for this is Google Play Store.
From the Play Store home screen, tap your Google profile icon on the upper-right hand corner.

Tap Manage apps & device, then you can either tap individually installed apps or tap Update All to download all available updates.
2. Automatically update your apps
From the same home screen, tap on the Settings button, then Network preferences button.

Then select one of the following to set up your auto update.
- Over Wi-Fi only
- Over any network
Data charges may apply.
After that you shouldn’t have to think about manually updating your apps whenever there is an update, unless the auto-updater doesn’t work for some reason (which is often).
