Samsung Galaxy S4: How to Install Apps from Unknown Sources (.apk File)

Most of Android phone users(including with the Samsung Galaxy SIV users) usually install apps from Google Play Store which is the official market for all Android phones. To be able to access Play Store, you need to have an active Google account. As the official market, Google Play Store provide their users with tons of apps that you can choose which one that suit your need. But, it will be better if you read the app's review first before installing the app to make sure that the app has a positive review and less complaints/errors.

Nevertheless, though the Play Store has lot of apps, in some cases you may want to install certain app from other sources than the Play Store, for instance when the app is no longer available in the Play Store or you can't find any alternative app for the app you're looking for in the Play Store. Luckily, in Android, there's an option which will allow you to do so.

How to install .apk file?
An app from unknown sources usually has .apk extension. Well, here the steps to install it:

1. Go to Settings.
2. Tap More tab.
3. Tap Security.
4. Scroll down to find Unknown sources, and then tick the box next this option to enable it and then tap OK button to confirm enabling this option.
5. Tick the box next to Verify apps to allow your phone to block or warn before installing apps that may cause harm.
6. Now, you're allowed to install app from sources other than the Play Store. You can do so by downloading a .apk file of certain app through Browser app into your phone. (In this case, I'm using the stock Internet browser app to download calculator with percent.apk from appsapk.com).
7. Once the downloading process is completed. Open My File app and then navigate to the .apk location (usually all downloaded files will be saved in the Download folder in the phone storage)
8. Tap .apk file you've just downloaded.
9. Tap Install button.
10. Tap Accept button.
11. Once the installation process is completed, you can open the app and use it.

If your phone is encountering error after you installed a .apk file then it will be better for you to uninstall the app to fix the problem. So, have you ever installed a .apk file in your phone?
