Android devices come with a built-in app store that lets you download and install apps from the Google Play Store. However, there are other app stores available on Android devices, such as the Samsung App Store and the Amazon Appstore. To find hidden apps on your Android Galaxy S5, first open the Settings app. From here, tap on Apps. This will display all of the installed apps on your device. Next, scroll down and tap on Unknown Sources. This will allow you to install apps from outside of the Google Play Store. Tap on OK to confirm your decision. Now, search for an app that you want to install from outside of the Google Play Store. For example, I searched for “Uber” and installed it from the Samsung Appstore. Once you’ve found an app that you want to install, tap on it to open its details page. Next, tap on Install to start installing it onto your device. ..
