The official Android application store is Google Play, but Amazon, Aptoide, Mobogenie, GetJar, and Slide Me are some alternatives. Third-party app stores are more likely to contain malware and should be used with caution.
Google Play is the only official Android app store. Independent Android app stores include Amazon, Aptoide, Mobogenie, F-Droid, Slide Me, GetJar, and Samsung Galaxy Apps.
Security policies and the quality of user experiences for third-party offered apps vary, and some third party stores carry pirated games or malware. Because of this, installing an Android security app is recommended. In order to enable downloading from non-affiliated app stores, users navigate to Android's settings, then select the security menu, and tick the Unknown Sources option.
