The **Android Open Source Project** is an open-source mobile operating system led by Google which powers the majority of the world's mobile devices. Most phones sold with Android are modified to include invasive integrations and apps such as Google Play Services, so you can significantly improve your privacy on your mobile device by replacing your phone's default installation with a version of Android without these invasive features.

A few more tips regarding Android devices and operating system compatibility:
- Do not buy devices that have reached or are near their end-of-life, additional firmware updates must be provided by the manufacturer.
- Do not buy preloaded LineageOS or /e/ OS phones or any Android phones without proper [Verified Boot](https://source.android.com/security/verifiedboot) support and firmware updates. These devices also have no way for you to check whether they've been tampered with.

However, there are some security-related downsides to how F-Droid builds, signs, and delivers packages:
Due to their process of building apps, apps in the official F-Droid repository often fall behind on updates. F-Droid maintainers also reuse package IDs while signing apps with their own keys, which is not ideal as it gives the F-Droid team ultimate trust. Additionally, the requirements for an app to be included in the official F-Droid repo are less strict than other app stores like Google Play, meaning that F-Droid tends to host a lot more apps which are older, unmaintained, or otherwise no longer meet [modern security standards](https://developer.android.com/google/play/requirements/target-sdk).
Other popular third-party repositories for F-Droid such as [IzzyOnDroid](https://apt.izzysoft.de/fdroid/) alleviate some of these concerns. The IzzyOnDroid repository pulls builds directly from GitHub and is the next best thing to the developers' own repositories. However, it is not something that we can fully recommend, as apps are typically [removed](https://github.com/vfsfitvnm/ViMusic/issues/240#issuecomment-1225564446) from that repository if they are later added to the main F-Droid repository. While that makes sense (since the goal of that particular repository is to host apps before they're accepted into the main F-Droid repository), it can leave you with installed apps which no longer receive updates.

That said, the [F-Droid](https://f-droid.org/en/packages/) and [IzzyOnDroid](https://apt.izzysoft.de/fdroid/) repositories are home to countless apps, so they can be a useful tool to search for and discover open-source apps that you can then download through other means such as the Play Store, Aurora Store, or by getting the APK directly from the developer. You should use your best judgement when looking for new apps via this method, and keep an eye on how frequently the app is updated. Outdated apps may rely on unsupported libraries, among other things, posing a potential security risk.
