UsbGps4Droid
APK
UsbGps4Droid is a USB GPS provider for the Android operating system, providing GPS support for devices running Android 4.0 and above. The application provides location updates to Android which allows devices without an internal GPS to still use applications which require GPS (such as OSMAnd, Google Maps and log tracking software). I use this USB GPS with my Android Tablet Headunit, because the internal GPS does not work reliably. I have a main controller which automatically starts this application's background service when my car starts. The application is designed to work with any SiRF USB GPS device, however it has been tested as working with GlobalSat BU-353-S4 and a device based on the UBLOX LEA-M8P chip.

Vanced microG
APK
microG GmsCore is a FLOSS (Free/Libre Open Source Software) framework to allow applications designed for Google Play Services to run on systems, where Play Services is not available.This fork tweaks MicroG to be usable by applications that require Google authentication such as Vanced.Notable changes:No longer a system appPackage name changed from com.google.android.gms to com.mgoogle.android.gms to support installation alongside the official MicroGRemoved unnecessary featuresRemoved all permissions, as none are required for Google authenticationNote: microG (and so this fork of it) provides FOSS replacements for proprietary libraries in order to make apps which depend on such work. So a scanner will find the names used by those original, proprietary libraries as if they were there (which is how the apps needing them find them). Still the app won't be marked with the corresponding AntiFeatures, as those would apply to the original libraries only. NonFreeNet is still applied for Google authentication. Tracking is not, as Firebase Analytics here is just a stub (an „empty shell“ without functionality).
