A significant confusion in the car audio market arises from unbranded, generic "Android head units." These are Chinese-made car stereos that run a full, open version of the Android operating system. Often, the build system used to create the firmware for these generic units is based on, or inspired by, the MediaTek ALPS platform (our first definition). Consequently, when such a unit boots up, its system information might show the manufacturer as "ALPS".

Often features unlocked bootloaders, making them popular with hobbyists for custom firmware modding.

When Google releases a monthly security bulletin, MediaTek issues corresponding ALPS updates. If your phone’s build contains ALPS.W10.20.P3 , an engineer knows immediately which CVEs (Common Vulnerabilities and Exposures) are patched and which are not. This led to the support of new touchpad

When Google releases a new version of the Android Open Source Project (AOSP) , chip manufacturers (chipset vendors) like Qualcomm or MediaTek write the foundational software layer to make the operating system talk to their hardware. This baseline software bundle is known as a .
