The biggest alternative to Android is iOS from Apple. But iOS is no big winner when it comes to privacy either. Here are a few Android OS alternatives that can really boost your mobile privacy:
LineageOS – A free and open-source operating system for phones and tablets based on Android.
Ubuntu Touch – A mobile version of the Ubuntu operating system.
Plasma Mobile – An open source, Linux-based operating system with active development.
Sailfish OS – Another open source, Linux-based mobile OS.
Replicant – A fully free Android distribution with an emphasis on freedom, privacy, and security.
/e/ – This is another open source project with a focus on privacy and security.
Purism is addressing the issue of mobile phone privacy by bringing out their own phone, called the Librem .
Happy learning!
