It has a completely FOSS version that is available on F-droid. It also implements a pin which signal removed for convenience.
Its not available for ios
Yeah I know it’s not on iOS I still love Android so I try to stay up to date on Android as well even not having one. My iPhone is paid for by work so I just don’t complain .
For android Lineage os the best with F-droid as a app store.
Many will disagree with me but Lineage os has the best support and is updated once a month. None of your privacy ROMs can compete with that
Yeah but Linage OS does not relock the bootloader for extra security so if you lose physical access to your phone it is now vulnerable.
