Ask HN: How to secure an old android phone that is no longer supported
I am still stuck on Marshmellow and find myself increasingly frustrated by the lack of updates especially when reading about the recent issues on the September Android Security Bulletin [0]
I am considering LineageOS but I think I am done with android in general and I do not think postmarketOS is developed to a point where I could make phone calls and texts or participate in data plans.
my preference in the immediate near future is to keep my phone without changing OS but know I will switch to postmarketOS type solution as soon as it is ready for general use (phone/data/work with carrier cell towers)
