I have been running lineageOS on my OnePlus 2. I liked it, but Lineage has stopped supporting my phone. There are two options that I have been able to find as replacements - postmarketOS and /e/OS. Any thoughts on those or other recommendation? Anything that gets security updates, is open source, and is functional meets my needs.
I highly recommend just going to the xdadevelopers forum for your device, and see what the most supported ROMs are. They'll all be AOSP-based of course, but many of them will have de-googled / de-play-store download options. Most importantly the most popular ones will always support all your phone hardware.
Can you provide a source for your dubious claims? Is this the "12yo p*jeet ROM" racist meme? Because I am an Indian, who has been enough on 4chan and reddit to know what this means.
