@debby Well, I main LineageOS (No MicroG, Ungoogled), simply because it's one of the rare phones that are officially supported. (I use a Sony Xperia XA2 Plus).
I might explore more ROMs in case I really find them awesome.
I mostly use a phone because I'm kind of "addicted" to technology and stuff like that. :P
I use apps such as PipePipe (NewPipe fork), SimpleX, FluffyChat, Moshidon, Droid-ify, etc.
I don't emulate ROMs, so far I only emulate old Windows environments (98/WXP/Vista/7 & Betas) for experiments and fun stuff, and artistic malware making.
Also I congratulate you for being very focused on your privacy and freedom.
