I’m getting on very well with the Samsung Galaxy Tab A7, on which I run LineageOS; although a later model or something from the S-series may be more performant. I wrote this blog post about it.
I love LineageOS, but on this machine the bootloader cannot be re-locked and there will probably be someone about to reply to this comment explaining why LineageOS is insecure or whatever. Also, Samsung devices require that you have a Windows PC in order to flash ROMs, as you have to use Odin instead of fastboot
.
Also, it’s worth noting that, while /e/ is slightly superior from a privacy perspective, it is potentially less secure, as it sometimes takes months for the team to apply patches from upstream. Lineage, meanwhile, only takes a few days or weeks.
It possibly does work under Wine, but I didn’t want to risk soft-bricking my tablet (which happened anyway, but that was because I didn’t let the download finish before flashing).
