I found a post from a few months ago saying someone managed to get LineageOS on it, which is interesting but it's the only real lead I've found so far, and I don't want to risk bricking my only phone for. It's a shame there doesn't seem to be a lot of support for this model though. I don't have a lot of money to spare to buy a new phone specifically to degoogle, but I might have to end up buying one. I could probably get a cheap refurbished one from one of the popular privacy os's for daily use and keep this samsung one for stuff that I might still need google for.
