I thought I could deal with the Samsung crapware anyway, coming from iPhone and having used a OnePlus One with Cyanogen and later lineage... Boy, I was wrong, beautiful hardware for sure but the OS is utter garbage.
By garbage I mean: Bixby is unwanted and disabled, but it still pops up nearly constantly.. essential features of the phone require a samsung account, in an attempt not to sign up for it I get notified weekly that I must have one.. samsung programs will randomly notify me about random things that I have no interest in knowing about. Especially samsung pay- I DO NOT WANT AN OFFER ON COFFEE JUST LET ME USE YOU TO BUY THINGS. Upday has a pre-loaded list of the worst british newspapers, and insists on telling me about "breaking news" regarding a nice young american lady who is marrying one of our princes...
I miss my phone being in my control, and that's what everyone who was selling me on android was telling me was compelling about the platform.. But I had much more control of my phone when I was with Apple.
(And yes, I donated heavily to the LineageOS+S8 effort)
