That’s so weird, doesn’t seem like a good business practice but hey, let’s get whatever we can out of them..lol shoot I should take my X before I sell it. Well actually I am selling it so I don’t care. Lol
And this is why I never buy used devices on third party websites or etc. like seriously if you’re selling it and can get the battery replaced for free go do it. I got my Note 8 battery replaced before I sold it
