I’ve had good luck buying phones on eBay. I bought a OnePlus 6T last fall that was in box and practically brand new because the 6T has good Linux support, phone arrived and worked great. I just bought a OnePlus 6 because it too is well supported on Linux (postmarketOS) and doesn’t have as big of a notch, good condition but minor OLED burn in. Problem is that the previous owner didn’t realize that PIN lock remains over factory reset so it was locked. I managed to find an unlock procedure before the seller got back to me with the PIN and it’s working fine now (though I think I will stick with Android on this one after all).
