So my current phone is becoming more and more annoying to use (it’s more than 5y old) and I was doing more research on which phone to buy next. I realized that something escaped my initial analysis presented in this thread: if you buy a new phone, and install LineageOS or any other custom ROM for that matter, you lose your warranty. This means that the /e/ refurbished phones become slightly more appealing.
However, I checked Amazon (https://www.amazon.co.uk/s?k=galaxy+s7&rh=n%3A5362060031%2Cp_89%3ASamsung%2Cp_n_feature_eight_browse-bin%3A14210456031&dc&qid=1579358675&rnid=14210451031&ref=sr_nr_p_n_feature_eight_browse-bin_5) for S7s and they are considerably cheaper than the 280€ /e/ is asking, even refurbished ones.
I have more thinking to do.
