I have an out-of-warranty Fairphone 2 with a faulty power button. It can still be turned on using the button on the side of the phone (ie with the case and edging removed) but it’s increasingly flaky. To get a new core module isn’t cost effective for me. The rest of the phone works without a problem. Battery health 82%. Happy to send the phone (with case and edging) to anyone in the UK who wants it for spare parts (or any other purpose!), for the cost of postage.
I have sent you a DM!
