I recently sold a faulty Samsung Galaxy s22 Ultra to someone here on eBay, the phone had a cracked screen but was fully functional, it was listed as faulty and the listing was accurate, the phone was fully tested and factory reset, very well packed and sent to the buyer, they contacted me to say they got it and it kept boot looping when they turned it on and the motherboard is faulty needing a chip reballing, I explained that I found this very odd as all was fine before I'd packed and sent it, then they said the google account was removed as asked (Just in case there were login issues etc) I thought how do they know that if it was boot looping? so I asked, they then asked for a partial refund of £35 (It sold for £95) which I was reluctant to give as it was sold as faulty for spares or repair only, they then replied saying it was overheating, so again I informed them it was fine before , then they said the screen went corrupt,, I'd asked them if they'd tried replacing the screen, they said no and made out they had no idea? but they knew about mainboards and reballing? I mentioned this to them, as well as mentioning I am a retired electronics engineer so familiar with what it takes to reball and the equipment needed, they then said they just wanted it for their daughter who wasn't bothered about a cracked screen, I found all this rather strange, then they said they'd relist it themselves to try get some money back, I was frustrated with all the back and fore messaging as I knew the phone was fine apart from the damaged screen, I offered them to return it in the end but they wanted the partial refund so I gave in and refunded them the £35 they asked for wanting an end to it without having to got through a dispute etc then low and behold the phone appears on their eBay shown plugged into a tv fully working with a corrupt screen and another picture with the screen removed!! seems like they swapped the motherboard to me and put it in another phone that they sold just before they listed the one just mentioned having damaged the screen further by removing it! it all got rather confusing in the end hence giving in but to find the phone I'd sold them listed with the removed screen etc and all the excuses I feel conned and also feel like reporting them as eBay will have access to all the messages etc but is it worth the hassle? I don't know.
By the way I am a retired electronics engineer at 60 years of age due to ill health and although I know my stuff I know attempting to repair my own phone would not end well hence selling it and buying another second hand one because I'm a bit OCD and the crack in the screen was getting on my nerves.
