Given my experience with my Galaxy Fold 2 and Samsungs terrible customer service I am done with the fold devices and probably all Samsung devices. When I look on ebay at used Galaxy Fold 2s and 3s, I see that many have the same issue I did regarding the phone not folding open fully flat. Samsung will not be able to fix it and will do all they can to avoid sending out a replacement by making excuses for the warranty being void etc.
It is even worse for those that have a fault in their foldable screens. Good luck in getting anything from the Samsung warranty.
In fact I also bought 2 of their recently released Book 2 Pro 360 laptops and am having immense issues with their customer service. When a Samsung product develops a fault or you have an issue with it, do not expect any support from Samsung customer services.
Not sure how Apple customer services are these days as I haven't bought a product from them in about 10 years. However, when I was exclusively Apple, I do recall their customer services being up there with Amazon and John Lewis.
Folding Samsung phones right now are not a good idea if there is poor customer service behind it.
I have the exact polar experience to you when my Fold 2 front screen lost it's touch, with a quick midnight call to Samsung 24 hr service a guy popped around picked up my F2 gave me a loan note, sent me 2 update sms and returned the repaired F2 in 2 days. I do not know any other OEM who offers this level of service included
I also have a Samsung 15" Pro 360 and my son bought the just the 13" book at the same time and my wife has the 12" arm book, no issues what so ever
I also received excellent support from Razer when my 15" lost is multi colour KB options who arranged free pick-up courier service to Singapore and back in a week
Similarly Dell onsite support was great in the UK with my sons laptop I bought and eventually after 3 attempts to fix they gave us a full cash refund and a £300 voucher
MS the same on a recall for a screen fault on SB2 just sent a pre paid box and laptop was back in a week
Apple on the other hand wanted a $60 processing fee just to open the MBA 12" and a ridiculous replacement cost for a logic board, let alone the 5 charging bricks I have had to replace, flaking screens, etc
Its always easy to find negative feedback on the internet and these forums are littered with class actions against Apple, but far less on other OEMs. That seems reasonably indicative of the brick wall you hit with Apple warranty issues
