I have a Samsung S21 ultra, and the other week it auto updated the phone to android 12. This update caused a malfunction on my motherboard leaving me unable to use my sim card (it has auto blocked itself). So now I have to go to a service center and they tell me they can't fix the issue because of a small crack on my screen. Samsung refuses to fix a problem that their update caused because of a crack on my screen. So they force me to cough up $500 to replace the screen before they even consider fixing the motherboard. Samsung refuses to take accountability for this and won't fix a problem that THEIR update has caused. Over the phone the lady was nice enough but completely unhelpful and all I got out of it was a %15 voucher for a new phone (as if I'd buy another phone from them?!) So thanks for making me pay $500 for your f**k-up
