I only knew of one person and hers was a goner in half a year, but she somehow managed to switch phones under warranty (didn't know you can do that) instead of repairing. That being said, I have OnePlus Open (foldable phone), but it's not the main screen that's constantly gets bent which is the sus part to me. I open it at best 3-4 times a day when I need the large screen, not every time I need to use it. Mine is 2.5 years old, going strong. Some months ago I was in a phone shop waiting in line to buy a HDMI adapter for it and there was this lady arguing with the clerk about why can't she submit her flip for warranty if it's not her fault. 3 years actually blows my mind
