I bought a refurbished iphone X in March from Apple...yesterday display had a vertical green line down left side before it stopped working. After 4 phone calls and over 2 hours with Apple support they are sending me a new (refurbed) iphone and I will send my old phone back. I don't understand why this was so hard....a simple google search shows this is a known issue and they put a hold on the credit card for the price of the phone they're sending me until I return the broken device. My impression is Apple products no longer "just work" and dealing with customer support was exceedingly painfull. Maybe it's time to give up my iMac, iPad, airpods, apple watch and macbooks I've purchased over the years and buy cheap Andriod phones and windows computers....
