they are both amoled screens, right?
usually it shoult last longer than one year, but amoled has a really short lifetime, compaired to all anorganic screens (e. g. LCD)
expecially the blue subpixels (physicaly more energetic than read light) gets weard out a lot faster
and organic screens get weard faster if they get hot or warmer than they should (cooling the screen extends lifetime (in a bag <-> close to the body)
but this are just some background informations, i cant really imagine that a amoled screen is used up in around a year
