I remember that Samsung had trash lifespan and lasted about a year or two. It was so bad that people were installing custom Roms to extend its lifespan. You can't even install custom Roms on newer devices. Also foldable phones are experimental and are way too expensive.

Also you can't unlock the bootloader anymore for Samsung devices. So no custom Roms to extend the lifespan anymore.
when Google originally came out with Nexus phones it was like $300 but they always sold out within an hour of going on sale
now that it's the same price as Samsung which is whack
and i am definitely not going to use Apple
