> My Samsung Galaxy Note 2 and S2 are still working. My Galaxy S4 and Note 4 were working quite fine ~18 months later, but only technically. They were aggravatingly slow and I was factory-resetting them each every 3 months, also rooted them and de-bloated them quite thoroughly. This rejuvenated them for a while but then some mere 1-2 months later they were back to a crawl. We can throw anecdotal evidence around until the end of time but to say older Samsung are working only applies in very strict dictionary terms and not what an average user would find acceptable (f.ex. various functions were routinely taking 2-3 seconds before the device responded). Several acquaintances had the same experiences.
