It's hard to take this seriously. I used many of the older Samsungs in the Galaxy S series and I always rooted them because the carrier bloatware made them so slow, and yes they got slower as time went along. There's no way any early Galaxy S is faster than my Pixel 8 Pro doing equivalent tasks, evaluated objectively.The old models were never slowed down like the new ones. The old s4 is faster than what I am using now. Plus I can't even change my battery now. Did you hear how android is going to pre approve all apps now? There goes fdroid and the other sites. Bummer.
The other thing is that software support ended long ago for these early Galaxy S models. There's no way I'd even turn one on nowadays unless it either was never connected to the Internet, or had some hacker rom like Lineage that was fairly recently updated.
