I like them for nostalgia reasons, but definitely not for quality reasons. Though I must say, the rail service has refreshed them a few years back and they're not as bad as they used to be, though it does feel like they're the model that breaks down the most whenever there's some sort of extreme weather
The biggest problem is acceleration, though, which is still an issue for lines with many stops like the ones you see here. I imagine they'd do a lot better in countries that have lines where trains can go at least half an hour without stopping anywhere.
Maybe we'll see the return of double deckers once Tesla makes its first double decker car (I'm thinking "terrible electric RV with a tiny sleeping area on top") so they're cool again.
Samsung is under pressure, though, both from governments (EU Cyber Resilience Act will have consequences for unmaintained devices) and from the markets, bringing economic pressure from consumers who no longer accept their two years of updates when competitors offer a better deal.
I don't buy the "faster charging" scam, that's just burning through your battery so you'll need to buy a new phone sooner. I can wait 30 minutes per day to get my phone charged up, I don't need 200W to hit my phone battery. If anything, the fast charging is a tacit admission of phones needing to be charged often, covering up their terrible power consumption or small batteries.
