I’ve used a Z Fold 4 for two years now and it’s been the best phone I’ve ever had. Desktop versions of websites, on my phone, without feeling cramped. Two apps side by side, both roughly the size of a usual phone screen. Huge screen for retro emulation using a Bluetooth controller. All with still having a small screen for one handed use and more traditional scrolling.
Games like Hearthstone, Gwent, Chess, Baldur’s Gate Enhanced Edition, Roller Coaster Tycoon Classic, feel way more playable.
At this point, using any other device feels limited and cramped in ways that a big screen doesn’t.
My only complaint has been price, and I only got mine because my company paid for it
