Current daily driver is a Samsung Galaxy Z Fold 4. Pretty happy with its compact size when folded, and it serves as a mini-tablet of sorts when unfolded. It's also the first phone I've owned that I've not needed to worry about running out of juice midway throughout the day. Though I find its quite hard to find a suitable table stand for it, especially if using it unfolded.
My Android journey began in January 2014 with a Sony Xperia Z1, upgraded from an iPhone 4S with a busted home button. It was a pretty great introduction to the Android world with Sony's near-stock interface (when compared with the dark days of T**chwiz bloatware and whatnot) and lasted until January 2016 when I upgraded to a Sony Xperia Z5 Premium. The lack of an SD card slot of the Samsung Galaxy Note 5 made me hold my nose and get the Z5P despite its Snapdragon 810 SoC, and I endured its abysmal 3.5 hour SOT until 20 months later I upgraded to a red Sony Xperia XZ Premium. This was a really good looking phone and its SD835 SoC was definitely a far cry from the 810 with 5.5 to 6 hours SOT. 28 months of use later and the XZP unfortunately started lagging, which prompted me to try out Samsung. The Note 10+ impressed me with its nearly bezelless screen and s-pen, but the Exynos 9825 SoC was pretty meh at battery life. So another 28 months later and I've upgraded to the SD 8+ Gen 1 Fold 4.
