The Samsung Galaxy S20 FE gets you a 120Hz display, 5G, and top performance at an affordable price. If you don't need the latest flagship, this is really close and it's now on sale at $549 (from the regular $700).
With a sturdier hinge and a larger 120Hz display, the Galaxy Z Fold 2 improves upon the original's many flaws delivering a better experience, but at $2,000, it targets a very small niche.
With a 108-megapixel sensor, 100x zoom, 8K video recording and 40-MP selfie camera, the real appeal of the S20 Ultra is for mobile photography. But the price tag is so high that the phone is clearly not for everyone.
