Unihertz Jelly 2 Smartphone
As phone screen sizes continue to expand, Unihertz is going the other direction with its Jelly 2. Billed as "the world's smallest Android 10 4G smartphone", it's roughly the size of a credit card, with a pint-sized 3-inch, 326-ppi screen, an 8-megapixel front camera, and 16-megapixel rear camera. Despite its small size, it still supports dual SIM cards, microSD expansion of the 6GB of internal storage, USB-C charging for the 2,000 mAh battery, and nearly every possible band of LTE. Ideal for use as a secondary device for travel or less-distracting nights out.
