It's been a year since Samsung launched its Galaxy S10 flagship line. But just because the Galaxy S20phones are available does not mean the company's 2019 line faded. The same goes for 2018's Galaxy S9 phones, which are serene being sold by retailers at deep discounts. 

As a shimmering rundown on just the main S10 models, the marquee phones are the Galaxy S10 and S10 Plus. The S10 features a 6.1-inch point to, three rear cameras and a single front-facing camera. The S10 Plus, from the time when, is a bit larger with a 6.4-inch screen. The bigger point to is accommodated with a higher-capacity battery (a 4,100-mAh battery compared to the Galaxy S10's 3,400-mAh one). It, too, has three rear cameras, but Samsung added a second 8-megapixel front-facing camera.

The Galaxy S10E is not as expensive as the others. With its 5.8-inch screen it's slightly smaller than the rest and has a smaller-capacity 3,100-mAh battery. It only has dual rear cameras and, like the Galaxy S10, a single front-facing shooter. Lastly, there's the Galaxy S10 5G. It has a 6.7-inch mask and works on high-speed 5G mobile networks. It launched first exclusively on Verizon, but other carriers sell it too. On the back is a whopping four-camera setup, which includes a 3D Depth camera.

Meanwhile, 2018's Galaxy S9 has a 5.8-inch mask, a single 12-megapixel rear camera, a Snapdragon 845 processor and less expandable memory (up to 400GB compared to the Galaxy S10s' 512GB). The Galaxy S9 has a smaller, third memory option, too. It has a 64GB tier, while the Galaxy S10 and S10 Plus launch at 128GB and 512GB, respectively.
