Samsung Galaxy J7 Prime
Samsung's Galaxy J7 series is always one of the best phones for those on a budget. Each year for the past few years, it's arrived for around $200 with impressive specs and all the essentials. It's not the best phone, but it delivers everyone you need, realistically.
Whether that's the J7 Prime, J7V, J7 Refine, or any of the other weird names carriers give it, the Galaxy J7 Prime is worth recommending.
You get a 5.5-inch Full HD screen, 13-Megapixel camera, Android Oreo, 32GB of storage with 3GB of RAM, and it takes a microSD slot. It's a good little phone that's sold almost everywhere.
