Next to the alleged Galaxy J4 and Galaxy J6, as well as the US variant of the updated Galaxy J3, an Exynos 7870-powered Samsung handset was spotted on Geekbench. Codenamed SM-J800FN, this one is expected to launch as the Galaxy J8 and runs Android 8.0 Oreo. Older rumors mentioned it would feature 4 GB RAM, 64 GB internal storage, and a 5.5-inch 720p display, but nothing is official yet.
