An unknown Samsung device was leaked yesterday on the internet. It was benchmarked sporting an Exynos 8890 chipset and was codenamed "Lucky". Seven is considered a lucky number in most cultures, so it is reasonable to think that Project Lucky is codename for Samsung Galaxy S7 being developed.
The prototype that went through the AnTuTu benchmark today came with a 5.7-inch QHD touchscreen, a 16 MP rear camera, a 5 MP front snapper, 4GB of RAM, and 64GB of internal storage. It ran Android 5.1.1 Lollipop at the time.
Samsung wants to keep the ultrafast UFS 2.0 storage and is trying to make it compatibile with microSD cards.
