Samsung has registered trademarks for its upcoming all metal Galaxy A smartphone series last month. It consisted of A6, A8 and A9. Out of the three, there's at least one that has surfaced up, unveiling its specifications - The A8. Though the device is still under development. We do have some of the details that will be featured in the device. The leak was claimed by SamMobile and according to their insiders, the A8 (SM-A800F) will be limited to China only. Which doesn't actually mean that the A8 wouldn't be available to rest of the world, the decision could change in the near future. While being a mid-range handset, the A8 flaunts an amazing array of specifications. It will feature a massive 5'7 inch Super-AMOLED Full HD display. Being only 5.9 mm thick and weighing around 140 grams, It would be Samsung's slimmest smartphone ever. It is 0.4 mm thinner than the current title holder of Samsung's slimmest devices, the A7 at 6.3 mm. Design-wise, it looks similar to the A7. The all metal phone will get a powerful 16 MP rear camera with a 5 MP front. It features an Octa-Core Snapdragon 615 processor (64 bit) with four ARM Cortex A53 CPU cores clocked at 1.7GHz and four ARM Cortex-A53 cores clocked at 1.0GHz along with a 2 GB of RAM, 16 GB internal storage and a 3050 mAH battery. There's no information currently about the storage expandability yet. It will run on Android 5.0.1 with Samsung's latest TouchWiz skin on top of it. It seems to be an impressive mid-range device and will be the largest of the Galaxy A series. Though there's nothing said about its official release date, it would be totally unfair if such a device doesn't make it to the markets outside China.
