It seems that there are two Galaxy Alpha siblings in the works the Galaxy A5 and now the Galaxy A3 (aka SM-A300). This one packs a 64-bit processor but curiously is close to low-end in most of its specs.
A GFX Bench info page reveals a 4.8" screen with qHD resolution (540 x 960 pixels) and two cameras 8MP on the back, 5MP on the front, both capable of 1080p video. The handset runs Android 4.4.4 KitKat and has 5GB of user-available storage, presumably 8GB total.
The Galaxy A3 is powered by a Snapdragon 410 chipset with four Cortex-A53 CPU cores that ran at 1.2GHz for the benchmark but the User Agent Profile on Samsung's website points to a clock speed of 1.4GHz. The chipset is paired with an Adreno 306 GPU and 1GB of RAM.
We havent seen images of the device just yet to tell if this Alpha sub-series of Galaxy phones will share in the most important trait thin, metal bodies. Info from TENAA puts the Galaxy A5 at 6.7mm thick and 126g and its specs are hardly flagship material either.
I use this phone and its the best of Samsung. every one around me is saving up to get it.
I tried Chinese brand, and yes they are good for a month or two. After that most of its surface deteriorates, screens, sides, back got no scratches but it's no longer polished. It's like holding a 2 yearold phone.
