The Galaxy A3's 4.5-inch 540p S-AMOLED display looks okay in the video. It's not the sharpest low-end display out there, but the 245ppi pixel density is decent, and you have to look hard for those pixels to really bug your eyes. The viewing angles look acceptable for this device category. However, the video compression doesn't really allow for precise judgements, so feel free to make your own observations.
As evident, the Galaxy A3 runs Android 4.4.4 KitKat topped of with Samsung's latest TouchWiz UI that you'll see in the Galaxy Note 4. Functionality such as My Magazine, Ultra power saving mode, and Private mode is present here, as is the revamped interface. The smartphone is ran by a quad-core 64-bit 1.2GHz Qualcomm processor, the Snapdragon 410, paired with 1GB of RAM. There's 16GB of expandable storage and a 1900mAh battery.
Although the Galaxy A3 is arguably the best "low-end" Android smartphone Samsung has produced, we believe the company will try to market it as a model from a "premium" series, which it probably won't be as affordable as it has to be to compete with the likes of Xiaomi and Meizu that have occupied the Chinese market. However, the A-series devices have a fair chance at competing with the iPhone 5S and iPhone 6 in Western markets. At the very least, this is a move in the right design and specs direction from Samsung.
