Specifications of the Celkon Ultra Q500 will more or less leave you impressed. A 1.2GHz quad-core processor powers the device, the CPU cores being based on ARM s low-power Cortex A7 microarchitecture. That is, as previously stated, accompanied by 2GB of RAM. The Celkon Ultra Q500 has got a 5-inch HD display, which translates to a crisp 294 PPI pixel density. It s not the best PPI figure in the world, but it certainly beats almost every other smartphone in its price bracket.
