The Zen Ultrafone 503 3G poses a 4-inch TFT capacitive touchscreen with a resolution of 480 x 800 pixels. It runs Android v4.2.2 Jelly Bean OS out of the box. The smartphone has an impressive dual-core processor clocked at 1.2GHz but what is bound to limit the number of apps you can run simultaneously is the paltry 256MB of RAM.
Camera and Storage
It has a 3.2MP camera with features like LED flash, digital zoom and touch focus at the rear end. A 1.3MP camera supporting video calling is available on the front as well. The smartphone has an internal memory of just 512MB which is expandable up to 32GB.
Battery and Connectivity
The Zen Ultrafone 503 3G sports all the regular connectivity options in the form of Bluetooth, GPS, Wi-Fi 802.11, 3G and GPRS with EDGE. It is fuelled by a miserable 1,500mAh Li-ion battery which delivers up to 4 hours of talk time and up to 72 hours of standby time in 2G network.
In case you are searching for a cheap but stylish smartphone to flaunt, the Zen Ultrafone 503 3G is a good choice. However, barring the good looks and the ability to support 3G, this phone does not have much on offer. Recommended for beginners.
