The S1 is powered by a Qualcomm Snapdragon S4 Play SoC comprising four ARM Cortex-A5 CPU cores running at 1.2GHz each and Adreno 203 for graphics. Compared to the MediaTek MT6589 chipset in the Canvas HD, the S4 Play isn't very efficient. For starters, it still uses the older 45nm fabrication process instead of the 28nm process, and the CPU cores are based on the older Cortex-A5 architecture instead of the Cortex-A7 cores used in the MT6589 chipset. Even the GPU is older and only supports up to 720p video. You won't notice much of a difference in simple apps and the UI in general, but the difference is apparent in stressful apps like games. Coming to the 4.5-inch display, Karbonn says it's an IPS panel, but we have a hard time believing them. The viewing angles and colours are very poor for an IPS panel and the screen sensitivity is not very good either. Colours feel oversaturated and the screen is not lit evenly, making the corners seem darker than the rest of the screen. There's also very jarring colour shift, which happens when you tilt the screen even slightly in most directions. The OS is stock Jelly Bean 4.1.2 with just minor tweaks here and there. You get toggle switches in the notification bar and a couple of extra settings for managing the two SIM cards. There's no option for OTA updates nor an app to manage updates, so we doubt there will be any in the future.Media is handled by the stock video and audio player. Audio quality is strictly average, but audio through the loudspeaker is pretty good. You also get an audio manager that lets you adjust the audio from the loudspeaker and headphones individually. You can adjust the bass and even apply equalizer settings for the overall audio. We couldn't find a radio app, however. There's a video streaming app called nexGTv pre-installed as well. The video player only supports MP4 files ad that too only up to 720p. Full HD 1080p videos do play but not without stutter. There's 4GB of on board memory, which can be expanded via the hot-swappable micro SD card slot. This dual-SIM phone supports tri-band GSM and single band 3G. Only one SIM is capable of 3G data while the other one is only 2G. Other connectivity options include Wi-Fi 'n', Bluetooth, GPS and USB for charging and data storage. Chrome is pre-installed as well, so web browsing is a pleasant experience. One big problem we did encounter was call quality, which wasn't very good. The earpiece is loud, but the sound distorts even at medium volume and is not very pleasant. Also, the person on the other end is unable to hear clearly when you speak a little softly, which is not an issue on most handsets. The 5MP camera has an easy to use interface with plenty of options to tweak. There are options for adjusting the white balance, face detection, colour effect, anti-banding and red-eye reduction. The interface also has the option to use the front camera along with the rear camera, a feature that's been touted a lot on the Galaxy S4. You can also shoot in a bunch of modes like Panorama, HDR, Smile, Speedily or Normal. Video recording maxes out at 720p and the dual-camera mode works for video as well.

Product with 1.2 Ghz quad core processor & 1GB RAM and many more features at such a low price it is value for money.

I think this is a reasonable cool phone
