I have purchased this phone before 3 years before, when andriod came to market. This phone has matel body so it is solid .it has 5 inch super almond screen with 1080×720 pixel density.
This phone runs on bada os version 2.0 which is samsung personal operating system. Means your security and privacy is fully secured by samsung. As in other phones it may not be. Battery backup is also good. U can talk for 5 huors and standby for 48 hours.
The main problem of this phone is it does not support any other social messangers accept facebook. You cant talk with this phone by using any app like in andriod. Whatsapp calling etc. If you r privacy concerned then you can buy this phone .
