It is slim( 8.6mm) phone. Audio quality is medium, 1GB RAM satisfy its need, some problem in samsung keyboard should be fixed, camera quality is brilliant, looks is awesome, sometimes lags due to overuse of apps, touch response is good, 540×960 pixel display is ok, it supports 1080hd video recording which is quite stronger part of this phone, fastwr download speed of 21mbps, but take long time to charge the phone.
