The product is exelent you must go for it I am writing a review for this phone . this are very amazing product compair at its prize.
both front and back camera are very good.
the battery backup is awesome .
it has some other nice feaqture like samsung always does it.
it gives u a high optimized phone.
no signal problem.
it a must phone for office works who have lots of work in phone like sending mails etc. . and need a whole day battery backup for a heavy usage.
it is a premium mobile hand set with dual sim and micro-sd capability up to 256GB. the feel is good.
the only drawback is the tizen OS which is a propitiatory OS of samsung. its not open source like android.
but it is very nice mobile phone. I like this phone.
