I have been using this phone from past three and a half month. and its an ok phone from samsung in this range.It has neither a notification sensor nor a fingerprint scanner.Its definitely not a value for money phone.Here are the pros and cons:
pros:
1.slim metallic body.
cameras quality is good, front 5, back 13mp.
no hanging at all.
4G support.
supports OTG.
cons:
optional sim/ sd card slot.
Batter backup of the phone is not good.
no fingerprint scanner.
no notification sensor.
Do not go for this phone as there are better phone in the same price range.
