A 5.5 inch phone with a super amoled curved display powered by 5100mah battery is sooo coool to use.just charge it 90min & enjoy with a 2 day backup.camera quality is good.I hv bought 32 gb 3gb variant for rs.12500 during offer period.its workin great.an external power saver switch has been added to this phone.but I think with 5100mah battery, there is not much use of this.home button can work as all 3 in 1 buttoni.e recent apps & back.fingerprint is so good to use.a good phone you should buy.
