The phone Samsung S4 is so disappointing because the name of Samsung is so big and such a big company is launching such a phone .
Battery backup is worst compared to the other mobile brands.Heats up quickly and performance is also not up to the mark along with that like other Samsung phones it also hangs.Camera quality is also not so good as we compare this phone from other phones.And last but not least the price we are going to pay for this phone is quite more compared to other top brands.
