Samsung e5 is one of the best phone which work a great way til you update it .yes I repeat till you update it after update things go worse yes is starts with the problem of hanging and goes on with the phone not working properly. The apps stop working suddenly the screen goes blackout.so in order to use your phone in a proper manner please do not update it from kit kat version to 5.1 marshmallow.except from that the phone is all around a good product from Samsung having good quality camera and average processor.
