I think Asus zenfone laser 2 550 KL is completely a hanging phone it hangs all the time means if I take a photo and from the side screen I want to open it and to view on the photo if I click on that it will take time of 1 minute to open it means I am just frustrated from this phone its just very hanging phone its a headache I have never seen such phone I have used Samsung Galaxy j7 Samsung Galaxy J5 . Note 2 and they are just fine. Note 2 was a bit slow but not this much as I am facing with this Asus zenfone 2 kindly fix or give some update so that can be fluent and easy to use
