It is worth to buy note 4 as it gives endless software customisation, the curve design make easier to hold and feels great in hand and the metal body gives a premium feel and also have hybrid slot.
Speaker quality not something great but display good at a price.
Decent camera but not as best as honor 6, it has awesome battery life lasting for a day even with heavy usage however you charging is terrible as it takes 2 hours to charge.
In all worth to buy for a price I personally using it for one month however worst part is you have to struggle to buy due to super flash sales and difficult to get
