Now lets talk about main disadvantages
Main disadvantages
Rear-mounted mono speakermicroUSB 2.0 is a downgrade over microUSB 3.0 on the Note 3The uneven gap between the metal frame and curved screen glass takes a few points away from an otherwise excellent buildNo enhanced resistance to liquids or dustWireless charging support only with an optional back cover
The main reason I dont like this phone is because it is too expensive, at this price bracket u will get s7, note 4 should be under 20000rs then it is worth ur money.
