The LG G4 is a step back compared to its predecessors, and not a flagship that you should buy. If the camera is your first priority then this is the best you can get, but apart from that, theres no real reason to buy this phone.
PROS:
-Brilliant Display
-Best in class Camera
CONS:
-Kind of average performance
-Poor build quality
MY FINAL VERDICT!
If you own a LG G3, then hold on to it, because the G4 is not a worthy upgrade to it. If on the other hand you want a flagship device this year, then don’t the Samsung Galaxy S6 still remains your best bet. The LG G4 has a killer camera though, so if the camera is your first priority, go for it. For everything else, look to Samsung.
