That's not entirely true. The problems I encountered on the Note 4 were no different from those encountered by my flatmate who was using the Nexus 6. For example if we did a clean install. What's App or LINE would both open the camera in ~1-2 seconds. With only installing a few apps (facebook, twitter, whats app, line...) after 1 month, both the note 4 and nexus would degrade in performance that What's App or LINE would take ~8 seconds to open the camera... After using an iPhone 6s+ for over a year, the camera opens instantly, every time... I thought it was my Note 4 and got it replaced twice... my flatmate couldn't replace the nexus since he bought it in Hong Kong and Google Singapore wont help. Everyone I know who has Android says iPhone sucks, but constantly complain their (android) phones are slow and laggy. Again, I don't understand why people like Android.
