I've been using the Note 4 for a couple of years now and I continue to be impressed. It's plenty fast enough for the average home or business user. There's no lag in opening or switching between apps. The software is impressive - everything just works and I haven't observed any bugs or nuisances. Fingerprint sensor works a treat and is super convenient. I'm in Australia on the Optus network and have not had any issues with dropouts or connections. There was no 'Australia'option in the locales when I first booted it but I just chose Singapore and everything works fine. Apparently it lacks band 28 support however I have not noticed any problems using it in inner Melbourne. Perhaps it will be more of an issue when I travel to regional areas. The phone appears to be well constructed and feels light and sleek in the hand. It's good screen size too - I can comfortably read documents or watch movies for extended periods. It can be a little bulky to fit in some pockets but that's the tradeoff for having a note sized phone. The price is the best thing about this phone. I bought the 64gb version although I now realise that even the 16gb version would have been fine for my needs.
