I bought a Samsung Galaxy Note 3 in November 2013, and I am still using it in 2016 without any issues whatsoever.
Specifications wise it has a Full HD display of 5.7 with 386 ppi with gorilla glass 3 and a stylus which is why I bought this phone in first place.
Under the hood it has two quad core cpu running at 1.9 and 1.3 Ghz which is still great after 4 years it has 3 GB ram and 32 GB internal storage which is still high end spec’s in todays date but still Samsung is not upgrading to Marshmallow that I hate.
Camera is very good. Had to change its battery twice though but everything else works like new. I am happy with my Galaxy Note 3.
