The Samsung Galaxy note 4 is one of the most loved smartphone by Samsung over the time of 2014 and early 2015 till the point the S6 came out! Overall, the Samsung Galaxy Note 4 was one of the best devices in that time for the company and had to offer a lot of things too!
The Samsung Galaxy S4 was one of the first devices by the company to feature technologies like Heart rate and finger print sensors!
Though, I like the fact that the device had a fingerprint scanner, I really hate that whenever I had to unlock the device, I had to swipe through the finger print scanner! At that time also, when the Samsung Galaxy Note 4 was launched, we had several other phones with the fingerprint scanner but without any swiping gesture needed! So, yes, I do feel that Samsubg had to stand off doing it, and pretty much failed with the idea!
Overall, I also hated the UI part of the device in the starting when the device didn’t recieve that much updates! The UI turned out to be really very heavy for the device and kept on hanging and lagging while sirfing through the ROM!
