Apple did what was once the unthinkable while predictable Samsung delivers again. Right or wrong, this is a fight of old versus new, the Galaxy Note is in its fourth generation while the iPhone 6 Plus is Apple's first phablet ever.
Samsung's release cadence dictates that the Galaxy Note is the H2 flagship, keen to assert its superiority over an already feature-rich Galaxy S. iPhones come once a year, even the first-time iPhone 6 Plus phablet. The situation is similar though, the Plus is better equipped than the vanilla iPhone 6.
Samsung is known for its feature-rich (some would say "overflowing"), utilitarian designs but it's slowly coming around to metal designs with the Alpha and now the Galaxy Note 4. It's just a metal rim, so the user-replaceable battery and microSD card slot are intact.
The screen size also remained unchanged (5.7") to keep the device manageable single-handedly, but resolution increased to QHD. The defining feature of the Note series, the S Pen, was also improved and Samsung included optical image stabilization (OIS) to the list of camera specs.
The biggest change for Apple is the screen - after years of keeping just about the same size and sharpness, the company took the plunge. The design language changed more than it did for the Galaxy and is now smooth and rounded like an iPod Touch, it's impressively slim too. It's the OIS-enabled camera that is the other advantage over the vanilla iPhone 6.
With bigger screens, both phones and their respective platforms (iOS and Android + TouchWiz) have their ways of boosting usability.
You're are not alone. Typing this on a note 4. Changed the battery for the second time last week. Not my primary device though. Use sparingly these days
as of today, in august 2020, i'm still using my half decade old Note4 as a daily driver, changed battery once and still its working as fine as day one.
Bro it should be a screen problem ,if its makes a Samsung tune once switched and doesn't display find a new screen but its some how expensive since its a complete screen
