[Galaxy Note 4 Q&A, Help & Troubleshooting] arjun90:
Every Galaxy devices I've come across, whether in the stores or personally speaking, have a misaligned home button, looks more prominent on one side compared to the other. Unfortunately, shows Samsung's innovation. I've been through over a dozen Note 4's, the AT&T variants had an extremely loose feel, whereas the T-Mobile variant is just about right.

Judging by the pictures, looks normal to me, based on Samsung's manufacturing standards if you ask me.

Shouldn't require too much force. The click shouldn't be too loud and tacky, the sound be soft.

When going through the return and exchange process for the Note 4's, each home button had its distinctive feel, some felt squishy on the left side with a significant gap between the right side and display. One home button even had a noticeable scratch on the aluminium part of the button.

Regarding the Oleophobic coating, its advised to never clean the display with water or oily hands. Install a screen protector from day one. 70% isopropyl alcohol is the way to go.

If you press hard enough you can actually re-position and resettle the button more to the right to fill that gap you were referring to. I've felt buttons in the which which felt like something protruding through the middle as I move my index finger from left to right (edge-to-edge) on the home button.

It will look slightly crooked to you because Samsung never added adequate cushioning to keep the button centered. Overtime, the button will settle itself. Some Note 4's, even as seen in previous Galaxy phone, have light from the capacitative phones leaking between the gap of the home button and capacitative buttons; best seen in dark-room settings.

Over time, the home button wears off a bit. Every Galaxy device I've owned, I've always added a piece of scotch tape on the home button to not mess up with the alignment, etc. Everytime it came to reselling the device, the home button would feel as new to the subsequent owner as it did to me.

Its definitely the way its supposed to be. Some home buttons will even appear flushed / recessed whereas some will even looked elevated sticking out from the display. Samsung doesn't take this into account in their QC process, because they add the minimum adhesive to make the plastic home button work. If they had changed their materials and design a bit, would have made a dramatic difference; but they didn't since the Galaxy S2 days.

To say the issue doesn't exist, doesn't mean you're wrong, its just how far your eyes can see. The majority paid over $700 for a device which is suppose to compete with the inferior iPhone. Samsung had to make some compromise somewhere. Samsung believes and priorities in profits and margins, manufactures virtually everything in the IT Sector, and doesn't have the caliber to keep a quality control basis or invest in the amount of innovation compared to Apple; however the INTERNAL technology in Samsung's phones will always be superior, because they innovate and design them, from SoC's to Display technology ; Apples priorities their development based on innovation, patents, and EXTERNAL design more over their profits and margins, their most recent report is mere coincidence.
