[Galaxy Note 4 General] arjun90:
It will always depend where your eyes are trained. Many don't use the right Apps to diagnose their screens. Going through a dozen devices in a row, each and everyone of them had a flaw with gamma / color distribution.

In addition to a dozen Note 4's I've personally gone through, the in-store demo units were significantly flawed as well. Sometimes, I feel pity for the In-Store reps who don't have the eye trained to detect such anomalies. Their job is to make a sale and move on to the next victim. Its a disgrace to both the retail chain operators and obviously, Samsung. Thanks to Samsung's carelessness, their sales are soon to go down the drain, not that they are already lost significant sales in the last quarter. What goes around, comes around. Nobody is really getting a good screen, all of them are majorly flawed.

Most Note 4 / AMOLED screen owners use their devices with their display brightness set to High / or to a brightness where the hue doesn't significantly show, Adaptive Display On, and Never cross the less than 5% threshold for their brightness to automatically set to low as a result of low battery percentage remaining. These owners are never motivated to post on forums like XDA, because they simply don't realize the importance of this '5' year defect, yes this engineering flaw has persisted on AMOLED displays since 2010.

I agree with you. :good: However, many, including myself, expected better in every iteration of the AMOLED displays coming to the market on every new Flagship device that releases from Samsung. These anomalies can be corrected easily by software, not every gamut is calibrated equally because of different workers working at different hours and different assembly factories spread throughout the Asian Continent (China,Vietnam, and Korea).

The first four Note 4's I had gone through were Made in Korea and sold via AT&T, all four had the purple / pink hue clearly visible at high brightness; even with the screen being bright enough to excite me, the anomaly was beyond acceptable. The first two Note 4's purchased through T-Mobile online, one having the pink clearly visible throughout the display, and the second display being completely warm with a yellow tint throughout the display were beyond acceptable. The third, purchased at a store, was defective out of the box with horizontal lines that traversed through the entire 1/3 bottom of the display. The last, and final current one, was instant gratification at the store, where whites were the whitest I've ever seen on a Note 4, with the slightest hint of hue (tilt the screen), but not prevalent, and was acceptable, as the entire device was fully functional, with every feature working (no Camera focus flaw, accurate fingerprint sensor, heart rate monitor, solid home button and volume rocker and power button, bright flash). Don't ever set the brightness below the minimum factory-set point through any screen app downloaded from the Google Play Store. ;)

Read the reviews online carefully, AMOLED displays are known to carry a blue/purplish tint out of the box. Some will be pink. Pink, Blue, and Purple are within the same UV Spectrum, making the displays look "Cool." Whereas yellow makes the displays look "Warm." The Note 4's in general have Cool displays. Consider any device which sheds warm colors (Yellow-tint) beyond the manufacturing norm and tend to have lower lifespan, gets progressively worse overtime.
