How to: Fix the Color Balance (Yellow Tint) on the Galaxy S6

The Galaxy S6 includes 4 screen modes: Adaptive display, AMOLED cinema, AMOLED photo, and Basic.  Basic mode is the most color accurate with saturation significantly reduced but usually appears to have a yellow tint.  Our review of the Galaxy S6 noticed varying degrees of yellow tint in basic mode across several devices.  The Galaxy S7's color calibration is a lot better with most devices having a neutral white in basic mode.

Samsung App Changes

If you've been avoiding the updates to Samsung apps then you'll notice the push of updates to you

• Dramatically improved RAM management - able to run 8+ apps without them reloading.  Your experience may vary based on the app/game opened

• Weather app now shows the hourly temperature in 4 hour blocks at the top and defaults to a minimized daily weather without the temperature when the current temperature is maximized.  You can swipe up to minimize the current temperature and show the Daily temperature
  

Should you upgrade

The Galaxy S6 Marshmallow update brings noticeable improvements to speed and idle battery life.  If you haven't already loaded up a different theme or switched the launcher, it gives the S6 a fresh coat of paint with flat icons and new notification pane (You can also do it with the [Kendi] TouchWiz 6.0 theme.  Overall it's a very stable firmware that doesn't change the S6 much from it's latest Lollipop firmware.  I upgraded and don't regret doing it.

Samsung Galaxy G6 Long Term Review

After disappointing sales of the Galaxy S5, Samsung had to make a big turnaround with its next Galaxy phone. Introducing the fruit of its project zero, the new Galaxy S6.

An aluminum framed phone powered with Samsung's own Exynos 7420 processor sandwiched between two slabs of Gorilla glass 4, the Galaxy S6 lives up to its flagship status with 3GB of RAM, Quad HD Super AMOLED display, 16MP F1.9 aperture rear camera, 5MP front camera, IR blaster, Quick Charge 2.0, Bluetooth 3.0, 802.11ac WiFi support, wireless charging, fingerprint scanner, biometric reader, and GPS/GLONASS support to name a few. The downside is the lack of microSD support, switch to the smaller nano SIM, and smallish battery (2559mAH) that's non-removable.
