Blue light causes glare.  But what if you have your S8 in AMOLED Photo mode, or have manually customized the color temperature in Adaptive Display mode?  That’s an important step in getting more accurate colors, but that’s not what the Blue Light filter is about.  You see, even if your screen is accurately displaying whites and white, and not blueish, it is still send blue light waves into your eyes which inhibit the production and absorption of melatonin, a natural chemical required to make you feel sleepy, and then eventually make you ready to wake up feeling refreshed.  In other words, you are reprogramming your body’s circadian rhythms.

 

The Blue Light filter actually creates an amber colored light on your phone when the sun goes down.  At first, it is subtle and mostly imperceptible, but the amber light gets stronger as the evening goes on.  Blue light filters are not required during the day.

Now you’ll be able to read at night and still feel sleepy.  Scientific studies have shown a link between light at night and diabetes, heart disease, obesity, macular degeneration, glaucoma, cataracts, and both prostate and breast cancer.  You can read more about the science behind it at the following links:

Here is a excerpt from the Harvard study:

  • Use dim red lights for night lights. Red light has the least power to shift circadian rhythm and suppress melatonin.
  • Avoid looking at bright screens beginning two to three hours before bed.
  • If you work a night shift or use a lot of electronic devices at night, consider wearing blue-blocking glasses or installing an app that filters the blue/green wavelength at night.
  • Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.

Screenshot_20170619-135653.pngYou can access the Blue Light Filter menu from the "Display Settings" in your phone's "Settings" app.  In order for the automatic “Sunrise to Sunset” mode in to work in Samsung’s blue light filter, you’ll need location, a.k.a., GPS on all of the time.  I find that uses more battery power than I would like, so I just set a custom schedule of 7:00 p.m. to 7:00 a.m.  Yeah, this doesn’t take in to account the changing sunrises and sunsets through-out the year, but it gets the job done with no discernible impact on battery life. You can also toggle it on or off from the top menu drawer on your phone.

 

 

I’ve used an excellent app called “Twilight Pro”, that accomplishes a similar goal as Samsung’s blue light filter, and can turn on accurately at sunset and turn off at sunrise without using GPS, but it is technically using a screen overlay, which can introduce some slight problems.  Some apps see screen overlays as security threats, as several pieces of malware can use an overly to spy on every screen touch you make and every character you type, including account numbers and passwords.  Of course, Twilight Pro isn’t malware, and doesn’t spy on you, but all of this is moot when using Blue Light Filter, which runs natively, and will not show up as a false positive screen overlay.  Bottom line is, I don’t need Twilight Pro on my S8.

Galaxy Apps.PNGSamsung has a special version of the Amazon Kindle e-reader app called “Kindle for Samsung”.  You can only install it from Samsung’s app store, which they call, “Galaxy Apps”.  It’s pre-installed on your Galaxy S8, or any other recent Samsung device, including their excellent line of tablets.

 You can install this app even if you already have the regular Kindle app installed from Google Play store or the Amazon App store.Screenshot_20170619-105218.png

 

Each month, there are four books to choose from, representing a variety of genres.  You will be able to choose one free book.  The available books show up on the first of each month and are available for the entire month.

 

Screenshot_20170619-105250.pngTo find the offer for the month, open the Kindle for Samsung app.  Now, from within the app, touch the menu button in the top-left corner of your screen; it is designated by three horizontal lines. Next, choose the option titled, “Samsung Book Deals”; it’s fifth down from the top.  You will likely initially see only three books, but you can slide those over to see the fourth offering.  Clicking on the book’s cover will give you a detailed description of that book and the ability to redeem that month’s offer.  Once you purchase your month’s quota of free books, (one book per month), you will lose the ability to purchase the other three for free, however, they are often still offered at a heavily discounted rate.  Many of the books I’ve seen can be purchased for less than two dollars, while the full retail price might be twelve to fifteen dollars.

Once you purchase the book, (for free), it will show up permanently in your Kindle library and will be available on all of your devices that have access to Kindle.  Your reading progress will be saved and synced across devices.  As an example, you can begin reading your free e-book on your Galaxy S8 as soon as you acquire it, then pick up where you left off on your Kindle.  You do not need to use the Kindle for Samsung app to read it at all, merely for the original purchase.

 

You may find it helpful to set a monthly reminder to come back at the beginning of each month to see the new selections.  Samsung has a useful app for that appropriately named, “Reminders”.Screenshot_20170619-111948.png
