[Samsung Gear S2] optimummind:
As many of you guys knows, the Gear S2 - Sport, Classic, and 3G - have a software bug whereby the Always On setting doesn't work/stick.

Even when one sets the Always On to "On," the watchface will turn off (go blank) after a while instead of always showing the Ambient Watchface. The only way to keep the watch display always on is by also keeping on the Wakeup Gesture setting. Doing so, unfortunately, leads to a massive battery drain.

I've contacted Samsung twice about this issue and each time they reply saying I'm the ONLY person to report this issue and for me to perform a Factory Reset. I did do a factory reset with and without restoring my backup data and the Always On bug is still there.

So let us collectively work together and each of us submit a bug report to Samsung. Here is the link to their online submission form.

The more people submit, the better our chances of getting a fix, sooner rather than later.

Edit, 12-30-15, with workaround to always-on issue:

Here is my tested workaround that is working for me right now on my AT&T Gear S2 3G (R730A) on the OL3 firmware.

I have tested this for 2 days and my watch display is always on and showing the dimmed, ambient watchface and NOT blacking out. For today, my Gear S2 3G was taken off the charger at 6:50AM and it's currently at 62% battery level at 5:36PM. And now at 12:24am, I'm at 35% battery left.

My Gear S2 settings:

-Display: Watch Always On = On

-Display: Brightness = 5

-Device: Wake-up Gesture = Off

-Connections: Bluetooth = On

-Connections: Mobile networks = Always off (I'm on Sprint)

-Connections: WiFi = Off

-Connections: NFC = Off

-Connections: Location = On, GPS
​

I have not tested out this method on that many watchfaces but the ones I'll be mentioning shortly always stay turned on in the Ambient Mode without blacking out.

** Apps from the Gear store I'm using:

1. Tested watchfaces:

-[Clay] Futuristic

-Gear O'Clock: Digital Sense

-Gear O'Clock December

-Calendar Digital Watch.

2. HR Monitor by appyhapps.nl

** Steps I have taken **

1. Go into your Settings and set "Watch always on" to On and "Wakeup Gestures" to Off.

2. Open the HR Monitor app and click on the Settings icon (the Gear icon). And set it up like this:

-Exercise mode = off

-Internal = 15 minutes

-Show date = Off

-Turn screen on with each heart rate reading = On

-Keep screen on during run in exercise mode = Off

-Dim screen brightness in exercise mode = Off

-All the options under Alarm = Off

3. Press the U-turn arrow icon to go back to the Main Screen of the app.

4. Press the Start arrow icon to begin the heart rate monitoring app.

5. Go back to the watchface screen homepage by pressing the Home button on the Gear S2. Long-press on your current watchface and select the watchface of your choice.

6. Finished!

By using this method, my Gear S2 correctly shows the ambient watchface and DOES NOT turn off the screen after a while.

The impact to my battery life is minimal and I can easily last all day until when I charge my watch at night, which is around 11:30PM.

What is interesting is that even though it was set within HR Monitor to turn on the screen when a reading is taken, most of the time the screen is not turned on to show the HR Monitor monitoring screen. Instead, the ambient watchface is maintained and the heart rate is measured in the background. This is probably why there is minimal, if any, impact to my battery life.

I don't know why this method works but no complaints here. Now my Gear S2 is behaving as it did when I first purchased it on November 20th on launch day (on AT&T) and when I was on the original firmware. My Gear S2 has gone through 2 firmware updates since then and one of those newer firmware updates changed the behavior of the always-on mode. FU Samsung!! :o
