How can I prevent the S5's screen from coming on when charging completes?

[jtown]

I got my S5 today and it seems to have a "feature" that will be very damaging to the OLED display.  When it's done charging, the screen comes on and stays on.  I've been going through all the settings I can find and don't see anything that will prevent this.  Since static images burn into OLED screens, this is the last thing I want.  It's done the same thing several times.  My old phone (Galaxy Nexus) didn't do this.  When the Nexus finished charging, it did so with no fanfare.  The screen stayed off.

When the S5 is locked and the screen is off, there's no reason for the screen to come on for anything short of a phone call.  It certainly shouldn't come on and stay on just because the battery finished charging.  And, any time the display does come on without user input, it should turn off again automatically if it's idle for the length of the screen timeout.

I've got "Smart stay" turned off and "Screen timeout" set to 1 minute but, after it self-activates, it stays on indefinitely.  I've let it go for 20 minutes and the screen is still on.  How can I fix this?  If I can't get this behavior to stop, it's going back to the store.  I'm not paying $600 plus tax to have my lock screen burned onto my phone because I charge it at night.

Hello jtown,

I understand your concern with your display turning on and staying on after charging. Have you tried adjusting the Smart Stay settings? This feature is normally used so your display will not go to sleep while you are looking at the screen. To access this setting, please go to Settings, Display, Smart Stay and remove the check mark. Also, on that same screen, make sure Daydream is off as well. This setting allows a screensave to display while your phone is charging.

I should have mentioned that I've got "Smart stay" turned off and "Screen timeout" set to 1 minute but, after it self-activates, it stays on indefinitely.  Oh.  I did mention it.

I've also tried to use Daydream to display a pure black 1920x1080 image to simulate the screen being off but it never activated after the charging phase finished.  Again, the screen turns on and stays on.

Also, Daydream doesn't seem to do a darn thing during charging.  I let it sit for over 20 minutes while charging and it never kicked in.

On a related note, my Nexus 10 tablet, which is also running 4.4.2, does not exhibit this behavior.  When it's done charging, the screen stays off.  The only Android device that I have which turns the screen on at the completion of charging is the S5.

Hello jtown, your efforts are appreciated! Let's get to the bottom of this together. Can you please test the display setting via safe mode to see if there is a change: http://vz.to/RLkPjp We may have to run a hard reset to get the phone back to factory settings if issue persists. Keep us posted!

Thanks for the additional details jtown. We want you to enjoy as many aspects as possible on your new device; however, we understand everything may not be perfect for each person's preferences. Please be assured the latest screen technology protects against the potential of burn in. The function you are describing may be normal for this device. Did this start from the very beginning the first time you charged it? Does the same thing happen when you charge it with the device powered off?

i charge my s5 like all other phones i've had, when off....you might try it.

I don't turn my phone off.  When I had a landline, I didn't unplug it when I went to bed.  That's silly.

As for this screen being magic, it's not.  OLED screens burn in permanently.  Period.  Same as CRT and plasma screens.  LCD can get persistent images but that can usually be cleared up by playing video or something that runs all the pixels through a wide range of colors.

I'm sure this behavior is normal because it does it consistently.  But the fact that it's normal doesn't make it good or correct.  I'll try safe mode tonight and see if it makes a difference.  Does safe mode also disable all of the extra software, including the software pre-loaded by Verizon and Samsung or just the software I loaded?

[jtown]

Okay I've tried safe mode.  Let it run down to 98%, plugged it in, locked the screen, and waited.  A few minutes later, the screen came on showing the 100% icon at the top right, full battery icon just to the left of the time, 100% text to the left of that.

I'm not going to do a hard reset until I have confirmation that this is not normal behavior for the phone because that's going to take hours of my time and gigabytes of data transfer to get all of my media and apps back on the phone and configured.

After all my griping, I do have to give credit where it's due.  This phone is much more efficient than my Galaxy Nexus.  I left the S5 running in WiFi hotspot mode while on battery last night.  It still had over 50% left on the battery.  The Galaxy Nexus would be stone dead after about 4 hours.  I can live with that if I have to but I'd really rather be able to leave it on the charger at night.
