[Q] Howto keep display alive while on AC or USB? - Galaxy S II Q&A, Help & Troubleshooting

Hey folks,
just picked up my S2 today and its simply amazing. One thing that bugs me though is, that the option to keep display active while on AC or USB is missing with the stock rom. On CM7 2.3.3 or 2.3.4 roms the option is present in settings, just next to USB Debugging.
Is there any other way to keep the display alive while connected to AC or USB?
thanks

You don't want to keep amoled display continuously on, especially showing the same picture all the time. Since amoled could suffer from screen burn, causing pixels which were continuously on to wear down faster and permanent ghost image on uniform colour thereafter.

Burn in is something to think about, but if he wants to then that's up to him really.
I use Tasker to do what the OP wants, although i don't do it often.

Settings>Applications>Development>Tick both "USB debugging" and "Stay awake".
But as both the previous posters have said, watch out for burn.

[Q] Leave screen on during Charge option missing

How do I allow the screen to remain on during a charge?
I use my phone for music in my car, but find it irratating when I have to constantly turn the screen on and enter my unlock pattern.
On other android devices there is the option to Leave the screen on during charging under Applications > Development.
Any Ideas on the Galaxy S2?
Kind Regards

I'm pretty sure they took this out because you'd get burn-in with SAMOLED screens...
Even if you do figure out a way of how to do this I would advise you not to. The screen can get pretty bad "burn in" pretty quickly, as I had found out with my old galaxy s.
I'm having the opposite problem the screen will remain on while charging. Cannot find a setting , four example woke this morning and left the phone in the charger returned a hour latter and the screen was still on, dimmed down but still ON.
is there a way to fix this, I'm worried about burning the screen early
This is a standard android feature that was originally found in the SGS but removed in the froyo firmware upgrade, there was no reason given but it was speculated this was to minimise screen burn.
There are a number of widgets on the android market that does the same, Widgetroid is one from the top of my head but even that's a bit of an overkill. Just install to restore the functionality.

[Q] How do I force the screen to stay on while charging on USB?

Running the newest UnNamed and I'm trying to find a way to keep the screen on while charging from USB. The point is to keep the screen on while driving. At night I charge with AC power so that's not an issue.
I found posts saying there was a burn in problem with SMOLED screens being on with a static image for more than a couple minutes at a time. I haven't seen it personally but if anyone has first hand experience with this phone or the international model, please speak up before I damage my phone.
Otherwise, once again, it looks like I need Tasker for the job. Have it detect bluetooth connection for the car and upon usb power trigger car mode and keep the screen on at ~50% brightness. something like that.
With unnamed go to Settings>Applications>Development and click Stay Awake.
Try this first,
Menu->settings->Applications ->Development -> Stay awak
If not working , try this
Menu->settings->Display->Screen Timeout ->Never
Now I've never seen permanent burn in on my SGSII or Nexus One (even while on constantly during a 10h drive to Vegas). I was using a stop watch app on my Nexus One, and while only on for 5 minutes or so, I did see it burn in, but it went away after a few minutes of being off (boy was I scared when I first saw it though).
Now, I have personally seen permanent burn-in on a Vibrant (not mine).
Funny thing is the screen timeout is set to like 5 seconds on it, so it's barely on. Yet I can clearly see the clock is burned into the screen.
Have you tried running a car app to hold a screen lock? I know Google Maps can do that. Plus it doesn't require going into settings (at least more than once).
EDIT: As a simple observation, the burn-in seems worse when it's white on a black background.

Question: Keep Screen on if plugged in

is there anyway to keep the screen on (disable timeout) while the phone is plugged in? (I liked this option with other phone's i have had for using my phone in my car mounted. This used to be under developer options on my evo and photon)
Im surprised this isnt built in.

It looks like Samsung has swapped out this option for their 'Smart Stay' option where the screen timeout is suspended while the S3 catches your eye(s) with its front facing camera. Perhaps an important consideration here is the shorter lifespan of OLED screens vs. LED screens? Google 'OLED screen lifespan' to find references to this shortcoming (As a noob I can't post links, which sucks.)

Android wear 2.0 broke dock mode

Hi all,
Since Android Wear 2.0 the dock mode while charging with clock doesn't work any longer. When placing Moto on the dock it shows a black screen. When touching the screen de clock appears for a moment and vanishes after about 1.5 seconds. It appears to be a bug. Do you all have this bug or is it just me. Did anyone tried a reset of the watch? I would really like to able to fix it , cause I use that feature a lot.
Same here.
A temporary solution I have found is to enable in developer options 'stay awake while charging' now it stays on. But it is not the same. The display appears to be much brighter. probably because ambient mode (Not sure that's how its called) is not enabled.
Edit: That appears to be the fix. When turning on in settings 'always on display' it works like before. no need to enable stay awake while charging in developers settings.
Although this fixes the issue, I am somewhat disappointed because this option reduces battery life.
I noticed I should have put this question into 'troubleshoot and questions'. I am sorry for placing it here. Perhaps a moderator can place it in the right section for me?
Not a problem here.
Always on is normally activated.

I've noticed the same behavior when I upgraded my Moto 360 to AW 2.0
For me, the clock stays on but the background is really bright whereas it used to be black before
Same thing here, background to bright. I don't think this is on purpose. They would probably get out fixed in an upcoming patch(?)
Same here.
I liked docking my watch on my bathroom counter and using it as my clock while getting ready in morning. Now it doesn't stay on and when I tap the screen I can see it for a few seconds. When it is on ....the brightness of the background is terrible.
I sure hope they fix this problem.
I have the same problem
Can't believe there is still no fix for this?
This is really annoying! I was hoping XDA had found an answer. Having always on screen on is not a solution since Moto made a bad design decision on the screen making it best to turn that option off. I assume everyone else's keep awake while charging option doesn't really solve it either because the screen turns off once the battery is full. Anyone think there's a workaround to be found in Tasker and maybe AutoInput (maybe turn always on screen on while charging, off otherwise, or even based on hours). I'm no tasker expert, so I'm not sure if that combo could work on android wear.

I have found this to be an issue when I use a charger that is not the Motorola plug that came with the watch. If you switch to the Motorola OEM charger you'll see a lag of about one to two seconds but the clock will always come on.

Not on mine. I'm using the factory charger.

I am using Motorola's dock charger. I am positive that the issue lies with Android Wear 2.0 and not the charger. Before wear 2.0 it worked as it should.
I think it's random with AW2.
After flashing a new rom at my mobile, I had to forget and pair again the watch to the Android wear.
From now on, the clock stays on during charging.
This was not the case before that.

I have the very same issue (watch paired with a Nexus 4, 5.1.1). Anything I can try? Thanks!
Well, at least this is validation for me. It's been driving me insane, and I'm almost positive it's killing my battery life. I used to be able to stretch a full week on a single charge, but now it's more like a full day.
I'm sure this is what everyone else has been experiencing: there is now a setting called "Always on screen" in Android wear settings. The new behavior for this setting is a strict enforcement of this property; that is, to be either always on or auto off. This seems absurd because before Android wear 2 (not sure if the option existed or not), it seemed to work as we expected, to auto off in active wear but stay lit while docked. There should at the very least be another mode for when docked/standby vs active wear.
Something else that makes it seem buggy is that when the always on screen option is disabled, and the watch is docked and charging, the screen is still faintly lit although only a blank black and no clock. I do think this is a bug and not a feature. For anyone interested, there are also settings for other things you might not be using. I'm turning them off and pray the battery gets better.

What r u talking about?
Always On was there since Android Wear 1.5.
And come again?
1 week use of the watch with 1 charge?
How did u manage to do that?
By turning on the watch for 2 hours every day?

Question Is it possible to lower the brightness of the charging LED?

It is quite bright, especially at night. Is there a way to control its brightness?
My Xperia 1 III is rooted if that's needed.
Thank you.
I just put the phone screen facing down
This is a technical forum and expects technical response to the asked question.
That's weird. My xqbc62-v notification LED is dim and has a narrow viewing angle. I can only see it at night.
I think there are multiple hardware revisions of this phone. My first phone was purple and crashed constantly. I returned it and bought a new one later. It's purple, but so dark that it looks back except under direct sun.
I see what you mean now. The BC62 notification LED used to track ambient light and it was always relatively dim. Starting with the Android 12 update, it's max brightness all the time. It's annoying at night.
Yep I can confirm that the LED is much brighter after A12 update. I charge the phone wirelessly at night beside my bed so putting it face-down is not an option. ;-)
What I have found to work is completely unscientific but works every time for me. I use a cable so not sure if it will do the same for wireless. After I plug it in I too notice that the LED is too bright. So I wait a minute or more and unlock the phone with my fingerprint (while the charging cable is still plugged in) and then double tap the screen to relock the phone. I use Nova Prime as my launcher which allows me to double tap to lock. Usually doing this makes the LED dim down considerably. Sometimes I have to do it 2 or 3 times but it always ends up working. YMMV
Anyone knowing a 2ay to disable the LED while charging? Maybe via adb command?
