Since we need to have the screen turned on to keep wifi/gps etc. running, and there are a few apps that would ideally run in the background with the screen off; to save battery power (and burn in?) it would be nice to have the AMOLED screen display just a black image.
Is there any app out there that just displays a black screen and maybe ignores all but a specific input?
At the moment I just zoom into a black image in the browser, but I can't put the phone in my pocket like that.
(I tried searching for this, but it was beyond my google-fu.)
You dont have to keep the screen on to run either my gps is always on and it neva disconnects also ive spent many nights going to sleep leaving my wifi connected and its neva disconnected either
Yup. If you haven't set WiFi to switch off after 15mins, it should carry on running.
By doing what you proposed, you'll decrease battery life drastically as you'd effectively be disabling the chips sleep mode by keeping it running 100%. With that, only the screen switches off and everything else including Android keeps running. Any application holding a partial awake lock can achieve this.
Lock delay; an app to control the default screen-lock options allows this.
For instance, if you set the initial screen timeout to 2 minutes but standby/lock to 10 minutes in the settings, the screen will switch off after 2mins idling, but the rest of the phone will still be running incl. WiFi/GPS. You can enable a lock/pattern or no lock at all where you press any key including menu/trackpad and it'll come back on in the same place you left it, without any lock. If the phone idles for 10mins, it'll activate the screen lock and place the phone in the standard sleep mode. The max delay you can set the latter to is 24 hours.
I wouldn't advise avoiding the sleep mode unless required in specific circumstances. Battery loss will be drastic; I found out unintentionally when activating this option at the beginning.

Thanks th3, that should do what I want. I don't intend to leave it unattended, it's just for when don't need the screen on while an app is doing something.
I'm sorry to ask something so seemingly simple, but I've scoured the settings in my phone, as well as checking solutions like tasker, and have yet to find a solution, and searching for similar threads.
Prior to going into a lock/sleep mode, the phone's screen dims for a few seconds. If the phone is set to stay awake while powered by AC/USB, the screen will still dim, but not lock. How do I go about completely disabling the dimming function, as this is troublesome when using the phone in the car?
One of the aokp ROMs allowed for adjusting the time of dimming such as 15/30/45 but did not disable it.
Also in developer options on custom ROMs you can enable stay awake so the screen never turns off while charging.
Otherwise I saw from internet searches there are apps on the play store that will prevent screen turning off and possibly dimming as well.
****edit***-i read a bit more closely. Sorry, looks like you may need an app. If a dev is willing the option is controlled from android source and can be modified using a toggle to turn it off. Good luck!

1. Go into About found under Settings, click "Build number" 5 times to enable developer mode.
2. Now swipe back into Settings main menu and select Developer Options.
3. Enable Stay awake when charging.
Beware, this doesn't appear to be reversible. Turned it off, screen stays on when charging. Reset the watch, screen stays on. Makes charging much slower.
EDIT: Actually appears to be part of an update, will always stay dimly lit now.

Just found that out myself as well. It's tough when a device is so limited. Not much info out there yet
Wait, its supposed to go off when charging? The damn thing stayed on all night last night for me (first night with it). I thought it was a feature. I took it off several times and it stayed on, even when I pressed the power button. I'd really prefer it not stay on.
I enabled dev options and its not set to stay on. Weird. I'll check again tonight. When i first opened it and did the initial charge it did turn off but I thought maybe since the ambient light sensor saw it was night time it stayed on but goes off during the day. Weird.

I've noticed there's different modes of dim too. Sometimes it's very dim, and at other times it's somewhat dim. Really strange. I turned the watch off and put it on the charger. It automatically turned off, but stayed in a very dim mode compared to how it was when I just put it on the charger without turning it on. I am slightly worried about burn in rather than charging slower. Since I'll be charging overnight.
I wish there was a way to turn it off or at least turn down the brightness, I like my room completely dark.
Can't find another question like this one... so here goes:
Just got a Moto 360 for 149.99 USD and its great so far.
Did that force update to 5.1.1, this one worked for me: https://www.reddit.com/r/moto360/comments/3ahj1l/a_surefire_way_to_force_the_511_update/
Now I look into turning off the screen when its charging, only to run into a very strange issue...
In the developer options, which you can enable using 10 taps on the build number in about, there are two options:
1) stay awake while charging
2) burn-in protection
Burn-in protection will NOT save the check when your restart, so in essence, is useless.
However I found that using stay awake while charging DOES indeed turn off the screen, but here's the catch: you have to set it to ENABLED.
Don't believe I have ever seen a setting on android that required it to be on, to be off...
But hey, it does work, on mine at least.
Also the whole "just hit the button to make the screen go off" ONLY works in Theater Mode! And I personally dont like pushing a button to check the time.
If Theater Mode is off, it will just brighten the screen for around 2 seconds, then dim again.
Here's my question, what does that burn-in protection do anyways? Just pixel shift over time? Why can't it be enabled?
Hope this helps some people!
that setting does nothing for me
the screen stays awake regardless of ENABLED or DISABLED
funny how motorola hasn't fixed this yet
just put watch in "Theater mode" before charging
and it would switch the screen off on charger too

It started on mine, in the dock. Every few minutes everything on the display jumps in size from small to large and vice visa
The staying awake feature is backwards. Crazy
Sent by entanglement.
I restarted mine after setting to enabled, also ambient / theater mode are both off.
Hi,
as ShadowVlican wrote: just enable the theater mode to switch the screen off during charging. It is also important, the you undo any changes you did in the developer menu ("stay awake while charging" and the "burn in protection" as well).

Yeah, no. My screen turns off for 10 seconds then just becomes dim black with backlight again.
Is there no damn working solution?!
I have auto dimness unchecked, and whenever the brightness is set to over 55%, after unlocking the phone it always auto dims byitself.
Is this normal? no other phone does this. Can this be bypassed somehow? It's jarring when you unlock and see a bright vibrant screen and all of a sudden it dims like 10% or so after 5 seconds.
Phone auto dims when it starts to heat up regardless of your settings.
Otherwise it shouldn't as long as it's not set to auto brightness.

Ok, but when the phone hasn't been used in 30 minutes, and not "hot" at all, this still happens. This also happened with the G3 as well.
Is there a way to turn this off? This post has over 100 views, can everyone please comment if their screen does the same thing? Are there any solutions?
What carrier/model do you have?
I just tried this on mine, Verizon, 611A software.
With Auto Brightness disabled, set to 40%, I powered off, turned it on, then unlocked. The brightness did not change. Then set it to 100% brightness (Auto still disabled), and did the same thing. Again, the brightness did not change.
I have, however, seen the screen brightness reduced when I'm using Auto Brightness. If I turned it off in a bright area, then unlock it in a dim area, the screen will be bright for a moment, then will turn itself down, presumably based on evaluating the current ambient brightness.

auto brightness is always off. It's the AT&T non rooted stock version. I just tuned brightness to 70%, powered off, powered on, and after unlocking and opening chrome it auto dimmed within 5 seconds.
Does it do it if you don't open Chrome?
I've seen apps make their own brightness adjustments (like a camera app that maxes out the screen brightness when it starts up). I want to say that Chrome (on my last phone) is one of them. Alternately, turn it on, unlock, wait 15 seconds, THEN start Chrome. If it still happens right after Chrome loads, then it's a Chrome phenomenon, not a just-turned-on phenomenon., and at least you can isolate what to chase down.

Yes it dims even if I don't use chrome. No matter whats on the screen it dims a little after 5 seconds.

Download LUX (couple of bucks) set it to manual, 100% brightness on all LUX setting areas and it will bypass LG's lame attempt to hide the fact that they can't make a phone that doesn't suffer severe battery drain and overheating.
Your problem is called High Tempurate Thermal Mitigation (throttling). I depise it but with LUX, I tell the phone what is acceptable to me, not the other way around.
If I wanted to be dictated to like a submissive I'd just get an iphone.
I don't doubt that excess temps can cause the phone to adjust its behavior. But that quickly after turning the screen on? That seems really fast for something to go over-temperature, and for a sensor to also detect it that quickly. You may be 100% right, it's just not something I'd expect to happen that quickly.
This is a serious suggestion, despite how it may sound What if you put the phone in the fridge for 15 minutes or so, then do the same test? Does the screen still dim after 5 seconds? Depending on the humidity level, the phone could start to condense after coming out of a cold environment, so use your best judgement.
For a "safer" test, hold it in front of an air conditioner for a few minutes, with the screen off. Then, still at the A/C, turn the screen on, and see if it immediately dims.
If it suddenly runs for a while before dimming, then I'd agree it's likely temperature-related. If it still behaves the same way, then perhaps it's a different cause.
Either way, Lux sounds like a nice addition to these phones, from everything I've read. I've just been too cheap to try it yet But the rather coarse auto-brightness from LG has me curious.

Have you tried the cool-down suggestions (fridge, A/C,) ?
Try installing ThermoCF to monitor the battery temperature. I find that when used for GPS (mounted on windshield) the screen will dim with direct sunlight. The temperature is in excess of 120 °F when this happens.
I just left the G4 screen on 50% brightness for about 5 minutes and the temperature remained 98 °F (this is on a wireless charger, next to a warm laptop fan exhaust). I switched to 100% brightness and the battery temperature increased to 100 °F over the next five minutes but no dimming has occurred. After a few more minutes the temperature dropped to 99 °F with the screen remaining at 100% brightness.
Different from your problem but: I turned on the developer options and set the screen to "always-on when charging" and have noticed that the screen dims after some amount of time (I haven't timed, maybe 15 minutes or so). I ended up here because I was looking for a way to change that time and may download the LUX app to do it.
Nice to know I am not the only one having this problem. I use my phone to play Ingress and sucks the battery dry faster than anything. The screen kept going dim as I was charging.
I also have this same issue on my G5. I've tried the Lux, free version, and it still dimmed on its own. I wonder if the paid version will help out my situation?

I like the auto-dim, and my phone seems to accept manual "guidance" as to how I prefer the auto-dim to work.
What I mean is that I can manually bump up the brightness slider (while auto-dim is checked/enabled), and the phone will auto-dim using the brighter setting. Or, I can bump the brightness slider down, and auto-dim will remember that and adjust the brightness.
So it's like you can control the baseline setting for auto-dim by using the brightness slider with auto-dim enabled, and then the phone will auto adjust from that baseline. I play ingress and during the day I bump up the slider, but during the night play I'll decrease the slider and still enjoy auto dim both ways, and preserve the most battery that way.
Aint looked to see if g4 has got it. I know g3 you go into hidden menu. And turn the thermal mitigations on and it stopped the throttle down. Lg has an insanley low throttle down temp.

On the g3 and g4 its under main hiden menu. I use shortcutmaster to get to them all. But the g4 the options not there. Im not sure i dont know anything about the g5. Im not interested in it at all. I am selling my g4. So i can get another g3.
Now i know theres an app 3ctoolbox. And in cpu settings you can modify the unclock temps i dont know if it does the screen.
So, the hidden menu in Marshmallow, here it is folks. Where would I be able to find the option to turn off screen dim do to thermal mitigation? Anyone have any ideas?

Mine also started to auto dim with auto brightness off. I have the H812 from Bell . I'm sure that on mine it's the proximity light sensor that is faulty or in the software. Because when i turn on the phone while blocking completely the proximity sensor it doesn't dim anymore. (knock knock doesn't work while sensor is blocked) but problem comes back if i wake up the phone without blocking the sensor. I have tried it many times and it's the same thing over and over.
Calibration in the hidden menu doesn't fix it, Lux and many other brightness apps iv'e tried don't fix the problem lol
I also use lux with cf.lumen
Lux will manage the auto brightness as per your preferences because i found the stock LG screen was about 15% lower than id like in all environments.
Cf.lumen actually changes the colour of the display rather than applying a dumb screen filter on top for night viewing.
The only thing Lux does for me is dim the screen twice since the phone already dims by itself 3-4 seconds after the screen is turned on. I can guaranty it's not an overheating problem, even after 30 minutes in the fridge it does it. I'm tempted to have the proximity sensor changed but will most likely wait for LG to release 6.0.1 to see if it will fix it.
Nougat 7.0 is days away and still no 6.0.1 MM for the G4. Pardon my language but LG really sucks . This is my first and last LG phone
