Lcd dim issues

I'm having issues where after going to sleep, it wakes up with the lcd very dark. It doesn't matter which level of brightness I put it on, the lcd is still hard to see. Rebooting solve the problem. Just wondering if anyone experienced this too. I hope it isn't my lcd dying...
This happen on both froyostone and bangster. I'm on the latest radio using tmousa.

I had this on bangsters 1.2, but haven't seen it on 1.3b, but only been running that build for a few days.

i had this a few times before on a shubi build. I came to the conslusion that it is the screen not fully coming out of sleep. Seeing as it only happened when I put the phone to sleep and then tried to wake it immeadiately or got frustrated and impatient with it and tried tapping buttons repeatedly until the screen came on.

I had this same experience. Patience is a virtue with these phones. As long as I wait if its taking a bit to come out of sleep, I get zero problems.

thanks for the advice. I hope its just a software glitch. I will just have to be more patient when coming out of sleep.

Here is my solution, i posted it in a similar thread, I think the key element here is the bsb tweaks part, hope it helps, thanks:
I solved this problem in my phone.
even turn on/off/on/off/on/off etc the screen, the devices wakes up correctly every time.
I don't really what exactly fixed but.
i installed Miris romm 20.0, then i turned off the auto screen off *start/system/power, so the screen nevers dims or turn off. I turned off the charge the device when it is connected to the computer, turned off quiet pickup, turned off 3g.
and now i think this is the key, installed bsb tweaks and turned off everything(even power savings), disable data connections and screen rotation, I only left use high glymp cache. reboot and run android, in winmo i dont have anything installed besides bsb1.6
in android i have the task killer on and set cpu at 768mhz ondemand. no profiles. battery last well over 24 hrs moderate use. by the way im using shubcraft, and the gsensor disabled kernel. thanks,
edit: also my auto sync is off in android and my wifi is always on.

I dealt with the problem by putting a widget to control screen brightness on my home page, if it goes dim I can find it ' blind'

Yeah it does happen to me if I'm being impatient and banging on the screen before it fully wakes up. Haven't found a real solution yet, but so far I would just try my luck by turning on/off/on/off several times, hoping that it get stucks momentarily again to let if "fully" wake up. Worst case scenario, reboot.

IN MY CASE, THE SCREEN NEVER TURNS OFF! ONE TIME, I left out alone without my phone and three hours later I come back and the battery is 20 percent and the screen still on.

For games, the publisher needs to fix it and add permissions to keep the screen on.

it may be annoying playing NFS:S but just tap the break when you see the screen dim a bit

[Q] Screen Timeout 2 Second MaDnEsS...

I got my 32GB AT&T Galaxy s4 one week ago today. Had to make an 8 hour road trip to get one but I would say it was very much worth it. I am having this maddening problem where a couple times a day the Display screen timeout keeps re-setting itself to (2 seconds) Unbelievably frustrating considering I can barely get the screen unlocked in 2 seconds and if I blink I have to do it all over again.
But wait, don't walk away just yet, there's more! I have already factory reset 3 stinking times trying to get to the bottom of this and when I woke up this morning it was back to (2 second). Furthermore it shows (2 seconds) in brackets like that so I assumed this was the default value but after checking just now while I was typing this post I noticed after changing it back to my preferred 30 seconds that the 2 second option vanishes. I'll snap a screenshot next time this happens.
Anybody else seen or heard of this problem? I assumed everybodys was doing this until I started searching and found 0 others with the problem. Is my phone The Chosen One?

Yes, i have it also and i found some forums where they discuss same problem, but no solution . Let's think what we have in common..
I have this app called Light Flow, do you?
Also which things you have on?
I have nfc, snart view, smart scroll, air view, air gesture

Absolutely have Light Flow. I never leave home without it.
NFC. Yes
Smart View. No
Smart Scroll. No
Air View. Yes
Air Gesture. Yes.
I thought for sure it must be Smart Stay malfunctioning but I don't even use that.

maybe it has something to do with Light Flow?? this app caused weird bugs sometimes...
wanna try to turn it off for a while and let me know if it helps?

Worth a shot. I'll play with it and see. Thanks for the idea!

I'm having the same issue and I also use Light Flow - any developments?

Work around
Guys, Did yo get this sorted? I had exactly the same problem which has been driving me mad but managed to sort a workaround which works perfectly. Let me know if this wasn't sorted and I'll post it.

I turned off "Power Saving" mode and it hasn't done it since.
EDIT: Nevermind... just had to give it more time.

Would you kindly post the workaround? I'm out of ideas at this point.

You all have LightFlow. LightFlow causes other odd issues with Accessibility settings with the S4. Get rid of it and for now use Light Manager. Its much better IMO because it doesn't need to be activated in Accessibility settings, it just works.

Well, I didn't have power saving on and was still getting the problem. I uninstalled light flow and still had the problem. To resolve this for now I use an app called tasker, I had it already because it is a very cool app anyway but once installed if you don't have it just create a rule to deal with the time out issue. My rule for example went like this.
If the time is between 00.01 and 23.59 then set display timeout to 2 minutes. This fixed the problem for me.
In fact you could create other rules to do the same but this does it nicely.

I set my rule to set the display timeout every time the display is turned on. I couldn't make it work the way you did it. I think I need more expertise.
Thanks again.

I haven't seen this issue again since starting this thread. Go figure. I haven't changed anything at all either. Still using lightflow in its entirety just like I was before and never changed anything else that I can recall. Weird.

Ok, I think I have this issue figured out. Here's how I resolved it:
1. Open Light Flow
2. Open Settings
3. Scroll all the way down to the section "Additional LEDs found"
4. Deselect "lcd-backlight control' and exit

I have the same exact problem.. Tried everything but with no luck!! Any one figured it out!??

Just to let you guys know, i was able to fix this problem but with a sacrifice.. I reset my phone to factory settings & reinstalled all apps except for Light Flow (The problem did arise after i installed it) and now the screen times out perfectly with the duration i set. :good:
I just hope Light Flow fix this issue soon because i got used to the LED lights indications,, they were very useful.

Solution (I hope)
It's light flow's turn on screen option. They're patching it in the next update, but for now all you have to do is uncheck switch screen on in the notifications.
I tried this tonight. Will post back confirmation from the link
I just registered so I can't post the link to the forum I found it on.

Screen timeout
So I have a Galaxy s4 and started having this same issue with my phone. I would set the timeout for 3 minutes but it would reset back to 0 after so long. I dont have that application you all are talking about. I did root my phone which I do not think matters.
Essentially there are 2 spots to change the screen timeout I found.
My device>Display>Screen timeout
and
My device>Accessibility>Screen timeout (which was set to 0 even though the other was set)
I will let you know if this resolves the screen timeout issue for me.
Thanks

I also was having the same 2 second screen problem and found the unchecking the (turn on screen) to (Switch the screen on for 5 seconds when the notification arrives) in each of the notifications in Light flow has solved my problem. It seems that it was the cause of resetting the screen time out to 2 seconds.
Can someone else try this and confirm that this is the cause???

[Q] Screen shuts off trying to unlock

My friend just got a G2 and is having this issue as well. I use a pattern unlock and am running Clean Rom. Some times when I try to unlock the screen it just randomly shuts the screen off while Im trying to draw the unlock pattern. I'm hoping someone has a solution for this.
Thanks

When I use the power button on the back of the phone instead of the knock-on, I had this same problem. I was rooted but on stock rom. I've read other posts about the same problem. I would try to put in my pattern and midway through the screen turns off. Sometimes it would be two seconds, sometimes like 10. Don't know what the problem was.
My knock-on feature was barely working. Some guy recommended getting this case: http://www.amazon.com/gp/product/B00FEQU1NG/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
I needed one anyway so I got it. Haven't had an issue with the knock-on feature anymore. No idea why haha but whatever, it works. Kind of a ghetto workaround.

I'm having the exact same issue.
Factory reset several times, installing my usual apps or having just the default apps without updating them didn't make any difference.
After a factory reset I disabled the knock knock feature and still, when I try to bring my screen up and unlock, it immediately shuts off, preventing me from swiping.
Another side effect is, when I make a phone call, the screen immediately goes blank and it will never turn back on unless I restart by holding on to the power button, this is especially inconvenient when I need to dial some options (i.e.) voice mail options, corporate automated options.
All of the above happened while I had my Incipio feather shine case. (incipio.com/cases/smartphone-cases/lg-smartphone-cases/lg-g2-cases/lg-g2-cases-verizon/feather-shine-case-for-lg-g2-verizon.html) I took the case off and did another factory reset last night, and so far the knock-on rate has improved from 0% to at least 60-70%... Strangest thing.... If anyone else can shed some light onto what the hell happened/is happening, I'd really appreciate it! It's been a frustrating ride since this problem surfaced about a couple weeks ago. I had this phone for about 2 months now....

I'm having this problem too. It happens with both knock on and power button wake. I have noticed that the screen is not actually immediately turning off, though. In a completely dark room, I can still see faint outlines of my lock screen. Then, after the brief time out for dimming, the screen will go to its dimmed brightness (which is far brighter than what's concurring after waking the phone). I'm able to unlock, reboot, and usually that will solve the problem for a little while, but this is getting frustrating.
Stock rom, rooted, TWRP, Nova Launcher, and xposed. I'm not sure what's causing this.

I know it's been said many times but if you block the sensors with your fingers after waking the device, your screen will turn back off. Its a security feature/bug and I would assume this is what's happening here.

I ended up getting a certified-like new replacement from verizon... While I had the old one, I did a test with that sensor you're talking about and it didn't really make a difference. I made sure the sensor area was clean without anything covering it and the problems persisted. I really hope LG can find the root cause of this and fix it... Very frustrating.

Not a bug. But this is a feature we do not want. It is called proximity sensor. It is sensing too far imo. It is actually the one next to the front cam. Dont block it within 5 inches in front or you phone will sleep again. That should work with flip case. Annoyingfunction imo. Your device is not broken.

exactly. the sensor in very sensitive to being covered. Because its hypersensitive and having undesireable effects I would consider this a bug since it is buggy.

I figured out what the issue was, at least on my phone.
Lightflow was detecting a bunch of alternate LEDs, which I felt inclined to tick the check boxes for, just to make sure it could control the LED fully. Having those boxes checked caused my phone to do this. Everything is fine since I've unchecked them, though. No sensor issue, no proximity/case issue, just Lightflow (which still works without those alternate LEDs checked).

Having this issue with my G2, its very annoying. Knock on does not work and screen shuts off after about half a second that I press the power button. Had to reflash to stock the first time this happened and fixed it but after about a month the same problem occured. I could however open by pressing one of the volume button together with the power button.
Hoping to find permanent fix for this problem.

Always on display turns off after a while.

i noticed after a while my always on display turns off. is it supposed to do that even with good battery.

I also noticed that, but i had it in my pocket and after taking it out the always-on screen went on again, if i did not press the button while taking it out. But as i actually have the phone in a clear view cover, and there the always-on screen is deavtivated completely, i cannot say for sure.

My phone did the same thing the other day. Once I picked it up the display came back on.
I figured the phone was sad because I wasn't using it. LOL.

So after the night the display was still on. So just laying on the table did not turn it off. But i got a dead pixel over night. Well not really as the red pixel is only shown on the always-on display. As soon as i turn the phone on, the red pixel is gone.

there is a option in the settings that puts the screen completly off when it`s in a pocket or in the complete darkness since it`s using the light sensor on the phone.

I found in mind the feature fit toggled of somehow and I had to turn it back on. Not sure why.

Where do you find this setting?

Settings->Display--> keep screen closed(or something like that)

In my case, the actual setting for always on display keeps toggling OFF. Same for Edge Screen (Edge Panels). This has happened about five times since I bought the phone last week. I can't correlate it to anything like low battery or permissions. I guess a conflicting setting or app could be the culprit though. This has happened a few times even when I'm not using the phone for a short time. Any thoughts?

My S7 edge is doing the same thing also. In my case the Always On toggle is still set to on. I have no idea why the screen is just `turning off`.
It's a shame; I really got used to the always on.

Just a follow up; I determined why AOD kept turning itself off. Apparently dust or grime got between my tempered glass screen protector and the screen. Once I removed the tempered glass protector, the AOD began functioning again.

The same!

Don't know why, but the same happens to me, just randomly??

Mine S7, now with Oreo, also turns Always-on off it self. Maybe in connection with App updating or?. It has done that several times now.
Don't mix this problem up with Always-on turns off for power saving when screen is covered - in a pocket or face-down..
