Screen flickering while typing - Verizon Samsung Galaxy S 4

I just noticed last night that when composing a text message, my screen will flicker slightly, like a variation in the brightness every time i press a letter. I'm not sure if this is a sign of a hardware failure about to happen or what, but i'm wondering if anyone else has experienced this? It's not a major issue it just irritates me a little. I use auto brightness but it happens even with it off. I searched the forums and nothing came up so hopefully there isn't something that I couldn't find.

Could be a few things..
Are you on a custom ROM?
Custom Kernel?
Just need a bit more info

I'm using the latest hyperdrive. I checked the known issues and it's not listed there. Doesn't mean that's not the culprit. I don't know the name of the kernel but it's the default option when installing the rom, not ktoonez. I really hope it's not a hardware problem because it will likely get worse

I'd just try another ROM and see how it looks. Sounds like it could also be the kernel or just something not jiving with the ROM.

I believe I have found a fix for this issue, go to settings>my device>display and then scroll down until you see the "Auto adjust screen tone" option and un-tick the box. Hope this helps!

[Q] Using tasker to turn off LED light?

So I am wondering if there is a way to turn off the LED lights within Tasker? I have a night profile where it turns down all the sounds, vibrations, etc etc but noticed last night that the LED light was flashing for some emails I had come in. I had a look in the tasker settings but I couldn't see any that would disable the LED?
Just wondering if anyone has any ideas?
OK, I shall keep up this conversation with myself (the voices in my head make me feel like it's a normal conversation with others though ). I found the setting in tasker to turn off the led - it's in the audio section and it's called 'notification pulse'. In my night profile I have now set that to 'off' but it made no difference and any emails during the night had the led flashing
You can use Light Flow to disable notifications at a certain time, plus you can do a lot of customisation.
You need root.

I reckon, you don't need root w light flow, but other than that bortak is absolutely right. Light flow does all that and perfectly.
Yes, you are totally right. I have installed and uninstalled lightflow a few times already. While it does do that for me, it's just not quite working right. I kept on having a notification light flashing after dismissing or viewing a notification. It just wouldn't stop flashing. That was bugging me more than the extra features I got out of the app, so I've removed it again.

this is because you havemt set the "clear notification style" parameter. set it to 'screen on'. so that once you wake up the screen al notifications are cleared and u wont see that blink again. Normally it is set to 'app entered', where you have to go to the app (or the phone and click on the missed call etc). set it to what I told to all your notifications.
Thanks. I'll take another look at that. I thought I had it set that way but wouldn't be surprised to see I was wrong. I do think that I'd tried entering the app as well when it wouldn't clear, and still wouldn't.
Hi!
Im searching nearly same. Im looking for a solution to switch off and switch on this notofication Led like i want by a tasker or by a widget 1 click.
I dont really like the app light flow.
Tasker is audio>notification pulse

Thanks rootSU. I had found that, but it doesn't seem to be working on the S3. I found the tasker google group and some similar problems exist there. One is having the same problem as me, and another I think is trying to turn the led on but it's not working; all S3's. Maybe tasker isn't optomised for this on the s3 yet?
I've found lightflow to be hit or miss. Sometimes the led keeps flashing even when the notification is dismissed (have checked my settings, even tried different ones), and the day before flashing for sms's stopped working. Even a reboot didn't fix it. So, I lived without the led's on my S1 and I'll do the same here. I had them on last night and kept waking to a notification of some kind and found that too annoying.
Thanks for the help and suggestions guys. Appreciate it.
Just a widget 1 click to switch would be perfect for me.

I think it works for me but not entirely. That ecpksind why the missus woke me up the other night to complain about the led. Hope it's fixed soon.
Once fixed Fred, you can create a widget in tasker

Don't suppose anyone's come up with any more ideas about this? I have emailed the tasker developers and I don't think they were 100% sure, but didn't think the notification pulse setting was for disabling the led's completely. I still try playing with lightflow every now and then, but the little bugs I have (mostly sms notification led not dismissing without reboot or entering lf app (only thing that works is having manual dismissal but it's a pain)) are still present for me. I also tried it with handcent but was getting no led notifications.
Hey guys,
I figured out a fix for the Verizon Galaxy S3. I know there are differences between the way the international version and US versions handle the notification light, but it might at least give you guys a starting point. You do need root.

need help jellyverse rom v0.3 i get notified even after turning off the led in the settings it blinks blue not big of a deal but does seem to drain battery after a few hours
Has anyone found a way to do this yet? Notification Pulse doesn't work, at least on the SGS3. I have tried LightFlow in the past, I found it buggy and uninstalled it.
I've been using light manager to manager my led for a while now. Doesn't have the talkback issues I had with lightflow, and free.

[Q] Voice announcements really irk me on xwlsd

Hi,
Does anyone know how to turn off the female notifications when swiping between home screens/app pages - the one that says "Page x of x". Honestly, whoever at samsung/google thought this up should be flogged. When I'm listening to music and also using my phone, I know what page I'm on, I don't need a wet nurse distracting me and telling me the obvious. Also, is anybody running into massive stuttering when quickly swiping between screens or using the dots to slide quickly between home screens? That is annoying and a drastic step back from previous roms, and also I've noticed that each new samsung rom seems to be more bug ridden than the last - either stability issues or some other annoying thing. But enough ranting, I'd appreciate if someone would let me know of solution to my first problem mentioned here - thanks in advance.
go to settings and then go to accessibility settings. There you have a option called talkback. Turn that off ~!

It's an accessibility feature. You turned it on yourself.
No I'm no dummy, that accessibility setting is one of the first things I've checked and it's off.

[Q] Flickering Multicolored Lines

For the past week or so my phone has had flickering multicolored lines flash across the homescreen(s)/lockscreen when I turn the display back on. Sometimes it will also happen if I'm sitting on the homescreen with the display already on.
Here is my Rom history as the problem began:
Was on supernexus (Android 4.2.2 I believe) - issue was not present
Flashed Unofficial Slim build 6 (wiped cache/dalvik/factory reset before install)- started having the issue
Flashed Unofficial Slim build 6.2 (wiped cache/dalvik)- issue still present
Flashed AOCP 5.7 yesterday (wiped cache/dalvik/factory reset and formatted internal SD)- thought issue was gone, but it started happening again today.
I tried taking screenshots but the issue disappears as soon as I press the volume+power button to take the screenshot. This only seems to happen when I'm on the homescreen/lockscreen, I dont think it has happened while in any other apps.
I'm wondering if this might be an issue with the specific version of the Nova launcher, as I believe that is the common denominator between these Roms (isn't AOCPs launcher based on CM's nova?). I just installed go launcher and the problem seems to be gone (for now).
Has anyone else seen something like this? I apologize if this has been discussed somewhere, I spent several hours searching Google and XDA before posting. I can post a picture later when I have access to another camera phone.
Same issue here
I have the same issue at the lock screen. Prevalent on all JB roms I have tried, carbon, revolt & slim bean.
I'm currently using Carbon nightly. I have not seen a fix for this yet. I have heard it might be an issue with the processor waking up from sleep.
After installing Go Launcher Ex opening it a couple times and then going back to using the Aspire launcher that came with AOCP, I haven't had this issue again all afternoon. Didn't have it at all yesterday though, so it might come back.
I played around with all the brightness settings but it didn't seem to do anything. Do you happen to have any pictures of the effect you are getting? I'll try and post a picture of mine tonight if it happens again. Thanks!
About 3 hours ago, I changed some GPU & lock screen settings and the issue has not reappeared.
I will post back either later tonight or tomorrow morning with some info.
I haven't taken any photos of the problem yet. By the way, do you usually experience the issue on lock screen coming from a screen off state?
ditto on this. I have Cyanogenmod 10.1 installed and I get these lines intermittently.
Try turning off CRT animations and disable hw overlays.

disabling hardware overlays always fixes it for me
same issue
Have the same issue going on had freezing and resolved that now I'm stuck on these lines multiple diff ROMs I am running cm10 I see people saying he overlays can someone provide a little more info on what that is and where to find it? Attaching screen shots of these multi color lines we speak of
Nvm can do it with the browser will edit this later and add them with a pc

Go to settings, developer options scroll half way down and you will find it. You will have to disable it every time you reboot or you can use two paid apps from the market. These apps are tasker and secure setting they are both worth every cent.

Do you have any backlight handling apps? I used lux all the time and it stopped after I disabled it.

Just enabled "Disabled HW overlay" and "Force GPU rendering". Like some of the users suggested, I found about the possible solution from this video:
http://www.youtube.com/watch?v=yhhPPke_Nbw
(go to 1:40)
I usually get the flickering with the lock screen (I use WidgetLocker Lockscreen). I was having some flickering this morning and checking both of those options seemed to immediately cut out the flickering.
I ran across it(the flickering lines) on one of the 4.2.2 roms, can't remember exactly which one but what I ended up having to do was disable one of the tweak apps it came with and install Trickster Mod only. Worked for me, no more flickering or rebooting, not sure what the cause may have been but have had no other issues after that for I believe it was 2 weeks
Please elaborate

By chance can you give some more details about this Trickster Mod like where to find it and what it is supposed to do?

Scroll down to my post there. If you still need help, just let me know.
Trickster mod I believe is mainly for Rom's that have Kernels that can be OC'd or Under Clocked. Kind of the same as Android Tweaker or SetCPU but is a little smoother for me IMO.

[Q] Display changing colors?

I bought another s4 earlier this week, and noticed a strange occurrence. Every so often, on different apps, the screen will go to more of a red tone. I found by adjusting the brightness, I can make it go to this red tone. Of course, when I try to screen shot the red, it shows up normal in the gallery. Its kinda like the blue drops out of the color wheel and red gets boosted. Is the display bad or is there some weird setting that got messed with?

Do you have Settings > Display > Screen mode > Adapt Display checked? I believe stock is Standard. There's also Settings > Display > Auto adjust screen tone. Try playing with those and see if this effect you're seeing goes away.
Yeah, I tried playing with those first thing, but didn't seem to help. I could still force the red tone by adjusting brightness

Purchased new or used? If new, I might consider returning for a replacement.
Used, from cl. It only does it if I move the brightness, or set it to automatic. I dont know if its hardware or software related, so ive tried running the me7 deodexed rom (still on mdk) and the same issue is there.

[Q] proximity sensor during calls, and lock screen notification problem

EDIT:I fixed it! turns out it was a hardware problem which occured after i replaced the screen. It was fixed by following instructions on this youtube video,called "How to Fix Proximity Sensor Issue for Samsung Galaxy S3, S4, or Note 2" ( i can't link right now because I'm new, so just look it up on youtube.) so if anyone encounters the same problem hope this video will help!
Hey guys. New to the forum I tried to do a bit of searching but couldn't really find an answer.
So I have two questions/problems I guess.
First off when I go into a call, sometimes the phone screen goes black as soon as I start the call, and won't turn back on until I hang up using the power button. From what I understand it's due to the proximity sensor always being on? But I have not been able to find a solution to this.
Secondly is, I've noticed with the lock screen notifications, when I ticked the option for wakescreen when receiving notifications, and when the screen is off, the proximity sensor is on. and when i untick the wake screen option, it goes off again.
I'm using Fusion-Boeffla Rom latest version as of now, 26-02-14 one. But this problem has been around when I was testing different roms such as temasek unofficial CM.
Any ideas how to fix this?
Thanks in advance!
1- go to calls -> settings -> uncheck turn of screen during calls.

i can't click the link, but i've seen that option in stock samsung roms before, but i can't seem to find it on my rom. And you're right, its very likely its a rom/kernel issue, i may try a different rom or even stock to see if it helps =) thanks
