Screen noise/flicker upon turning screen on
Upon turning on the screen, there is a slight flicker/staticy looking noise. Toward the bottom of my lock screen. It's easily replicated, but it doesn't do it every time.
I just want to know if it seems like a defect or it could easily be fixed by an update. Motorola might not even know about it yet.
Yeah mine does it sometimes, but not all the time

I'm getting that too.
I filmed mine in slow motion when this happens on it and it appears to be an android software bug. It flashes the home screen then pulls up the latest app or vice versa. its so fast it looks like its just noise though.
you guys sure you didnt turn on the option for it to make a noise on unlock?
Are you guys or anyone else having this problem while being rooted? Because, I only started noticing this problem after I rooted
It happened to me before being rooted, if I had Moto Display on it never showed, it was only until switching to Ambient Display, or to neither Moto or Ambient Display that it started showing up.
Always running Notification
May be because of any always running notification. I too had same problem. Then I uninstalled the app that always used to have a notification running. Now the problem seems to be less frequent or not anymore.

I've owned 3 of these so far (on the 4th... let's not even go there for now)
The newest one seems to be fine overall -- but I'm wondering if this is common among other GTs--
Problem:
Turning off the screen, and then quickly turning it back on causes the backlight to start, but the screen remains black until the power button is cycled again.
Here are the conditions under which I've experienced the problem:
GT 10.1, 32GB, Gray
Screen brightness ~40% and 100%
Lockscreen and Homescreen wallpapers set to Gallery image.
It has happened to me a few times, but not often enough to bother me. There was a topic about this soon after the release and I believe the problem isn't very rare.
I'm going to be at Best Buy later today anyway, so I'm going to see if I can replicate the problem on their display models.
It's quite annoying... Could someone try to see if they have the same issue on their retail model for me? It shouldn't be difficult to. It happens a lot, personally.
Ive been trying to replicate it but no luck. not sure if it matters but I've got a pattern lock screen.

Ever since as long as I can remember, my phones brightness will dim to a brightness so dark you just can't see it. Even if you manually set the brightness, once you lock and wake the screen, it's fine then suddenly switches to dark.
I've used multiple ROMs and they all do it. Is it a device issue, or could it be a kernel issue? I've not screwed with kernels so I don't know if it could be it. If it's a device issue, I'll be getting a replacement ASAP.
Any help is appreciated!
Now that I'm able to Google, I realize it's a common problem with the S4.

The only time I had the screen go dim like you describe is I remember once following a phone call. It goes dark when you put the handset to your ear like it's supposed to, and lights back up when I pull it away from my head. I was stepping out of a truck into the broad daylight when I tried to hang up my phone, I couldn't see the screen very well. The other party ended the call, and my screen timed out while I was squinting at it. I pushed the home button and it lit right back up nice.
You got something going on, and if you tried all those different roms, say... can you nandroid back to stock? Did you try that?
I'd try everything I could on the outside chance of repair instead of replacement. If you get a replacement you might be stuck with that MF3 where you cannot install a custom recovery.

Mf3? Is that something new with the S4s to prevent custom ROMs?
It does not go pitch black. It goes very dim every time I wake the device. If you Google S4 screen dimming it's a wide problem.
Once you wake it, it's fine for 2 seconds and dims quite dark. It is not screen timeout/sleep/etc since I can still see the screen.

I'm on MDJ and don't get any auto dimming of any sorts. Auto brightness is off, brightness controls about 1/3 brightness (indoors), but Power Saving mode is on with all three options on.
My S4 is MDL. I found out the problem (More than likely) was the Paranoid Android ROM. I was on ver. 3.69 and since switched to CM 10.2 Nightlies, latest as of today, and no screen dimming. I will install my usual apps and use it as normal and if it happens, it's probably an app. However, the only apps I use are ones such as SwiftKey, LightFlow, ASTRO, Chrome, and Dashclock.
I'm on stock MDL. It has only been occurring since I upgraded from MDB 3 days ago, and is a huge PITA because brightness controls are unresponsive during this time - I go into settings to adjust brightness since I have removed all the brightness controls from the notification panel as they've always worked just fine, and turn off auto brightness, scale it all the way to max, and it is still dim as crap.... Only fix I've seen is to reboot, which is obviously not ideal in most situations when I need to wake the device! I'm using STOCK kernel, STOCK ODEXED ROM as well, nothing crazy should be going on to screw with brightness settings being unresponsive either!

Do you by chance use Light Flow?
I solved the problem. I had "lcd_backlight" control flipped on in the settings of Light Flow. It fixed it. To tell if it's an app problem, just factory reset and try, once you boot up, to lock and wake the device to see if it happens. If it doesn't, it's an app problem more than likely, or even a general setting. Troubleshoot for the win!

I do use Light Flow, but I don't have either one of the LCD Backlight controls enabled, never have and never will, so I don't know how that could be affecting my phone at all.... That's a good start for some, but not for me, unfortunately! Good catch though

I had this issue before on my Galaxy S3. I ended up replacing the front glass because of a dead pixel. Come to find out I had a sensor issue and that was causing my brightness auto going to whatever level it wanted.
Perhaps you're experiencing that too. Haven't heard or read of any sensor issues yet with the S4 but you could be the lucky winner!
My biggest source of frustration right now is how inconsistent Ambient Display is. I suppose I was spoiled with the Moto X because it worked without fail all the time. On stock android Ambient Display just sort of comes on when it feels like it, but it's even more inconsistent on this phone than it was on my Nexus 6. It's to the point that I don't even rely on it, I just go straight for the fingerprint reader or power button because otherwise, I end up just looking at a black screen 98% of the time.
This applies both to when I have notifications and don't. Sometimes, I'll pick it up and it'll show me the time. Other times, nothing. I pull it out of my pocket with a notification, notification light blinking and everything and the screen never comes on until I hit the power button or scan my finger.
That is frustrating. I was hoping to notification on the home screen "light up" like they do on the iPhone. I find this feature useful when I'm driving. Are you saying you have the feature enabled and it works intermittently?
Mine hardly ever works like it should...

Hopefully a software update will fix the issue.
Same here. Coming from a Turbo I miss it...I wish we could use the proximity sensor to activate it...
Same here. I hope some custom rom may bring moto x like active display.
Ambient Display is totally fubar on my 6P; no notifications whatsoever, the phone is sitting on my desk, and it just lights on and on and on wihout any reason.
That's bizarre...mine works 90% of the time as expected.

Have a feeling you have an app installed that controls the led, ex lightflow or light manager. If so disable said app and this will stop happening.
At least that was the problem in my case..

I dont have any LED control apps installed and mine does exactly what wewewi999 is saying. I will hear it and look, nothing happens. If I pick it up, it ONLY activates Ambient Display with it is completely vertical. If it goes away and I want Ambient Display to activate again, forget it. I basically have to do the twisting motion that I used to do to activate the camera on the Moto phones to get the Active Display to turn on.
Currently, I have an unread notification. Ambient Display activated instantly, then pulsed once after about 5 seconds. Then pulsed again after about 10 seconds. Still unread, it has stopped pulsing altogether? The next notification, it didnt pulse at all. Random.

Mine does exactly this. It's been irritating me. I've tried uninstalling apps, clearing cache and still it occurs.
Shame because I like the ambient display feature. Hopefully a software update can fix this.
If you find a solution do let me know.

Coming from a Droid Maxx I am so used to just pulling my phone out off my pocket or lightly nudging it when it's sitting on the desk and having the time (and any recent notifications) show up without having to do anything else. With the Nexus 6p, just as others have said, it's so random that I can't even figure out how it's supposed to work. Surely this is not what they intended. I really hope they can and will fix it.
Seriously missing Moto!
Mine seems a little better with the notification led off. Can't say its perfect as I'm used to Moto's awesome implementation, but its definitely better without the notification led on for me.
I think it's Doze. My Nexus 6 was very sensitive until I updated to Marshmallow. It still responds reliably when I pick it up, but it is less sensitive to nudging and of course notifications are delayed because of how Doze works.

Mine wasn't working well, so I installed AcDisplay. It now works much better. Not sure if it is the app or the setting that is making it work, but it is now working well enough to make me feel like compares to my old Droid Maxx.
I realised that the tempered glass screen protector I was using (which had no cutout for proximity sensor) was the trouble maker. I knew the protector was already causing trouble while receiving/disconnecting calls but had it for the time being until I got a correct one. Now that I removed the screen protector the ambient display works flawlessly!

I wonder if we can turn off battery optimization for the app or service which controls ambient display? Anyone know what it is called?

so your using AcDisplay instead? Or AcDisplay improved your ambient display somehow?

Yeah my screen protector has the cut out too and I've never really had a problem with ambient display. Tried a Moto x Pure before and it pretty much works just as good.

I tried AcDisplay yesterday and its useless if you use the fingerprint scanner to unlock. AcDisplay is just another loop to jump thru to unlocking the phone. I will admit though, it DOES work MUCH better than Ambient Display. Much more sensitive.
Whenever I unlock my device the screen turns on noticeably slow, it's like it's trying to transition but it isn't smooth so it feels off.
What is strange is that this doesn't happen when my phone is tilted at a <45° angle, it just powers on almost instantly with no slow transition. Anyone have a similar issue or know of how to fix this?
Edit: I take the angle back, it seems to be ambient lighting based. Still not sure how to disable this "feature"
Mine is extremely fast

I'm guessing it's purpose is so it doesn't turn on too bright in dark or dimly lit rooms and allows your eyes to adjust. Which is a nice feature now that I think about it, I've been blinded by previous phones numerous times when I turned them on at night. I don't know though, it just lacks a certain smoothness that the device's other animations have.
What bothering me the most is that we can't adjust the brightness on the always on display... is too bright

In display settings you have an option called "keep screen turned off", which prevents the screen turning on accidently in dark places such as a pocket or bag.
Hi,
I have this phone for little over 2 years. For over 1 week now I'm experiencing my phone not being able to wake up when I use the power button/home button. Whenever I push the button, the screen flashes for like 1s blue color, you can also see that the notification panel is blacked out and part of it green and it doesn't wake up. Sometimes it doesn't even flash. It used to take about 10 tries to wake it up but today I couldn't wake it up. I performed soft reset, I couldn't see the booting animation at all but it rebooted, buttons lit up and I was able to get in. It's like the phone is working fine in the background but the screen doesn't light up. I can turn down/up the volume, take a screenshot, get into settings, open apps, write a message but the screen is black. Even my alarm went off this morning but I couldn't dismiss it.
I downloaded an Always On Display app. Although I don't actually see the screensaver when it's locked, it's still on and it's easy to get in beacuse of it.
It all started with the screen flickering on minimum brightness. In February this year I had the screen replaced for the same issue but this time it's worse because of the blacked out screen.
Any ideas what it could be? Faulty display again?
Thank you

It's over to have this phone for little over 2 years now you should have to change
TIP:
Flash a new stock rom of your phone from sammobile via ODIN.

That would be great, but I'm not a person that buys new phone every 2 years. I was thinking about it though .
When it comes to flashing. Do you think that would help? I don't want to end up with a black screen unable to set the phone up again. Cause overall it's working great .
Hi, i have the same problem, i'm from Belgium, and I have blinking screen problem and wake up screen problem :s
is it a software issue (nougat???)
before the big update (marshmallow i dont have any problem)
i'm on firmware A510FXXS7CRJ6_A510FLUX7CRJ1_A510FXXU7CRJ6_HOME.tar.md5
Turn screen brightness up abit to stop the blinking of screen. It's an issue of the screen hardware itself at low brightness after wear and tear. As for the hanging issue, maybe it has to do with your AOD app? Try uninstalling the AOD app OR flashing a stock Rom OR custom rom OR factory reset and use your phone at a higher brightness that the screen does not blink and see whether it still persists.

Thanks, because of my past experience with the same problem earlier this year I know about that "solution". Unfortunately, it makes the battery die faster as expected. Which is sad because I used it mainly on low brightness. So it's really not a solution at all.
I got rid of the AOD app because I found out that the phone lights up on 2nd try. AOD didn't work at all. I have to wake it up, put it to sleep and wake it up again which is always successful and the screen lights up. The screen flashes white about 3 times in a row now otherwise it works.
I haven't flashed it yet although I wanted to. But I will see what can I do. Thank you though!
I'm having the exact same issue using LineageOS.
It's already been 2 years, but since this thread is one of the first results on Google, I'll gladly add a solution.
Exact same problem for me, went through two screen repairs under warranty, and it would always come back a year later. No difference between Samsung OS and LineageOS, though I haven't tried rooting it.
Found on Ifixit: this issue is related to the AMOLED screen technology used by Samsung (among others). You can look it up, apparently there is a bad (?) voltage management in low brightness which worsen with time.
I could fix it with the "OLED Saver" application on Play Store. It works around this voltage management and allows you to reduce the brightness without the green flickering.
I still got white flashes after the installation, but not anymore the day after. I could even disable this application without the issue coming back.
I don't know what kind of magic cleanup this app performed, but it really is a (screen) life saver.
