Since installing the last OTA update (G930PVPU6BRD2) on my Sprint S7, I have a bad screen flickering issue.
(I read books on my phone at night, using Google Play Book or Al Reader, in complete darkness, with the brightness set to minimum.)
Since updating I can't read anymore because at low brightness levels the screen flickers randomly, like a lightbulb with a frayed wire.
I tried disabling ALL display options, like blue light filter, auto brightness, adaptive display, etc. But nothing makes a difference.
Also, every time I reboot it tells me, again, "Android update complete" (or words to that effect.)
Any ideas???
Factory reset is the only idea I have. It's not like we can flash different kernels or anything. If factory reset doesn't work, then take it to sprint.

Sounds like a bad flash of the update. You're going to have to try a reset. Just don't forget to backup first. That sucks.

Hi,
So I literally picked my N7 up an hour ago, came home, got to the home screen. Played around with it and plugged it into my laptop. Suddenly, it looked like the screen turned off. After a bit of poking around, it turns out the screen isn't off, the brightness is just ridiculously low.
Using my Nexus One as a flashlight, I'm able to just about make out the contents of the screen. I've turned auto-brightness off and WiFi, but no cigar, the screen is still barely visible.
Is this defective hardware, or has a software update fixed this for anyone? I was prompted to install an update, but in my excitement, I dismissed it.
Feeling like this right now ->
silly question but have you tried turning the brightness up? not had any problems with the brightness of my screen. even at 10% the thing is quite readable.
I tried that, it didn't make a difference. I think it's a hardware problem since I did a factory reboot (took me 10 mins just to tap the right buttons) and still has the same problem. Ordered a replacement
Did you try checking, saving, and unchecking auto? Mine is set to the "darkest" but it's still very bright
I didn't tbh, it was too difficult to find the checkbox for it. Without my N1 camera flash, it looked like the screen was off, and even with flash, I was basically fumbling around and hoping I would hit the right option.
I tried a factory reboot and that didn't fix it. The first time I booted, it was fine, so I reckon hardware issue. I've ordered a replacement, hopefully this'll last longer than 5 minutes
Anyone else notice screen Flicker when the display is on the lowest brightness setting? I am noticing it on the bottom half of the screen usually when the phone first goes into the dim setting (manually or automatically). After it is in the dimmest setting for a while, it eventually stops. Or, if i manually move the setting off the lowest setting by even the smallest amount it stops. I've been running SACS Rom nearly since I got the phone, but the flicker started about 3 versions ago. I'm thinking it may be a hardware issue.

Anyone else having this problem? I have my phone set to stay on while charging in developer options. However, when the phone isn't touched for a little bit the screen dims and flickers like crazy. As soon as I touch the screen, it comes back to regular brightness and the flicker is gone. Any idea what the problem is and how to resolve it? I leave my phone in a dock all day on my desk and the flickering is driving me insane. I'm on the original GS4, not rooted, latest KitKat installed.
So the issue got progressively worse and I am approaching my warranty date so I contacted Samsung and they had me do a cache partition wipe. So far so good. I see the issue only so faintly and I don't think I wouldn't notice if I wasn't looking for it. I will see if the problem returns and if so, have the phone swapped out. I don't want to be stuck with a potential dud after the warranty expires.
I've never experienced this with a TW stock rom(http://forum.xda-developers.com/showthread.php?t=2650706) with NAE baseband.
Hi all
I just want to share my experiences with my second Sony Z1 Compact, which after 1-2 month started showing problems with the backlight.
The backlight is unstable, meaning that it is "blinking" while I am browsing webpages. It is most noticeable / present just after loading a page or after scrolling... after a while it seems to stabilize.
It happens no matter if the backlight is set to automatic adjustment or set completely manually.
Also the backlight is not able to be as bright as normal. For outdoor usage in sunlight or bright light the phone is useless due to this.
Also, it barely changes the backlight strength/brightness if I adjust the slider. Something is completely wrong. It happens in Kitkat 4.4.4 and 5.1.1 and after factory resets.
I have never rooted it.
See my comparison videos here:

Have anybody else experienced anything similar?
I have returned the phone to service, but they claimed "no errors found" even though I explained how to do just like in the videoes.
Now I've returned it to service again (as they didn't repair anything the first time) with some more details and with these videoes attached. I will be really mad if they try to give it back to me with "no errors found".
I am 99% sure that this is a hardware problem, and that it won't disappear through any software updates or firmware hacks.
When I use "Always on display" on my edge the screen doesn't becomes completely black, remains like LCD screen with backlight on.
Check the pics: first with Samsung AOD and "gray" screen, second with Amoled Display app on play store with perfect amoled black.
How is your screen?
I've got this very same problem. I've tried resetting the AoD app's settings and clearing the device's cache in the recovery but that didn't fix it. I haven't tried factory resetting yet because I don't have the time now to set up my phone from the ground up.
Do you have any fix for this? Have you tried factory resetting?
* Please note that the diagonal lines are an artifact from my camera, and not actually visible on the display.
nope. I don't think that factory reset can solve this problem.
Today my s7 edge received the december security patch with 273 Mb update but the "problem" remains.
Now I'm using the pay app "Always on amoled" and it works perfectly
It might as well be a hardware issue with the AMOLED panel. After NYE, I'd try factory resetting the device first, and if that doesn't fix it, I'll probably send it for warranty repair.
nah, with another app is perfect. It's software related ( with some panels ) I think Samsung use different panel with different voltage or similar cuz my friends s7 edge is completely black and another one is like mine.
Hello, did anyone come up with a solution to this (apart from using the third party app?) I have exact the same issue, and my colleague at work also has an S7 Edge bought from the same shop with no problem. Mine used to be fine, but stopped being black a few months ago; it also happens with the edge screen {see pics} , but not the third party app. I have the unlocked EU Exynos variant. Likewise have tried different versions of the app, even different firmwares and all have the same issue.
I had this on my first S7 edge after 3 months... only fixed by replacing the screen unfortunatley (under warranty)
I have got this problem and i think I am going to use a guaranty, I dont understand how other third party app works, but there are problems with AOD.
Software bug?????
Interestingly, I had this problem with my S7 Edge from the time I purchased it back in August. It occurred with AOD as well as Night Clock...so much so that I didn't use Night Clock due to the faint "glow" right by my head. Nothing fixed it...factory reset, updates, display tweaks, nothing. My fiancee, who got her phone about a month before me, never had this problem. At the time, a warranty replacement was suggested, but I chose not to since it's wasn't a big deal I just lived without the night clock or AOD since I'd never used them before anyway.
Fast forward to January of this year. My device developed the green vertical line along the edge that persisted through reboots. Some others have reported pink or other color similar lines and it's a fairly well known defect. Had the phone replaced under warranty and the new device doesn't suffer from this problem. My fiancee's phone still has not developed this issue.
I'm wondering if the two items...the vertical line issue and the faint glow from the panel, are related and the result of a hardware defect. I'm going out on a limb and saying yes. I would suggest that anyone with this issue take advantage of a warranty replacement since it appears other screen issues might crop up as well.
I have the same issue, i need help. Please
I have same problem always on back lit so I went to Samsung store in leeds.
the assistant said he couldn't see a recognised
Problem or fault so wouldn't do anything about
it .

It is not a problem. It is just demand of the users. In complete darkness, the AOD background becomes slightly gray, just to make sure that it remains visible.
Ofcourse it, too, can be fixed, by mocking Ambiant Sensor's values. I used XPOSED and installed "Sensor Disabler" from play store, and used it as an XPOSED Module, in side menu, selected "Light" and then "Mock sensor values". Make sure you just keep the value just above 0 lux ( 210 lux is optimum ). It is a sensitive slider, so just slightly increase it.
Auto brightness will be at constant level, better turn it off. However, AOD will work like a charm now! (PERFECT BLACK CONTRAST)
I have a Galaxy S10 Plus, about a year old, unrooted, fully updated, and settings have been reset. This is my attempt to reach out for this issue before resorting to a factory reset that may or may not resolve it.
https://photos.app.goo.gl/1nvkXKkVjUjqgro47 is a screenshot of the issue. This is with Dark Mode turned on. Some apps will not turn Dark and display the buttons properly, but they used to. It's been a couple months, and I don't remember any specific change.
I have:
Reinstalled affected apps where I could, some system apps are affected.
Changed Darkmode off and on.
Forced Darkmode.
Reset All Settings.
Nothing's changed the behavior. Has anyone seen something like this, have any idea how to resolve it? I'm prepared to do a full factory reset, but I'd prefer not to go through that hassle if there's an alternative.
Edit: The buttons display normally in Light Mode.
Ha-ha, fun isn't it?
Same thing on some of my apps.
A small price to pay for the darkness... this site got it right though
