Backlight going down/up...

I don't even know if my eyes are cheating me, or the tablet is indeed have a problem.
(If you followed my previous topic, this is the second tablet I got, brand new.)
Noticed the issue in Hangouts first, with AI keyboard and dynamic screen mode.
Disabling dynamic seemed to fix the issue.
But yesterday I saw it again... at least I think.
It was only a Chrome window, and I was reading news.
The screen went from lighter to darker while I did nothing with the tablet.
Anyone else seeing/having the same issue?
It's so damn annoying.
I mean, I never had such issue on my displays on any device. That's why I think it's not my eyes...

Try turning off "Reading Mode": [Settings] -> [Device] -> [Display] -> [Reading Mode = Off]
Just a thought.
This may be a silly question, but, is your brightness set to auto?

Yeah, did that yesterday night as a last resort. Didn't notice the issue happening since then, but I will keep an eye on it.
By the way, now I have a working tablet, I'm quite satisfied. (Except this.)
Thanks for the tip!

I believe it happens whenever an image is shown. So you will probs notice it when text takes up the entire screen and as you scroll down the page and an image comes into view the screen will change brightness.
Just have to get used it a guess. I kinda am lol.

the tablet has dynamic backlighting that i haven't seen anywhere to turn off (it's not the screen mode, i have that set to movie). there was a thread about it earlier and i think only the OP and i were able to see it. it's a lot subtler than other devices but when you have a dark scene the screen dims a bit, then when you have a "bright" scene the screen increases the backlight a bit.

I have this issue and its especially noticeable with gifs on screen.

Thanks fellas!
Back to Samsung it goes!
Well, at the moment I contacted the local consumer rights service and will try to use the law against the carrier.
Which basically means that they will have to refund me for both the tablet and mobile data fees.
Yeah, this provider got the best prices. And the worst customer service.
And yeah I waited YEARS for this tablet to arrive (I missed the original 10.1 bandwagon)... and it's riddled with bugs. Don't even know what to do if they do refund.
Should I buy an iPad? But that's dumb as a rock. A normal tablet? What's the point in that?
So yeah. Wait for the Note Pro? But who knows if it won't have the same... or even more issues?
Yeah, #firstworldproblems, I know.
But I had a Latitude XT2 laptop with a pen. Most magical thing ever.
I just wanted to write again. ;_;
pls sammy why u do dis to us...
@madsquabbles: Nah. I disabled dynamic, set it to normal or what. Auto backlight is off ... I checked everything.
This is not a feature, but some stupid power management or firmware issue. Not that Sammy would address either. (See the lack of 4.4 or multi-seat support. The tablet is far from brand new.)
ps.: I don't think it's that two of you could see it. You two had the same panel issue as I do. (Remember, Apple also loves to mess up things like this. Like their latest problem with the Retina MBPs had the burn in problem. It was the same machine, but two companies were shipping the LCD panels. One was faulty, other one was perfect. I suspect the same.)
@Geordie Affy: I found this issue happening on news sites. But now it happened on a wall of text (it was a news site again, but without any images.) And today, even in LectureNotes. Not that it's bad, BUT it's annoying as hell.
Baaah. Sorry guys for "mentioning", I just tend to use this stupid mail symbol to refer to people.
Silly internet. There are no symbols left that would cause no harm. ;_;

Use the law against carrier? Good luck.
If everything else works, as you said, then why don't you fix this issue (not sure if it's a bug, as you call it).
Turn the auto brightness off, control it yourself.
Or install lux, if you're rooted, and you have much better control.

This is different. It's not auto, it's not scene mode, it's not what you think it is.
Uhm... okay how can I explain this.
If you don't have it, you can't guess what we mean.
It's like... you are reading some text, and it goes darker, then brigher, then darker. At the very same screen, even if you stop scrolling.
Then if you got images, it can become worse.
It's terrible because you spend like 10 seconds each time to check if you eyes are bad or there is something fishy going on.
As I said it's possible a faulty panel provider or something.
Now I'm on the carrier-war. If I lose that, I'll send the tablet back to Sammy for LCD replacement/repairs.

I have seen this exact issue and have been able to reproduce it on my friends unit as well. Open up snote.. Start recording a voice memo and watch.. The screen flashes dim and bright. Dim and bright.. It drove me nuts.. Then I noticed.. It was actually doing it in unison with the red blinking dot of the voice memo. So I think it's something where there is an animated gif/pic on screen. I will test turning off reading mode to see if that fixes it and report back. I think I also have mine set to dynamic

[Q] Is the screen on my phone going to die?

this started a few weeks ago and it dose not bother me too much, but im worried that it will stop working.
It only happens at the lowest brightness and when turning off the screen.
i have a video you guys can check out.
https://www.youtube.com/watch?v=9UFTQDmr-aI&feature=youtu.be
let me know what you think

Try this:
Settings > Developer Options (Click more then 7 times on "Build number" in "About phone" to open these options) > Check the option "Disable hardware overlays".
After doing this, try to set lowest brightness.
I hope it will help you.

Could possibly be a hardware issue. Did it come into any physical contact?
Sent from my Nexus 4 using XDA Free mobile app

i haven't dropped it recently so im not sure about physical damage.
my only thought is that i often you blue wallpapers and as far as to my knowledge blue sub-pixels ware out the fastest on AMOLED displays.
but other than that ive got nothing, really hoping it dose not break as i can afford to repair it

I want to blame the problem on the rom, since only on low brightness did the glitch happens, have you tried backing up your phone and flashing another rom temporarily?

Incoming Verizon Update

I'm on T-Mobile but I just got home and phoned up my co-worker who has the Verizon version. Says he noticed a slight improvement in overall touchscreen responsiveness. Biggest problem that he said was fixed was ghost touches (touching one portion of the screen caused a menu to pop up somewhere else for example) being completely gone. Idk, it's really starting to feel like a lot of these bugs should have gotten squashed in the product testing phase. Wonder if this is the same update as the mandatory one T-Mobile got way back. I wouldn't think so since the T-Mobile update did not fix touch screen issues for anyone.

Anybody notice the auto brightness isn't as dim anymore which is a good thing IMO.

well that sucks because the lowest wasn't low enough for me.

2. I do NOT see a difference in QC 2.0. I was about 8.94-9.0 volts draw on QC 2.0 before, and now I am at same. I call it as no change in QC 2.0 speed - so still not "true" QC 2.0.
Click to expand...
Click to collapse
Forgive me if I've misunderstood QC 2.0. But my understanding is it can charge at 9V or 12V. So just because it's still at 9V doesn't definitely mean that the phone isn't receiving more power, the amps could have also increased.
To provide 15W, for instance, you'd need 3A at 5V, 1.67A at 9V, and 1.33A at 12V.
It's possible to still get 9V from the charger, but draw more amps, for faster charging. Using something like Battery Monitor Widget, to monitor the current provided to the battery, would be a useful tool.

Try the paid version of Lux ... Can get the screen REAL dim!
G4'ed it!

After reading all of these posts, I'm really hoping for a similar update on T-Mobile coming soon. I'm glad this isn't just a placebo and an actual solution to a software problem that doesn't require getting my phone serviced.

SIdeloading apps problem???
UPDATE: Nevermind - issue not related to Verizon update... Had Twilight app kick on after sunset and that overlay app (reducing blue light) is what caused the touch issue. (Credit: brainwash1)
Enabled installing from "Unknown Sources" and installed an app yesterday no problem
I just did the Verizon system update and reboot, now on sideloading install I get the permissions list with CANCEL & INSTALL buttons at the bottom. Looks normal, but the INSTALL button doesn't respond to any tapping. Tried landscape mode also, just to move where the button was located on the screen, but no dice. CANCEL button works fine.
[Also, if there are many permissions, so I need to scroll, the INSTALL button starts as a NEXT button, then changes to INSTALL when done scrolling to bottom. Doesn't matter, neither NEXT not INSTALL buttons function]
Not sure what else would cause this. It seems like the Verizon system update broke something. Anyone else having new problem sideloading after the update???

Whats your carrier? I think the other guy is verizon. So am i, and i put no thanks

Do you have an app running that overlays something on the screen? I've had this in the past with a couple of different apps. Try turning off anything that's running.

Twilight app kicked on after sunset, which is why I started having the problem. Paused it, and no more issue. Thanks!

If you or anyone else don't want to be bothered by the OTA in fear of patching a exploit for root block LGDMSClient.apk with the debloater tool by @gatesjunior. If anyone downloaded it and do not want to install it just clear the cache from recovery mode. That should remove it from the phone.
EDIT: To enter recovery mode power down the phone and then hold the volume down and power buttons when powering back on.

Wiping the cache did nothing. It keeps popping up saying it is already downloaded and ready to install.

OK, then the update isn't stored in the cache partition as other phones. It's a bit drastic but a factory data reset will do it. I ended up taking the update and then froze the updater. It did improve the touch response so I have no need for further updates. It updates the kernel because that is where the necessary changes are.

my touch response "seems" improved but I still get ghost touches..
I love pretty much every aspect of the phone, but the issues I have with the touchscreen are maddening at times, if I didn't see widespread reports of issues I would have Verizon replace the phone, but I am not sure it's worth the hassle..

It might be worth replacing. I first had a black one that had the problem pretty bad. I returned the phone and went back to my S6 for a while but ended up picking up a blue one from Best Buy and this one works great. The touch wasn't that sensitive before the update but now it works really good. My battery is really good on the blue model too. Keep in mind I paid full retail for mine so when I returned the first one there was no restocking fee. I go to BestBuy just for that reason.

I was having some touch issues just as many are experiencing. Just today I installed the Google keyboard from the play store. I enabled the new keyboard and stopped using the LG keyboard. I have been using it this way for about an hour and I am much happier. I am hopeful this will take care of my issue. This is on a Verizon G4.

I took the update yesterday and threw my Verizon G4 on a Qi Wireless Charger last night and the bug where it has crashed in the AM is still there. Not sure about that.
Basically every time I wake up on a night of Qi Charging, the phone is crashed and freaks out.

Update:
My phone is now getting hot and doing the screen brightness bounce like it did out of the box. Going from 100 to 90 to 80 to 90 to 80 to 100 to 90.

I switched from the LG keyboard to the google keyboard day one so that was never a source of my issues.. Just today.. twice post update I have had ghost touches launch the app switcher icon while texting and caused me to switch apps on accident.. Doh.. It's frustrating to say the least.

Never had a problem with wireless charging besides it's slow.
No screen brightness fluctuations.
No ghosting on screen.
Sounds like there's an awful big batch of bad phones.

There are definitely bad ones. I returned mine again a few hours ago because my outdoor pictures would come out either dark or overexposed real bad. I tried manual mode and auto and no matter what I did they were awful. So I'm back to my S6 again, it was fun while it lasted.

Blurry Icons and Quick Settings/Notifications when swiping

Hi, so I got my Moto G4 about 2 days ago and I noticed today when I was swiping on my home screen from left to right the app Icons release a blurry trail like some sort Motion Blur , and In the Notifications too the Wi-Fi and Cellular toggle leave a blurry trail of the icon when swiping up or down. Is this a software problem? I just Factory reseted my phone and the problem is gone but reapeared later again. I think that it's because I had too many app icons on my home screen (I had only 2 pages)?

Posted there still no solutions thought. I noticed when my phone gets hot the blur is almost gone (It wasn't noticable) What is going on? Also I flashed a older version of the firmware and still had that blur. It got heavy again after I installed like 12 apps and then I updated again to the latest build and still the blur is there.

Try to go to service center.Make sure you have locked the bootloader.

I also have this problem. The support advised me to send the phone to a service center.
For information, this usually occurs when the screen is hot, about 10 minutes of use. Particularly visible when used as GPS (waze or google maps).
This is a hardware problem. Not software, it remains after a quick restart.

Thanks I'll lock the bootloader and go in to the service center and let them check it out. Altrought in EU it doesn't matter if it's unlocked I think but I'll lock it again.

Thanks for the info! For me it's the opposite when my phone is cold (To be exact, the battery when it's at 22,0°C in CPU-Z) the blur is there and really noticable. When I use my phone and the battery hits 35-37°C the blur is almost gone everywhere but an app named "Discord" that has really small text has the blur and it's really noticable. I'll send it and see what they can do.

Two fire tablets showing different brigtness

Hi guys,
I have to fire 7 in tablets both bought at the same time from same place. Both are running the same Lineage-12.1 ROM (12.1-20170802-Unofficial-ford)
But for some reason when i keep them side by side one of them has a very dull screen brightness where as the other is nice and visible. I am not sure if this has to do with the hardware or some missing setting in the one that is dull. I tried making both 100% bright from the upper menu but the screen difference is still the same.
The bottom image is the brighter one. Any idea if some setting somewhere is causing this?

On checking further I noticed that the tablet which is showing dull color seems to show the exact same even when I adjust the brightness slider in the top menu. When the slider is on 0 or 100% its the same. that tells me that the software slider is somehow broken?

Known kernel issue with custom ROMs. Symptoms typically rectified with a reboot. If no joy try a full power down with a 5 sec pause before restarting.

Sorry for the late response Davey126, for some reason it didn't post my reply when I used my cell phone the other day. I tried to restart a few times but still have the same screen issue the brightness controls dont respond. Will upgrading to the latest release help with this issue? Is there any other fix to permanently fix the problem?
Thanks for your help.

Probably not. Likely have to sideload a full version of FireOS to refresh/replace the kernel - then start over. There is no known 'fix' for the problem other than keeping memory load to a minimum (or using the swap tweaks that I outlined elsewhere).
