[Q] Anyone suffering Screen Flickering?

Twice in the last couple of weeks I have had the screen flicker when I turn it on, turning it off then back on again has sorted it out both times.
I am hoping it is either down to some CM autobrightness thing, or under/overclocking...or both.
Unless anyone thinks this is the start of my screen dying?
Any input would be great

what do you mean by flicker? a slight flicker of the backlight? and by slight, i mean realllyyy slight

Nah its a full on flicker as in you can't use the phone like it.

I know when the forums started some people, like 2, were saying when they set their brightness setting to the lowest setting it would flicker. I suppose they returned it.

my brothers phone is doing that right now

I've had mine flicker about 5 times in the last four days. The screen semi locks and jumps up and down a little in a juddery way. When i try to scroll it works hap hazardly. Turning the screen off and on sorts it out. Not sure why it does this but it only started at the start of this week.

Had this happen to me on a reboot today right as the cm logo was fixing to come up. It was only for a split second, like scribbled green flicker. It was after I updated to 6.1.1

Mine does it all the time when the screen auto dims.
That was right out of the box stock.

ok good to know I am not the only one, I will keep an eye on it but I do think it might be to do with autobrightness

Got a screen protector on? Maybe the thickness/quality of screen protector could be an factor?

Do the options in Cyanogen Settings,.. UI,.. Auto Backlight,.. Filter thing not sort anything for you?

I had the same thing happen and I just returned it from walmart and got a new one.

I can confirm that some phones do have a screen issue where the backlight flickers at certain brightnesses. Mine does it when at lower ones. Stock rom, etc, doesn't matter.
I also have battery issues (45 mins with screen on at 20% brightness will kill the battery).
I am having mine replaced today.

Replaced my phone, no more flicker, and it seems like the battery lasts twice as long now. Very happy so far

[Q] Anyone else noticed strange colors?

Just have been noticing some off colors that look washed out sometimes on EG22. I haven't noticed this before, however, about two weeks ago I had to get a new phone when mine met concrete, so it could be this screen's issue, or EG22. Not sure.

If youre running a theme, I heard that some of the images could come out brighter but thats a concern for the themers so my guess would be when the phone had its date with the concrete

Sometimes this may happen due to the kernel itself, when we get source, im sure someone will put in a voodoo color mod into the kernels to make the colors more natural.

Its not about natural looking colors. Every once in awhile I will hit the power button the lock scfeen will come up and you can tell the display just looks a little off. If you hit the power button again, turn it off, then turn it back on again often times it has fixed itself. Sometimes you have to do it 3 or 4.. It could just be the new phone i got then. Have to keep an eye out and take it in if it starts acting up. I was just wondering if it is just me, or if others have seen the same thing.

I did see this on my phone before my touchscreen crapped out. I hope you aren't in the same boat since your phone is new.

screen brightness issue/overheating

i've had my phone since launch and ever since my screen brightness gets automatically reduced due to overheating.
At first, the screen will dim itself ever so slightly. After a few seconds later, it returns to normal brightness and it repeats itself.
Eventually, i notice upper half of my phone as well as the screen itselft getting really hot and the brightness dims permanently.
I usually keep my brightness setting at the highest level but when i go into the menu to increase the brightness setting back to highest, it tells me the brightness is reduced due to overheating. only way to increase the brightness back to highest is to turn off the screen and let it cool down for a few min.
whenever this happens im usually browsing the internet for no longer than 10 min before this kicks in. i seriously dont think im using too much cpu by browsing forums for this super phone to be overheating.
i've read other post regarding auto brightness feature causing issues but i have not enable this feature on my phone. and its kinda hard to believe that i have to lower my brightness to prevent it from overheating.
anyone having this issue? man i'd hate to return this phone and start from scratch. tia

I would love to hear more about this...My experience matches yours perfectly. Does everyone's phone do this? If enough people say no I'm going to get a new one...it is absurd. I got those phone almost primarily for it's beautiful screen which I can't see at full brightness for more than a minute or two!?? fnck that.

Is it possible for us to get a brand new replacement unit even if your 15 day return period is over? Assuming that other users are not experiencing the same problem.

Mine does this as well, I think it's some kind of fail safe if your phone is running hot cranking up the brightness is just going to add more heat so they limit it while it's running hot. Once it cools down then it will allow it again

I have this same issue, I have to recharge above 30 percent to get the point where I can max the brightness up again

Hmmmm... guess im not the only one with this issue and hoping that it is addressed in the future update. However, it seems odd that no one brought this up? Could it be that there are only a few of us that are affected? If so, im beginning to think that this is a hardware defect?

Ive had the phone since day one. I am not having this problem. The only time it ever gets noticeably warm is when using the phone for extended periods while charging. And this is not hot like some people are reporting. I would try exchanging the phone.

Mine did this the other day, I normally have auto brightness on but I was showing a photo so i went to turn it off and crank the brightness up but it didn't let me. I pulled the battery for 10 seconds and it let me do it.

I think alot people are not experiencing this issue because they either keep the auto brightness feature turned on or keep the brightness setting at a low level. I dont wanna exchange my phone if im gonna have the same issue. What can i do?

You may be on to something.... I rarely ever have my screen at 100%, mostly because its just too bright for me.
Although, I did watch 2 hours of video (1 hour from the SD card, one streaming from Netflix) at full brightness, and never had a heat issue. A little warm, maybe, but certainly not hot.

[Q] Getting horizontal lines intermittently

My phone is about 4 weeks old now. Last week I noticed that sometimes, powering the screen on shows some light pink/grey horizontal lines. This is in standard portrait mode.
They are more obvious in medium to bright light and eventually go away after another screen off/on.
I'm using the standard HTC ROM (Sense 5.0, Android 4.2.2).
Would this be a hardware issue?
Thanks!

Sounds like hardware. I knew someone with a Thunderbolt with a similar issue. Next time you see it, don't turn your screen off, but lighly push on the screen in different areas and see if it makes it better (or worse). This may have happened (if its hardware related) due to too much pressure being put on the screen accidentally, perhaps while in your pocket or something.

I did notice the lines again and tried pressing on the screen but nothing changed from what I could tell.
I ended up contacting HTC support and was recommended a 'Dead Pixel' app. Except they didn't specify which one. There's tons on the market and some claim to fix dead pixels. Not sure how true that is or that I even have that problem. Anyone know if those apps work?
Also, they recommended doing a factory reset. Not sure how that would help but I'm willing to give it a shot if there's no other ideas.

I'm not familiar with the apps either, a factory reset would help rule out a software related issue, and is probably the first thing that Verizon would do.

[Q] Purple smudging on screen

Hey guys, I'm thinking this is simply a common drawback from having an amoled screen, but I just wanted to be sure. While using auto brightness in a dark room (e.g., during bedtime) the brightness level on my device is properly turned down, but I've noticed that when looking at applications that use a black background there will be a lagging "purple smudge" when scrolling or sliding through an application. I first noticed this while using the Yahoo Fantasy Football app in bed. Again, I read that this may be a common problem with phones that have amoled screens but I just wanted to make sure I'm not the only one with some sort of defect. Are you guys experiencing this?

I have used several amoled screen phones and have never had an issue like that. I now have a note 4 as well and I'm not experiencing anything like that. I tried to recreate your condition as best I could and I'm not seeing it..... good luck with that one!

yeah, it always happens on amoled. s4, s5, and the galaxy tab s has it. it's just how it's always been

Nothing to be worried about. All I have had have done this and the note 4 is no different. Just remember, it's the BEST display available on a phone right now... or so I have read

mine is so terrible, its making me crazy! specially when watching a movie, its all purple, it started the day after i bought it and now got terrible ! my movies get all purple :|(not that much but really annoying)

I'm having the same problem on my note 4 (SM-N910C) after the lollipop update... It's making me very angry! At least on my device the effects seem to be rather substantial... I'm sure this wasn't happening on kitkat...
Anyone else having this problem?

So I tried to reproduce this and under no circumstances does my phone exhibit this under auto brightness.
Though no matter how dark it is my phone will only drop brightness to about ~15-20%.
Even if I drop the brightness down to 2-5% manually it does not exhibit the purple lag.
For my device... only at the absolute minimum brightness does it exhibit this behavior.
If your device is exhibiting this kind of behavior what brightness level is it actually at?
