I don't know if screen flicker and screen dimming are the same thing but I encounter a similar issue whenever brightness is below 30 percent.... Other than that my Nexus is flawless besides a rare notification freeze

So, if mine is also called a screen flicker, how do I fix it?
When my N7 screen went all black out, I have to use a torch towards my N7 screen sensor to have the screen bright up again

I just got mine yesterday. Not rooted but I noticed if the screen auto turns off....sometimes it is locked up. Hitting the power button won't do a thing. Have you had this problem?

Yes, i have this problem too. Then when I have no torch beside me for the sensor, i would need to press power button for 10sec+ for a reboot. How suck it is. This is the only thing bugging me on N7

I just got off the phone with Google play. Having a new unit sent to me. Glad to hear (unfortunately) you are having similar issues.

So, no one seems to know how to fix, then it's hardware problem and have to send to ASUS?

hey!
if it is the same issue as i have (screen turns off in auto brightness or manually set the brightness to minimum), i dont think it is an hardware issue.
i think the minimum background light is set wrong in the system.
also i dont think it is hardware related, because many other owner af a n7 are reporting this issue.

So is that means only hope is hope for next firmware fixing it?
Sent from my GT-N7000 using xda premium

i dont know... if so, i hope for a quick fix
but you could try the app
tegra prism toggle
(costs about 1$, needa root)
maybe it helps

testcenter, thanks for the recommanded app, but i not wanna root at this moment.
I guess in the mean time just not using auto brightness and pray for not dim out again

Galaxy s4 purplish tint/blurring

Hi. I got my SGS4 a couple of days back. Initially, didn't have any trouble at all (mostly because I had been using it on max brightness). But now I am facing an issue I had been horrendously tormented by in the past. The grey gradients have a purple tint and the greys blurr on scrolling (esp on black background). No solution or cause of the problem is apparent to me.
I used to have a Nokia C7 back in 2011 and it used to do exactly the same. This is most evident when you have lowered the brightness. The dividers in the settings blurr & turn purplish on scrolling. Watching dark scenes in a video also shows some purple/pink smudges.
Is anyone else having this problem? Or is it just me? Is it present in all the phones or just some or maybe just mine?

Sent from my GT-N7100 using xda premium

I know AMOELDs do have a tint. But the blurring & smudges in videos is totally unacceptable. Is there a solution to this? Like some hue/gamma correction app? Or some color calibration for such screens?
Sent from my GT-I9500 using xda premium

Try some different kerner if there is one for S4 to calibrate colors..

In some angle u will get pink or purple tint and it s not problem
It s normal to have different experience in different angles

Has anyone, as of yet, had any luck with a different kernel?

[Q] Display brightness issue

I'm currently on my second N3 (the first one had vertical lines in photos) and looks like this one has a bad display. When using Tapatalk with the dark theme, the bottom left corner/edge of the display is brighter than the rest. When testing with Screen Adjuster, the difference is very noticeable. The issue can be seen even with just Thumb Keyboard with WP7 theme.
Has anyone else noticed this kind of problem?

Return it and buy from another store. Seems like these guys are selling you lemons.

The two phones are from different stores, I'm still waiting for a replacement for the first one.

Mine upper side screen seems brighter than below screen.. but this condition only happen when i use xda app set to dark theme..i thought the xda app the one that problem..not the phone...

Check it with the stock messaging app, it should have a uniform brightness. Mine is glowing on the left edge and especially on the bottom left corner.

Should this happen again, The vertical lines are solved by clearing cache/data in the camera app

The problem can not be seen in a screenshot. And the camera lines disappeared after a hard reset but came back soon after.

You may notice that the black screen when you open the settings. Not symmetric Colors.
There is a difference in the backlight. Increase in the left of the screen.

AMOLED has no backlight! the issue is due to the production process (basically: the more of the center of the wafer your particular screen has been cut out, the more uniform it will be)!

Change from Adapt Display to Dynamic. Best thing to do to resolve the problem.

Dynamic? Hideous more like, my eyes can't stand any of Sammys over saturated pre presets, Movie is closest to normality I can find personally.

If you want to get rid of display brightness issues, just switch to Dynamic, as the 'blacks' in Settings would be even blacker, to the point where it doesn't really light up as it uses the OLED technique of showing true black.

Touchscreen issue

Hi Guys
I seem to be suffering from a issue where the touchscreen has a dead spot.
Now I had an earlier issue that caused all sorts of issues with screen responses - ultimately ending in no response unless I hit the power button to lock and then unlock.
That problem lasted about a week and then stopped - my thinking is that there was an app update that solved it.
Now however the issue has resurfaced (seemingly after other app updates) but it is a dead spot roughly where the first notification would be on the notification draw. Any ideas as how best to find out the cause of the issue, or a fix?
I've included screen shots showing the touch trace.
Cheers for any help

I can't help you but with some custom rom there can be a bug with it until I make some setting changes to the Nav Bar, but otherwise I don't know.

Forgot to say that this is stock 4.3

Many people are complaining about 4.3... It's causing many problems
Thu'umed from my Predator

What I don't get is why it went away after the first time.
I don't really want to factory reset if I can help it.
Is there a way to look at an update history for all your apps? Then I can pinpoint the offender.
Sent from my Nexus 4 using xda app-developers app

I've found a solution.
After factory reset and safe mode not helping I came across a comment in another thread.
You have to Disable HW Overlays and Force GPU Rendering. Now its not perfect and can have an occasional fit but does seem to solve the issue

Display of black weird

Anybody an idea whether this is a display damage? Black appears not normal.
Sent from my SM-N9005 using xda app-developers app

Black crush
Well,this is called 'black crush' or 'black clipping'. It is still there a little bit,but nothing serious. The first Note was horrible... Don't worry,nothing is wrong with the phone,it is a software issue,and (I think) it will be fixed soon.

Im very confused as it really distorts the display of the black.
In the settings the search field has a deep Black. Rest is more or less grey.
In the toggle menu the bottom bar has weird stripes.
It's not just a small issue. ...

You posted screen shots. No one can tell anything from those you need to take a picture of the problem using a camera. The phone's been out for over a month now. If what's happening to you were wide spread I assure you it would have been brought up (numerous times) by now. If whatever you're seeing was like that out of the box (before you loaded any apps) it's probably a h/w problem with your specific device.

I have the same issue too on my Note 3!
I'm from Singapore here.

I didn't notice that the pictures appear perfectly normal on other displays.
I did some shots with a camera.

That isn't normal - I'd you are running a custom ROM I'd take back to stock to see if the issue persists, and send it back if it does.

Mine too. Isn't that supposed to be the way the display looks? Just kidding.
A display that looks like this isn't normal and if there were a lot of them people would be going nuts.
It's either something s/w related that's fried the graphics drivers or a h/w problem unique to specific phones. If it remains after a hard reset than it's h/w and the phone needs to be exchanged.

Tried the hardware reset but didn't change anything. Bad luck this time.....

That is really something wrong.
It suppose no strip at telco area.
Beside search bar, the rest bottom part is suppose black also not grey.
I believe your screen is defective.

I've factory-rested and it's the same.
Re-installing exactly the same J1 firmware (in Singapore it's the latest) via Odin also yeilds same result.
Another friend of mine is facing the same issue.
However, the ambience at the Samsung stores are so bright, and it's hard for the customer service officers to see

Well I'll see what Samsung After service Germany will say... the point is that the screen looks ok if you test the blue, green, red and black screen test under *#0*#. But during normal use I'm faced with the problems as shown above
I'll keep you updated.
