[Q] Purple and teal lines on my phone - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

When ever there are graphical updates on my phone, the colors become weird and look like the picture shown below. Even the boot animation looks like that. My camera doesn't work either and no cellular service.

Bad displaying of gradients in pictures

I'm not sure whether this is a problem with Android (doubt it), HTC Sense in general or the HTC Photos app..
But what I'm finding is that pictures with gradients (usually ones computer generated) have their gradients shown very bady and makes the picture look terrible. Instead of doing a smooth colour transition, it sort of does it in chunks..

As you can see here, isntead of fading smoothly from the red to black, it does those ugly layers. I first noticed it when I had this picture set as the lock screen picture because it does it there too. In bright light its almost impossible to tell, but in the dark it tooks terrible.
Sometimes when I look at the full picture in the Photo app it doesn't do the gradient so badly, but when I go to pinch zoom the slightest it instantly changes to look like that. (isnt just a problem with the one picture btw). I thought it might be something to do with the large picture being resized to fit the screen, but I resized the picture on a computer to be smaller than the screens dimensions and it does the same thing.
Another slight issue I picked up is that black areas in a wallpaper picture don't show as 'true black'. When I view the picture with the black background fullscreen in Photos, the black areas are true black (tested at night - true black of AMOLED screen). But when the picture is set as background, there is a noticeable difference between the blackness of the background and the 'true blackness' of the bottom of the notification bar...
Might be hard to see, but to show what I mean:

Does anyone have any explanation for these problems, and even better, fixes?
I've got HTC Legend unrooted
Cheers

[Q] changing the color of the phone, contacts, and messaging screens

I just recently got my Note 3 last week through At&t and I'm highly satisfied. I have a question that I have not found the answer to yet. The phone, contacts, and message screens are predominantly white with black font. I kind of have a hard time with this due to my bad eyes. I can see better with a black background with white font. Is there a way to change these screens to black? I have watched some YouTube videos and see people with black backgrounds And White font in these screens. Help please.

i have a n9005 branded voda phone.
its overall colour re dailer, messages ,contacts is standard a darkish blue /black with white letters.
so it seems it a carrier thing .?( your colour white with black font or did you by accident enable a wrong settings ?)
one thing, have you tried to go.....settings /device/accessibility then scroll down to negative colours (reverse the colour of screen )
if i tick it my dark screen will be reversed to white etc..etc untick and i have darkscreen with white lettering
there is also other very good settings on that page eg..font size ...short cut
see screenshot ..have you tried this ?
good luck .

[Q] Diagonal stripes/pattern on screen

I've noticed some faint diagonal stripes on my LG G2 (LG-D802). They make a pixel like pattern of stripes, only they are diagonal from upper left to lower right and mostly visible on solid clear colors like red, green or blue. The stripes are very thin and the width of the stripes is comparable/or slightly smaller then the pixel width of my old Samsung Galaxy S2 (>200PPI). In other words, it's not something I see all of the time but it gets noticeable when you look closely. And as I said it is mostly visible on solid colors, and not on text and other edges where pixels normally is visible (not that I think this is the actual pixels I see). One of the easiest ways to see it is to search after "red" on google images and open a red image, but it is also visible in most apps or on the homescreen.
Is this something anyone else has experienced/noticed, or is it it my display that is faulty?
I'm not allowed to post an outside link in my message (new user), but here is a picture if anybody want's to see.
It was not easy to capture this on camera, but the stripes are barely visible in the red of the Google+ icon and in the dark blue of the image icon. For size comparison; I use Nova Launcher with icon size 70% and the Minimal UI icon pack.

Could it be a problem with your screen protector? If not i recommend sending it in for a check..
Thanks for the reply.
I don't have any screen protector on, but the lines does seem to be fixed to the screen. I.e. if I move an object the lines does not stick to the object but "new" lines gets visible, so it can look like it can be something with the glass.
If nobody else has experienced the lines I will definitively send the phone in for service.
I tried the local phone store, but the guy only laughed at me because he did'nt see it. Great service attitude when you make the customers feel stupid
Maybe you are talking about the touch sensors?
All the phones have it and it's more visible on xperia phones.
Maybe, but I think the lines/pattern is to small and dense to be the normal grid that people see. When I turn the screen off I can (barely) see the the digitzer grid, but it is a completely different pattern (horizontal and vertical lines) and the lines are separated by several line widths (some millimeters maybe?). The diagonal lines I see are very close together. It looks like they are only a line width apart from each other.
One other thing I just noticed is that the lines does not rotate when the screen is in landscape mode. They still go from the front-camera corner down to the corner to the right of the LG logo.
Is it nobody with a good sight that can confirm if they see the stripes or not? Would have helped me a lot when proceeding with getting the phone in for service.

Can you make the AOD custom picture brighter?

I have a custom image on my Always On Display screen but, despite being a simple black and white image, it is a lot dimmer than the rest of the items like the clock and notification icons. They seem a crisp white while the image is grey which loses some of the thinner lines in the picture.
Is there anyway to alter how it displays custom images?
To be clear, I'm not talking about overall brightness, I understand how that works with auto-dimming. I mean that the picture is greyed out and dim compared to the other, system, elements like time, date, etc.
Thanks

Dispay has shadows, burn in, translucent, opacity or bleedthru.

Greetings all,
I have a S7, and when I have a open white area, lets just go with messages, When I open up the message (text, stock) and compose a new message, I get the white screen however in the background I can see the home screen icon's very faint, with colors. I did a screen shot and when on the phone you can see the icon's, however when I move the screen shot to the PC I dont see any of the icon's, I was hoping to post the pic, but the pic is perfect. I dont know how to explain this, but it weird. I have done two factory wipe's, this is stock, I have not modified this phone. The carrier, (If needed) is T-Mobile. Any and all information will be greatly appreciated.
Ciao~

If you take a screenshot and it does not display the same as what you are seeing it means it is NOT software related unfortunately this is screen burn
thats what I figured, but its very bad, I have never had any of Samsung Phones every do this. If the display is burned, why would the icon's have color? I see only the background icons, when the screen is white. If it was burned should I see it on all the screens?

The screen burn burns in the colors a possible way to test this is change your background icons from what they were previously and see if the colours have changed on the screen where you can see the burn in..
Alternatively Get a screen test app https://play.google.com/store/apps/details?id=ua.dp.ustav.screentest should let you put solid colors on the screen) and set it for all white (there shouldn't be any other color showing) then for all black (there shouldn't be anything but black or a uniform very dark gray). If either one shows any sort of picture "ghost", the screen has burn-in.
Apparently it helps slightly if you set the screen mode to cinema. (Settings>Display>Screen Mode>Cinema)
Hope this helps
