black lines across screen - Transformer TF300T Q&A, Help & Troubleshooting

Hey guys, I bought my tf300t about a month ago & I noticed something that I hadn't really noticed with my cell phone. Every time I load solid colors, there are very faint darker colored lines going up the screen. They look kind of like when you record a home video & you record the TV. They look somewhat like this, though not as intense. http://www.youtube.com/watch?v=2sv7LkNE5II . They look more like waves rather than dark lines. I think its only on certain colors because it wont happen with red, or yellow. I noticed it when I was on the tumblr app & even on the google voice dark themed app. Is the screen supposed to be like that or is something wrong with the hardware? Thanks.

I just RMA'd my tablet only to find out it's banding because of a low quality image. Your tablet is fine :victory:

Thanks so much for answering. My questions never get answered. It seems like it only happens with the navy blue colors, so thanks for clearing that up!

[Q] for those that use the xda app

When you start the app, at the xda splach screen is the bronze / red colour the same across the whole screen or is it like a gradient getting lighter towards the top left?
Just wondering if my screen is duff but maybe I'll be better downloading a screen test app.

No, nothing wrong with your screen for that reason. Just loaded xda and it does change shades from top to bottom.
If you think there's issue with the screen, google search for a photographic color calibration image, that should give you a good image to check with.
Thanks. I thought that was the case as I haven't seen this problem in any other apps or when using the phone normally. Still a relief to hear though!
no clue, i have set mine to DARK theme to safe power.
but when i look at a BLANK WHITE page, the 2 bottom corners just above the 4 soft buttons have a weird purplish gradient, which did not exist in Galaxy S
but that is due the Concave screen design
Mines on dark also but I'm talking about the splash screen that shows on starting the app - whether light or dark theme selected.
No such purple tint here.
The xda splash screen gradient looks a little banded because of the pentile sub pixel layout of the amoled screen. Nothing really wrong with your screen, that's just the way it is with these screens. It's a trade off.
Don't think I'm seeing banding, it's just the fact the xda splash screen tends to lighten as it gets to the top left of the screen.
From what others have said this seems normal though so. I'm not concerned.
Ah got it, I mis read. Yeah I think that's normal.
This is slightly off topic but relevant to the xda app. When I first view a new thread using the app, it always jumps either to the last page or a random page. Or if the thread is only one page long, it starts halfway down the thread. Again this is for new threads I've never viewed before. Anyone else experiencing this or know how I can fix this?
Thanks!

Yep seeing this too and never quite worked out the pattern / reason.
Don't worry about hijacking the thread, my question was answered long ago

on the Nexus S
i have a very nice and smooth dark brown to light brown gradient going from bottom right to top left
on the Galaxy S
the same gradient looks like chopped, chunky, banded, it's like looking at a picture in 16bit color (SGS) vs 32bit color (SNS)

That's interesting. I thought these used the same screen technology - samoled?

That's originally what I meant with my post cause I see the banding on my screen too. It should be identical since these screens are literally identical I believe.
that's what i would like to know as well.. i was left when i did the comparison

[solved] Xoom screen question

I just ditched my Notion ink Adam for the mighty Xoom. I'm glad to say I'm impressed. Now for the reason behind my post. Is it normal to see a diamond like pattern(what I suspect to be the digitizer) behind the glass.... I first noticed it while playing with the youtube app. The deep black colors gave way to what I thought was just noise from the video, but after looking at it on an angle with the screen off you can definitely see the pattern.
Is this normal? Last I remember seeing a digitizer was on my Mogul.
Sent from my PC36100 using XDA Premium App
A small moire type pattern or a large contrast difference pattern. I have seen the large pattern occasionally. It doesn't seem to interfere with actual usage.
it the screen capacitive touch sensors (dunno the technical term). i can see it on just about every touch screen except the ipad - go figure.
the 101 is a crosshatch, the nook color are dots, this xoom is a crosshatch with some kind of checker pattern.
I figured it was normal, just didn't expect it to be so profound. It has no hindering effect on user experience. I hope people don't take this and blow it out of proportion as a flaw...lol

They probably will.. lol I've seen people make issues of of something trivial like a button squeaking when you press it.. I can already picture people saying "my xoom screen is messed up"
Sent from my HTC Glacier using XDA App
yeah the only time you notice it will be on dark scenes/backgrounds with ambient light and holding it at a certain angle. the 101 is more predominant but it's really not a bother.
Bad LCD panel?
Hi everyone. I just bought my wifi-only model from Staples today (Sunday). I noticed a little "problem" with the LCD panel when I turned it on, but disregarded it.
While watching a movie, I noticed the issue in full force. When a movie file is playing and there is a black background, I can see "mini-panels" and it's very distracting. I don't see this on a solid black background without media playing so I'm guessing it's something with the backlight. I'm attaching a photo (glad I was able to capture it this way!).
Anyone else seeing this? I didn't look close enough at the store's display.
And so it begins...

that's the capacitive sensors. i wonder how apple hides theirs.
Ive got them too, didnt notice it on any other devices ive used but its just the capacitor mesh that moto decided to use. My glass almost seems wavy as well (like not 100% flat) so not sure what my feelings are on that yet...
my guess on the waves is that it helps curb reflections.
Yeah what you guys are seeing is definitely the digitizer. On most touch screen devices you can see the digitizer at the right angle and with bright enough light (ie sunlight seems to bring it out the most). My guess is if you test this is a lower light setting you wont see any of the digitizer.
I have also noticed the digitizer on the xoom screen relatively easily.
well, ive just noticed the waves. i usually see small waves on screens but these are warps. good thing i'm trying to pay attention to the image on screen instead of the reflection, lol.
I have seen little warps on the bottom of the screen like 1/3 or the way to the middle and 2/3 to the right side (like a couple inches off center on each side). They are also in the same relative position on the top. My guess is this is how the screen is attached? It would be great if someone could take a good look at theirs, it may take looking at the reflection of light in those spots to actually see the warp, but I would really like to know if it is just mine or it is on all of them. And BTW I see the digitizer too, but it is worse on my HTC inspire 4g.

Circle on my screen?

There's a transparent circle on my screen and you can see it wherever you are on the phone but I can't send or I guess post a photo cause I believe its s hardware issue, nfc chip maybe? I think it's in a circle. Is anyone else having this problem? What should I do about it?

Where is it located?
Someone said that it is caused by the vacuum cup that is used to handle the display glass (during the manufacturing process)

Are you sure it's not a 3red party app called circle launcher?

That may be closer to an answer.
Op, can you take a photo of your screen or make a video of it?

I've always had this weird circle problem on my screen but didn't think much of it. It's mostly only noticeable with a solid color, like dark gray. Since I've been running ICS, there's a lot more gray in use, especially on the Contact screen and it's getting to be a little annoying.
Here is a picture of my phone and the image I created for the test. View this image on your phone and see if the circle shows up.
Maybe a relative is trying to contact you from beyond?
I like californiarailroader answer, but It is probably due to a suction cup like was stated before. Co-worker puts one on my protected screen at work and it leaves a similar mark. I would just buff it off

I noticed this last night while using Reddit is Fun on dark mode... Kind of annoying but not the end of the world. I also hate that the screen doesn't get as dark as LCD screens do (aka iPhone). I hate being blinded by the lowest setting when I want to check a few quick things while in bed. The grey out apps are too annoying to be worth it.
That's why I wish the settings menus were white and apps were all developed using a lighter color (or the choice of a lighter color.)

Lock Sreen Font Colour Keeps Changing

Hi there,
I recently upgraded to an LG Velvet 5G running Android 10. For the most part, it's been great, but when I set a custom image as the background of the lock screen, the clock font keeps changing from white with no outline to black with a white outline. At first I thought it was just the pictures I was using but it doesn't seem to make any difference; if the text is on a light background it still sometimes appears white and vice versa. I also wondered if it had something to do with the automatic night mode setting because it seems to change around twice a day, but disabling that doesn't make any difference. Is there any way to disable this feature? Google searches and digging through the menu haven't helped so far. I'd be happy with it always remaining one or the other or being able to choose which it is, if that's an option.
Thanks!

Hi, benpeltz.
I'm on a Velvet SD845 not a 5g. But I've noticed it a couple of times.
I had a G8X before it and it happened a lot more so I think it's some kind of LG bug.
Peace,

LOL, no problem.
Oh, may I ask you something regarding your Velvet?
Either I'm going crazy too or experiencing a screen issue.
It seems mine has kind of a greyish screen....I know it has a pretty bright screen, but It seems like the blacks aren't really black.
And when I pull down my notifications bar while having something like a movie, or a YT video or even my Settings, the notification bar gets really stained in grey (with the black around) where there's something written in white. Idk if you can understand what I'm trying to say, it sounds confusing and I'm not a native English speaker lol.
But I can try to record it and post it for you.
Anyway, you're welcome and thank you in advance!

Have you tried changing it to "Vivid" screen color? Settings->Display->Screen Color. Personally I felt like all the colors were a little washed out before I did that.

I actually did. But it's not just the colors that seem washed out...it's this thing that when I have a black image with bright letters or a white image surrounded by black it makes a grey stain around the white. I'll post s screen record so you can see it. Man, it's killing me not knowing if I'm crazy or it's something normal, although it's pretty ugly and annoying for me. LoL
There you have it. Hope you can understand me better. It not only when pulling the notification bar, but also during videos or even when using a simple black wallpaper with a bright detail in it.

Are you referring to the "frosted glass" effect, where you see the background faintly behind the drop-down menu? If so, I certainly get it with the drop down but I don't get it when I'm playing videos. I'd appreciate a screenshot of that to make sure I'm tracking with you though.

You're not crazy at all. Lol
As i mentioned before, I think this is due to some bug.
