Not all screens are the same!

Just have noticed that new units have much better screen in them! Look at the pictures. New screen doesn't change color while viewing under different angles and it dimms instead of turning off! Looks like screen on new Artemis units! Red is red on new units, doesn't have this pink hue.

Seems that HTC has replaced the buggy screens on new devices
Can you post the first 3 digits of the Serial Number from both devices in the pictures?

631 - left
636 - right

now I'm pissed

There is no way for me to tell by just the picture but I think I have the better screen.
I have serial 628 so you would think that it would have the bad screen, then again I am basing it off a picture.
On the other hand, maybe HTC was using the good screens then got a better deal on these other ones, and now is switching back? Because I have not had the alignment issues everyone else speaks of (THANK GOD, I feel for you guys I really do. You see the flip out touch screen in my car acts up and it drives me INSANE!)
So chalk up another inconclusive and basically useless post for me!
Later, Lew

I have a 628 and from the picture I would have to say I am with you lew. My reds look red and I also have not had the alignment issue. My keyboard just sucks!

come to think of it my red looks red too and I haven't had the screen alignment problem.... yet
dude are you using a screen protector on any of those tytn's or both ? same type ?
mine is 628 too

Mines a 632... have screen alignment probs but have disappeared for almost a month. But if their giving out better screens il get it sent for repair

I have a 628 too.
And my red looks red (just like the one on the right).
Never had the aligment issue. I've bought mine as soon as it got in stores.

Nick
What do you mean your keyboard sucks?
I have not had any issues with it yet (knocks on wood, REALLY)
but I think you got yours first. What problems do you have?

When closed the left side of my TyTN is very loose, that is a US quarter. Also it the keyboard is really loose when locking into place either closed or open.

I've got the same issue too!

I have a 635, and my screen looks exactly the same as the 636 and dims aswell.
Cept for the I have issues with several keys not working properly. If you press it in a specific angle, the button doesn't respond.
This is mainly on my 'A' button...

[App idea] Aetherphone - a musical theremin on your phone.

"Turn your phone into a robust musical instrument."
I am an artist and can do UI if a developer wants to tackle this. A theremin can be described here:
Here is a demo screenshot I made:

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
in this demo picture it is showing the "R" reverb filter being scrubbed to 54% the text on screen quickly fades away once the affected button is released.
How to play:
The screen will be able to operate with the vertical axis as pitch (in herz) and the horizontal axis as volume (as %). Optionally these axis can be switched by the user in "settings". Also you can have a split screen mode for two independent instruments OR spit screen with pitch in one window and volume in another is so desired. If the latter sound will only come out when both fingers contact the phone.
Pitch range is by default 100 - 3000 hz but this can bet set to a different bracket in the settings dialog. on the top of the screen it will read the current pitch and closest note your finger is at example: 297 Hz (D)
Waveshape Selection Circle:
Toggles sine, triangle and square waveforms.
Filters:
You have three filter slots that you can customize with 15 different effects. Swap out filters in the settings mode.
• Tap a slot to toggle it on and off while in play.
• Touch and drag side to side on a slot to change the intensity of the effect. While you scrub a large number shows up in the middle of your screen to show you what its value is.
Loop:
Tap loop once and it inverts. While it is inverted it is recording.
Tap a second time and the loop is stored and a number comes up at the top of the screen 1-9.
Tap the numbers to toggle on and off loops. to clear a number drag the number to the settings gear at the bottom of the page. Loop auto snaps to the closest logical length of measure (guided by bpm and time sig settings)
BPM & time signatures can be set by scrubbing left and right. The text pulses gently to the beat and the time sig pulses to the appropriate scale.
Particle effects change under your finger depending on how long you have held a ante and how quickly your finger moves:
Tap a note/vol and a ripple happens like a drop of water.
Sustain a note and you will get many concentric rings fading from that spot.
Zip from one note to another and a line will appear to tell you were you came from. it will fade in one a couple measures.

Read the post.
Whilst this looks way above my coding abilities, I'd love to see this app completed. Good job with the UI, it looks great!

lol, I guess at least proves that there would be an interest in tackling such an app.
Meltus, I am guessing that its the filters that would be the real hard part? I have a hard time imagining the sine pitch to x vol to y would be super hard right? perhaps the visuals might be tricky too, I dont know.

hey man , great job. i think you have found a good developer. i know a man who is exploring music apps, their apps are much simpler than yours. LOL .To be exact, they are music downloader.

this is great! it appears to be a pretty straight forward app. tying tone and pitch to x and y axis inputs on the touch screen. id love to help do the underlying coding but the ui would be tough for me to code. never been much of a ui coder. just logic... perhaps create a github repository for the stub of this app and let us give it a shot.

ok, so I am new, what is a github?

GitHub is something like a SVN(Subversion repository).
It allows multiple people to work and collaborate on the same code.

Galaxy Note Screen Test

Samsung Screen Test
1) Set this image as your lock screen
2) Press power button two times to enter lock screen
3) Touch your screen (without unlocking)

And what does this accomplish ?

Wow.... Strange

Got some wierd lines, probably because of stretching an 364x580 picture to 800x1280
Not really noticable in screenshot, but I guess AMOLED makes those lines really noticable because they are not completely black compared to background ...

same problem ;/

I noticed this issue the first day i got it, looks like a way that it drops to 16bit or less rendering at times to increase speed. If you set the same image a you're wallpaper then it will go from ok to showing lines in blacks at random times. My guess it drops to lower rate with the cpu speed lower speeds os lower bitrates.
You also see this in the gallery flicking through images will show lower rate but once you stop on one it will get better.
This shows its a trick Samsung does to increase ui speeds, id rather have an option to turn this off and would prefer properly rendered graphics at all times even if it causes a little lower frame rate.

You are a lucky one.

Guys... Come on... Calm down. This issue again?
This is not a screen/hardware issue. As "martcerv" rightly said, this is a trick Samsung uses to increase performance/reduce battery consumption. I think Samsung discovered that using a lower bit rate on the lock screen, they could probably increase performance while reducing battery consumption.
Since the lock screen can be pulled up even accidentally inside a pocket, it should not use too much power & instead, be optimized for battery consumption. So, samsung reduced the bitrate on the lockscreen. This is why you may see banding on the lock screen with certain wallpapers. If the same image is perfect in the gallary or browser, then obviously its not a hardware issue... Relax.

is it possible to increase bit rate? cause i dont care about battery, i prefer good looking

i think i know what legion wants to show us...
i'm elaborating on screen issues at the moment, had about 10 devices for now and only 2 (!!) of them had a perfect screen which got down to 2 in gamma test without mods from supercurio and using "standard" mode. all other notes i had only went down to 4! one of the good ones "died" yesterday, since i changed my back cover one of the two units is almost as bad as the other ones were. yellow tint (was not there before!!!) although i changed NOTHING in the system config. also, after the screen got worse, voodoo louder also wants to re-initialize. as if the change of the cover damaged something...
i do not want to speculate at this time, but if this is no coincidence...
will get two other devices today and report back!

When i go on the lockscreen i see only 3 or 4 weird lines at the top of my screen. What i wonder is why the black is mot really black (display pixel light completely off) except the lines seem to be real black.
But after i touch the lockscreen but without unlocking it,.sometimes i get many more weird lines or sometimes even some of the lines go away again.
I think since this lines sometimes are there and sometimes not it should hardly be any hardware issue

What I do see though is pixel bleeding from the text, is that normal ?

Screen colour banding

When displaying gradients the screen has this weird colour banding effect. It doesn't show up in screenshots so it must be the screen?
Does anyone else's Settings look like this? Go into Settings -> Display to see it since the bottom half of the screen is empty. It's on full brightness too and you can see it even at half brightness.

Mine has been like that since day one. With all these issues this will definitely be my last Asus product.

This isn't with the tablet, it's with Android. It comes up in screenshots too.
Here's a photo from the battery usage thread:

I can confirm that the banding is not hardware related. It is with stock Jelly Bean. Currently rooted and running custom rom and do not have banding. I did notice it with stock Jelly Bean.

I have the same thing, it is software related

Lol....
This was even in ics but just larger isn't it?
Just that a lot of custom roms changed it to a flat color.
if you had true "banding" you would know it. I don't think you would only see it on backgrounds of things.
Am I correct in thinking that?

Just go here to check and see if you have "banding" and for example of what it is.

It must be a display issue if you compare how it looks in a screenshot to the photo. Does nobody else see how glaringly different they are? The photo shows it with a pink block, grey block, pink block with small bands that have their own gradients inside that all are light at the top and dark at the bottom.
Without looking at the Settings source, I assume that the background is a smooth gradient going from grey to black vertically. It must just be a low quality screen.

Ok I found the answer. See here: http://www.displaymate.com/news.html The Google Nexus 7 Display Stumbles and Falls Short...
So, what's the problem? The Intensity Scale (often called the Gray Scale) is way off. The display's Brightness fails to increase sufficiently for bright image content, causing bright image detail to be compressed and lost.
Click to expand...
Click to collapse
Also the banding is because they didn't use a dithered image but the low quality screen calibration makes it look so much worse at brighter areas.

NO! It's a ****TY background image. Period. Good grief.

also, it's a 16-bit display. The background should have been dithered, but it wasn't. You'll see these same effects in just about every modern TV or LCD monitor as most are only capable of 16-bit color.
FWIW, this screen is "light-years" ahead of most of the Moto screens available on their phones. With their qHD and color enhancement techologies, they fall short to replicate accurate colors. Still, I don't ***** about it. I like the devices, they serve their purpose. I'm not going to be editing photos on them, so why should I care?

cant find an answer to this problem anywhere so here goes:
History: i have the nexus 7 and ordered early on end july (so an early batch), i received the device with a little bit of screen lift on the left side but nothing else. its the stock rom with no alterations or accidents.
Problem:
the screen lift got progressively worse but the screen hasnt lifted more after hitting about one milimeter withen the first couple of weeks. then the speaker started crackling slightly and a was getting a purple tinge in a game agent dash about a week ago. now as of yesterday suddenly the screen has grey/purple-ish vertical banding and i cant see anything on the screen - but if i take a screen shot the png file shows everything as fine.
dont know what to do, tried the soft reset (volume + / - and power) but cant get into the menus to try and factory reset. is this a hardware problem or a software problem?
what my google asus nexus 7 looks like now: (not letting me post a link to img)
only lead i have is this which is what mine looks like now:

[Q]Screen looks terrible![Q]

Hi there guys,
Currently using a i9505 in the UK, I think thats the right model, it's the Snapdragon model anyway. I recently installed the stability update that fixes that lines smudging in the settings menu, however I am experiencing a slightly stranger issue. Now I cannot tell you if the issue was here before or after the update, I have only had the phone for 2 days and when I got it home it had the update read to install.
Basically, if I open the messaging application the background appears to be "dirty". I know this sounds weird, and it's honestly the hardest thing to describe. Towards the outside of the handset it almost looks like there is backlight leak the the left and right, in the centre there are just lines running up and down, there is an obvious almost texture inside the display almost.
It is only visible in the pitch black, but also if I then click a thread and go into the messaging thread it isn't visible no more. Just to make it clear, on black black this does not appear, it's only on the backgrounds that are like one less than black if that makes sense -_- Is this going to be a future issue, or is it nothing?

Hi. this is a global issue. basically on the areas that is black, LEDs are off, and when you scroll the screen and bring some other colors on the areas that are black the LED take some time to show the correct color and at first, colors appears as purple. this is the smearing issue that Samsung has fixed. but Samsung has fixed it by making the LEDs not to turn off on the black areas by adding some white in black areas, and it only works in Samsung apps, like the messaging and setting. but for some reason all LEDs don't become brighter in the same amount and the screen looks unevenly grey and black. but only in samsung apps. if you look at a completely black part of screen in a third-party app you'd see that its perfectly black. unless you use screen adjuster app to fix smearing in other apps too. if so in every black display, the dirtiness would show up.
and by the way, its a problem with phone's screen, so if you look at the same thing on another display nothing will be seen. just like the screenshot you made, the issue is not visible here.
