Hi everyone,
I'm a former N1 owner and just bought a new NS i9020a from Negri Electronics and I'm finding a few funky things that I'd like to run by you guys. I'm suspecting that the phone might be defective, especially 1 and 2 below. Anyone else have these issues, or perhaps they are really non-issues?
1) My screen has pretty bad horizontal banding. It's most obvious in the notification pulldown, but is also noticeable with certain wallpapers, dead pixel test apps, etc. Please see screenshots below. Has anyone else had this, and do they fade away over time?
2) The galaxy live wallpaper has a layer of static "stars" or something above the actual spiraling galaxy. This layer kinda looks like stars, but some are splotchy/smeary. The galaxy itself also has a pink border/box around it too. I've factory reset twice and the same thing happens. Maybe my wallpaper is defective? See screenshots.
3) The screen in general has pretty yellow whites, especially in low brightness settings. I am not wowed as I thought I would have been with the SAMOLED screen.
4) When in the camera app, the picture doesnt actually take up the entire window. There are a few columns/rows of black pixels surrounding the picture. It's not centered either. See screenshot.
5) my volume rocker has a middle click, so there's up, middle, and down.

i'm on an ns4g, and i have the exact same problems. its not big enough to bug me though. btw, the samoled is more known for their deep blacks than their whites.
I would get that exchanged asap but since you bought it from Negri you will hard time.
i have a i9023 and got exactly same black line in camera app, it just doesn't take up the entire windowi believe it's a "feature"
i think "middle" button in volume rocker is normal, cause every android device i owned it was present, sometimes when you press it, your system gets lagged for a while, like 5 secs, i believe it's something related to debug setting, also you can use it to disable power button in cw recovery (don't know why)
the rest of your problem i can't actually help, since my screen is not the same!
edit: when you change from photo to video in camera app, don't these lines/rows change at all?!
Camera looks normal, just like mine.
Banding looks bad though. Possibly defective display. If you have warranty, you should exchange.

Hello,
I've just got my replacement phone (the previous one had mechanical problems) and the display seems a bit strange with this new device.
There are visible banding effects in color gradients, (web pages, pictures) I know the Lcd has only 65K colors, but I don't remember those bands being so strong on my previous device.
Could you fellow G1 owners check this on your device please? I am in Hungary, Europe and I don't know any other G1 owners here (you know it's not available here, actually mine is an ADP1).
It's easy to check, the effect is very visible on http://www.google.com/news (Google international news mobile site) in the Android browser. It's slightly visible in the dark blue title bar, more in the light blue bar below and very strongly in the "Sections" bar far below.
Please check it and tell me what you have found...
Thanks,
Peter
I see the same issues with google/news. I think it has to do with google's site and/or the g1's browser. Here's a few high quality jpeg gradients Black-White, RainBow and Blue-Red. Unfortunately google compresses them and they look like junk online. So, here's a .zip of the three gradients your can download right to your phone and view with Astro, or extract to pc etc. They should look fairly smooth on the g1, better on pc tho..
use there gradients for w/e you choose.
Hello sonikamd,
Thanks for your help! Interestingly your test pictures look better (smoother) in the standard picture viewer app than in Astro's viewer. Can you confirm that?
Also how old is your device? It looks like that mine (the replacement device) is very old, it's serial number is lower than what I have sent back (purchased in december).
Thanks,
Peter
Just one last quick question: on the incoming call screen there are strange lines appear, do anyone see those on the G1 or it is just me?

No, I am not crazy - I am a graphics artist and really sensitive to things like that.
Thanks,

nope... [filling characters]
Hi lilithpro,
Thanks for the image, however you won't see the effect on a screencapture (like you attached). I made the pic in Photoshop (from a captured emulator screen) to show the effect - I exaggerated the effect in the pic a little.
You should check your device's lcd during an incoming call to see it. I think it is something to do with the lcd panel. Today I managed to check an other G1 and it showed that effect, too.
So it seems it is not my ADP1's problem.
So I just got my Vibrant yesterday and today I notice something wrong with my screen. On a white background I see a dark Streak. I just wondering do you guys see what I am see?

I do see it, pretty weird... have you tried to play with the brightness to see if it gets worse?
If it was me, i would call to get a replacement... you got it yesterday so you're in the 14 days period to do return it, they will send you a new one.

Thanks for response. I have tried playing with the brightness but it is still there. Anyway looks like I have no choice but replace this device.
Yeah, even if you could "fix it" in some way, i think replacement/return it's your best choice. Good luck!
There is an free app called "xlight" (IIRC) in the market. It will fill the screen with white, red, blue, green, or yellow light. My phone display appears very uniform when using it, you might want to try it (or something like it), just to confirm the problem.
Looks like a defect to me. My vibrants never had anything like that. My first nexus s had a screen problem. It had a ring shaped watermark when viewed with any solid background. Yours is a streak but looks like a similar effect on the screen. You should get it replaced if reseting, etc doesn't fix it.

Make sure your replacement can get into download mode and recovery using the hardware buttons. Try it in the store. If not, keep asking for a new one. (Samsung has acknowledged this as a defect so tmo has to replace it)
If you don't know how:
For recover while the phone is off, press and hold volume up, volume down, and power at the same time.
Let go of power as soon as you see the first Samsung screen. You should be at the recovery screen.
For download mode pull the battery and plug in the usb cable. Hold volume up and down and put the battery in. You should see q little android digging.
If I screwed those up someone please correct me.

I have major display problems on any CM based ROM with crazy jumping and unreadable screens.
I have tracked the problem to the display of white lines. A screen shot is OK, so its hardware - either the Adreno200 GPU or my screen.
Problem Description:
Lines (pixel lines that is) containing a significant amount of white randomly do not display. As a result the display "scrunches up" with a gap from the bottom. Any background to the app, and sometimes the desktop will display in the gap at the bottom as it has not been written over.
Note the "bottom" in this context is the button end of the phone, thus rotating the phone leads to different screen areas being affected.
Affects all the CM ROMS I have tried, with the latest CM10.x ones being the worst. There was no issue with the stock LG ROM.

Coloured triangles produced by "OpenGL Demos" app are OK
2.
White Triangles loose lines and scrunge up. I used the Demo prog as the code is the same, just a color change!
3.
Screen shot, so not a software issue. What they should look like!
5.
Google Play. Unusable. Note hte white background is OK. It just seems to be items that are layered onto the screen.
Apps with black backgrounds and grey/coloured text are fine.
What have I tried?
I have tried messing with OpenGL HW settings with no effect.
I have messed with screen brightness.
I have tried various ROMS.
I tried moving processing from the GPU to the CPU, but that completely messed the display, and I had to re-install the ROM
I haven't tried altering the refresh rate from 60hz, but cannot find if this is possible. I think its a refresh problem, but not sure. Its almost as if the white lines are sent faster than the screen can handle and they are missed during the display phase.
The other theory is that the GPU does some special acceleration cleverness for white areas the screen can't handle.
Any ideas?
Any Adreno200 settings I could try?
Any bridges nearby I could jump off?
p.s. Photos taken from the Optimus Nexus Me port here:
http://forum.xda-developers.com/show....php?t=2397696 not that it matters which ROM it is.
Obviously, it's not "soft" problem, it's a "hard" one, replace the screen.

That was kind of where I was heading, but I was concerned that an aftermarket screen would have the same problem. This screen was fine with the stock ROM, so was hoping for a magic setting change.
Thanks for the response. Really wanted to run your Zoe ROM, but that was worse.
To be honest, I wouldn't replace the screen on this phone anymore. It isn't worth it anymore.

So my galaxy s5 has been working great for the past month or so that I've owned it. I have rooted it and done some adjustments with the xposed installer, but I haven't flashed any custom roms yet or anything. So then today out of nowhere, this little stripe appears on my screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So that's annoying. I took a screenshot on my phone and then moved it to see if it was the actual screen or just the picture being displayed on it. However, the screenshot shows no black stripe when zoomed and moved around so that the would be screenshotted black stripe wouldn't be on top of the actual black stripe. Then I restarted my phone, still there. I booted into recovery mode to see if it still happened when not opening the actual normal use, it was still there. Then finally I tried pulling out the battery and putting it back in, still there. I'm a little frustrated and a bit scared that I've already voided my warranty by rooting it and disabling knox. Also, the line turns sort of white when against a dark background and goes away when the screen is off. It's not the worst obstruction in the world, but the phone is less than a month old, so obviously I want it to be perfect. Any help that can be offered is appreciated.
I'm on verizon if that makes any difference.
Edit: I haven't dropped it, exposed it to heat or magnets or anything of the sort
It's unfortunate that you didn't post a full size, full resolution image. We can't make out any fine detail in your reduced resolution image. It would also have been good to know if the band is invariant in size as you make screen adjustments or display primary colours on screen. Or if it shows up in downloaded photos?
We are of course seeking a pattern or otherwise trying to narrow down the potential causes. Since we don't have much to go on yet, we can only guess, it looks to be a hardware defect. But there isn't enough information to be certain.
It would still be useful to look for a pattern in whether the band varies at all with different colours and brightnesses on screen. You can also use the dialer code *#08# and display red only, blue only, white only, black only, etc screens to get a better sense of which pixels are apparently contributing to the band.
Also try backing up the phone (to save your user files or installed apps), then revert to 100% stock firmware temporarily, followed by a factory data reset. If the problem persists it is all but certain to be a hardware issue. Claim it under warranty then if you can.

Green glow, only shows on black or dark screens. Tested with a burn check app for this picture. I toggled all screen options on and off in various configurations, including all the adpative stuff and Soli. No changes. When I press the screen, a normal press anywhere, the glow will change slightly. I'm approved for an RMA, but I'm wondering if anyone else can see this before I do that.
I used night sight for the picture, so the green glow is more pronounced than with the naked eye.
Have not noticed this on mine.
Where did your purchase it from? Hopefully the exchange is smooth!

Purchased from Google. Already approved for an RMA, just don't want to do that if it's widespread, or if it's not a real issue (is not consistently glowing, sometimes it's there, sometimes not).

Yeah send it back.
The one and only place I've seen anything remotely close is the YouTube music app. Screenshot brightened to enhance glow....
That's intended, though. To show you when the radar is looking for gestures.

Right, at first I thought that's what my glow was, Soli being active. It's in the same exact location, which would make suspicious it has something to do with the Soli light. Thanks for the help all

Just disable motion sense, launch spotify or youtube music and check if the glow still shows on top of the screen. If not, then it's for sure the indication of soli radar checking for movement. However it should not be green...
