Image rendering issue - Nexus One General

I just downloaded a map from Sugarbush Ski mountain in Vermont so I'd have it handy when skiing there. Unfortunately, when I zoom in the image is so blurry that I can't really read the text. The same map looks fine on my desktop computer.
Unfortunately I can't post a link to the map because the XDA developer's site won't allow me to (you can't post links until you've made 5 other posts to the forum). Just google 'Sugarbush' and you will be able to find the static trail map image. Someone else who's been around here longer could post the link in a follow up message.
I've tried viewing it in multiple programs (standard browser, Dolphin browser, gallery view), and all show the same problem.
Can other Nexus one owners confirm that they have the same issue?
Any suggestions?

I think android might downsize/downconvert images automatically so you will not be getting the original resolution of the image.
UPDATE:I can confirm that the image is definitely lower resolution than the one that appears on desktop. Here is the link:

I just mounted my Nexus via USB and checked the file that I'd downloaded to it. The actual file stored on the Nexus One is full resolution and displays fine on the PC. It's just on the Nexus that it fails to display well.
This seems more like a bug then a feature.

I just made a simple 2000x1000 graphic with two strings of text, one aliased and the other antialiased with a crosshatched background.

You can clearly see how blurry both lines of text and the crosshatches are when you zoom in on the android browser or in the gallery. It looks like there is either a huge amount of compression being applied to the image, or that the image is being resized for viewing and the blur effect is due to a loss of detail that you don't get back when you zoom in.
I don't know if imageshack has a bandwidth limit, but here is the same image on imgur.com. You can see the extra effects of blurring, though you also see a lot of jpeg artifacting from the high compression imgur apparently automatically applies.

Low resolution images with Opera

A colleague of another website pointed this, which went unnoticed until I paid attention. The problem is simple, fire Opera, load any website and see the images rendered in half resolution. All the images look pixelated when you double tap to zoom in; if you zoom in further it gets worser.
Anyone else?
Opera Mini 4.2 doesn’t have this problem, the built in Opera Mobile does.
Most likely your network proxy compressing them on the fly to save their bandwidth. I'm fairly sure orange do it.
Nope, I'm on WiFi connected to a network without any kind of proxy.

Also im noticing similar for example in Rss Hub, pictures just look disgusting, comprared to NetNewsWire in iphone for example. Opera is not this ugly, but I noticed that too when i got this phone. I thought its just my imagination...
I have the same problem also in PIE., but in opera it's even worst.
I have just tried with my Diamond, and same thing. So it must be Opera that has designed the browser to present lower resolution images in order to preserve memory or speed up browsing. Nevertheless, it's a pity that you don't have the real thing on such a high resolution screen.
Opera Mini 4.2 does use full resolution images, but more compressed. It looks much better.
and there's nothing in opera:config
Yes, I've looked at opera.ini but there's nothing related. The registry doesn't have any setting either .
Nice to find you also here igalan (nos leemos...).
Doesn't look so bad for me.
Make a try with google images in full resolution and zoom in. No pixelation at all until you zoom too much
Hi man!
Ok, I've found the reason of all this. When you double tap on Opera, the zoom level that is being applied is larger than 100% which means that pictures are stretched and results in some pixelation. Manually reducing the zoom level until you get the page rendered in 1:1 resolution (not zoomed out or zoomed in) gets you full quality images as well.
i connected my laptop up to mt hd via wifi to use it's HSDPA connection. browsing in firefox images are rendered in half resolution. when i hover over an image a message appears saying press shift+r to improve the quality of this image. when i do that it downloads the image again in full resolution.
the fact that i'm using firefox on my laptop and just using the internet connection on my phone makes me think that my network provider is the problem.
what do you think?

images don't show full resolution

so whenever i want to view an image at full res I can't I always had this suspicion when viewing stuff on the net and zooming in it just didnt look anywhere near a nice as on my pc (or windows mobile phone)
I just sent myself an email with an image (png) high res (2xxx by xxxx) the image is a map with lots of small images and text on it, when viewed on pc you can read all text just fine but on the phone its looks terrible (at least with default image viewer and the image viewers I have downloaded)
Whats going on?
I remember reading somewhere before that the phone can only display/render upto a certain amount of pixels regardless of how large your image is.. Also I notice on the default gallery viewer when you swipe around fast the image is ultra pixelated and have to wait for about 1-2 seconds.
This is really annoying. I don't think there is a fix at least that I can find. What a shame our powerful phones can't do what older phones can. Is it an android fault you think?
Sent from my GT-I9000 using XDA App
quite a shame endeed...
also when pinching into pics inside the gallery app, it won't load the full pix map
So I have been looking for a fix, b&b gallery does render the full image which is nice but not sure about browser. Do any of the browsers for android render full images or are all the same?

[Q] Wallpaper - ugly banding in gradients

I've been searching, and have seen lots of threads about similar problems with the Evo and it's fairly low-color screen, but I was under the impression that the Droid X has a 24bit color screen so this shouldn't be an issue.
Anyway, I've got some wallpapers (cropped and resized for the Droix X from the originals at Ultralinx)
They look fantastic on the computer. They're the right dimensions. Tried saving as JPG and 24 bit PNG, but the outcome is the same. When I copy them to the phone and set them as wallpaper, the gradients don't look smooth; there is color banding all over the place.
I've got screenshots and originals up on the web, but can't link to them until my account is approved by a mod.
EDIT: Added attachments instead, but the forum super-compressing the images doesn't help their clarity at all.
Hey,
i've got the same problem.
That's not funny at all, I really don't know how to save it, that it looks like on my desktop pc!

Sorry to be off topic but I cant help but stare at your notification bar. What theme is it?
It's my own notificationbar.
Have to search the files first
It doesn't seem to be the screen. I dropped those images into my dropbox, and opened them in whatever viewer dropbox opened by default. The image was smooth as I zoomed in, until I zoomed in far enough to see a moire pattern. I also opened it in Astra's built in viewer; again there was no banding. However, when I set the image to be my wallpaper, I see the same banding you are seeing.
Bad news is, I don't know what the problem is; good news is it doesn't seem to be a screen limitation.
Thanks so far!
But what's the problem than?
I really have no idea :/
Ah ha! Google turned up this app: "Wallpaper Set and Save" (Sorry, can't post a link because I'm new, apparently. I attached an image of the QR code instead.)
It says it hasn't been updated for 2.x, but it worked fine on my droid x (running the stock rom with launcher pro.) Using it to set the exact same wallpaper, I now see no banding (although I did in the preview screen.) It's worth a try, although I'd still like to know what is causing this issue (since it obviously isn't a hardware issue.)
I attached a screen capture so you can see for yourself.
Edit: The forum's image compression adds some artifacts; it looks even smoother on my screen capture. Even here it's a big improvement over the others though!
Its probably the gallery app that is re-compressing the wallpaper and creating the bands

images in browser/apps displaying in low res

Hi
just got a galaxy s on tmobile in the UK.
It's good but it seems that lots of images in the browser and displaying in low res, they all look blocky.
It's happening in apps too - the thumbs of peoples faces in facebook are blurred/blocky, images from the engadget app are blocky etc.
I've compared to another galaxy S and the images on that look fine.
Would anyone have any idea whats causing it? thanks
Edit - It seems to be intermittent too. For example, if i do a google image search, the thumbs are sharp, but if I click on a pic and it goes into the slideshow view all the images are REALLY blocky. If I click the link to the original page were the image is coming from the image loads up fine.
It seems to be my carrier, tmobile.
When i put other sim cards in the phone it works fine.
Very annoying, makes buying a nice phone like this for web browsing kind of pointless.
Anyone know of a way to bypass this?

Photos uploaded to Facebook are DOWNSIZED - please help?

I can't believe I am the only one having this problem, as I am now onto my second S4, and this new one also has the same problem, and my friend's S4, on a different Network, also does exactly the same...
The issue is, if I shoot a photo on my new Galaxy S4 in full 13Mp resolution, this produces an actual image on my device, that is 4128 x 3096 in resolution, with a File size of around 4.7MB As soon as I share it to Facebook however, either by clicking the Android Share link on the image and choosing "Facebook" as the destination, OR by using the Facebook App direct then choosing an image to upload, then I end up with a problem...
The image that actually arrives on Facebook, is heavily compressed with noise, and is resized down to just 1032 x 774 resolution, and a tiny file size of 178 KB (instead of the 4.7 MB masterpiece it actually was).
It does this with EVERY image I shoot - 100% of the time. And worse, is I mix things up a little, if I first REDUCE the resolution of my camera BEFORE taking a shot, if I drop it down to 8MP and take a photo, then despite the image now being a SMALLER photo, the image that arrives at Facebook is then BIGGER than those shot at 13MP, arriving at 1632 x 1224 instead.
Go figure...
But I suspect it's a bug in Facebook. However, given that my guess is that it affects 100% of S4 users, 100% of the time, I can't believe there are not thousands of discussions and debates about this issue... I can't find ANY discussion, for an issue that is there for ALL users, ALL of the time...
Please note also - whilst I am aware that there were high quality image upload issues on the S4 with Instagram too, this has been fixed in part, through an Instagram update. In my case, the photos that are resized down when uploaded to Facebook, are nevertheless perfectly correct and of the true size and quality when uploaded to any other Android Share location, or Social Networking Site, such as Google+ etc. It is only when sent to Facebook that the images are instead massively compressed, degraded, and down-sized.
So can anyone tell me - is this a known issue, for which the cause has been identified..? Or were none of you aware of this yourselves? If so, can you test it, as it's repeatable 100% here, on various S4's on various networks...
Take a photo on the phone in FULL RESOLUTION. Uploaded it to Facebook using the android sharing function on the S4. Then go to Facebook on a desktop PC and locate the photo you just added. Choose the option to download it to your PC, and save it. Examine the downloaded image, and identify if it is a true 13Mp image, or if for you too, the image has been uploaded at just 1032 x 774
And if that is the case, I'm amazed much more has not been made of this issue. I got the S4 because it has such an amazing camera, and I love uploading photos. Alas, as it stands, the device is useless, as it uploads my images to Facebook at a resolution and quality, lower than that of my first ever 1.2MP standalone Digital Camera of 1998...
Comments or ideas anyone?

I asked the same question in this thread: http://forum.xda-developers.com/showthread.php?t=2256054
Haven't really gotten an answer yet. For now, i use an image resizer app, resize it to the dimensions of 3789 x 2131 .. and then upload to facebook... that ensures the maximum size gets uploaded to facebook. There doesnt seem to be a workaround for this until facebook updates the way its app uploads photos.
I noticed the exact same thing when going from an HTC One S to the S4 and I posted on another thread asking the same question. It's driving me crazy. Pretty sure it's the FB app and not the S4.
I was searching for a different matter regarding the fact that the Facebook app forces you to upload the pictures using a square shape instead of the original photo shape. I recently switched from iOS to Android and found myself with this annoying feature. iOS-version of FB app allows you to upload pictures without having to crop them into a square. Weird. --> Don't ask me how, but this is fixed now. No more square-shaped pictures.
Then again, I tried to by-pass this issue by uploading the picture through the mobile-version of the site/web app and found myself with this pop-up from Chrome.
"Unable to complete previous operation due low memory". Found this thread ( http://forum.xda-developers.com/showthread.php?t=2101893 ) but the solution given is not exactly what I'm looking for. I wish to know why is this message popping up and what am I supposed to do.
Going back to the subject... I experienced the same thing when I uploaded a picture to my timeline (no cropping issue there). Resize is done in a way that messes up the whole picture with the compression.
I'm assuming they've built an algorithm that resizes the pictures to prevent people from uploading +4MB files, data usage... I don't know.
Is there any solution to any of my issues? thank you!
If it matters --> Samsung Galaxy S4 (GT-I9505) - No SD card.
Also my problem with my octa s4.
I wonder why my friend's samsung duos mobile uploads are fullsized, while my s4's uploads are pixelated and so low quality.
For now I'm using Nokia 808 Pureview for my mobile upload but android do have vast application choices for editing photos before upload so I'm really annoyed by this.
Sorry to resurrect this but I'm having the same problem and couldn't find a fix

Maybe it's just Facebook doing the automatic downsizing.

You're not having this problem?
If I use the mobile browser to upload, or a 3rd party app, it uploads in high resolution.

I don't know, my pictures seem fine when using the Facebook app.
Oh man I never noticed this till today!
I'm using a Note 3 and it downsides the pictures to 1000*xxx... what? That's like a 4x downsize... why???
Is there any fix (except uploading pix from the PC?)
its 2015 and the problem still exists! i think i'm movin to g+
