[Q] Low display quality - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hi guys,
I have my Xperia Z1 Compact. The smartphone is advertised(and reviewed!) as having very good display quality. However I cannot agree with that. My previous phone was Iphone 4s(so 2-3 years older smartphone) and while I really loved android as a system(it has its drawbacks though) I can't say that I loved sony's display.The quality is low. I can't even call it average. Much worse than Iphone 4s' display. There are four main problems that I noticed:
1) Unrealistic colours - the most annoying problem. Tanned skin look orange or red so any photos from beach will look like basket with tomatos. Just check the picture on polish wikipedia of politician 'Janusz Palikot' and see the difference.
2) Any details completely missed in a shadow. Just watch the beggining of the video on youtube called "7. bronn the commander"
and see difference between Z1compact and 4s(or your computer):
3) viewed images quality in applications like facebook are much lower than in real(or on Iphone). When I view a picture in facebook it seem to be less sharp than if I download the picture on computer, send it to e-mail and then download it from my e-mail to smartphone,
4) When i check gamma in app called "display tester" (option: gamma detection) the result is 1.4 while i read that it should have been 2.2. What's the reason?
What's the reason of those drawbacks(the third one is the least annoying but still) and how can I fix it? Is there any way to calibrate it(someone did that?) I use app "screen adjuster" but it's solve problems only partially and it's heals only symptoms not causes.
BTW White balance DOESN'T help.
PS. Sorry that I don't post the exact links but I am not allowed to I am attaching photos anyway

my dispaly is fine. It looks same on all Z1c's. Check the pictures I attached yourself. How is that possible that smartphone advertised as having top quality display works like this and cannot even display human skin properly? Iphone 4s i almost 3 years older but the display is FAR above sony's.
Anyway is there anything I can do to fix it?

Interesting Camera Behavior During Recording

Hi all,
Last evening I was playing with my device at home for its video recording capabilities when it suddenly started to rain outside. So I wanted to shoot some video for test purposes in vga format and to see how it did.
You can find this small clip on: http://rapidshare.com/files/251776461/VIDEO_002.mp4.html This is a 3.5 mb file with 36 sec. footage.
During recording something interesting happened; when I turned the camera from left to right, the device reduced the brightness of the footage to almost dark as if that part was so sunny; which resulted a crappy video. But when I turned the camera to left from right the brightness would come back again. I believe this is a sign of buggy driver.
For your information, Contrast is +4, Saturation is +4 and Sharpness is +3. Effect - none, metering mode - center area, flicker adjustment - auto, capture format - mpeg4.
Please note that I did not put my finger on any sensor on the device during recording.
Just see the video to understand what I mean ) Any ideas?
LOL!!! XDXDXDXDXD
SORRY!!! hahaha
It's called PHYSICS When you point your phone camera to the shiny clouds, it will adjust the colors lool
Imagine yourself looking into the sun. Won't you close your eyes to prevent that too much light enters your eyes ?
It's the same with the camera, it's not a bug. It's just adjusting to the picture. If point the camera into a dark room, you'll see that everything gets brighter and if you point it at light, everything will get darker
btw, is it possible that you're from turkey?
LOL!!! XDXDXDXDXD
SORRY!!! hahaha
It's called WRONG ANSWER. There's no sun in the sky and I point my camera to the houses which cover at least 80% of the view; it is 19.00 o'clock at evening, it's not shiny; but because of buggy software the device reduces all the brightness so you can not see or record anything at the end!
Btw, I am from Ankara, Turkey.
I do think mr PumpAction has a valid point (besides acting a bit like a 10 year old). I also think the camera tends to 'darken up' a bit too much whenever there is a high contrast scenario. In your case: the sky vs the ground. It may not be sunny, but the sky is bright white - thus the camera tries to compensate - and unfortunately overcompensates turning the city into a dark black.
You may want to try to alter the 'measuring mode'. I'm not exactly sure what the translation is in English (or Turkish for that matter) as I have a Dutch model of the tp2.
Anyway: get into the camera application, choose Video mode, then go into the Settings, hit the ícon 'advanced', then get to page 3/4 and select "measure/exposure mode". In my case it's the 3rd option on page 3. I can set it to "average" or "middle area". This may help. Then again, it may not.
Good luck =)
also it wat raining. Bug change there were some reflections. Did you film inside the house? So through the window? That would explain a lot.

IDEEA - Hi-res photos application

Hi guys!
despite i use my HD for 9 months now, i still didn't find an application to make photos stored into my HD to be seen in hi resolution when they are attached to a contact or displayed by TFD3D within Photos and Videos tab
it's kinda of frustrating when you take nice pics with a dedicated camera with +5Mpx and then transfer them into HD
i know that there are some "manual" methods to make them displayed in hi-res but this is very dificult when you have more then 10 pics
so i am asking if you, smart guys here, can make such an application in order to be used by all of us with less programming skills
i am sorry if this app allready exists and i dind't find it out. if so, please point me to the right direction
thank you and best regards to all of you!
this is interesting - 105 users view this and no comment
if it is intersting, why no comment?
if it is not interesting, why +100 views?
It's interesting and I would like such an app as well - but it doesn't make much sense for me to comment because I have no idea on how to program it!
And I'm quite sure most of the 105 other users that have read this don't know either!
Tap on the low res "framed" image on the Photos and Videos tab to open the image in glorious high quality.
Slide left and right to scroll through the images in the album.
As for contacts, add the high quality image to the contact on the phone, not via Outlook, and it will show a high quality version on the phone.
Hope this helps and I haven't totally missed what you really wanted

nope
i know what you said and this is not how i wanted
i want to copy hi-res pictures from my cam into my SD card and them to use them to attach to contacts or to display on "Pictures and Videos" tab without any manual trick in order to be displayed in hi-res
if this is not possible "by default" because of some windows or htc bug, then i want an application that can be run and then all pics to be displayed in hi-res, no matter what i do with them
would that be possible?
It should be possibly, its just that no one has ever developed such a program and I can't see anyone doing this either
sorry, dont get that.
every picture, i transfer to my touch hd from an external source, are displayed in high resolution.
you sure, you dont need some glasses?
please add a screenshot to show what your problem is.
Hm, do you want a 1:1 pixel mapping? Then you will have to scroll around on your display to see the image.
Attention modern art:
Attached picture shows the relation of a 5Mpix image (2kx2.5k) to a wvga (480x800 black rectangle) screen.
Typically images will be downsampled to show 'all' information on a smaller resolution. Simple example: Having a 16x16 image and you want to show it on 8x8 screen you could take the average of 2x2 pixel blocks of the image which will give the pixel color in the 8x8 screen. This will introduce some bluriness.

smart line! did you came out with it all by yourself?
the low res pictures problem of HD when attached to contacts or displayed on pictures & videos tab is well known.
maybe i missed something and it is solved on newer roms but i count also on fallen spartan comments and it seems that it is not solved yet

Both the HD's I've got show high res contact images.
I put the images on the phone (created an Avatar folder to keep things neat) then from the contact picked the image.
From what I've read, that's the way to do it.
If you pick the images in outlook then sync, it creates a lower res image and uses that on the phone.
The rolordex screen in album is admitedly lower res than selecting the image and scrolling left and right, but then if it wasn't the rolordex would be a lot more cpu hungry, what with having to display the picture rotated slightly, and animate it as you flick through the album.

[Q] PIxelisation problem on dark/black scene while streaming

Hi! I've got some serious pixelisation/artifact problem when i stream to netflix or youtube.
The problem seems to be related at the black color. Most of the time when there is a dark scene or some black element in a scene i will see some kind of pixel/artifact. I took a screenshot of a scene in a godzilla trailer but ... For some reason it look good while on my tablet its not.
On the picture attached on the left building most of the left side in the black area is pixelated on my tablet (i dont know why its not on the screenshot)
I tried to turn off the adaptive display while whatching videos but... it doesnt help. I also tried different streaming option (auto, low, med, high resolution) with netflix but it didnt helped.
I would like to know if its normal or i've got a faulty tablet (its the 2nd tab s i've got with the same issue).
Thank you
It`s hard to see from that photo, have a search for "black crush" problem that affected Samsung displays in the past, see if your problem is the same, but this problem affects all video not just streaming, maybe it`s a compression problem from poor quality steaming.
I save your photo and loaded it into paint.net app and used the auto levels setting, as from your photo i could only see the center bright section.
John.
I would say it's more to do with the fact that the display has such a high resolution it is capable of showing up artifacts within the video that maybe another display is not capable of displaying.
I know the tab had a high res but this issue doesnt seem really normal to me.
i just did an exchange for another Tab s and it does the same thing on netflix. Is this possible because the resolution of the tab is 1.5x higher than 1080p i've got this issue?
I convert all my video`s to 640x360 on my 10.5" and they look great, so it`s more likely a streaming compression problem and not resolution.
John.

How to get better picture quality on the M8?

Hello everyone,
I recently bought an M8 and I'm loving it so far, except for the camera.
I'm not running the stock M8 rom but the S.Team-JW-7.5.0 rom (HTC 10 to M8 port), so am I missing Duo camera features or something?
Do you guys have any tips or tricks to get better camera results? Both for video and photo.
I know the camera on the back is 4MP but maybe there are ways to get better pictures and video.
Thanks in advance.
This may help
Duo camera works fine on SROM. But Duo doesn't make the photos "better", it just enables the Duo effects like Ufocus, or Dimension Plus.
Hard to know what you mean by "better" unless you can be more specific. What exactly don't you like about the pics you've taken so far? Are they blurry, colors look off, too much glare, etc.?
Number of MP has little to do with image quality, especially if you are currently judging the images on the phone's screen (although cropping the pics, or looking at the pics on a monitor is a different story).
While more recent phones make it easier to take a good photo, very decent pics are quite possible on the M8. A lot can be done with technique. Despite what many folks would like to believe, a lot of photography is dependent on practice and technique, rather than hardware. A few tips:
1) Manually focus on a point (your subject) by tapping on the screen, and then press the capture button. Same goes with video. The video recording often has a tough time focusing on the subject automatically, so its often a good idea to force the focus first, then start recording.
2) Exposure (amount of light) will often change drastically, depending on the point of focus. So again, experiment by tapping on the screen, and you will see the image get lighter or darker.
3) This camera has a tough time with glare (washes out the whole frame), especially sunlight through a window, outdoors in the suns direction, etc. Changing your position, and what way the camera is facing can often (although not always) solve the problem, or at least improve it.
4) Tap on the camera settings, and see if manually forcing any of the parameters results in pics more to your liking. Although to be honest, I use the auto settings 99% of the time. But you can often get better results in certain situations (such as low light or night photos) by manually tweaking the settings. In particular, adjusting the exposure (EV) or saturation ("gear" icon>Image adjustments) may yield results more to your preference, if you find those default settings are not to your liking.

Question Whats wrong with A52s auto white balance

I would like to hear some opinions on this. I noticed some time ago that my videos had very inconsistent colors - there would be visible change of the balance when paning around or filming different objects to an extent that seems odd. After trying out and comparing I did realise that the main camera tends to very aggresively change the auto white balance, even if the scene is basically the same and the phone just slightly changes angle. It seems as it tries to desperately match white balance to every frame and its content (forgive my amateur vocabulary here), which to me seems strange and looking at other phones they just hold a much more consistent balance.
I attach 2 videos to show the issue - keep in mind that the issue isnt as visible always, as I tried very specific scenes/angles to show it.
When I use manual white balance it works great, so it kinda feels like a software issue (?)
Does anybody have a similar experience?
Would you mind trying to film a video in a similar scenario, but after disabling the option "scene optimizer" in the camera settings? I don't know if it does anything, but might be worth trying.

Thanks for the tipp, I'll try to compare it, although I dont think that scene optimizer affects videos
Unfortunately turning scene optimizer off doesnt change it (video attached).
It still feels like a software issue, but since nobody has yet confirmed a similar experience I'm starting to think it might be a problem with my unit. (Btw my A52s seems to have the Samsung image sensor not the Sony one)
Edit: or, I am exaggerating and this behaviour is actually not unusual - havent had a Samsung phone for a few years before my A52s

I do not shoot a lot of video, but in the few videos I did shoot I never saw what is visible in your videos (Sony sensor). It is indeed very jarring. Do you only have it with footage of grass or just always?
In the Samsung camera app, you can go the "Professional Video" mode in the "More" section (so where macro etc. is), and then set whitebalance manually to e.g. 5500K and see whether it is more stable then. But like I said I do not shoot a lot of video, so I certainly do not have experience with that professional video mode.
Edit: I now see that you already mention manual whitebalance yourself. So are there disadvantages to just using professional video mode all the time then?

It definitely gets more visible in outside scenes, more so if there is a lot of green in the frame - indoors and with artificial light it definitely is hard to spot. As I mentioned above it feels like it tries to match the balance to the content or objects of/in the frame, instead of keeping a consistent balance. I had a video where I stuck my hand in and out of the frame and it would drastically change the whole color to match the hand it seemed (thinking about it, the background was grass also, so ...).
Pro mode is a solution, it's just that I'm not a fan of setting the balance everytime I take a video or photo - and the balance ofc affects photos in the same way, as 2 photos of basically the same scene might have drastically different WB.
Nevertheless thanks a lot for your input - I also very much enjoyed your detailed instructions for Gcam usage

You would not have to set it every time (probably). In the Samsung camera app I have dragged the Pro Photo (not video) mode to the 'main bar' (from the more menu you can hold and drag items in and out of the main bar for quick access), with a changed fixed ISO (for shooting of fast action scenes), and you set it once and the camera app will remember that setting forever. And I think for all outside scenes around 5600K WB will work fine (it's not like the A52s is a high quality video machine anyway).
I didn't want to bring up gcam because I had no idea whether that would make a difference, but now that you brought it up, does that have the same whitebalance issues for you (in video)?

I meant I would have to set it again for every scene, but you are right, something like 5600 would probably be okay for most outdoor stuff. And with rearranging the icons it wouldnt be such a hassle. I'll try that out for daily use, thanks!
I am using BSG gcam also, because I find the nightmode drastically better but unfortunately the balance issue is the same, so I guess the balance gets set on system level. I also tried gcam awb but it always seems to be a bit off no matter the config - but I prefer the stock app for daylight anyway (apart from the wb)
