Varying display brightness

Hello everyone,
I've been spending a while trying to find previous posts about this issue, but couldn't find any. Hopefully someone here will have some insight into this problem that at the moment is baffling my friend and I.
I bought an M1000 about two weeks ago. I'm very pleased with it, and haven't had any problems at all - it's great. My friend had a mess about on it and was so impressed decided to get one as well.
His M1000 arrived a few days ago. When comparing the two units however, the screen on my friend's phone was markedly dimmer than mine, and almost seems tinted. After making sure we had the exact same brightness settings and upgrading his rom to the latest available on Orange (mine shipped with the latest version, his was ROM was dated 2003 - I can't remember the version) there was no change - his screen was dimmer, and certain apps were practically unusable (Fade for example).
He took the phone back to our local orange shop and they arranged a replacement. The replacement turned out to have an even dimmer screen than his original (the staff at the store agreed as well) and another replacement was arranged to be delivered.
He got his second replacement today, and that is just the same as the first.
We also noticed that the angle of brightness was different - mine fades when you move the screen horizontally, his when moved vertically. Using the same SPB Plus theme it also appears as if his display has less colours as some areas of the wallpaper appear pixelised whereas on mine there is nice diffusion between shades of colour.
So I guess the question is: have there been different revisions of display on the himalaya series? We checked every piece of hardware and rom info we could and they all matched. Or has my friend been very unfortunate to receive three phones with the same problem?
I can't think of any software I might have installed that enhanced my display and any that we though might have changed a setting (such as nydot) we installed on his unit, again to no avail.
Any insight would be really appreciated. He's really pleased with the M1000, but the seemingly lower quality display is souring the milk somewhat so to speak.
Cheers,
Mista

i remember some posts where people said that htc changed panel manufactor on newer devices
i think that could be the issue

Yes, there was a thread initiated I believe by the user "Pocket TV Team" that discussed the actual number of colours displayed by the Himalaya. Unfortunately that thread (as well as the user "Pocket TV Team") has been lost in the recent crash.
Eventually someone from France stated that a new batch of Himalaya's he had ordered clearly had a less good display (maybe even displayed a lesser range of colours) than the Himalaya he had been working with up to then.

I would welcome a dimmer display, mine is just too bright even on its dimmest setting to make it easy on the eyes at night, and in the daytime i find i only ever need half brightness, the only use i find for full brightness is to use the device as a torch at night !!
Mine is 11 months old now, so maybe they have just dimmed the backlight ?

Don't remeber well the post.. but I am sure to have read about 2 different displays used in Himalaya Pocket Pc.. This explains your friends issue.

Galaxy S I9000 screen problem

Suddenly the screen of my "samsung galaxy's" seens to lost resolution, looks blurred and weak colors.
It looks like when changing the resolution of a monitor to display fewer colors.
Please can any good soul help me?

completing information
I also noticed that the button used to end the call, it seems
orange and not red as it should.
I restored the settings but not solved the problem. I'll try to flash the rom again to see if it works, but seems to be a hardware problem that appeared out of nowhere

That do not sound so good. Looks like a hardware failure to me. Do you have the screen on full brightness all the time? Perhaps you could try changing display density in build.prop and reboot. How long do you have your sgs?

Galaxy S screen problem fault
I am having the same problem. Vodafone Australia stock.
The screen has lost its clarity.
Actually, it appears as though every 2nd horizontal line has been lost - this is quite evident when you scroll through a list that has dividing lines (Eg. Scroll through settings - the separator lines alternate visibly as you scroll).
I've had the i9000 for just under 4 weeks and this fault occurred without any reason (not dropped, no water damage, not exposed to heat, etc). The phone was fine one minute and then the next, it became blurry.
The colours all look flat, the background is no longer crisp black, it is light black/grey as if the LCD that had its brightness settings turned up too high.
Also, tried upgrading Android to 2.2 (from 2.1) and that didn't help. This fault appears to be a hardware fault - you can see the loss of resolution when the Galaxy S logo appears when you first turn the phone on (before Android boots). Look at any curved text/lines and you will see that it appears with jagged lines.
Don't waste your time doing the factory reset, upgrades, etc... It is a hardware fault. I spent a bit of time running the screen through the LCD tests " *#*#0*#*#* " and downloading DPI checkers, etc.. The LCD test shows the solid Red, Green and Blue are ok, as was the dimming test.
The image looks grainy as if it was displayed in the wrong or low resolution. It looks like an old school CRT screen at VGA resolution - almost pixelated.
I have installed the Aries bootloader and the small font text displayed also looks grainy and very hard to read.
Have a look at the two images I've attached.
Real shame, I was starting to get attached to this phone.

First step would be to backup and do a factory reset for any major problem .

I already tried that and it did not help.

Don't waste your time. If you got warranty, you are going to get a new Screen or perhaps a new phone. Go for it.

Did you changed kernel? which kernel are you on?
I had a similar experience (not so bad) when trying some kernel with sharpness and color fixes.
You could try flashing hardcore's speedmod k13c Kernel, it also has some sharpness and color fixes but his work very good.

i don't have thi problem

I have the same problem, just purchased a i9000 four days ago, and it fail after 30 minutes of use .
It si very strange, because if i zoom a image, it will also enlarge the banding gradients (like if the image was low quality)
THe problem only appears wirh dark colors, strong colores dont have any problems.

this sounds like a display problem

Display problem / Weird color stripes

Hello all,
I've got the SGS II for about 1 week now and at first I thought it was a software issue. The thing is, when I'm on a very light colored background ( Market, facebook, whatsapp or whatever ) You see smudged out stripes from the text or any picture that is on there. They're all faded stripes. I thought it was banding but this is something totally different.
What's even more weird- it only happens when I'm outside the house, so my guess is that the brightness sensor plays a part in this? When I'm inside the effect is minimal to none but when I go out or to a very bright place, the stripes are extremely annoying. ( will take pictures for reference when I get the chance )
Would you say this is a manufacturing fault?
Please help if you've encountered something similiar.
Thanks!

Here are some images, the stripes are not that evident right now. They seem to get worse when I'm in the sun.

Looks like some polarising effect.

Should I return to the shop to get this swapped? It seems to me that the screen is defect???

Return!! It seems alot of people are having screen problems.

Same issue on my SGS2.
Was perfect during one week then theses anoying stripes!!!
Did you perform a 1:1 exchange?

There were similar problems on the Sensation forum and it was found to be app/widget conflicts.

If you turn off auto-brightness and also the power saving lcd brightness mode under display in settings does it still happen? You mentioned it happens when you go outside so was curious if you adjusted brightness manually if it still happens

Sooooo....
Yesterday evening I changed form litening 1.5 to the stock rom on KF1 with full wipe.
After that stripes where still there.
Went to bed.
Woke up this morning: Big surprise stripes were almost invisible!!!
Battery 40%
BUT
today I used the GPS google navigation during 1h and discovered that theses stripes appeared again and they are very strong.
- No link with app/widget, nothing installed .
- Didn't touch on settings display auto-brightness before the problem. Tried after but nope.

I tried this today
(all credits to Cost from french forum tmaddict)
Flashlight to use white light during half an hour.
Stripes almoust disapeared...
Then picture with high contrast and color.
Stripes came back.
Conclusion :
With SGS2 you can encounter a display refresh problem.
Not solved btw => screen defect => exchanging it today.

[Q] Green Dots Screen Problem Galaxy S4

I bought a Galaxy S4 i9505, and update it to the latest firmware 4.2.2. After 7 days of usage, some green and black dots appear in the screen and they are blinking randomly on the screen (Please see the attached screenshot. The site uploaded the images in very low resolution and think the dots cannot be seen).
I think is a software problem, because it also appears in the screenshots.
Did anyone see this problem before?
P.S. I have already done a factory reset but the green dots problem still remained

I think that u have Deadpixels. Try a pixel test from the app store.

Thank you for your quick response. I don't think they are dead pixels because they are appearing in the screenshots. If they were dead pixels they will not be able to appear in the screenshots because this is a hardware problem. Isn't it?
i.e Think about your computer and PrinScreen Button. If you have a dead pixel on your monitor it never appears in the print screen picture.
Also, these dots are randomly produced anywhere and they are blinking all the time.

Hi there,
I have the exact same problem currently running 4.3 XXUEMI8, however it has been a problem since I bought the phone brand new from stock.
Refer to screen shot attached, where the pixels are clearly visible at 1:1 zoom.
The green and red pixels are also very visible when viewing YouTube videos or anywhere that is displayed as solid BLACK or WHITE.
Did you ever find a resolution?
Here is a link to a full resolution image (XDA image uploader masks the pixels on resize): osiris-developments.co.nz/temp/Screenshot_2013-10-09-15-59-39.png

ohh! I am so sorry about that. Exactly the same problem. Also, when I took pictures, they were fine, but when I made video calls, I saw the dots to my pc screen. I thought is like a VGA problem. If so, the damage is very huge, and maybe the motherboard needs to be replaced.
I didn't find any solution, so I sent the phone for a repair. A month passed, no news yet. I suggest you to return the phone as soon as possible!!
When I have news, I will write back to you.

Just to follow up on this, phone was replaced under warranty. Samsung did not specify what exactly was repaired, however it was turned around in about 3 working days.
I have since moved to the G900F anyway

Yoga 10 HD+ - display issues - oversaturated and red

Bought new yoga 10 HD+. Everything seems to be really ok with it except the display. Colors are extremly oversaturated and are falling deeply into reds, especially on skin tones. Actually, all of the photos with people on them look like there is definitely something wrong with them - see the image attached (yoga at the bottom, all screens set to max brightness).
Is there anything wrong with my model and I should return it ? Or it's just a characteristic of IPS display installed on yoga, and if it's display - is there any way to tweak it ? I use my tablet mostly on trips to browse and upload photos. With issue like this yoga is useless for me in this aspect.

I have the exact same issue. I cannot find any app or menu on the tablet that would change the color profile very annoying

Try filter your screen from Google Play..

Bug
This is due to a bug most likely as it happens to more people including me.
https://forums.lenovo.com/t5/Idea-A...e-stand-mode-not-working-without/td-p/1690111
What happens is that the color mode gets stuck on one setting and does not get switched to anything unless yo do a full reboot.
I hate it but not much to do except keep rebooting and waiting for a solution.
