Varying display brightness - MDA II, XDA II, 2060 General

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.

White Screen??

My Cingular 8525 is having screens issues that I thought I'd post to the community if anyone has seen this.
The normal screen will go to all white under thermal conditions it appears. Thermal being inside a hot car, in my holster against my hip, gripping in my hand, heavy use with BT or wifi... thus I suspect thermal. I've changed battery's, no change. If it has changed to all white screen, a soft reset will not revert the screen back. The pda appears to have to "cool" off before screen will recover.
Could this be a LCD driver chip dieing? The screen itself? Worth repairing? Got my eye on the AT&T Fuze but wanted to keep the 8525 going for a few more months.
Thanks, Craig
holy crap I'm having the same problem. I havent determined heat to be the problem, but the only possible clue is that once, right after i hung up ona phone conversation, the screen turned semi white. If you looked real hard you could tell that the menus and programs were still operating normally, but the screen was screwy. using johkoss's V8 w. Manilla2D
Major problem, theres a MASSIVE thread going for this, sometimes it pays to use the search function.....
this is "the most common issue" on a hermes device.
I, personally, experienced it 3 times with 3 different hermes. Each time I had to send the device back to the shop. Because my device was under warranty, I always got a new one, free of charge.
You guys might want to check the Wiki, cause I believe there's a section there just dedicated for this issue.
I can't remember what the details are, but if my memory serves me right, it has something to do with the hardware (connection of cables to the screen).
I don't use hermes anymore, but I still come to the hermes forum every now and then...
Therer are actually a myriad of reasons you can get whitescreen, both hardware and software. From the descriptions though, it sounds like hardware.
This can be one of the most difficult things to fix as there may be multiple reasons and fixing one thing won't fix the issue.

I am agree with you. White screen may be appears occasionally and may be not. When white screen appears in my experience, it's enough to soft-reset.
May be different solutions with another?
HTC TyTN White Screen Issue with S/N Starting with HT6's
is your TyTN S/N start's with a HT6 you have a defective model for sure they are one of the first breads and are being known too have issues, so anyone make sure it starts with a HT733G4323 Etc, if your buying one of these used.
Or Even new Watch Out.
HTC TyTN
1.10
mobile 5
With 6.1 Plug-in's
Can't say that MY HT6 is a problem.. I actually found it faster than a HT7 (I have both). I did have to replace the LCD, BUT, it was because the touchscreen died, NOT whitescreen.
I bought the HT7 as a broken Hermes off ebay and found that it was actually less responsive than my older model. Used it to fix my older HT6 than use the HT7 motherboard in my, now, Frankenphone....
The "broken" Jasjam had a broken camera. It was actually just unplugged from the board. Liked my older model better...

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.

[SOLVED] Phone back from HTC service - differences...

Motto:
If you ever walk down the stairs wearing slippers and talking on the phone make sure your free hand is next to the stair handle...
The phone went down through the staircase gap - from the 1st floor directly to the ground.
Aside from the aesthetics and the potential hazard of small pieces of glass going down my ear, everything seemed to work and I could use the phone with full functionality.
I just recieved the phone from the local HTC service after 2 weeks.
I thought only the digitizer will be replaced but instead they replaced the whole touchscreen assembly with 200 Euros:
- screen (digitizer + LCD) ~142 Euro
- middle chassis ~18 Euro
- keypad ~23 Euro
- service fee ~17 Euro
I was told they couldn't replace only the screen because the whole module comes pre-assembled by HTC.
I still don't believe that but I decided not to reject the repair (+ find another service + wait a few more weeks + risk the same or other issues) for the extra 40 Euros...
After thorough testing all day long I find everything is in place but I also notice some differences compared to the original:
-the green LED is not working;
-the screen is noticeably darker on auto-brightness level
I don't think it's a software issue because I reflashed the stock ROM and also the light sensor works, so I guess:
- either the hardware parts made by different OEM are not the same
- or, the sensor and speaker modules weren't remounted properly
Anyway, for now I'm happy to have the phone back and thought it would be nice to share my experience with you...
Edit:
not only the screen is definetely darker in any OS (WM6.5, Android, WP7) but the whites have a subtle green tint
i'm afraid i'll have to send it back but i'll go with another HD2 this time, to prove I'm right...

yea deff send it back. they use returns for parts, so you probably got one that some minor tech took a quick look at and thought 'yea that works' and put it in the spares pile.
thanks for the advice samsamuel
this cannot be "htc authorized" service quality, i am very disappointed...
im 100% its not original lcd... i change lcds ( not hd2 ) every day and how you described definitely thats not right lcd... so like samsamuel said send it back.
things start to get wierder...
the screen seems to get better by itself
to be sure my eyes don't fool me, i compared the min-max backlight levels against both another hd2 (in android) and a desire.
i don't understand how but it looks fine now, even the colors. i use a custom color for the live tiles in wp7 - yesterday it didn't look ok, now it does...
still, the green notif led doesn't work but i don't know if it has anything to do with the screen. as i saw in this video, it looks like the notif leds are integrated in the receiver:
http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked
the most annoying issue however is something i discovered only yesterday. the g-sensor doesn't work at all in any android buid. what's strange is that it works perfectly in both wm6.5 and wp7...
as i found out, i'm not the only one having this issue:
http://forum.xda-developers.com/showthread.php?t=1069578
it's like i'm playing in a "twilight zone" episode...
UPDATE:
the phone came back from the 2nd trip to the repair shop.
- the issue with auto-rotation in android was related somehow to the compass (magnetic field sensor) which apparently didn't work in any os - solved by motherboard replacement (under warranty)
- about the screen brightness - it's not a bug, it's a feature - as i was told, all the screens in the new batch from htc have a slight yellowish tint (visible on white) and i have to live with it
- the notification led works now

How i fixed the YotaPhone2 e-ink screen problems

Hi,
many of Yotaphone 2 users complain about their e-ink screens, that are not completly black if needed, too grainy or some fading different bars of grey (a scale of w-b rainbow) instead of one shade of black screen.
Others complain about ghosts problem.
There are some advices to fix the problems like:
- to uncharge the battery to 0% and keep discharged for few days,
- to downgrade Android to version 4.
Sometimes it helped sometimes not. In my case that did not solve e-ink problems at all. I have tested androids 4,5,6 and few times discharged the battery and left it so even for a week.
When i came to terms with a problematic e-ink screen and decided not to bother my head with this anymore, the solution came
One evening i took my YP2 to my pocket, plugged earphones and went for running for about 30 minutes. The phone was jumping and shaking in a pants' pocket (which is not tight) during my run.
I got back home, leaved the phone on the table for the night (even not looking at it) and the next morning there was a big surprise, a perfectly black e-ink screen. No shades, no bars, no ghosts. It has been working perfectly for a week now and i hope this fact will not change
Try it and give here response if my advice help you or not.
My YP2 is chinese YD206 changed with Android 6.0.1 RU version (1.1.47) to YD201.
Best regards,
Peter.

Hi, do you wish to suggest mechanical shock helped the display to settle into a uniform state? Considering that the EPD does involve an electromechanical mechanism for changing states, yet it's practicality is uncertain.
^ I think he means sweat, I'll dump my phone in to the sea, expect reports in 10 hours
My "broken" line appeared after running battery tests on different roms, so I think heat causes it. So far I have not seen any reports of fixing e-ink screens with thise kinds of problems. My kobo reader is perfect after almost 6 years.

Yes, mechanical shock was exactly what had helped with the epd problem.
I know that seems to be wird but it really helped. My EPD was not functioning properly since purchasing the phone as new one about 6 months ego.
Non of advices available on the Internet did not help. Maybe there was some poor connection on some electrical terminal of EPD until mechanical shock improved the connection or something like that.
I am really curious if my notification on EPD problems is going to help other poeple who strugled to solve their EPD problems in vain.
Just wait and see.
I have to add that now i really like my phone. The dark theme is awesome!
I drive scooter on bumpy road and it has no effect on my e-ink "dead" line.
I am afraid dead line is more serious problem and requires display replacement. I never had dead lines problem. My EPD problems were: ghosting, too grainy, too bright and b-w rainbow scale in the background instead of one shade. Dark theme was unreadable, white theme was better but still not perfect.
My Yotaphone developed dead lines yesterday, and I'm not inclined to use it anymore. It's difficult to understand that the feature they romanticized the most, is inherently flawed.

LeEco Pro 3 Display

I have this beautiful and powerful phone LeEco Pro 3 that i`ve been using for half an year or so with AOSIP ROM. Its a wonderful phone with an amazing performance.
The thing is my display started a problem history that has become a long history i will try to resume in a few words.
It started in one day i pressed the power button in order to light the display on and check something in an APP i needed. I found out that before the display lighted on some weird colors and artifacts appeared on screen. But indeed the display worked fine.I thought it was just a temporary thing and just kept using it until In the second day that the weird colors and artifacts became permanent, so i realized i was in trouble. :crying:
Tried sending the phone to technical assistance.
The first one - Told me that they could get a new display for testing but indeed the results were the same and they were seeing oxidation in the display connector on the board, not the display flex cable but the main board connection. They said they would not go further into it and they decided to give the phone back to me. Weird thing is that when i turned the phone one it worked for one day without issues. He said the phone was in the same condition, but that is not what i saw. The problem indeed happened again one day later , but it was less worse as i could at least see the screen, but almost half the screen was horribly shaking, trembling.
The second one - Once the tech guy looked the phone he said he didnt see any sign of the phone getting opened. He said he would be seeing signs of glues or anything like that but in his opinion it was definitely not opened. But he warned me the display could physically brake once he opens it as the phone got contact with oxidation in the toilet(I used to left it in the toiled while i take bath). So i was afraid and decided to back off.
The third one - Said he could not find any display so he sent the phone back to me. Didnt open it at all as he was trying to wait for the new display to arrive in order to be safe. They said they are 90% sure its display replacement would do the job. The thing is - if i used in hot environments the issues seems to slowly disappear . If i use it in cold environments the problems seems to get worse
So here i am. I CAN buy another screen over the internet. But i am afraid if it will work or not. Have anyone there faced same issue? What do you recommend me to do? What would you do
Thanks in advance

There are many many post on this subject, recently in fact. That has links. In fact, you can find them on Alibaba that are all black and made specifically for the Le Pro 3. Here is a link of a guy who used the cool s1 display
Yes it sounds like the display or the flex cables.
Link 1
Here you go cheap and they have the black one
