Grey/Transperent colors with green/yellow tint - HD2 General

Today my hd2 has shown some strange color issues: Grey / Transparent black causes a grin/yellow tint. I did the usual troubleshooting (soft and hard reset) but it did not help. I also read some old threads about it saying that I should flex the screen to make it go away (http://forum.xda-developers.com/sho...m.xda-developers.com/showthread.php?t=1003265). I tried that without luck though I'm not sure if I "flexed" the screen enough but I'm afraid of breaking it.
Anyone an idea what caused this problem? I did drop the phone a few times over the years, however, today, when it all started, not. Secondly, I can't really think of a broken screen as it seems that only a specific grey is tinted yellow/green (the grey whatsapp uses for their contact without photos and the grey used for the keyboard when you eneter your pin.
Any help is really appriciated... Don't want to loose the king :crying: as this color issue makes really unconfortable.

EDIT: I'm on a european hd2 with the latest Pdaimatejam WP7 rom (v8.2) and I even tried to reflash the rom... Seems a hardware fault:crying:

Today morning the issue faded away without doing anything at all . Might be that the screen got somehow pressure causing some disorder of the fluid crystals and with time, they reordered themselves...

White Screen

I recently bought a cingular 8525 on ebay. The seller said it was stuck on a 3 color screen, blah blah. I knew I can fix it if it was stuck on the 3 color screen, but I turn the phone on and the screen is just white. I was wondering if this means the device is bricked, and if there is any way I can fix this. I've tried a hard reset.
It's called the "White Screen of Death." You can read more about it in the wiki or here.
I'm not positive if it's that or not. I don't see a complete white screen, I see streaks of gray on the left side of my phone. I have a picture, hope this helps. Is this the white screen of death, or do I just have to replace the lcd screen?
If you see the booloader screen at times, then the lcd should be fine. If not, then it is in fact the WSOD.
Nope, I don't see the bootloader screen at all. I just received the package today, put in the battery, turned on the phone, and just a white screen. Nothing else. Doesn't do anything but sit in a white screen with some gray streaks.
I fixed up one White Screen yesterday , that is , white screen before,and display normally after.
I just flash the phone with the origional rom, and after a bootloader reset( OK+power+reset), the white screen magicly start to display stuff!
So give it a try!
^^ Thanks for the help, but I already tried updating it to the official WM6 rom and it failed.
Ther are about 1001 things that can cause the WSOD - somtimes software, sometimes hardware and sometimes multiple things. To track down the cause can be a major headache and even if you do fix one thing you may have something else causing another problem resulting in WSOD... Most people advise NOT to buy a 2nd hand hermes with this as it is too much of a pain to fix. If you want to try however, you can purchase new LCD's off ebay for about $100AUD and you'll need the HTC service manual to take it apart..

Make sure you have a number 6 torque key, a small flat blade and phillips head screwdriver.
All the best...

[Q] Strange Screen Issue: Is it the end?

So i've had my Nexus 4 for just over 2 years now. It's stuck by me through thick and thin, i think this might be the end though.
Anyway, so i picked the phone up at around 2 am this morning, it had been working perfectly all day up to this point. So i picked it up, the colours on the screen are a bit weird. I change what's on the screen and the colours remain weird, so i do the standard thing of a reboot to see if that clears it up. This is where the big issue comes in, when the phone turns on again, there's a 1 cm wide black bar on the left side of the screen. Nothing appears to affect it, but sometimes it randomly appears greyer than others.
The rest of the screen has the same weird colours as it did before i restarted, kind of muted, and moving light areas on the screen (like app icons) makes bars of lighter colour move across the screen with them.
If i didn't know that the phone hadn't been dropped i'd be saying that the screen was just broken right now. But i flashed CM12 (was on the latest PA beta) and when the phone was restarting the whole screen flashed working for a split second before going to its broken state again. This hints at the issue being software related, especially given that it initially happened with no physical damage occurring to the phone? When thinking about this, the colour issue reminds me of what happens when you installed CM11 with the wrong kernel and it looks messed up...
Anyway, I think my phone is dead, and i'm posting here in case someone has some genius idea as to what on earth killed my phone.
I'm pretty good at doing stuff with the phone, so can flash and install whatever, hindered only slightly by missing 1 cm of the recovery menu. I would take pictures, but normally i use my phone as a camera and...... If any more info would be useful then please ask!
Thanks for any help, ideas or input in advance!

New Note 3 screeen showing unusual behaviour

7 days ago I have purchased this new note 3 N900 , the screen today is acting in a weird manner.
Here is what happened, I switched on the phone and then there was only the wallpaper and a dark triangle on the right side of the screen, I rotated screens but the thing remained the same, that is only the background with a dark triangle on the right side of the screen with a little flicker so I had to restart the phone.
Now it's working fine, please suggest should I get this phone replaced, is this some kind of hardware issue.
Also I had purchased a cover for the phone which was actually very hard to remove and I applied a lot of strength on the right side of the screen to get the cover removed, can that have caused the problem.
Also is there any app which I can use to check is there is a problem with the screen or not.
Thank you for your time, please give your valuable suggestion.
I'm running stock android 5.0 the same software that came out of the box.
The screen roughly looked like the image attached below -
Forgot to mention above that earlier I also had this issue where the all apps button on main screen turned to blue while everything was working fine and won't change to normal so I had to restart the phone again in that situation which did fixed that problem.
Would it be possible for someone to clarify that is this some kind of problem cause due to applying excess pressure as the Urban Armor Case I have purchases was really really hard to remove so I had to apply a lot of strength on the right side of the screen, it was so hard to remove that even the official back cover came off with it, can that have caused the issue or is it just a software problem.

Yotaphone 2 ereader screen problem

I have yotaphone 2 from tinydeal germany. (I think they flash the ROM to change the language.)
The phone worked fine at first but now the e screen on the back is doing strange things, leaving images of previous pages showing through the current page. This means, for example, on the clock face the clock is faint on a grey background and as the fingers move they leave a black after-image. Pages that should be black look speckled grey. Any suggestions for cause and a fix?
Unfortunately this is how (older) EPD screens work. When updated they somtimes leave a ghost image behind. To eliminate this the screen needs to be flashed white/black/white before redrawing and with the low refresh frequency of EPD this results in a very flickering image. So there is nothing wrong with your screen, this is just how EPD screens work. See also here https://en.wikipedia.org/wiki/Electronic_paper#Disadvantages
Thanks, but this ghosting or layered imaging is much more severe. I know someone else with the same phone where black is black and whilst there is very slight ghosting of things like clock fingers it is nothing like this current phone. The phone was fine when we got it, and the layered/grey imaging has started without me doing anything. I only mentioned flashing of the ROM because Tinydeal have told me that that is what they do to change the language on these phones.
So from the Wikipedia entry and your comments I now assume that the phone should automatically flash black/white between page changes but it isn't doing it.
The ghost images don't appear if you load something like chess or sudoko onto the rear display but appear again as soon as the regular Yotapanel or Yotacover is used.
I have the same problem, but only when the white theme in the Yotahub is turned off (so the dark theme is active) or when I use the Yota Mirror. The ghosting is terrible. When I use the white theme, it looks like it should look. I am not aware of any changes I made to my phone yesterday, but in the afternoon this problem started.
Does someone know how to check if the screen is flashing/refreshing correctly and if not, how to repair this?
Update: when I put a completely black screen on the back, it is spotty. The black is not black, but dark grey, and there are many lighter spots on the screen.
Update 2: the white theme has this problem too, but less visible. The white starts as real white, but because of ghosting becomes slightly grey. With black it is much more noticeable, because black does start as dark grey.
Well this may only turn out to be a temporary fix but I went through the Yotapanel pages repeatedly and very rapidly using the bottom of the page buttons.
I got all sorts of shades of grey and multiple overlying images but then the phone suddenly showed a clear black and white page with clock.
Ringing the phone from another phone produced a clear missed call message on the back of the phone and then after a minute the clear black and white clock page came back. I am leavng the phone without looking at all the othe Yotapanels or the Yotacover for the moment in the hope that something just got out of phase in the software and the phone might now settle down to correct operation again.
I have the same problem. It has started a few days ago and it gets worse every day.
Unfrtunately the problem has returned on my phone although I was able to get back to a black screen with the clock after three page changes using the bottom left arrow. This time a missed call message came up very clearly on the back of the phone but after the missed call message cleared the whole of the back of the phone was speckled grey with a very faint clock image. One question though: is this just the phones from Tinydeal where they have apparently flashed the ROM, or is it all phones?

That's the app for Nook ereader to refresh its screen and get rid of ghosting. Works also on Yotaphone.
What always works for me to clear the screen when the ghosting annoys me is to switch to Android on the EPD screen (by holding the circle button and choosing the left option) and switch back right away using the same procedure. This always leaves me with a clean black back.
Thanks Keeper and VirtualL.
Tinydeal asked me to upload a video to demonstrate the fault, and no sooner than they did that the phone started behaving normally again!
So if it goes again the first thing I will try is that page sequence, and if it fails the App.
I have to say that these are really fantastic phones. I think that a lot of original reviewers completely overlooked the basic issue of not being able to see a phone screen in bright sunlight, but that the yotaphone overcomes this problem.
Resolved by switching the back to front screen views a couple of times. Getting the front screen to mirror on the back seems to give that hard black and white interscreen flash that clears previous images.

I don't know if you already use it but this widget makes it very easy to switch between mirror and back. Just one click on the widget.

Last week, I got a chinese version (YD206) through GearBest. I had the same problem what you mentioned. (Black was always Grey and was never black and lot of ghosting). Until yesterday, I used to think that's how the e-Ink display works so I was using White theme all the time.
After seeing your post, I tried using Nook cleaner software and it did not help. Then, I removed the screen protector which the phone came with. For the next 1 hour, I did not see any difference. I left it thinking it could be ROM issue.
But, after few hours, I noticed everything became normal. Now, the e-ink screen looks goergeous in BLACK.

This issue keeps coming back and I am not able to find a guaranteed solution to this.
Like you described, activating and deactivating Yota Mirror in quick succession clears the ghosting and makes the screen BLACK. At other times, it does not work at all.
I even try swapping to different Yota Panels, but it is a hit and miss. Is this issue specific to Chinese version of YD206?
How to solve this issue permanently?
If not possible, is there any known step which I can do to clear the ghosting?

I have the same problem with a GearBest YD206 running Android 4.4.3. Would updating the firmware change anything?
Hey Yotaphone Users!
I finally have a solution for this problem, that I received from the Yota Phone Support:
"If you see that ghosting is amplified, try to do some steps. Try to discharge the phone completely. Then leave it discharged for long periods of time, f.e. overnight. Then charge the phone to 100%."
For me that worked perfectly!
For me the discharge-recharge didn't work at all.
Discharged untill it switched off. Turned it on again untill switched off, untill phone wouldn't start up again. So: battery was flat.
What happened was: EPD turned black. Yohoo! Happy!
But: after one night discharged, i put it on charger again. Screen switched on, and ghosting was immediately back.
Disappointed. Very disappointed.
Anyone has a different solution?

Sad to hear that.
Did you remove the screen protector from the back side as in the post #14 the user said that after removing the epd screen became normal black again?
Has anyone heard and try heating with hairdryer the EPD screen for 2 minutes (not too hot) to eliminate ghosting?
