[Q] Camera flash is out of sync (dark photos) - HD2 Android Q&A, Help & Troubleshooting and Genera

Since I couldn't find anything about this (maybe wrong keywords for google search, but I sincerely don't believe this is a frequent problem), I decided to post question here; at least you'll tell me there's nothing I
Since I disassemled my device to the core and assembled it again, the camera flash light is too harsh. Looking into it causes eye sore and it overheats in seconds. It felt sad at first but I coped with it (and I don't consider it an issue, you don't have to address these facts; they serve only as a side-info).
However, what bothers me much more, is that somehow the light managed to get out of sync when taking photographs. Now I lost the ability to take photos of documents. Even when there's enough light outside, when I don't turn off the camera flash, it makes the photo even darker and text illegible. It seems as if the flash came out too soon, or too late. I'd love to get this fixed somehow.
The question is, is there a way to calibrate this? Or a file/driver, where to modify some numbers to get this aligned? I know it sounds pretty naive, but I already lost hope that anything could be done and than realized that the xda-developers forum is still the last (and best) option.
Looking forward.
<edit> also I was just trying to make a video w/ the flash on and he usually won't survive such attempt for more then a few seconds. Same goes for using phone as light (but it can last for longer time). Interesting is, that after a few seconds the light gets a blue tinge. I think something like reducing the power that goes into it could be helpful in this manner, but I don't know if something like this is software-modifiable

Blank Pics From Camera

Just wondered if anyone else has experienced this - when I take pictures sometimes, they are all blank - i.e. just a grey canvas.
It only seems to happen in bright outdoor conditions...
Cheers,
Smiffy.
Yes that used to happen to me when running black 2.5 but it didnt matter if i was outside or inside the camera would just not take a picture and it would be a blank black/grey if you look close when you take a picture that works it takes a second or two to load up and be put into the memory with the blank ones they load up right away almost like the hermes is not storing the info of the picture properly
i had this happen a couple of times too, usually restart and its fine.
This occurred on my device when using the 2mb pixel size(the largest) with a deep field of focus...like outdoor pictures. I fixed it permanently by installing the latest firmware/os from my provider---cingular. Your mileage may vary.
As long as it's not hardware, I don't mind
I'd hate to have to try and convince the guys in the shop that yes really, t-mobile have released a WM6 ROM and it's official and still under warranty ;-)
Smiffy.
I had the same problem. I think it was comin' from an RSS software. It happened even after a soft reset.
After removing the software, it happens once a long time. Which is ok, just close the camera and start it again, it'll work if not.. poke it on the underside, u know which hole
It's the Super Fine setting on the camera that does this in bright outdoor conditions.
Switch to a different quality level and I bet it won't happen again.
Hi,
I experienced it too, but I catch the issue, because my camera said that my memory was full... but it isn´t full. I just closed all apps but camera and it magically started to take good pics again using 2M resolution and super fine quality.
Regards,
Taguapire.

My Camera

First of all.Sorry if there's another post about the same problem.
For some time now my G1 has been taking some very strange pictures.
Im not sure if its the lens or w.e but when I try to take a pic, the screen always looks in weird colors like green, purple, red, etc..
I was just wondering if anyone knew what this was, why and how it happened, and if there is a fix for it. I am hoping its not my lens
I had the same problem not that long ago
http://forum.xda-developers.com/showthread.php?t=603900
That's the thread it was talked about in, seems most likely that it's a hardware failure, I used T-Mobile's warranty service to replace mine, if you're phone is less than 1 year old, I'd unroot it and do the same
If you read the thread I posted there's also a suggestion to replace the camera itself, other than that there was no easy solution, definately not something as simple as flashing a new ROM or restoring the stock build
ok thanks dude
i have a problem almost like that, except it's only showing weird colors on the thumbnails but when i view the actual picture it looks normal.

Screen burn in

I was playing a game last night when I have noticed that where my baterry icon and clock is, the screen is a bit grey. Now I have been reading on this forum a lot about amiled burn in but how is it posible to have it that fast?
I mean I have this phone for like 7 months and I allredy see this burn in effect.
Is it normal to have it that fast?

7 moths is more than enough for burn-in...
it begins in 3 months.
should consider yourself lucky if you got it in 7 months.
a word of advice, just ignore it.
don't take it as a big deal or you will just be annoyed all the time lol

Well even though its understandable that the pixels there will wear out eventually being always shinning
I believe its more susceptible for having the screen ON with a static image which includes browsing, google reader, etc meaning all apps that have the status bar ( not fullscreen mode) for few hours (not minutes)
Also OP there is a slight memory effect in my opinion on these screens, means that when you switch from status bar to non status bar screen you can notice it there (grey background mostly).
To be honest, it is very very hard to notice that there. The only problem is I have been planing to use this phone for at least 3 years.(I realy like this phone), but if the burn in goes so fast I won't think it is possible.
I wonder how much a screen cost. Doea eny of you know?
Sent from my GT-I9000 using XDA App
One way to reduce the chance of burn-in is to reduce brightness, and avoid static images on screen. In Launcher Pro I disable the status bar for this reason.
I've had my Galaxy S for about ten months now, and still no sign of the screen burn.
I haave put my brightnes on automatic.
I won't disable that bar because it is to practical. If there could be a way to auto hide it somehow.
Btw: thnx all for the tips and for the fast answers.
Also sorry for the writeing mistakes to.
Sent from my GT-I9000 using XDA App
My SGS is 5 months old now and i never put brightness to automatic but 35-50% and still there is no such sign...
I have it since 2 months after purchasing, Display ist always auto-dimmed.
On the picture u can see the clock and some of the battery indicator.
I have pretty heavy notification bar burn out on my Galaxy S after 5 months of use. I'm now using the Launcher Pro hide notification bar on the home screen settings, however the damage has already been done.
I also don't think that the damage arises from the home screens since we spend more time in apps and browsing then in the actual home screens.
Google prohibits hiding the notification bar while your in an app for some reason. They claim that the notification bar is integral and essential to the android OS that's why devs can't simply hide it or remove it from their apps. It's a shame and there was a thread started on google code about AMOLED screens and the Android Notification bar causing burn out.
Check it out here:
http://code.google.com/p/android/issues/detail?id=9063
The request to hide the notification bar was denied by Google.
I just checked it again by *#0*# and then click blue and i can see "AM" visible @ upper right corner & some shades where there is battery icon. It is not prominent and only showing over blue background but still it is annoying....
Is there a way to fix it?

AM would suggest you use your phone in the morning more then the evening right? I mean if I would get a burn in it would be a combination of PM and AM (oh I use 24h but just hypothetically)
So either you really use your phone more in the morning OR you left your phone on for a longer period when it was AM time OR what you see is not a burn in, just a "slight" memory effect that could wear off (doubt that). However I would go for that second option, that means leaving the screen on while AM :/
There is no way to fix it. Fixing it would mean to let the other pixels wear out whilst the AM space would be saved. On a plasma/lcd (PC/TV) screen you could do that and I bet the first one who does some APP like this for android will make money from it. But to actually decrease life of the other pixels just to have it even would make your screen loose color etc etc etc. And imagine to wear out the WHOLE screen just to hide the AM
Dont know if there is a way to "infuse" life into the aging pixels. Would be awesome.
The thread about hiding the bar. I think google should give in and let us make it hide able. However I think a better approach would be to acknowledge this a manufacturing defect of amoled screens and for Samsung make way of prolong the life. Something like they have on plasma via pixel shift/double pixels (but no all active like on the next gen of Amoleds) etc (wont help the burn in in long time, but will for sure prolong the life )
It is not just samsung. Nexus one has the same problm with the screen from what i know.
A good program to try and fix the problem is the jscreenfix that is in the market( that is if it is a 'memory' problem). and also ffor others to check if they have wear out problems see: "dead pixel test'

I wouldn't call this a defect really.
OLED is a new generation technology and thus, it has many disadvantages as well as advantages.
I'm sure it will get improved in no time.
People who bought the phone should have really researched before making up their mind

There must be some sort of memory effect adding to this, since on mine, when I notice the problem, I can virtually read the current time! The hours are clearest, and the minutes more blurred as you would expect... but this and the even clearer AM / PM part suggests that part of what is seen is the memory of what has been show recently. Note, I'm not saying there isn't permanent damage too, as I'm certain there is, but I haven't figured out how long the memory effect lasts for, and therefore a suitable means of removing that from the equation to see what is permanent damage.
If you could leave the screen off for (say 12 hours? or maybe longer?), and then get the device to wake-up straight into a full screen coloured graphic (without showing the status bar even briefly), you could be more sure what you were seeing was the permanent state of burn-in. Does such a testing app exist, or could one be created?
Mike
I think it is PM, not sure as P or A is not clear but M is easily visible... And what is this Memory effect? Any solution for memory effect?
Burn-in would be permanent damage to the screen. It would be caused by those pixels being used more and "wearing out" quicker, and would be visible as those pixels being degraded by always displaying less intensely than those around them. Hence being visible as a ghost image of the signal strength, battery meter, time, AM / PM etc.
Memory effect (assuming it really does exist - as I suspect) would appear to be the same thing, but only on a temporary basis. i.e when the time and signal strength meter etc. has been displayed for a while at the top of the screen, and you shift to full page of a suitable colour, you would still faintly see the time still in that corner. However how visible it was would depend on how long you'd recently had the screen on for, how brightly, and how recently ago those screen pixels had been used.
The main difference between this and burn-in would be that leaving the device/screen off for while would reduce how visible the ghosting was.
So:
If what we were seeing was only memory effect and no burn-in, then leaving the device off for a while would cure it completely.
If what we were seeing was only burn-in, then there would be no difference based on recent usage... the ghosting would remain at least the same, and in fact slowly get worse each week or month.
If, as I suspect, both have an effect, then there is slowly increasing permanent damage occurring, but also, it will look even worse when the screen has just been used brightly. Leaving the screen off, would reduce a proportion of the damage.
Since I personally mostly use the screen at minimum brightness (and even have it extra dim at night using "screen filter" app set to 10-15%!), mine does definitely have some permanent damage, but might have a lower proportion compared to someone who uses the screen on full brightness all the time. So using the time as an example, I can see the current hour clearest, and if the screen has been off a while, my ghosting is quite dim and blurred (but still visible).
Someone who has more major damage, might not be able to see the difference between memory effect, and burn-in, as their burn-in would be too prominent.
First time a new phone is used, it shouldn't have ANY burn-in (unless factory testing left some), but would still display some memory effect.
Over time, the permanent burn-in would increase to the point where it was ultimately FAR stronger than any memory effect. In between these two extremes, is where I suspect most of our devices sit, except for the heaviest users!
This is my experience and hunch, but I haven't been able to definitively prove it.
Oh, one final difference between memory and burn-in. Memory effect will be overall crisper and influenced by the most recent usage ("A" or "P" will show more strongly based on which was used most recently.. and hour might be crisper than minutes), whereas burn-in will always be more blurred in areas that change (i.e. all time will be very blurred) and only the most permanent features will be crisp (i.e "M" in AM/PM will be crisp).
Be good to hear from others if they can prove that they get a mix of both types of ghosting, and if we can get an idea for how long the memory effect lasts.
Ironically, one good place I can see the ghosting is on the light brown splash screen for the XDA app!
Ideas for testing:
Leave screen off for a while (longer is better - maybe overnight?). Turn on, and immediately open the XDA app, and see the level of ghosting in the top corner. Note how blurred the hours are, the minutes are, the A / P is, and the M is. etc
Then use the phone for an hour solid, and test again, and check for the same blurriness.
After that second test, if the ghosting is overall more prominent, and you see the current hour and the A or P particularly more clearly than before, then you have just proved you have a mix of memory effect and burn-in.
I expect there to be a range of answers depending on how old the unit is, and how well used it has been (most used screen brightness level etc), so when reporting back, please include than info.

I meant Samsung as a Amoled screen producer not just a smartphone one . Oh really jscreenfix is in the market cool I have bought from them the java version (for PC and TV) longer ago

Sorry for use of stronger words. But this is BS the last part about my researching. I should have researched into what I am buying to? Its not a car or a flat to spend hours on forums searching for every little bug it can have. Also in the time most ppl was buying it. No one knew about this. I dont see any warning on Samsung manuals and etc. I am a consumer and not a researcher. Every plasma tv has a warning the lack of amoled warning is NOT my fault. Thus once I see it I will make my warranty claim
But yes that it will improve
Just saw this thread n wondered if some might actually benefit from this :
Its zsjpj's framework-res. It completely disables the status bar, so you won't have it anywhere in the rom.
Just push to phone as framework-res.apk and reboot.
Link
Use at own risk and only flash if ur familiar with adb. Hmm it worked once, now it doesnt.
Gonna give editing another shot 2moro. U can give it a shot but make sure u back ur framework-res to restore after.
hey
after reading this thread i want to test my samsung , which is 6 months old , too. Red and Green display was okay, i dont noticed anything. But with blue i got the same problem like all of you. i see something like 18.xx o clock... sucks but you have to look hard to see it.
But i dont give a **** ;D

Artefacts on the screen

Hello everyone,
Got a problem with my Galaxy note 3 amoled screen. Couple months ago some lines appeared on that, look like artefacts or dead pixels or something, not really sure. Didn't drop/drop in water the device before that. No idea why that happen. But, they don't go.
Tried some dead pixels apps from market with no success.
Due to certain reasons cannot give the device to repair service, so, need to try to fix that by myself.
OS version is 4.3, if that matters.
Any help will be highly appreciated.
Will attach the screenshot. The line in the middle. Have few of them already. Background is green, to make it more visible.
Thanks!

Looks more like heat damage to the screen adhesive than a software/electronic defect, to me. I'm just guessing here, but could it have been left in a spot where a beam of focused light could burn the screen? Mine has a few little defects on the screen from where a water bottle on a window ledge focused the sunlight onto a point on the screen.
factory reset.
Flash stock rom and see .
Thanks for replies guys,
One more thing I probably should mention,
The line on the attached pic is maximized, the real lines are quite small, like 3-5mm length. Really small. But anyway visible...
Jaitsu,
Hmm tried to recall but don't think something like that happened. Sometimes I use my phone as GPS when riding bike, means it's outside under the sun (but not a focused light or something), max. 1 hour per time. Could that be reason?
Also, did you find any way to fix that, by yourself?
I read about several ways to fix screen issues, including leaving phone without battery for some time, or even placing it into the freezer. Tried battery method yesterday with no result, but kind of worry about the freezer...
JJEgan
Yes factory reset is a common advice but you really think it might help? Looks like a hardware issue to me. Can a software glitch damage the display? Also, lines are everywhere on the screen, not like one certain place.
Will give it a try if nothing else found, just, sounds uncommon...
Agree probably hardware but a factory reset rules out firmware .
Thats the first step for a service tech sheet .

DVP11 - Any ideas what's going on with this screen?

I know the odds of anyone even seeing this thread are probably slim, but oh well, worth a shot I guess. We got this DVP 11 (5130 model) a few months ago from a customer who needed a password removed and wanted to upgrade to Win10. No problem (well, one problem, but I'll deal with that later...)
Anyway, about a week later the customer brought it back, saying that "the screen's all white." He said he didn't know exactly *what* all he'd done to it, but that there was a better-than-likely chance that he had screwed something up by either dicking around with settings, or possibly by damaging something when he decided to open the tablet up and poke around inside for god knows what reason. Anyway, you can see the result in the pics below. My initial thought was simply that he'd damaged the video cable, as I'd seen a similar sort of thing before where that was the culprit, but it looks fine and a new replacement cable didn't solve the problem either. Anyway, it got sat aside and the guy never came back to claim it. I forgot we even had it until stumbling across it again the other night, but alas, I'm still stumped. I certainly don't *think* this is a software-related issue - HDMI output is fine - but I guess weirder things have happened. Is there some kind of backlight controller that's gone out? I can't seem to find any other examples of this problem, so it seems like a freak occurrence if so. Another unusual thing is that the "white" effect kinda lessens the longer it's on, as you can see in the pics - almost reminds me of an old CRT TV that needed to "warm up" first. (The pics make it look less noticeable than it actually is though - it never entirely goes away and is still more of a visual hinderance than it appears to be. The last pics were taken approx. 2-3 hours after the first ones.)
Any ideas what's going on?
