[Q] Desk clocks and Amoleds. - Galaxy Note II Q&A, Help & Troubleshooting

Is it safe to use the phone as a desk clock while charging at night? Ive read somewhere that amoled screens have screen burn-ins or something like that.an answer to this long sought after question would be much appreciated =) im sure alot of people would wanna know this.

Images don't really "burn" on amoled screens. LED's just will slowly get darker when they'r turned on.
"Normal" LED's, which aren't built as part of a display have a lifetime of about 70,000h.
That means that they will only have 70% of the starting-brigthness after that period of time.
I don't know the values of whole displays but you could definitely see some pixels, which are small LED's, glow less bright if they where turned on much longer then others
while watching a white picture.
This process may take a long time but i wouldn't let the screen turned on the whole night.

It should be fine and you don't need to worry about burn in effects with desk clock as the time display is constantly changing location on the screen. You would worry only if the display remains static for long periods of time.

[Q] Keepin phone screen on for long periods of time

Would it be bad to keep my phone screen on for long periods of time? For example if I wanted to use it as a clock next to my bed. Would it have any impact on the screen if it was on all night? I have the HTC Surround.
i think it probably would, the image may burn into the display and remain there
is there a way to leave the screen on all night? I thought there was no way to disable the auto off feature, just a way to change how long it takes to turn off.
i don't think so. it will not harm your screen. no digit will never stay the same for more than a couple of hours. As the previous post says, there may not be a way to keep it on anyway.
I've had a lot of phones that keep the screen on when the phone is plugged in. So that may mean all night...and no screen burn has ever happened. If you can get it stay on, you'll be fine

Unless you are using AM/PM clock format - M stays at the same place.
On the side note, I know AMOLED's are susceptible to burn-in, but I thought LCD tech had advanced to eliminate screen burn-in issues.
Never had a problem with LCD's - phone screen was left on every night on my TP2 whilst charging for the past 15 months with no ill-effect. Same on my Sony Ericsson C905.

[Q] Severe Screen Burn-in

My phone has really, really severe burn in. Basically I leave it on the clock app for like 20 minutes and the screen is burned in for maybe 5 minutes after i do something else. Also, sometimes I have it set to "Never turn display off while charging" when I test out my apps, but forget it and let it sit on the lockscreen for maybe 2 hours, and the residue remains for maybe 20 minutes. Is this abnormal, or does everyone have this? My phone is SLCD.
What is the residual effect that you're experiencing? Is it noticeable when you turn the screen off or when you navigate away from the burned in screen? I haven't heard of that but I suppose if the screen is left on for the whole time it's charging I could see that happening. Hasn't ever happened to me but I don't leave my screen on for that long. I wonder if the screen type makes a difference..

Sounds like an SLCD problem. I leave my AMOLED on desk clock over night, no burning.

Well, once I left it overnight, and it stuck there even on the lock screen. For example, I got a new notification, moving everything else to the right, and there was burn in of the previous icon. Also, the time was blurred (it was like 7:58, and you could see the digits 1 - 7 on the right number).

I read somewhere that only AMOLEDs could burn in. Weird, maybe that's wrong.
At least I can use my phone outdoors

I've never heard of OLED's having burn in :-/
I can use mine outdoors >_> just gotta turn the brightness on max
I leave mine on the clock app overnight every night and never had a problem, but then again, the clock bounces around like a screen saver, I'm assuming for exactly that reason.

AMOLED Incredible owner here, and I've left it on desk clock when I sleep, no burn in. I also use it on my desk at work as a clock, and I've been doing this for almost a year...
LCD does burn in. This is a problem in TV's where you can see channel logos getting burned in. Also, I can use my phone outside too Just gotta crank the brightness, that's all.
I can confirm that amoleds are able to burn in. The last replacement I got from vzw had the time burned in at the top and it was the first thing I noticed when I powered it on to the white "incredible" screen.

[Q] Just got my nexus, the screen dimming is annoying. help please.

I just got my Galaxy nexus (an hour ago), and I'm getting around using it pretty well except for one thing which is annoying me big time.
The screen seems to dim or change its color balance when viewing certain things. Whites are usually dimmed at most times, but when I view other things, the dimness goes away and whites become very radiant.
It seems like the phone is adjusting automatically to things on the screen for the sake of energy saving. How do i disable this!?
Yes, I have my Brightness on manual and set to full. That is not the issue.
okay wow this is getting annoying... Two more issues:
1-The thing won't transfer files while im using windows 7 "the device has either stopped responding or has been disconnected". When using OSX Lion, it isn't even detected.
2-There is chinese text here and there no matter what I do for language settings.
This is my first android phone ever, and I'm not liking the experience so far...
Look, I've tried searching for these two issues, and I did not find any threads with them resolved. Maybe I'm computer illiterate. Maybe I have a very low IQ, but can you just help me resolve these issues IF you know how to resolve them without just going into my thread and be like "Oh look, another noob", and proceed with leaving?
PS: I AM A NOOB.
Protip 1. Read up on amoled technology a little. And then read some of the issues some phones like galaxy s2 had. Your dimming is normal. It sounds like you're just more sensitive to it.
Protip 2. Download the appropriate drivers. In device manager, you want it to say android adb interface when you're phone is plugged in.
Protip 3. Take a chill pill. It is okay to be a noob. It happens. Your attitude comes off as annoying or you're freaking out over nothing. Solving problems take time and we are not sorry xda can solve them instantly for you. Patience, amigo.
My grandma beat me down and took my nexus. Sent from a jitterbug with beats by dre.
You might try turning of Auto Brightness and set it somewhere you feel comfortable... I just decided when I got this phone that I'd make myself get used to the adjustments and it's worked out well.
IMHO the adjustments going from white to black are less noticeable on 4.0.3
As far as the dimming, you have Auto Brightness on. Go to settings, screen and set the brightness to something else.

samsung drivers
for the drivers use this post
http://forum.xda-developers.com/showthread.php?p=20311264
PDAnet installs the drivers for you nice and easy, then you can remove from your phone and pc and the drivers will stay behind.
at this time there is no way to disable the screen dimming function. samsung's other phones have this feature as well, with an option to disable it in settings. its a power saving feature. for whatever reason google did not give any option to turn this on or off. so for now we have to wait if maybe a ROM can disable it.
For OSX you need to download Android file transfer for it to be seen.

Thank you everyone ...Sorry for the attitude earlier.
It seems like I got one of the GNexus phones which have a really good screen (The colors are just mind blowing), its only the dimming thing which is getting in the way. Also, I've tried to update to 4.0.3 and checked out the developer's section of the GNexus forum, but the steps are kind of overwhelming and I'm having my final exams at university right now, so I'll have to wait for a week to just sit back and read everything slowly and correctly.
One more thing, is there a download link to the official 4.0.3 mod ? It seems like everyone here prefers modded images one way or another.
lol. the dimming you are referring to is probably from current draw or a trait inherent to amoled. some people have mentioned they notice "dimming" like on white background browser and you pop up your keyboard. the white will get dimmer or yellower, or black more grayish. this is what you're talking about?

Its the opposite. When you draw the keyboard out, the whites get brighter and stronger. I don't have yellowing on my phone (thank god), but I do have dimming.
top make it simple:
The more the blacks = The brighter/stronger the whites.
Clearly a voltage issue for power consumption's sake. As the phone physically switches of diodes to achieve true blacks, more energy flows to lit diodes and they in turn become brighter.
Isn't there some sort of tweak deep enough to give full power to all diodes at all times regardless of what's on the screen (Full power even if the entire screen is white) ?
Firstly, welcome to Android. Once you get used to it you'll love it. I gave the same problem Windows 7 sometimes usually large video files and need to say that the adb drivers are not required to transfer files to the phone - I don't have them installed and I can still transfer data.
I have to say this is my first amoled device and I haven't noticed any dimming unless I have auto brightness on of course which I understand you don't.

ah yes. you're correct. i had it backwards.
I have the same issue with transferring large amounts of data using Windows 7. Looking for a fix too.
Investing the time to learn how to setup the SDK and using ADB will be well worth it.

Out of the three results I found searching for this topic, I'm glad I checked this thread.
The exact thing I was wondering was:
Is there any way to disable the screen from getting brighter when my keyboard comes up on the screen?
From reading your response, it seems that the screen getting brighter is a result of the design of the screen, suggesting that there is no way to stop it from happening. The only thing I've been able to do to make the screen remain at the brightness I set it is to change the theme of my keyboard to a brighter or lighter color based theme.
I'm using Swiftkey with the Neon keyboard, it looks great and I love it!
I had a Samsung Vibrant previously to the Galaxy Nexus, and there indeed was a "Power Saving Option" in the settings and if I remember correctly that stopped the screen from getting brighter with the keyboard on screen. Has any fix / ability to change this on a stock Galaxy Nexus running JB been found? It's just barely annoying enough for me to notice it, plus I'm a stickler for more battery life and I can feel my battery dying the brighter the screen gets. ( I know this last part may be a mental thing, but still. Haha. )

Burn-in: does anyone have it yet? How paranoid should we be?

Has anyone noticed any burn-in problems yet? I've seen reports of the problem for some other watches (LG), but so far nothing specific here for the Huawei.
It's so far so good for me, but I've been extremely nervous about this issue. I avoid faces with things like thick tic marks or logos in ambient mode. I know about Wear's built-in "protection," but I don't have a lot of confidence in it. Am I being unreasonable?

I had the GWR and didn't have any issues with that at all. That said I turn the screen off at night during charging so maybe that helps. I'll keep an eye on the Huawei, but I'm hopeful that it will be fine.

I had the GWR for almost a year too. Always used watchfaces that are 'always on' (so no dimmed mode without background) and always had the charging animation on by night. Never experienced any burn-in.
I just powered mine on for the first time last night. I played with it for a few hours, then put it in the charger for the night and this morning it has burn-in!! How could it happen so fast??

That deserves an RMA and you deserve a new replacement watch.
I sometimes get lag on mine, im not sure if it's actual lag or whether im doing something wrong but as someone mentioned if the watch went full brightness and is charging then the heat might have done it?
I returned it yesterday to best buy. Lucky me though. . they had cyber Monday deals and it was on sale for $50 less! !
I noticed that when the minute hands on mine move (ie every minute) that the whole screen kind of does a refresh. I'm using a custom watch face called InstaWeather, and in the settings there's an option to help with screen burn. I wonder if this is it? So every minute, every pixel would have been off/on or on/off?

yes, this is an android wear burn in protection buy moving a few pixels in all directions, works very good if you don't have large objects in the ambient mode, and won't help much if you have.

In my opinion, yes, you are being overly worried. First the technologies itself has improved and we see less burn-in even when we set screens on to test such a thing. Second, the ability to move(write) a watch face or screen is not some huge leap, in fact it's really super easy to add to an OS to simply move the screen pin outs when in any long display mode. Beyond all that, app makers, watch face builders, now have the old data and make sure they write to avoid any long same display visual mode.
Easy to add to an app, when write same display, write 2 pixels, change.
Then after all that we have face on mode and ambient mode, which in my daily use changes my watch face enough that I would never get burn in. Agree that I am a heavy user of the watch, I tend to have to change twice a day. Perhaps someone that used the watch much less would have more of a concern?
I have the same problem

Wrong. You must not understand what screen burn in is. No new technology has come out that will stop screen burn in. The software that moves the pixels over only works if the object is 1 pixel wide other wise it doesn't work screen burn in will still happen. And they do not have it where the same pixels won't be used otherwise in ambient mode it would jump around not wiggle.

Reset the watch. It may not be burn in. I saw a bug like this from using too high Def of an image on a watch face. It got stuck in the cache even after I changed watch faces. I reset the watch and haven't had any issues since

Fare enough, just my opinion, & you have yours. Too bad you had to start by saying wrong.
Samsung has made changes to light output and color to reduce burn in, and we all know there is some type of display movement now to also reduce burn in, so it's odd you claim there has been nothing.
Anywho, I don't get burn in so yea, maybe with your attitude if you do, you deserve it?

I'm not going to start it by saying you're right, am I? Samsung didn't make changes to anything in light output the only thing that's changed is adaptive screen color which is meant to adapt the screen contrast to show what's on screen in the best possible colors. There is no new technology that will stop burn in. You must not have understood me. The image wiggle is a software attempt to stop screen burn in from happening but it won't stop it just slow it down. Screen burn in will continue to be a thing until the panels we use change technology. I didn't say that nothing has been made to prevent it.
And if you sense attitude in a straightforward response that's on you. I'll let karma deal with that comment. I personally don't get screen burn in and I've had a SAMOLED device since the Samsung Epic. I just understand how to prevent it. But just because I've never had it I won't tell people that they're overly concerned about screen burn in.

ambient burn in

Hey guys
silly question, but if you leave the ambient clock on, will this cause burn in? I use my phone as an alarm when I go to bed
I did take teh Nov update, but no way to confirm if the burn issue is fixed.
TIA
have you seen any reports of burn in from the ambient display? NO. So there's your answer. If this was happening it would be blown out of proportion just like everything else with the display.
You mean the always on dim display thing? They said it moves around to avoid that.
Well the pixels displaying your time and notifications are on while the rest of the screen is off. There's the possibility for uneven wear, but I doubt it would ever show or you would never notice it.

It still does wear pixels unevenly but the amount of time it would need with it being moved every minute in a zigzag pattern makes it pass the burn-in concern. I'd say if you use your phone normally you'd see something show up in 1-2 years. However, if you leave your phone under a bright light for long periods of time you might want to disable always on display feature.
