Will leaving my screen on for 8+ hours each night be bad for it?

I want to use smart alarm, but don't like the idea of leaving my screen on all night. Is there anyway to get around this requirement, or another app that i just don't know about?

Klaxon does not require you to leave the screen on as well as the stock (Sense) alarm.

Nevermind...

Ummm haha confused now

I've been using mine as an alarm clock with the screen on and the backlight on low every night for about 3 months now. I've noticed no ill effects. I was under the impression that LCD screens are immune to "burn-in" and the LED backlight should have a really long life, so I haven't been too worried about it.

Huh? I use mine as an alarm clock but it doesn't require me to leave screen on.

The smart alarm requires the screen to be on because of a bug in android that turns the accelerometer off when the screen goes off. It is one of those 'smart' alarms that is supposes to sense the sleep cycle.
I think I will use it with the screen on for a while. I want to see of these alarms really work.

leaving the screen on is not a problem. the evo does not have an AMOLED screen, it uses LCD. the O in AMOLED is subject to deterioration and will get burn in the more the screen is used and the brighter the screen is.
LCD does not suffer this. go ahead and leave the screen on.

Thanks everyone!

[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.

I take it you missed the part where the op said his brightness is set on manual?

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. )

Screen flicker?

I guess flickering is the best way to describe it. On certain gradients and colors, the screen will flicker and have some distortion. Is this normal with the phone or is there an issue with the screen?

Turn down the screen brightness a bit

Even at low brightness it still kinda looks like this. I feel like there's something messed up with the screen...

Are you using a kernel with voodoo color support? If you are, that could be the culprit. I'd install the Voodoo color/sound app and try changing a few of the settings to see if that changes anything

I may have a similar issue on my Epic, though much worse... Check and see if you get the same effects in download mode or nandroid whatever...
My screen started with a blueish flicker and then got worse and worse over the past month, now the whole screen is covered by a translucent blue, I can barely make out whats going on behind it. Though the phone still functions, the display is trashed. Perhaps a loose connection or broken flex cable.

Have you checked your battery? My mom has this phone and had the same problem... I took her battery out and spun it on a table and you could see how warped and swollen it was. These batteries can warp and explode, causing damage to the phone and bodily harm. If your battery is misshapen, take it into Sprint- they will have to swap it out! I got my mom a new battery from them, and her screen is fine now- no flicker. Because it was intermittent (occurring seemingly at random), I was able to rule out being a screen problem. Her screen is fine, it was the battery.
I'm not saying the battery is definitely your problem here, but it is a known problem with the design of the battery/phone, and can cause a lot of damage if your battery IS bad and it is not replaced. Check your battery, it very well may resolve this issue you're having with screen flicker. Otherwise, I don't know

Thanks, I was wondering why my screen had random blotches of yellow flickering, so I swapped my battery, and voilà it's gone. All I need to do now is replace both of them.

Notification light on nexus 7

Hi all I have just bought the new nexus 7 and I love it. One problem is I have never seen the notification light work yet. I have checked in settings and it's ticked.. When does it flash? Is it every time you get a notification from eg Facebook etc,? I'm worried it's not working.

The light is usually associated with notifications, yes. Usually this is configurable in the apps responsible for the notifications.

I thought the same when I got mine but it was flashing during a notification a while back so at least it works but rare.

Mine triggers on e-mails, so I see it a lot!

Does work thanks sent myself an Email

I use LightFlow and configured the light to fade in and out with almost no period of time where the light is off. It looks as if the light is "breathing", and is much more noticeable than the 10 second delay between flashes that the stock light is. Give it a shot.

So far, I've only seen it light with email. General notifications don't seem to trigger it.

My first Nexus 7 (2013) had a completely broken notification light. No matter what I did, I couldn't get it to light up. (I ran testing programs, Light Flow, sent myself emails, etc). Exchanged it at Best Buy and the new one worked immediately. So just know that there are some defective notification LEDs out there.

There's a whole slew of less common issues that IMO if it bothers you, you should get an exchange, but if not, just live with it.
LED doesn't work
NFC doesn't work
Bluetooth doesn't work
Qi wireless charging doesn't work
dust under screen
light bleed
offwhite screens
dead/stuck pixels
mushy Power/Volume buttons
creaky edges
back cover comes off easily
screen separating from tablet
battery charger not recognized even though it is charging
microphone doesn't work
one speaker has no sound
charger makes buzzing noise
camera blurry
--
spasdic multi-touch
touchscreen dead-spots
camera crashes tablet
hardware related random reboots (not the same as software-related reboots)
--
The last 4 can sometimes be mitigated in software so try fixes first.
Many of these issues are rare. Some are more common. I think a lot of people don't even notice or just live with it because it really doesn't bother them that much or they don't even use the feature.

What settings did you use to do this? Sounds interesting.

Hmm...it sounds like my LED light took a dump on me then. I've had my Nexus 7 2013 for about a month. It used to notify me for emails...now nothing. And yes it does bother me.
