Please, any input is useful. ):
I just bought a nexus one the other day, and i think I was scammed. THe power button works fine, but occasionally, the screen would get super dim. It doesn't black out because I can faintly see all of the icons and menus, and I can tap them. ALso, its not automatic brightness, because its horribly horribly hard to see. Pulling the battery (sometimes) fixes this problem.
I'm currently running Kang-o-rama with SP2.
Has this ever happened to anyone? If so, how did you fix it?
It does sound its the auto brightness. If you're outside and its dims it is very hard to see. You the default android power widget to test it. It has brightness toggle on it. Full /auto/dim/ and basically the middle.
I'll take a picture of it once my dad comes home, but I tested it last night if it was autobrightness.
I waited for it to dim, then went into settings, disabled autobrightness, and put the brightness all the way up. It was still super dim, and didn't return to normal until I pulled the battery.
I would look for support in the thread for that rom. Or flash another rom. Sounds like it is just a bug in your rom.
I just installed a Miui rom hoping it'll fix it (cause I was using cm7 based roms) and it worked for a while.
Now it began to Flicker and finally turned off. It'll ring when phones call it but nothing will show on the screen. I'll pull the battery but this time nothing shows up (though it vibrates indicating it turns on).
I know this is a hardware problem now, do you guys know what part it is?
Please, any input is appreciated.

Hello guys I wrote a guide that will help you improve your battery life because screen is the most thing that uses battery, here is a solution for all that, don't forget that the screen sensor for auto brightness is also taking lot of power.
enjoy
The first app is useful for Galaxy Nexus only.
The second application is useful for both.
"The downside is that an IPS-LCD may consume more power than a TFT-LCD."

The N7 has a backlit IPS screen, how would adding a filter to make the screen darker save any power? An an amoled screen sure, although I never noticed much power savings with my Epic 4G.

The filter dims the screen because the Amoled is too bright even with lowest brightness, and the filter darken that's right but that also means lower brightness from lamps, the filter is different then lowering the brightness on system.

Doesn't matter, the leds are still outputting the same amount of energy, you're just making the screen darker. Easier on your eyes maybe, not the battery.

the N7 doesn't have an amoled screen.
and it doesn't have amoled backlight either.....

You are right, read up I fixed the post.
No no no just no. Again this NOT a amoled screen. Blacks do not shut the pixels off. Its backlit LCD. The the light is always on when the screen is on. Hell it takes more enegery for a LCD to produce blacks over whites.

Read again, I said the second app is useful which is auto brightness.
https://play.google.com/store/apps/details?id=com.nnevod.loggraph&feature=search_result
This app lets you setup autobrightness based on light sensor values. Gives you the option of using a filter or actual backlight levels. Can let you use level lower than android normally allows.
Why would you need to save battery? The battery life is amazing

Does it really work and save more battery juice?
+1
Replacing auto brightness with a manual alternative that's properly managed will save some battery. Check out display brightness by BigRubberPepper.
It will allow an invisible or barely visible and customizable widget to put a slider st the very edge of the screen wherever you so choose to control the brightness in 1% increments.

But running that widget all the time in the background might consume same, if not more battery life and negate any additional advantage?

Elixir Widgets
I'm using Elixir 2 Widgets for system status reporting and options like when to run GPS/BT/autorotate, in fact I have 32 small panel items up in one widget on one of my screens. On my primary page I also have a 1x1 widget for brightness set to 8%, 23%, 65% for the primary environments i am in.
I've never seen the widget using as much as 1% of my battery life (Ran battery dry over 2d and just short of 7h screen time, almost the entire 2d had it hooked up running Google play to my computer speakers)
I'd say that using a homepage, 1touch widget has had a big part in this. Even compared to https://play.google.com/store/apps/details?id=com.nnevod.loggraph&feature=search_result which really took a while to register the change in light (as much as 45 seconds in some cases) and would reduce screen brightness in bright enviornments when my head was between light source and Nexus.
The screen filter app, while small in size (57kb) and minimal memory footprint (8.5MB), does affect the screen smoothness. Transitions between screens, menus and other settings seemed affected.
Will try it out for a couple of days and post any additional impressions.

none of these actually lower your brightness MORE than the minimum. And screen filters are just a black overlay that goes transparent to fake dimming.

Hello everybody, I have the following "visual effect". It happens roughly 50% of the times the display switches off. It doesn't matter if it is by it self, by the power button or by a software button. In the very moment when the display switches off, a greenish dot in the center of the display flicks for a split second, along with a same color vertical line trough the whole screen. Obviously it is not supposed to be this way Beside this issue, there is no other problems with the display or the phone( for now). What do you think about this? Thanks in advance
Sounds like a screen off CRT effect, check you tube to see if that is your problem
Isn't the CRT effect a horizontal white line ending up in a dot?
I genuinely think the OP's screen may be defective...
Sent from my GT-N7000 using xda app-developers app
do a lcd test and check if all pixels are working ok
Unfortunately it is not a CRT effect, although it looks a bit like it. The difference is, that the line and the dot( little spot) appear simultaneously for a fraction of a second. In a daylight it is hard to see it, even more it happens just 50% of the times, but not every other time. Its somewhat random.
The *#0*# test do not show much. No dead pixels. On blue you cant see anything, on green and red I think I see a little bit darker spot in the center of the screen( where the dot/spot appears), but there are such darker sports and elsewhere on the screen.
BTW, I noticed recently, that when the screens dims a bit shortly before switching off, this dimming happens not so smooth. How should I say it... it happens on a several steps, although the whole thing is done in less then a second, it is not so fluid. Is it supposed to be this way?
Thanks for your help guys
have u tried flashing a different rom stock
I am on the latest German stock 4.0.4, tried several others, including 2.3.6. .Currently with Hydra kernel. No difference whatsoever. I think the auto-brightness doesnt work so good. When set on fixed value it dims more fluidly.
if u on stock rom and not rooted then take it to a service center
I just got my Asus tf701t and, while first using it, the home and back buttons did not work in portrait mode and the screen would change brightness at varying time intervals (usually a few seconds) when the brightness was set very low. an update to 4.3 cured the back and home button issue but the screen still can't stay at one brightness level when I set it to very dim. It's not changing dramatically, more like a few percent, but enough to be distracting.
The odd part is that the dimming/brightening issue almost seems application dependent. It occurs far more often in the home screen or skout but almost never when playing shadowgun dead zone or when using naked browser.
Does anyone else have similar issues?
The only posts about flickering on other people's tf701t seem to be related to power saving and I need to know if this needs to be exchanged or if this is a common problem.

I don't have the flickering when not on auto and lowest setting.
However some apps can dimm the screen while loading.
On the TF700 the stock browser did that when loading a page but on the TF701 the brightness doesn't do that.
You have an ambient light sensor built into the device. It adjusts the brightness based on the lighting in your environment. It can't be turned off either.

It can't be turned off? So when you turn on automatic brightness it just changes the brightness more drastically? This doesn't sound right.
Based on the other poster's response, I think I need to return this unit. The screen dimming/brightening happens to often and randomly to be part of my apps and I even noticed, in some apps, that just touching the screen causes a brightness change.
Even if this is by design, it is far too distracting.

My 701 is doing this as well. Turned off auto brightness, turned off power saver, rebooted. When it comes back up the device acts like auto brightness is on, with screen brightness fluctuaating randomly. Turning power saver on and off again seems to solve it, but that behavior is very annoying - it's why I turn auto brightness off in the first place.
US SKU running 4.3 installed via ota, no root or unlock or anything - straight stock. Its also my second device, my original had a bad cable and wouldn't charge. Serial number ends in 072259.

I also tried turning power saver mode on and off and for me it seemed to improve the situation but not eliminate it. I am going to return the tablet and wait for the nexus 10.
Ugh, mine has been doing this, too. Can't believe there isn't a setting somewhere...
Mine is doing the same thing... glad that it's not just me, but this flickering is very annoying
Driving me nuts
I'm having the same problem and it's driving me nuts!
I'm quite convinced it's a software "feature" but currently there seems to be no way to turn it off?
It's one of those "Adjust brightness of the screen based on content" or "Changing LCD refresh rate and colors for power saving" but sadly it does it the wrong way around (This has been going on for a while now, manufacturers don't really get it). When there is a lot of bright content the brightness will rise and when there is mostly a dark screen it will fall.
Of course, this should happen exactly the other way around. When there is a lot of bright/white on my screen it should lower and when there is mostly black it should become brighter thus giving you more contrast but keeping the overall lux that comes off your screen the same...... My Intel graphics notebook does this too and it's very irritating. There they do it by manipulating the LCD screen and lowering the refresh rate and other tricks to save battery. First thing I turned off.
However way it goes though, you should be able to turn it off!

I'm having the same issue. I think it's the smart dimmer option Asus have used before but they forgot to include it in the Asus customised options. I'll have a dig through the ROM to see where it is stored.
I'm having this problem as well.
I have my brightness set to about 80%, Auto-Brightness Off, Power Save Off.
It is very annoying when reading magazines that have a lot of white background. My screen will be stable for minutes then, often on a touch, will change the screen brightness, seemingly by 5-20%.
I was just getting ready to return it, and thought I would check here to see of anyone else has this problem. Has any actually called Asus with this complaint? I would be interested to know if they see this as a hardware defect, software bug, or working as designed.
PS - I just placed a technical support request about this on the Asus Website. Here is my problem description:
Even with automatic brightness & power saving turned off, the brightness of the screen will change over time, often seemingly in response to a touch. (Reading Mode is Off as well.)
The period between changes can vary from several minutes to 30 seconds. It happens both while docked and undocked. It happens with apps and just at the launcher.
The amount of brightness change is 5-20% and it will often seem to step through some values before it stops at a particular one.
Given how fantastic looking the screen is, this unwanted fluctuation is particularly annoying.
I also own a TF201 and have not experienced this problem on that product.

I suspect this is the same "smart dimming" feature that the 700 had.

There seems to be no way to disable this. Some believe it's the light sensor, but I've taped over mine with black electrical tape and tested and I don't see any difference in the behavior. Check our my Youtube video if you are a user who doesn't see the issue (look for threads in this same XDA forum).
I've finally been able to get someone at Asus to look into this and it's been sent to TW for review. I haven't heard anything back yet. I strongly recommend that other people who are annoyed by this (I find it tremendously distracting) to search on "asus escalation" which will bring up a special mailbox. Here is the link (although I do not know if the link will work for you). This should get looked at by someone with at least some ability beyond reading a script. If enough people do this, I think that they will fix it. Since you can temporarily override it by toggling smart saver on/off, it has to be fixable by software.

Ok so every phone ive had i turn off the auto brightness and crack it all the way up.
Then when im using the phone and i haven't touched anything the screen will go from 100% brightness to 50% and then a few seconds later (if i don't touch the screen) the screen turns off.
Well ive noticed this only happens sometimes. (uselly when im at work it works) But 90% of the time, ill be using the phone then after some inactivity the screen dims from 100% to like 98% if your not looking for it you wouldn't even notice. Then a few seconds later turns all the way off.
I have smart stare or w/e it is turned off.

Noticed the same problem here. With auto brightness on dimming works correctly, but I never find auto brightness does what I want, so I usually don't use it. Very annoying problem! Hopefully Samsung fixes this issue soon!
I'm facing the same issue. My phone goes to screen off mode without dimming, which is very annoying. Otherwise, the phone is pretty good.
