Yeah, I get a slight flicker, but like as if the auto brightness is still on but not as strong.

I turn auto brightness off, but I know what you mean.
These are actual lines

Mine looks like the auto brightness gets a bit jittery. Usually when on the net but I've had it in a few other places. It makes it look like the processor is struggling to handle what ever is going on, it isn't, but it gives that impression.
Maybe the transition between brightness levels is set to too big an increment so it appears to jump between levels instead of smoothly fading.

Turn off auto brightness.
I didn't notice it until I sat under a certain light in my house. I guess the luminance in the room sits between two thresholds and causes it to madly flick between them. It looks like a bug which will hopefully get fixed!

Nope, as stated its not auto brightness, I have it turned off.
I've noticed its not on every app. Farm invasion USA it will only have the lines flickering when the character respawns. Browsing the Web that often, watching a movie it doesn't do it at all.

The app I mentioned I think it may be normal upon respawn, I'll test it on my SXS
Still, it flickers on chrome, and it's also done it just while in the dialer

I've only noticed flickering when I had auto brightness turned on. I've been using my phone and N7 exclusively for the last two weeks as I had no access to a computer, so it got enough viewing!
With auto brightness on, in some lighting situations I am able to reproduce the flickering by angling the phone so it borders on the threshold it changes to the next level.
I've turned auto brightness off, and have not noticed any flickering while using Chrome/Tapatalk/Spotify/WhatsApp/Talk/SMS etc etc.
Only thing that bugs me so far is the noisy vibrate, bugged me so much I had to turn off haptic feedback.

[Q] Light Sensor Not Working?

Someone correct me if I am wrong but shouldn't enabling the option of "Automatic brightness adjustment" under the brightness menu in sounds and display enable the light sensor to adjust the brightness of the LCD based on ambient lighting? I notice no difference with my brightness and it is always one static level. I've tried putting it up to different lights, taking it outside, etc and it doesn't automatically adjust. I couldn't find anything in a search for this... does anyone else have this problem?
I have this problem as well. What firmware are you running and do you have any mods or sre or anything?

I'm just running stock firmware rooted, I'm going to flash to some kind of rom eventually but just haven't had the time
Are there any roms that this option is confirmed working?
Mine is stock and seems to work just fine. It changes brightness as I move through the office between dark reading rooms and bright conference rooms.
I'm not a big fan of that feature in any of my phones. I prefer to have a constant bright screen, but I haven't bothered turning it off yet for some reason.
Weird how mine doesn't work.. I just waste battery life while I am in the office with the phone and wish it would auto adjust. I'm trying the beautiful brightness widget but I find it tedious to have to micro manage my brightness before going outside
Have you installed any type of screen protector that requires the use of water to apply? I'm wondering if that's what happened to mine.

Auto brightness doesn't seem to be working too well in JH7 for me. Keeps the brightness all the way down in my lit up room. Worked best on the original JF6.
I have seen my screen change brightness a few times with the automatic setting, but I generally keep it on the lowest brightness to save battery. I'm running the stock firmware.
My biggest problem with the auto brightness is that the dynamic range isn't wide enough. Even in direct sunlight, it doesn't bump up to maximum brightness. The high should be higher, and the low should be loooower.

I noticed the same...no change in brightness when "auto" is selected. From day 1. I keep my brightness pretty low to save battery life, so it wasn't a deal breaker. Would be nice if it worked though.

[Q] Screen too bright?

Is there a way to dim the screen a bit more via a mod or app? I love this thing but it seems too bright even on the lowest setting when reading in a dim or dark room. If you read via the kindle app it seems to dim a bit more than the stock lowest setting and is quite comfortable in a dim/ dark room.
Any tips?
There is an app in the market called AdjBrightness. I can't remember if you have to be rooted, but it works great for turning the backlight below the lowest setting.
I think the short answer is, if you're on "stock", no. If you're rooted, yes. Via multiple methods. Lots of brightness-control apps let you go lower (such as mentioned above), and I have two book readers (Aldiko and Cool Reader) which will both dim right down to off and every step between.
Thanks for the input. I am rooted, and was hoping for some suggestions like the ones provided. These should help, esp since i don't have many lights around the apt. Appreciate the help.
Try screenfilter from the Market. It will add a dimming shade. I use it when I read in dim settings
Sent from my LogicPD Zoom2 using XDA App
I just started using AdjBrightness and it's much better than the screen filter apps I've tried. With those, you still have the bright light shining in your eyes, only with the whiter parts of the screen turned gray. That helped but not a lot. AdjBrightness actually dims the backlight well below the stock minimum of 10. I set mine to 4 when reading in the dark and it's quite comfortable. 4 seems to be the NC's lower limit, as 3 or less caused my screen to shut off and freak out when I would try to turn it back on.

+1.
Also, warning: if you set AdjBrightness too low (3 or less) and have it set not to reset on startup you may not be able to see your screen even just to turn AdjBrightness back on!
Another little trick is to adjust the text and background color. I also found it to be too bright for reading before bed at night, but gray text on a black background solved that nicely. This works with both Aldiko and the stock reader

Thanks a lot! I could have needed that while my wife was using it to read at night in bed during her pregnancy But that was before I knew what the Nook Color could do besides ebooks!

Problems with autobrightness

If i set my screen to auto brightness it just flicks from lighter to darker every second if i sit near a window. Really annoying that the screen adjusts ALL the time.
Is there a way to fix this? Without rooting.

Screen Flickering On low light?

My screen flickers sometimes in the power saver mode n also when my brightness is set to about less than 40%. Should I be worried or it can be fixed in the software update? Anyone else with the same problem?

Can you check for me if changing to another keyboard solves this flicker? I too noticed this ever so slight flicker but only when using stock keyboard if I change over to Swiftkey then it doesn't happen for me. It looks like its the screen flickering but in actual fact it seems to be just the keyboard area of the screen.
Report back if it fixes the issue for you. If it does then obviously this is software and we needn't worry.
sprint htc one user here. stock not rooted.
ive seen this obvious abrupt dimming since day one (had since launch). i use swiftkey only and no other keyboard.
when the screen is not in use i still see the screen dim. it dims abruptly as opposed to a gradual dim. i chalked it up to software that may be included in an update.
does NOT do it ALL the time though....
Well I tried with SwiftKey it didn't work. It's not just the keyboard are that flickers. It's the whole screen like trying to adjust to a particular brightness. If the brightness is set to about 70% there is no flicker

Screen changing brightness when not on Auto and no power saving...

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.

Yep me too and as soon as I root I'm going to see if the same fix will turn it off
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.
