Just received my tf700t and updated to the new firmware. I noticed that when switching from any screen back to home screen and even throughout watching movies on my tablet, the screen brightness constantly adjusts even with automatic brightness turned off. Its pretty annoying esp. while watching movies. Is there a solution to this problem?
Can't say I have noticed that, and I've used it both with automatic brightness on and off. Maybe try a factory reset?

I noticed the same thing - I believe it's the LED backlight adjusting when you go from bright-to-dim and dim-to-bright screens. It is annoying though. I'm assuming that I'll just get used to it (I just got my TF700 yesterday)...

So your saying that taking off the auto and setting it to the brightest setting and it still adjusts by itself.

Yes, I have noticed it as well. Doesn't bother me, though -- I'd rather have the system tweak itself for brightness than just picking a brightness off-hand and sticking to it.
I've previously owned the tf101 and never had anything like this happen. I use my tf700t at about 30-40% ips, and it constantly adjusts. I haven't tried it at full brightness, but it still is weird that it would keep adjusting even throughout watching movies. It almost like 3 or 4 subtle brightness changes when going from say the apps screen back to the home menu (on default wallpaper). I went through all my settings and googled it without success, so I'm figuring that people either don't notice or just aren't bothered by it. It's driving me crazy though
I noticed this...and thought I was going crazy. Thanks for confirming it's not just me and yes it drives me nuts. Hopefully there comes out a way to stop it.
Auto brightness was way too dim for me. So I've disabled it and set the brightness myself.

What I'm talking about has nothing to do with auto brightness. When it's turned off, there seems to be some type of secondary auto brightness that you have no control over because it constantly adjusts when switching through certain apps/screens and playing movies. Look closely at the screen and you should see it. I'm glad I'm not alone as a few others have confirmed this discovery as well. I don't understand the point in setting your own brightness when the tablet will still adjust itself with auto shut off. I hope a fix of some sort will come soon.
I have not noticed any change in brightness levels with auto brightness turned off.
It reminds me a bit of the brightness/contrast adaptation my SGS2 does -- only there it can be toggled under the display settings, whereas on the TF700 you're just stuck with it.
I don't think that the screen is actually changing brightness - just that the backlight is adjusting as needed depending on how much bright/dim colors are on the screen...
What's strange is that if I enable auto-brightness (which works great in the bright office), that effect seems to go away... Very strange...
I'm assuming that it's a battery-saving thing, but I'm really not sure...

I actually watched this happen (without auto brightness on) without transitioning to a new screen while scrolling past a dark image on a light forum thread. I think it's a tegra 3 thing. I know I read about t3 dynamically adjusting the backlight during video playback and saving more energy in the process than the t3 soc itself consumes during playback.
I've been using mine on power save mode so far. I'm betting the brightness changes would be more fluid and less noticeable at higher speeds.
Read your user manuals. It discusses the feature in its entirety.:good:

So that's probably your answer,
You running on maximum power saving mode. What you expect?
You asking tablet to save all power it can, and that's exactly what's it's doing.
Of course there's a chance of defect, hardware it software. But that could only be tested on a group of other tablets using same settings, to try to recreate what you describing.

I've noticed the same, as well as a few other users, we actually had a (sub)thread about this a few days ago here.
This is in fact very similar (or equal) to dynamic contrast we all know from LCD screens. Unfortunately I do not know the solution, but setting the brightness to as low as I need in any given lighting conditions helps.

You were mistaken in thinking there was any complaint at all in that post.
I don't think it's been usable (auto-brightness) on any Android device I've owned. Typically, in a home setting, it simply sets the brightness to the lowest setting, which is way too dim. Why can't they implement a "customizable" auto-brightness so that it's actually usable???
Does anyone else have any better luck with Auto-brightness on Android devices??
Actually, I *do* have one Android device where it works properly - my HTC EVO V 4G.
Yes, I know there are apps in the Market but they always seems overly-complicated. I just want a simple brightness slider that can adjust the auto-brightness, like on iOS devices (was trying to avoid mentioning that, but it's the best way to describe what I'm looking for).
Anyone know of a way to customize the auto-brightness level without a 3rd party app?
Thanks for listening while I vent!

In the case of the TF700 I found that switching on the Super IPS+ while in auto brightness mode makes it usable. I totally agree with your point, adjustable would be nice. The TF700 is the worst I've seen. Even in fairly brightly lit rooms mine turns the brightness all the way down.
The only device I have been able to leave autobrightness on is with the Galaxy Nexus. However, I am noticing constant adjustments in brightness on the Infinity, even with autobrightness turned off. Are you guys experiencing the same thing?

Yeah, it's actually just the dynamic contrast adjusting the backlight levels depending on how much white is on the screen, etc... No way to avoid that yet...

I have purchased Lux and it does work, but I just wish it were as simple as a single slider to adjust the auto-brightness - Lux is overly complicated (in my opinion).... I've actually found it easier to just adjust the brightness manually when needed instead of trying to get Lux to do what I want it to do...

You must have better luck than I - I found myself having to constantly add new "levels" to make the brightness adjust properly for the current lighting - it was never as automatic as I had assumed it would be.... THen i had issues where certain apps wouldn't install anymore and had to enable a special option to let me install apps again, etc - again, just not as simple as I had hoped...
Maybe I'll give it another shot... Maybe it's better than it used to be...

Maybe your sensor is faulty?
Sometimes I have a glitch too but it is as randomly as the I/O so I thought/think it is related.

Man, my sensor must be on steroids. I'm going thru theze new threads and am wondering if I've got the same pad.. I went into my settings and changed to"auto" but still get good resolution contrast and readability. Sure, there is a small diff between the bedroom and the hammock, where I am right now wondering if I over did the 32 gig sdxd cards since i don't game. But really now, this is heaven and we want more???

My auto-brightness works great in bright envs. But at home in normal lighting, it sets the brightness all the way down (my TF101 did the same thing so I highly doubt it's a bad light sensor). It's un-usable. Of course, I want more - let me adjust it!
Sent from my ASUS Transformer Pad TF700T using Tapatalk 2
Lux and I bet there are other apps for this, has a debug mode that outputs what the sensor-api returns.
So get there or get such an app and try if the sensor readings are somewhat reasonable.
That method showed me my sensor has also a little problems with darker surroundings.
Sometimes it will get stuck at a low leven like 4 lux and not go down all the way to zero.

Hi guys,
So I just got my forth Infinity Everything seems to be OK this time so I can finally play with it There is one thing I didn't notice in the last three tabs, but it is because I have never used it in dark conditions so far. Anyway I just noticed that if my brigthness is set to 10-30% (no auto mode) and if I run some application with dark background (like Gallery, YouTube or some screens of Google Play) it is visible (but you need to pay attention) that screen gets dimmed a little and if I return to homescreen it is noticable that screen get's brighter after some time. I think it won''t be visible, but there is some little lag of adjusting the brightness. If I reduce the brightness maximally to the left it is not visible, also if I move it to >80% it is also not visible. If I run app with white background (like GMail or Internet) there is no such issue. Is it normal ? It is not big issue, but I'm praying I don't have to send it for replacement once again I checked it both on normal and balanced mode while running on battery. I have to check if there is difference if I'm plugged into AC power, but I don't have such issue on my HTC Sensation.
Sounds like the same issue I'm experiencing.

Hi CeeJayII,
Yes, your issue seems to be related, but is not the same. You wrote:

... for instance if browsing at 100% in only seems to drop to 85% when watching video. Is this normal? I've noticed the most difference when the brightness is set at 0%. I'll watch netflix then press the home button, the screen stays at video brightness (darker) for a second then restores back to the original setting.

In my case I can't tell how much it has dropped, because looking at the brigthness level in statusbar it seems to be the same, but it is still visible that the brightness has been reduced/increased. In my case it is definitely not reduced/increased by 15%, I would say it is something like 2-5%. Besides that in my case everything is OK if my brightess level is 0% or more than 80%. But in your case it seems to be similar, because you are watching netflix (dark background) and when you go to homescreen the brightness is restored. Maybe it is some power-saving method to prolonge our battery lifes ? Anyone else can confirm the issue ?
Well I may have overstated, when brightness is at zero there is quite a drop. The higher the brightness, the less noticeable it is. It doesn't change on the brightness slider for me either, just seems to dim a little. I think it is the same issue. I'm guessing it is normal.
OK, so it seems to be the same issue. Let's wait for other user to reply if they observe the same thing.
This sounds like the SmartDimmer (which is different than auto-brightness - it's kinda like dynamic contrast). You can disable it if you are rooted.

What's really strange is that I just picked up a Nexus 7 and the "SmartDimmer" is barely even noticeable on the Nexus 7, which is where that tweak originally came from (over in the Nexus 7 forums)!?
The issue is *way* more noticeable on the TF700 (I probably would have never even noticed the issue on the Nexus 7) - almost like there is some sort of bug in the TF700 firmware as it relates to the SmartDimmer. It drove me *crazy* on the TF700...
Anyway, it's well worth rooting to get rid of the constant flickering!
EDIT: By the way, the search function in the Tapatalk app is next to useless... Unless someone knows something that I don't - for example, is it even possible to limit the search to a particular forum/subforum in tapatalk?

That's strange, as they're both IPS and manufactured by ASUS (the Infinity with some added brightness if used), it'd be nice to compare the config files you mentioned in your posts on both devices, along with smartdimmer settings in the plaintext files.
Just a thought, but as there are more pixels on the Infinity - is it actually faster on the N7?

I've had mine for about a week, replacing a Prime (just for the hell of it, my Prime actually doesn't have any real problems).
Except for a couple of browser ANRs, and none in quite a few days, I have had none of those problems. It's really a solid tablet, and does improve upon the Prime in a few ways (we all know which ones by now, I'm sure). Tiny bit of screen movement on the bottom left, tiny bit of light bleed that I only ever notice when booting, but otherwise perfect.
Agree, every since I upgraded to JB and lost my root (like a noob) I have had better performance out of it. It might just be what I have on it now but its running smoothly.
Does GPS work on your tablet with CleanROM? I think I will wait for Android 4.2 to reach the tf700 before I unlock it.

+1 here as well I've never had any problem. The one and only complaint front my end is the build quality in the dock. If I pick up the tablet with one hand on the dock, it makes a popping sound at the base where the lock is. Not a huge deal I just pop it back non the less a flaw

Yeah, the build quality isn't excellent but it's far from awful. Try buying an 80 dollar, no brand tab from eBay, then try complaining about the Infinity. Mine only has a tiny click up near the volume rocker and down near the charge port. The clicking is barely audible and the screen isn't coming up, so I've been able to disregard it.

I was putting off unlocking till JB hit. It's here now, but still a bit worried about a $500 paperweight. Might bite the bullet and have fun with some ROM's. I noticed just a few days after OTA JB, it was available to unlocks.

Software wise mine has been perfect but I also got the popping noise after a while and it got worse and actually starting popping apart in the top right corner. I ended up returning it and I'm currently waiting on a replacement. Not having the dock makes you realize how much better it makes the TF700 package.

If you buy an 80 dollar tablet, you get what you pay for. If you shell out 8 times as much, you should also get what you pay for, and for that money I expect a perfect device, not something that is barely acceptable.

But if you get a device with any major defects, you can just return in. Contrary to what you may have read on XDA, it's unlikely that you'll have to exchange the device more than once or twice in order to get a TF700 that is just fine... I'm quite aware that Asus has QC issues, but there is an easy solution - exchange it! Once you have a good device hardware-wise, just install CleanROM and BAM - you have *the* best Android tablet on the market!
I've been 100% satisfied with my purchase, that's for sure! No device is "perfect"...

maybe you should add 11, something like "I've not heard a squeak or a crack from the housing/screen." i'd fail that. after three weeks, my near "perfect" tablet developed a small squeek when pressed along the charging port, and now it is a clipping/cracking sound.

Boy this sums it up.
I would have only returned it once and not for exchange.
Would have moved on like I did with the ACER A700.
Liking the TFI, yet I really don't believe I'll return to Asus on the next tablet.
This hit home for me Mr. _that :good:
I just bought a TF300 (JB preinstalled). And the auto brightness doesnt seem to be work turning it on reduces the brightness to the minimum regardless of the ambient lighting.
Is this a software bug with JB on TF300. or a faulty hardware that i should return ?
To be honest, mine never seemed to work correctly and don't even use it. May not be a flaw with yours
