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 heared a lot of people say I about this, but happily I seem to don't have it or I don't detect it. What is this dock problem about?
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.

I returned my tf701, waited for cyber Monday, and bought the Samsung note 2014 since the nexus 10 2 is so elusive. I put in an escalation request anyway and included a link to this thread in my complaint.

I also saw this issue on my TF701. This seems a "feature" of Tegra SoC
Just picked up an ME572c and I'm very impressed for the price. However I have noticed the screen brightness levels keep fluctuating as if the light sensor is constantly detecting different light levels.
Has anyone else experienced this?

Hi,
i notice this too, but that can be related to the power saving mode. Plz turn it off and check the settings in detail. Maybe that helps.
Further inside the developer options there is another option to configure the auto brightness.
You can change the behaviour from dynamic to immediately or slow mode and active an onscreen lux, gain and brightness value display.
Btw i am not satisfied with the auto control, as for my taste the brightness is still too low in a less lighted room. Sensor is reporting 0 lux already with a brightness of 14 which would be ok for a really dark room & night but not at daytime.
What is your experience?
I tried playing with power saving mode and the auto brightness controls in developer options. While I could reduce the fluctuations, I could eliminate them completely. Unfortunately I found it too distracting and returned the device earlier today. It's a shame as everything else was quite impressive for the money.
I also found the fluctuations annoying, my solution was to turn the auto-brightness off. Honestly I dislike auto-brightness on any device, it was also one of the first things I turned off on my laptop.
I am using Lux app now and raised minimum brightness at 0 lux. Thats ok for me now.

Just bumping this to confirm this works and so that others can see. I used Developer options as well (before I found this post) and noticed the instant setting works best.
One more setting to also double check... Make sure that in developer options under auto brightness that you disable allow change gain...
Even with everything disabled it appears as if something still is changing the display. I particularly see it with something like a reddit browser when I'm viewing pictures. You click the pic, it loads and displays and then 1-2 seconds later the display adjusts based upon what is being displayed. Depending upon the picture it can be pretty annoying. I may have to root and start poking around to find out what is causing this.

Hello!
Im on lollipop, but the problem you had, still occur at me.
Did you noticed this problem, since you on lollipop?
I have the same problem. When i read, or browsing, the brightness changes in 2-3 steps.
Is anyone experiencing issues with screen brightness adjusting itself without you changing it? I'm not talking about auto-adjusting from adaptive brightness - I'm talking about the slider moving up on its own. I keep it around 25% or so often to save battery life during heavier usage, and after turning the screen off and checking moments later, the brightness level will be up around 50-75% (it varies). I've only noticed this since the Pie update, and I'm not sure if it happens while adaptive brightness option is turned off. Anyone else have this issue?
Pie made a change were "Adaptive Brightness" literally means the slider moves on its own(and is now the absolute brightness). Its supposed to be more clever than the "offset" style slider we had before because it "learns your preferences" if you move it manually. I guess the idea goes you just keep adjusting it manually if you don't like the setting it chose and the next time it encounters that level of light it uses your setting instead of what it usually would have used. Seems pretty cool to be honest.

Ah, OK, I didn't realize that. It does sound cool, as long as it starts remembering where I like it. I do move it around though during different times/situations, so I may just turn it off and manually adjust when I need to. Thanks for the info.
The first issue regarding contrast settings is that on 10.2.28 at least, if I set the phone to "standard contrast", sometimes upon waking it, it forgets that setting and looks exactly as if set on "automatic contrast", even though standard is still checked. Just confirmed this as my screen looked rather blue, changed to "automatic" and it remained identical, then I changed it back to standard and it finally got the desired white balance.The point of "standard contrast" is that it should be CONSTANT, not ever changing... I've got the phone 4 days ago (enjoying it overall) and I've got to ask if this has been an ongoing issue or is it new in 10.2.28?
The second issue is that with auto brightness OFF, the phone still bumps to max manual brightness when the sun shines directly on the sensor. It's not as annoying as the first issue but I'd rather it would not do that. This is how the mi 9 behaved since release or just a new bug?
Ultimately, can you guys point me to the most effective way of reporting bugs to xiaomi?
I'm on the same rom version... I don't have any issues with contrast changing like you said but I'm on increased contrast at all times... There's no way of disabling the screen boosting brightness in sun light regardless of auto brightness settings... It's sunlight 2.0 mode and actually boosts the brightness higher then the max on the brightness slider.
S20FE 4G (Exynos)
Sometimes, especially under load and when the phone starts to get warm, the screen will automatically go to half brightness, with no way to go higher than that. When i move the brightness slider from mid to the max the brightness doesnt change at all. Auto brightness is off, adaptive battery too. It doesnt go away if i lock the screen or even after a reboot. It only does so when it feels like it. I've also tried clearing the cache from recovery with no effect. This all started a few updates ago, with the april 2021 patches, and didn't go away.
Anything else i can try besides formatting the entire phone?

This is due to the temperature sensor forcing an override of the display brightness. It's maddening. Trying to use this phone outside in the sunlight for more than a few minutes renders it unusable. There are many threads about this all over the net but no solutions.
I've tried turning off all sensors re the new Developer Settings button. Tried using Game Booster to disable temperature monitoring and max performance. Tried everything I can think of.
Is there a way to disable the temperature sensor through root or mods or some other way? I'm literally about to sell this phone because I use it a lot outside and I simply cannot use it.
