Hi all,
I picked my nexus 7 up yesterday and had a play around with it in the afternoon at work. When I got home it wouldn't turn on though. It appeared as though it was booting fine but the screen wouldn't turn on after boot.
A little googling around and I found a few threads describing the same situation blaming the problem on the automatic brightness settings.
I've reset the device to factory twice and even flashed the factory firmware again in hopes that it was a software problem. Alas nothing has fixed it. When the device is in dim lit areas the screen refuses to turn on. If the brightness is set to manual then there isn't a problem with the general use of the device although I did notice that the global brightness settings didn't seem to apply to some apps (Google Movies) and the screen liked to turn off while watching videos.
Anyway just wanted to put it out there that I believe this is another hardware problem that some people may dismiss without too much thought and use manual brightness.
Regards

Literally the same exact thing happened to me. Contacted google and they're replacing it
I have the exact problem!! At least you can initialise your device when unbox
I don't even have a chance to do that, as the screen light always turns off!!
I have contacted google for replacement, but it just takes me long time for a further response!
How disappointed!
Hmm, I would run GPS Status and Toolbox and test out the light sensor with that. If there is a hardware issue, the sensor probably won't detect light change at all.
I think had this problem, took it back to the store I bought it from the next morning
When I turned the screen brightness down manually, at a certain point and below, the backlight doesn't seem to be on?
The sales guy said it was a backlight issue and had no issues replacing it straight away
Got another one no problem, and tested in store and its behaving fine

Hey guys, I was wondering if somebody would be able to maybe help me diagnose the fault\problem part with my non-working diamond...
Basically I went to a club one night and the place was unbelievably steamy / humid. My phone was working one minute and then the next it wouldnt display anything on the LCD. The backlight was working however.
Since then I havent been able to get an image on the screen although when trying to turn it on, it seems to go through its startup sequence (backlight -> vibration -> beep (i think))
I havent had any power to the phone since a day after it broke (a few weeks ago).
I'd like to get it back working again but dont know exactly what part i would need to replace. I'm fairly competent with electronics .
Any help/advite would be appreciated!
Haha, ok that's odd...
I've plugged it into my pc to get some data files off about an hour ago.. forgot about it and just looked at it now and the screen is displaying!
It is displaying and accepting input although it was flickering at first (like pixel shifting). but i pressed the power button to standby the screen and pressed it again and the display is fine with no flickering ?
Ive moved the phone about and shook it quite hard to see if there's any loose connection but the display still seems fine..
Anybody have any ideas as to what it may be?
I'm not going to deem it as fixed until I know what the problem was/is lol
cheers guys
Ok screen actually keeps flickering nonstop, and sometimes 'fades away' to gray/white/black
comes back after a few seconds though
Looks like a faulty connector?
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
I have recently purchased this phone via swappa and haven't had any issues prior to this and that has been three weeks (other than a light leak).
The issue that is happening is the LCD will not turn on. When the phone is unlocked via knock on or power button you can move your finger over where the lock circle would be and feel the vibrations showing that it does register the touch. Then usually I would just hold the power button till it rebooted and this would sometimes fix the problem, on a side note the boot LG logo and boot animation do not show up during this time simply the lock screen would randomly appear.
That is problem, now on to what I tried to fix it. I have put on an entirely different rom and the problem persists, I have also flashed a different kernel on the stock rom with no avail. I at first thought it could be due to a faulty proximity sensor, but the last time the screen was on I checked it with sensor box. One way I have been able to reproduce the problem is after locking it putting it in my pocket and waiting around five minutes, this then will make it so the LCD does not turn on ( Which makes it seem like it has something to do with deep sleep). Also something I just found since I was actually able to find the power off button, the screen also won't turn on when the phone is off and plugged into the charger (this makes it seem like hardware issue). It seems like as long as I keep the phone from going to deep sleep the LCD will turn back on.
Some of this makes it seem like a software issue other things make it seem like a hardware issue. I just was wondering if anyone had any ideas or if I need to buy a new screen, if the mobo is bad, or if I could fix this with software. Any and all ideas are welcome.
Thank you all in advance.
When I bought the watch back in November, the screen would stay ON all the time. I know it to be a fact because I used to leave it on a desk without ever touching it (for hours) and it would always display the time (it was like having a desk clock, for when I would rather not wear it to have more comfortable wrists while writing or that sort of things).
Also in the train (I used to travel a lot in that period) I would leave the watch hung on the wall while sleeping (at night) and it would not turn itself off, so I could check the time in case I woke up in the middle of the night, without neededing to reach for the watch.
Recently (it was January) I noticed that it does not work like that anymore. After a very short time, the watch screen goes off. It is still in standby: it goes back on if I touch it or press the button.....but I want it to stay on 'without limits' (in dimmed mode). It was like that before.
Somehow this is the behaviour of the 'keep screen always ON' setting.....but in fact, that setting is already set to 'ON'.
So is there some kind of firmware update that changed this behaviour? I would like the clock to not go off when it is not on my wrist, sometimes I just need to keep track of time AND have my wrists free....and it is not possible anymore.
nothing?
It is actually a key feature....no point in having a watch that doesn't show the time unless you touch it (if you leave it on a desk or simply hung on a wall at night). Also I wonder why it changed (did not do this last year so I thought it must be some update but could not find anything in the changelogs about this).
You have the Setting enabled in Android Wear for keeping the screen Always On?
My screen only goes out when on the charger. When I had a Samsung Gear Live, it would stay on while on the charger, via the Developer Setting on the watch to keep the screen on while charging. But that has never worked for me on the "R", not even last year.
The screen of the watch goes off while charging (although I remember it being different back in October...).
The settting for 'screen always on' is activated. I activated from the watch, from the phone, restarted the watch, nothing worked. The screen goes off after a while IF I DO NOT wear the watch.
No problem if I wear it....that means there is some connection between the screen going off and the accelerometer :-/
But as I said, I need the watch to stay on even if I am not wearing it (working at a desk or similar when I can't wear the watch, I would look at the time at the watch lying on the table). I am sure 1000% it did not turn off before (started in January, or at least I noticed it in January). I read all the changelogs for all the updates and I did not find anything about this.
Can someone also try? My brother has the same watch and his also goes off if he does not wear it. I find this really unneeded. At least they should have put a setting available.
You best option is Wear Charging Widget. It will keep the screen on when charging. Although it does dim a bit, like a night clock in a mostly dark room. It is the only option I've found that works.
I wanted the "R" to work like my old Gear Live and keep the screen on when charging and even when not wearing it. But I've never found a means for that to happen short of Wear Charging Widget.

Yes it looks it is like that now. Maybe you bought the watch after the two last updates (501 / 502) ?
Would be nice if somebody else, besides me, could confirm that in fact the watch was staying on (dimmed mode) all the time even without wearing it in the previous months (release date to December).

I've had my "R" since last year, before v5 came out for the watches. And the "R" never kept the screen on while charging. I never noticed it involved simply not wearing it. Since when I'm not wearing, I'm charging.

Screen shuts off completely
The screen on my GWR has started shutting off, completely dark not dim. I checked the settings and it is set to "Always on screen": ON.
This is a fairly new problem, it did not used to behave this way, I could see the screen dim, and move my wrist and it would go bright and display "OK Google".
Any ideas on how to fix this bug? Or do I/we need to wait for a software update/fix? Current software version: 5.0.2
Watch is not very useful if I can't see the time without having to push the crown/button.
Anyone else having this issue?
Screen is working again.
Had some time to try some options, did a "Reset Device" and the screen came back.
Lost all the apps I had loaded on the watch, not a big deal, wasn't using many of them.
Guess I can just download them again from the play store, if I want them back. Something I loaded onto the watch may have caused the loss of the screen.
Last couple of apps I downloaded were CompassX and a charging app that shows charging progress while charging.
Glad to have the watch face back.
I'm having the same problem as you. The ambient mode won't come on. Instead of dimming to ambient mode it now just goes dark completely (like when it is charging). I would love another fix before I have to reset the watch. Any ideas?

Bumping this. I reset the watch. Went about two weeks and now back to the same problem. Ambient mode has disappeared. It's just black all the time until i turn it back on.

I confirm that I have this trouble also in normal use, previously it worked fine and would stay on all the time if that's what I wanted.
Am very tempted to reset the watch after backing up.
I have nearly the same problem. For months now, when my screen dims, it goes to a very dark/dim red. I've removed all programs from my phone and did a factory reset on the watch three times. I'm not sure what else to try. Is there a way to flash the memory? It seems like a setting is stuck in the non-volatile memory.
I was having the same problem and found that I had theater mode set on. Switched to off and now works great.

I'm experiencing the same. On my watch it seems to be somehow related to accelometer. Almost everytime, when using LG G Watch R in golfing, it starts to shut down the screen. It doesn't wakeup even when tapping the screen.
I haven't found other solution than resetting the device
Same issue with 5.1.1
I had this issue with 5.0.2 and hoped that the next update would solve it but sadly it persists in 5.1.1 .
Theatre mode is off, Always on is on but still the screen blanks, showing the ambient mode screen briefly before blanking.
I've reset multiple times, occasionally Always On comes back but only for a short while.
Always on is a feature I really like
Fixed it on mine
I had to turn wrist gestures on. With it off screen on doesn't work.
I have the exact problem on my GWAR, software version 5.1.1. I bought my in December and it never happened until now. It started happening yesterday all of a sudden. I tried factory reseting it through bootloader, throught settings, uninstalling the Wear app, uninstalling the watchface i was using, and still nothing.
Here is what I did to fix it (and i know its overkill): Uninstall Wear app, clear google play services data and reset the device through settings. Now it's finaly working.
I have a strange problem, well a few. If I lock my phone (C6903) using the physical button I can't unlock it again. I try for about 5-10 minutes sometimes and it just wont work. If I hold it down I can feel it vibrate as if it's bringing up the power menu but the screen just stays black. Eventually it will randomly wake up then I can play around as normal. If I leave it to lock itself I can unlock every time, fist time no worries. This is what pointed me to it being a SW problem rather than a hardware problem.
I also noticed that when I do have the screen turning off in the dark, I can see that the screen is still lit up! Just it is black, not completely asleep. It's really quite bright when I have it next to the bed. Also when I am outside I can't see the screen at all really, even with the brightness turned right up.
It's really strange all these happened about the same time. I figured maybe it was a ROM problem and a fresh install of stock ROM would help. Tried it and at first most of these problems went, just the fact I still couldn't really see the screen in the sun. I tried another ROM and at first was just the same but then these problems started again.
Has anyone had any or all of these problems or got any ideas what it could be? I am left thinking now that the problem is more likely hardware related as the problems are so sporadic and happen whatever I have installed.
Any help / suggestions would be appreciated but I have the feeling I will have to just admit the phone is dogged
You say that most of the problems desapararecen to install a new ROM, it is likely that installing something extra to be the cause, I was introduced me something similar with Expoxed Notifications Module.
Try a clean installation without installing test applications to determine if the problem recurs.
Thanks, yes I guess I will try that, bit of a pain having to reinstall apps after every install and restoring messages etc so I might just put up for now.
I also have realised that the screen not turning on and the screen staying on but black happen at different times. i.e. I can now randomly turn the screen on and off no problem (don't think I have installed or deleted any apps or changed anything), but the screen stays awake when off. When I was last not able to turn the screen back on after turning off the screen actually went to sleep. Very strange
