Zero brightness. - Nexus 4 Q&A, Help & Troubleshooting

Just got a Nexus 4, works perfectly except for when i slide brightness down to minimum the screen goes off. Like complete black. Is this supposed to happen or a hardware defect? I'm running rooted stock. The only way to fix it was to do a factory reset.

How Black is black. If this screen is completely black ie you cant read anything, in a dark room, then its a hardware defect. However the nexus 4 can really get dim and coming fro a gnex like you, it struck me too at first.

It's dim, but you should still be able to read it in an entirely dark room.

Please provide a snapshot.
Plus, set auto brightness that to on the most minimal level and you are good to go.

Its pitch black. Ill show a picture soon.

Softkeys stuck on dim

Sorry if theres a thread on this already but all I have is my phone so bear with me.
For some reason my nexus s softkeys are stock on dim, they don't change with the brightness of the screen so its really hard to see them outside...any suggestions?

noone?....
They are that dim by design, AFAIK.
So when you go outside, you can barely see your keys?

Can someone please confirm or deny how the keys are supposed to act before I send this in to samsung

I have never seen them more brighter or dim, always just the same. However, on the G2 for example it was possible via kernel tweaks to make them more brighter or dimmer. I'm not sure if its possible for the Nexus S though.
A picture would help.

As far as I've seen they have only one brightness setting.
I am pretty sure, that that the dim keys where mentioned in some review, too.
Compared to a Galaxy S, they are indeed dim. Personally, i prefer it this way, makes it much less distracting when using it in the dark, and on bright days, i have no problems with finding the buttons.

nexus 7 screen flickering

So this only Happens when I'm on Google chrome and I've noticed that ocassionally that the screen flickers, its not crazy annoying but definitely distracting. Have any of you had this problem?
Hopefully any of you aren't epileptic.

Hopefully the next update will resolve this problem.
so set and wait.
So I should just wait for a fix and not return it over and over to try to find a good one. It has a year warranty.
I see it too!

I turned off automatic brightness and I think that solved it. I think it was flickering when it was changing brightness.
its still there with auto off.
And with the brightness up but it so slight u have to be ocd like I am about my stuff to see it. But its easy to tell its not hardware because games like sonic CD are beautiful.

It happens to mine when its on the lowest brightness setting of when "auto brightness" is on. For now I've just set the brightness to max so I don't have deal with all the flickering.. for now.

With my settings set to Automatically lock (immediately after sleep) and power button instantly locks with a visible patter screen lock, my Nexus 7 on wake-up [pushing the power button immediately] either right after an invalid pattern code (where device then sleeps) or waiting a few seconds with no activity until the device sleeps (where the Nexus 7 fades to a black screen) will have a delay in bringing up the lock screen OR sort of flicker presenting some sort of black and white bar lines background at the bottom half of the screen for a split second before bringing up the lock screen. Is this normal or it is in fact a defect?
Thanks in advance!
Not sire about that I have seen it in 3rd patty apps on all devices before. But the flicker we are seeing is like it changing the brightness up and down.

As does mine. I think people think it goes away when not on auto, because the "low" setting is about 20-25% and auto will often bring it lower than that, making the flickering worse.
At medium brightness the problem is almost, almost, non-existant.
It's also not just in chrome as some say, just most noticable on chrome's white backgrounds. I've noticed it in any app with lighter, brighter colors. I just exchanged my Nexus 7, and the new one has the exact same problem. This leads me to think the software problem is the most correct answer.
I get it every once in a while. Full brightness set, no automatic. Ill wait for a fix, doesn't bug me too bad.

I suspect it to be a software problem because in game it looks great. Plus in a new device like this software problems go with the territory.

And mine as well I noticed my screen flickered when my batt was getting down to 10% and my brightness level was at about 1/3. But now its charged and I don't see it flickering yet. I don't know...with Chrome having a bug (lags when scrolling) and the flickering screen...I may be returning my unit? I really hate to because aside from my issues, it's an awesome device!
Don't take it back they well fix it with a update.

Dim Screen at Boot Time / Recovery

So yesterday I was messing around with rooting and setting up CWM. It was quite frustrating, but not for the usual reasons: turns out that my Nexus 7 likes to turn the backlight completely off during parts of the boot process (the google and X logos) and always in CWM so it looks like it is off when it in fact is doing something. To be able to see anything I have to shine a very bright light (using Torch on my phone right now) on the display. However during normal usage, there are absolutely no issues with the backlight.
Any Ideas?
I can try to take pictures of it later, but I don't have a very good camera.
Bump. Anybody?
Same problem here. No idea why it happens.
I contacted Google and they're going to replace it.

Return it to stock bootloader and ROM to rule the changes didn't introduce issues.
I did, it's definitely a hardware issue
Sent from my Nexus 7 using xda app-developers app
I don't mind it actually since it only happens during boot. Not much of a problem here.

Nexus 4 display and speaker

I usually keep my phones on full brightness. I'll deal with the battery draining because I love how it looks with full brightness. Has anyone noticed the display on the n4 kind of adjusting sometimes. I have noticed sometimes it changes to a little darker or a little brighter while using the phone.
I also noticed when I am talking on the phone with the speaker on sometimes it shuts when opening an application or sometimes even without opening an app and switches to regular ear piece. Sometimes it will stay on speaker but go lower.
Anyone having these issues? Its not a deal breaker or anything I still love it. I know phones will always have their issues, I've had ever nexus and the g1. I just want to know if other people are having this issue.

My guess is glitch hardware. Lg is known for making inconsistent quality. Terrible QA. Just because its made in Korea doesn't means its better than in China.

I don't know how you can use this display on full brightness it's too damn bright! Strains my eyes. lol I tend to keep mine around the 25% mark
It's adaptive contrast, runs independent of your brightness settings and there's not an option to disable it. You probably notice it most when moving from a largely black screen to a white one.
I think I remember first hearing about it's use in a Galaxy S2 review, my TV does the same thing on its dynamic setting.

[Q] Any Nexus 4's Without Backlight Bleed?

I've already tried out 3 brand new Nexus 4's, and they all exhibit light bleed around the top right corner.
I know, I know; I'm being obsessive or nit-picky. But, just humor me for a second, and chime in on the topic....
Anybody got a Nexus 4 without any lightbleed whatsoever? You should be comfortable around 30-50% brightness and have no uneven backlighting around the top border....
Does a perfect Nexus 4 even exist?
Thanks fellas
No bleeding here

Minor light bleed at the top & bottom.. although it is very minor. I really have to try to see it. I would say for a normal person, they would think it has "no light bleed". But to us perfectionists yes it's there.
I know this is asking a lot, but would someone with a perfect device mind posting a pic with your brightness turned up with your notifications dropped down?
No bleeding here either and I'm on Rev 11

Lots of light bleed here in the top right corner. Nov 2012 version, rev10
Don't really care though.
No bleed and I bought mine at an insanely bright tmobile at sunset.
Sent from my Nexus 4 using xda premium
Maybe for some of the people who say they have a perfect device, just dont notice it or their brightness is too low..
someone, please, put my OCD worries to rest and snap a shot of your phone with no lightbleed with the notification dropped down with at least 50% brightness.
I will be in your debt.
Is this what your looking for? Sorry I'm half ass sleeping right now.
