[Q] Brightness varies during boot - Nexus 5 Q&A, Help & Troubleshooting

Does anybody else is having this issue?
Everytime I turn on my phone, the screen varies on the intensity of the brightness while booting, so you would see it too bright, and then the brightness goes a little soft and then very bright again. All of this happens while booting.
Is this normal or did I do something wrong?
I have stock Rom, stock kernel and rooted.

Normal.

It's normal (I assume as mine does it). Is it that much of an issue?

I don't mind about this, but I thought there was something wrong with my phone.

Nope, it's perfectly alright. Every Nexus does that.

[Q] This auto-dim "bug" is completely unacceptable...and is driving me beserk
Basically, if I turn autodim off and turn the brightness up over 50%, the screen shuts off and when I press power to wake, flashes for 1/10 of a second and then turns off. The only way I can use my tablet with brightness over 50% is when it is plugged in.
How has this not been fixed yet? It's got to be a software issue right? This is completely and totally ridiculous.

I don't have this problem. I use it at 75-100% most of the time on battery.
I have zero idea what it could possibly be. I'm on the verge of returning and just washing my hands of this thing. It's a shame because the Galaxy Tab will definitely be at a higher price point.
exchange it. Something is wrong. No one else is reporting this issue. I've had my ft stock, running Paul's rom and prime, and all the different kernels. No such problem. Sounds like a hardware fault.

This.
I get that people can get frustrated when something's wrong but the store should always be the first point of call if you've got a problem. If you get it exchanged and it still has an issue, THEN you get to post about it and complain. Even so, at least post in the right forum...
I have this problem and I've seen 2-3 other people with it, so its not that common by the looks of it. I tried to find a solution but I am RMAing mine as there isnt a fix at the moment.

Screen color problem Tf101

turned on the tablet and the screen appeared red color on the place of black. what can be reason for this? or is there any way to make it as it was before?

Not only is some places red instead of black, a number are also blue instead of white.
Perhaps the GPU/SOC is overheating or going bad? I really doubt a cable to the LCD is put in properly or loose, simply because it would be a consistent color (either red/blue/green) that would be off. Try playing an intensive game and seeing what happens. I'd be willing to bet it will either crash or something similar. Probably time to do an RMA.....

reset to factory settings, and after some time turned it on. everything was ok.
that often happens on computors anyways when you overclock the gpu/cpu too much so maby if you keep the voltages low it wont happen again

Boot on recovery (CWM) hold Power + Volume(-)... etc. And do a "factory reset/wipe".
But if the problem comes from an OC heat, I think you will have to install also a rom/kernel without OC. Then wait some hours to start it up.
hope it helps.

[HW Problem?] Backlight stuck at full brightness

Hi,
Got my TF700T one week ago, and the back light seems to be stuck in full IPS+ mode. I can change the settings related, the slider, etc, but the back light is just on, with a intensity like a little sun.
Battery goes away in about 3-4 hours when it runs like that. Have tried factory default, and anything else I could think off, including installing the new update.
Any suggestions? Fixable, or a DOA unit?
Thanks,
/a

If you've restarted and factory reset..there isn't much else you can do but return it. Sorry man.

[Q] Screen will randomly not light up

So my phone has been fine until yesterday. Everything seems to be working except the screen won't show anything. I can feel the vibration from unlocking as if it was showing and I can still hear sounds and the buttons at the bottom and the keyboard all light up but nothing shows on the screen. If I take the battery out and put it back in most of the time it fixes the issue. Sometimes it doesn't even show the splash screen though. Its kind of hit or miss.
I replaced the ROM I had on and put the original battery back in (I have an extended battery) to make sure it was neither of those issues. My guess is something is going out on it. Anyone else have this happen/have a fix?

Also forgot to mention this doesn't happen if I boot into recovery.
Are you using a custom ROM? If it doesn't happen on recovery then sounds like a kernel issue to me... Since the only difference between recovery and normal mode is the kernel they're using is different.

I am, yeah. I ended up going into recovery and formatting everything, it was still acting up for a bit after that but then started working fine. My guess is I had some sort of corruption. Thanks
Same thing was happening to me when I went ham on my kernel tweaking the hell out of it :silly:
Well I mostly fixed it. Still happens randomly when sliding out. If I slowly slide in or out again that fixes it though. Still, kinda of a weird problem.

ok ill try that. but here's the thing. whatever app i use to turn off the backlight of the soft keys. it only dims it to the lowest level and doesnt completely turn it off.
when you look at your phone in a different angle, you can still see a very small light emitting in the soft keys part even when you shut off the phone. i tried reinserting the battery hut it doesnt fix the problem.

Make a backup, do a full wipe in recovery, and reinstall the ROM you want fresh. If the propblem goes away then something is just screwy in your current ROm install and you may just have to set up a fresh install of it.

i hope your right that its just a rom problem because sometimes out of nowhere, all of a sudden when i shut off the phone, the backlights were completely gone(which is what i want to happen).
I'll post the results later. thanks.
by the way, when i used cpu spy it doesnt turn into deep sleep when the screen is off even if there is no apps running.
i left the phone for 6 hours screen off and charging. and only 8 minutes it turn into deep sleep state. the other remaining comes from my lowest speed which is 384. so im joping its just a rom problem.

need help pls. anyone experiencing this same annoying issue?

Wait a minute...when you said the backlight stays on even when you shut off the phone I thought you meant like when you turn the screen off. Do you mean when you physically power off the device?
That's really screwy. If so, something is really REALLY messed up.
Try the following 3 things in this order from easiest to hardest.
1) Remove the SD card. Reboot the phone. See if the problem persists. If it goes away without the SD card, copy your files to a computer, format the SD card, and copy your files back. I give this a 10% chance of working but its quick to test it so why not try?
2) Do a full wipe. Flash a bone stock Sense ROM. Seen if the problem goes away. If it does, wipe again and install whatever you want.
3) Run a full ruu and return to completely stock. If the problem is still there your hardware is broken. If the problem goes away you will have to restart the rooting process. You will have to redo s off, redo superuser, etc. Then flat whatever ROM you want.
Try doing an full ruu back to bone stock. Reroot, and start over with a new ROM. You will have to go through the whole s off process again. But it might fix this. And form the sound of it you have somehow borked things that shouldn't have ever been touched.

Well, when the phone is off, the backlight is already gone. So its ok now. The CPU spy also states that when I turn my screen off, it turns into deep sleep. That one is fixed too. But when I charge the phone and let my screen off, it doesn't go into deep sleep but it consumes the least frequency of the processor which is 192mhz I don't know if that is normal.
I think I have a hardware problem since I sent my phone to replace its microphone flex which includes the lights coming from the buttons. I'll try to send it back to the center since it still has warranty.
Thanks. I'll update you.

Any update on this issue? My wife's phone has many screen problems, but one of the primary symptoms is that the backlight is almost always on in the lower left corner, even after removing the battery and reinserting it, before booting. When I charge it, the backlight gets brighter and I see dark pixelation across the screen. At times the screen has crapped out completely, and it usually appears dark, has some light flickering, blotching, and vertical lines. I'm wondering whether this is an LCD/backlight issue at all or another hardware issue. Don't want to buy an LCD if that won't fix anything. Some LCD/digitizer assemblies have a mic cable, though, so I'm curious about what you found out about that. Thanks
