Power Button won't wake up screen sometimes. - ONE Q&A, Help & Troubleshooting

Hello!
After locking the phone, it happens that sometimes the power button won't turn on the display.
The button is still working, because it is possible to start the Flashlight (long press power button) or open the camera app (double tap power button, can hear the sound).
I'm using the latest lineageos 14.1 version.
Does anybody how to fix this?

I don't think so, because my display got replaced.

You ever thought why everyone else is using Oreo roms without display issues and you can't? Hmm,I see faulty display.

As ridiculous as that may sound i think it's a problem with your button, you will have to desolder this and resolder a new one. I used to have the same problem, button didn't work like 2/10 at first, and that rate kept increasing. With use and tear it kept worsening. I bought soldering iron and replaced the button, it now works freakin' great.

Okay that sounds strange. I can give it a try.

Now that i see this Thread again, it's far more likely that your lcd just died or partially did. Although if it turns on sometimes like your state, "that sometimes the power button won't turn on the display" it may be a bad teared down soldering on either the power button on the lcd pcb. Get it to a repair shop and ask for a check, if you don't mine you cant open your back cover and remove the screws so you let the motherboard pcb exposed, with a high quality picture we should be able to see if the power button is the problem or not.

I'm using a cheap replacement from ebay that I replaced myself,and I'm yet to see any issues with it.

most lcd have the problem. i got a lcd thrice now from different manufacturers had the same problem for some extent
digitizer works fine but lcd doesn't have good connection

My Nexus was also sometimes not waking with the power button. A custom ROM flash (Nexus4Ever) worked well, but still had the same problem. Probably related to this I would notice that when the phone did wake it was sometimes taking a few seconds to do it.
After some searching I found a solution under the lineageos forums -- search for BUGBASH-230 (can't post url here because this is a guest reply). Basically, you have to copy (copy them, don't move them) all tzapps files found in system/etc to system/vendor. It worked for me. There's no more delay in waking up and the problem has been gone for a week now. Before the fix it was occurring at least once a day. Try it.

I have same problem with you and this occcurd after change os nougat to Oreo 8.1 on my j7 prime

It's not the display
I have the same issue on my Nexus 7 with 14.1 installed. The mockingbird replies about it being a faulty display or power button are unfounded considering rebooting the device fixes the issue. Only seems to occur when it's been on for a while or has less than 30% battery.

Did anyone ever fix this? I see this on a few versions of Lineage. Disabling the lock screen in System Profiles settings avoids the issue, but then there's no lock screen!

Not The Display, exactly...
Just thought I would throw in my 2 cent observations. I have a Samsung Relay 4G (t699/apexqtmo). It worked flawlessly with its stock software / and official upgrade (I.C.S. & J.B). Once I upgraded to KitKat or Lollipop, the screen backlight would never turn on after waking the device on a single button push. The difference between these versions of android as it relates to waking the device can be found in changes to power management / wake locks code. I am not good enough to figure the ins and outs of this type of programming, but maybe this will give some hacker an idea of how to patch or work around this particular part of the firmware. Thanks!

Just upgraded form stock to LineageOS rooted and all....display wake up worked fine b 4 now i have this problem also it will sometimes eventually wake up but takes forever and many button presses

So, if anyone is till wondering about this, here is the information i believe to fix this bug, that is if anyone can integrate the change into CM KitKat and beyond for our sad old Relay. github.com/TeamApexQ/apexq/issues/24. Any chance this could be implemented through an apk?

Because I really don't want to shell out $$$ for an F(x)tec Pro

HELP!!! Power Button Not Working!!!!

The power button suddenly quit working today. I left it in my grandparents car while we were in church (boring) and after church, I tried to turn it on, but the power button didn't do anything! So when we got home, I plugged it in, then the screen came on as if nothing was wrong. I tried pressing the power button, but nothing happened. Is there any way to reboot it without the power button (and no I am not rooted, I'm keeping my tablet stock, unlike my DInc )? Do you think it's a hardware (button) problem or a software problem? The button clicks when you press it just as it always has, so I don't know what the problem is
Thanks in advance
Sounds like black screen of death. Nothing serious, just hold power button for 10 seconds, then start it again and it should be fine.
Otherwise root and flash netformer 1.4r2, which may or may not fix the issue.
I already tried that. Lol. The power button itself isn't responding to anything
I had same problem yester day in school. I put my transformer on the desk and nothing else. When I wanted to turn it on nothing happens. In house i put the power cable to it and it worked, but power button isn't working...
You can probably find a widget or three that will allow you to reboot.
DO you have ADB setup? You can ADB reboot.
RMA time?
Mine had the same problem shortly after I purchased during the summer. I ended up having to send it in to be repaired under warrenty. According to the repair sheet they replaced a daughter board.

No one can help you except Asus. Sounds like you need an RMA.
I had a similar problem with my volume button exactly two weeks after getting my Transformer. I promptly returned it to Best Buy and exchanged it for a new one. Luckily I was still within my return/exchange period (by the skin of my teeth).
I now try to avoid using the hardware buttons as much as possible. I use the audio manager app to control the volume and plug the device in to turn it on (I try to use the power button as little as possible). I'm not rooted so I have to use the button to turn of my device.
Those buttons always felt a bit flimsy to me and I see it as the biggest build quality issue with the Transformer.

You don't need Root to have a screen button to turn off your TF.
All you need is the free app 'Screen Off and Lock'
It's an excellent App with a lot of amusing tools for switching the screen off.
I have it installed on my non-rooted Samsung Galaxy SII. The Market says it is compatible with the TF.

Yeah I I'm trying it out. I clicked on your thanks button.
I'll eventually root my TF and try out an app that will allow me to shut down my TF without using the hardware button. My TF is a B7O but I think it an early rootable version.

Good luck with the root and many thanks for the Thank You. Each vote comes in handy when my surgical team check my votes at the end of each week.

You should find one back to you.
Just letting you know that my power button died while the unit was still quite new. I ended up having to send it back for repairs to the dreaded Texas center (at my cost I may add) but they got it back in about a week and it seems to work, at least for the time being. Between that and having had to have my dock repaired this has been the most problematic tablet/computer I have ever owned. It is actually a pretty nice unit in many ways, but build quality seems to be pretty abysmal. What worries me is that if it has so many problems when it is new, what will it be like when it has a bit of age on it? This has also prevented me from rooting it until the warranty is over, since if something like this goes wrong and you can't restore it to stock they won't fix it.
I had the same problem after I got a new cover. The power button did not do anything while in the cover, when I took it out of the new cover the power button works perfectly. The new cover has magnets for closing it. I belive the magnets were causing interference. Everything is good now.

Messed-Up Display

Hello XDA,
My Nexus 5 running CM12 5.0.2 nightly will not respond to the touches anymore infact when I press the power button to activate the display it acts as if someone is touching it randomly messing all the apps that are running and opening and closing many other things.
Furthermore it displays weird and burned lines throughout the screen. It was not dropped, no water went inside the device or anything. If it helps I did install the OTA updates that CM gives us.
I have also attached pictures so you may get a better understanding of my problem.
Thanks in advance.

Hmm I see. Well since a month HAS passed, its definetly not the rom thats causing the problem, i don't know if anything regarding the software could even be causing the problem. Its 100% hardware and by that i mean the screen, you should change it, the touch and also the display are messed up.

I hate to be the bringer of bad news - but your screen is toast. Fortunately you can replace the touch and display components all at once.
http://www.amazon.com/Skiliwah-Digitizer-Assembly-Google-nexus5/dp/B00HN0U168
Here is what you need to perform the repairs - and here are the procedures for disassembly.
https://www.ifixit.com/Teardown/Disassembling+Nexus+5+Display+Teardown+-+liquid+damage/32410
Trust me, it's not that difficult. Unfortunately, it's a bit pricey ($60 for the screen and digitizer), nevertheless much cheaper than a new device or sending your device in for repairs.
Rma
Problem Solved
The screen isn't toast, neither is the digitizer. I have 2 of these phones. The parts which cause problems like this are the main board and the ribbon with the USB connector on it, which also attaches the screen & digitizer to the main board. One was showing lines exactly like this, & also no touch. I put a replacement main board in. Works great now. The other, wouldn't even turn on. I put the main board from the first phone in the second one, it still wouldn't turn on. I replaced the ribbon cable, it turns on and perfectly replicates the issue from the first phone. So now, I have one fully functioning LG Nexus 5, and another which turns on with the same problem as yours. This is good, I started out with 2 of them that were useless to me. So, it appears that your display and touch issues are caused solely by a bad main board. A replacement main board costs somewhere around $75. After swapping stuff around, I have 2 bad main boards, 1 bad USB ribbon & 1 working phone of 2. Not bad, not bad at all.

Nexus 5 restarting regardless of ROM

So I've tried factory wiping and installing a few different roms and no matter which one I go to I keep getting these random reboots. This is particularly troubling when I restore an older rom that I know I was not having this particular issue on.
It is making my phone pretty close to unusable since it will often go into an "Optimizing apps!" speil draining battery and taking an obnoxiously long time to reboot. Not sure what is up. Any suggestions?

Try with a clean flash (or the factory images) without user data/modifications and see if your RRs are still there.

The button will NOT seem to be stuck, even if it is, as the contact is made internally. My bro´s Nexus had this problem, and by the end it kept rebooting constantly because the button was making contact on its own. I fixed it by tapping vigorously at the area between the power button and the camera and that made it work.
A way to know if it is stuck could be to press the volume down key as soon as it restarts, if it goes into recovery, then there is no doubt the power button is stuck.
Don´t dismiss hardware problems, as many Nexus are affected by the power button issue and you already tried software solutions which didn´t work.
Hope you sort it out. Remember to use an app to avoid pressing the button so much, such as when waking the device. I recommend Gravity Screen, but there are many other options.

Holding down volume after one reset actually put me into recovery. Plus it's restarting at times in recovery now :/
I doubt it's under warranty since I got it in feb 2014 x.x

If you got it directly from Google, I'd try calling them up and asking for a replacement even if you are a few months off the warranty period, I have read some stories of them honoring warranties in order to get rid of stock. That'd be true even now that the new Nexus is supposedly releasing this year. Nothing wrong with trying, you might get a new, shiny phone.
That being said, don't worry, it's perfectly fixable. The part that gets stuck is not the button itself, but the part that goes into the motherboard, so don't bother fiddling with the black button. I managed to fix my brother's button by doing the following:
- Clean the area between the button and phone of debris or any dirt that could be causing it to be stuck. This is just to be on the safe side, as it is unlikely that it is the cause of the malfunction.
- Take the case off the phone if you haven't, and then put it upside down and tap vigorously with your fingers in the area between the camera and the power button. It might not work the first few times, but it eventually will release the part that is stuck.
- As soon as you can get it to turn on without rebooting itself, install Gravity Screen, or any other app that replaces the power button to wake up or turn the screen off. You are looking to use the button as few times as possible.
After doing that, his Nexus went for being unusable due to constant reboots to working fine. It's been almost 6 months since it happened so it is bound to work, just don't lose heart and patiently work at it. Tap a bit harder if it's not working. Let us know whether you managed to fix it.

I'm going to get in contact with google. I tried pushing down on the area between the camera and it didn't help much. It has started working again properly after a really peculiar work around. I just don't want to have to be super cautious of a button for the rest of the time i own my device :/

Well someone mentioned maybe trying to clean it out somehow. I tried canned air and that didn't do anything so I formed a seal over the button using my mouth and then proceeded to exhale. It has yet to give me any trouble since then.
Had exactly the same issue, reboots over and over again, couldn't boot to bootloader without reboot...
What helped for me was something I read somewhere else, don't remember where, was knocking on the back cover between camera lense and the power switch, did it 4 days ago and it works since than..

Sounds sexual
You can take the back cover off, and if you are careful there is no sticker or seal that would tell google you have opened the device. It is difficult to pull all the way off, the vibration motor is attached to the case back and comes off with it so it would seem stuck. You just have to keep pulling.

Pressing on the area between the camera and the on switch seems to help a lot of people it didn't seems ot have much of an effect for me. While my phone hasn't given me issues since shortly after I posted this thread I'm kinda worried I'm one drop away from the issue coming back

Would this allow me to repair it?
Yeah but you'd need to unscrew a plastic cover that is inside the phone. Phillips head screws, jewelers screwdriver size. Depends on if its dirt or a broken switch though.

Sorry to disappoint everyone but this is a widespread problem that google is aware of fro some time now. It's not the power button but it's burried deep in the software and appreas to have popped up right after the Lollipop 5.1 up date. Check out all the posts on Google
https://productforums.google.com/forum/#!topic/nexus/IJSOuc7gw0w[376-400]
While it apprears to be confined to the Nexus 5 I have had it happen with my nexus 4 just running stock L 5.1
I hope that casts some light on it
Weirdly enough, my power button works flawlessly on 5 and 5.1. Red 32gb from the google play store. I've opened the case multiple times and put Arctic silver knockoff heat compound in sloppily and without regard, no issues other than sprint screwing up their spark LTE rollout.

Sorry, I disagree. While some instances might be related to software, it has been proven that there is in fact a problem with the physical button getting stuck on Nexus 5 phones. You can check it online and will find lots of hits and even YouTube videos, most of them around the time before lollipop.
Best way to check whether it is software or hardware is to press the volume down key when your phone reboots by itself. If it takes you to the recovery, you can bet your cat that it is not lollipop's fault
So I'm suspecting that I have the wonky power button too but.....
I haven't been able to get it to go to recovery when pressing power down and I've defintely had a few restarts very recently.
More importantly, and something that I haven't seen anyone else post about; more often than not my N5 just shuts down. It's usually when I've doing something with the phone (today was flicking through my GPM library). I'll power it back on and it will boot cleanly and then (more often than not) power down again. Other times it will bootloop, but that's rare. It seems to me that if I let it boot up and then don't touch it for a while, it will stay up but I'm not sure that's consistent.
Anyone else seen or heard of the power button causing a powerdown instead of bootloop?

You will need to troubleshoot this the old-fashioned way. Have you installed any updates, apps, mods or anything recently?
Best case scenario would be that you flash a stock image without restoring apps, kernel or any mods. Run the phone for some time, couple of days or so, and be on the lookout for power downs or reboots. After that, you can try adding a few apps at a time and keep checking. If the phone reboots even with a clean factory image, then I'd have to say the hardware is faulty. Could be the power button, could be something else.
Try it out and let us know

Disabled power button but it reboots my phone if I touch it

Hello,
I have a Nexus 5 with Android 4.4.4 and CyanogenMod 11. Like always, it had been working really find untill today, when it started to reboot and entered in a loop. I found out that it was because the power button was broken and with the lightest touch, it would activate.
Searching through the Internet I found out that many people happen to have this problem. I tried to disable the power button editing a file that is found under /system/usr/keylayout/qpnp_pon.kl, where I had to simply comment the line where the power button was.
Now, if I click the power button it doesn't happen anything, like I was expecting, but after 30 seconds of clicking it, it shuts down and it reboots like if it was an internal error or someting similar that caused that reboot.
Is it possible that disabling it the way I did could cause any type of problem that made it reboot after touching it?
I know it's an internal problem or something like this because when I touch it, it doesn't lock the screen or show the power menu, so the button itself is kind of "disabled", but it keeps causing this problem.
Is it good what I did? How can I solve it?
Thanks!

I had the same issue unfortunately. My N5 is still at LG for repair and it's taking much longer than they told me. Which is good of course. Like most smartphones now though, a 10 second power button hold will forcefully reboot the phone. It's hardcoded in the phone and no matter how much you try to disable it through the OS it won't make a difference until the rogue button is physically taken off the motherboard. If you're in Europe though and your phone is still in it's 2 year warranty I would strongly suggest flashing a factory image, relocking and calling LG (or Google, if the device came from Google).
Hope this helps.

Well... It's been like three years since I bought it, so I guess the warranty is over...
And if I want to disable it, I will have to do it manually and disconnecting it of the motherboard, am I wrong? I guess I'll either have to live with this problem or buy a new phone... Today it's not my lucky day! Hahahaha
Anyway, thanks for your reply!!
Many owners have the power button issue. A competent cell repair shop should be able to replace it.

Yes, that's true, I've found a lot of people over the Internet with the same problem.
By the way, I could finally solve my problem; after searching for a while, I found a YouTube video that showed a peculiar way of solving it... And it actually worked!
Well, it looks like I cannot put the link because I'm under 10 posts :cyclops:
Well, here's the video code if anyone is interested: _QpSSCifxAw
The Internet is amazing! Hahahahahahah
Thanks for your replies!
Are you referring to banging the power button? It wouldn't work for my friend's power button. He had to have it replaced because it failed a multimeter test, apparently.

Yep, exactly!
Like the video said, I bumped my phone a little bit because the power button was kinda stuck inside the phone, and that really worked...
I was amazed! And I'm so happy it worked! No need of having it replaced. [emoji16]

How did you do that?

Just hit the phone into your hand so the power button gets unstuck.
You can see the video I mentioned above for a clarifying idea on how to do it.

SOD (sleep of death)

I noticed, that my 1+1 always works ok on stock roms (cm11,cm13 from this forum) and when i set up Android Oreo or Halogen (7.1.2 unoff) or even Flyme 6, my screen don't want to wake up from time to time, buttons vibrate, sound works, all works except screen. Even though, i noticed one way to wake it up, just repeat the touches some times, double tap to panel (i don't see it), and again, to block the screen... it wake up always, or reboot sometimes, but this is not a variant to use at real situations. somtimes headphones help, sometimes usb cable, but no 100% solution.
may be someone know how to solve this problem? i saw a lot of messages here about SOD, and no solution. just something about a modem or flash stock, but this is a software trouble, may be it is firmware.zip or just one .bin file inside (power management). may be this error can be solved?
I really want to go to Oreo and today i tried to do it, but when I suddenly understood that it doesn't work again (after stock) i decided to go back, no way to use it. may be i should take some files from stock?

that's the way, but not for me. i've just changed my display, i just can check old one, it is not broken, just a dead zone on the touchscreen. but it means that the revision is incorrect, it is something like a driver, i think. i already had the same situation with a old tablet, it didn't wake up anytime after boot, it was discussed at 4pda, so people found, that only one of the 3 revisions works ok at last firmware, i had 2 type of display and could to swith and check it. but it wasn't so good with colors, so i stayed at stock. it seems that situation is the same now.

Why do yoy think so? Stock fw can realize all functions for that display, why custom can't do it at the hardware level? no reason to think so.
Just only one idea - is a revision. Now i can try my old display. And if i'd manage to change touchscreen, that can be a solution. But i don't.

As I already said,the same issue happened to me after I changed my display.I asked for replacement and replaced that damaged display,boom! I don't know what's so hard in it for you to understand.
Thank you for advice. I've just opened a dispute. Today it didn't woke up at stock firmware.

Aliexpress?
Yes. But at first everything was ok. And when i installed oreo it stops some times and Sod started. I tried to use 7.1.2, it SOD's anyway. Then the stock was the solution. I'm already relaxed, and decided that it is software error, but after a few days it started again.
I've accepted this display, but with your help it's not so late to open a dispute. I think it will be ok.

Get ready with a lot of proofs tho'!
to me it happens, I do not know if it is the same as described, but unlocking the screen works everything but not touch, lock, unlock, and it works, what is it due?

See previous page,I've already explained what is the cause of the issue.
I just finished replacing my screen, been waiting for my broken antenna cable and volume button flex to arrive. Everything works except the damn SOD i never had with my old screen. Tried turning off the proximity sensor check and still a no go. The screen turns on fine initially and trying to wake it instantly works all the time, but if I leave it off for any longer than 5 sec probably it won't respond to anything - power button, volume button, double tap and plugging in the usb cable connected to a power source.
Does this sound more like a governor issue? The rom installed is lineageOS (just updated to 10-30 release). Looking up my purchase log to open a dispute...
tested it again, repeated lock/unlocks puts it into the SOD state, doesn't even take 2 sec to do it...
oh wow, it does this even in the twrp recovery. I have wiped cache and dalvik cache just for the hell of it but doubt that was the real cause...

we've got a reverse situation. touch, buttons, sounds, modem works, but not screen (if you lock/unlock it 10-20 times it can raise again without reboot.

i've got the first SOD in twrp mode. it doesn't matter, but at first - no troubles were with that. and now it works so so at home. and if i use it outdoor it becomes very often, but at home it seems that it works ok, just only seems, because if i want - i can do some manipulations (use camera, lock/unlock it etc) and the SOD appears again. but custom os executes SOD more frequently. i think it can be real overvoltage, like people says.
there are many posts here and everyone advices not effective solutions (flash stock, modem, fw ...) at first it helped me, but now i know there is no way, i can just try but ...
long time ago i owned an old tablet iconbit matrix - it has just the similar issue. it boots, but if you go to a sleep mode - it didn't wake up every time. it lights works ok inside, but no image. i had two displays and if i used one in a custom rom it worked ok, but not another one. stock rom works ok with every display. the solution was a display driver, like at windows OS.
cause of developers bugs, it was a little different (not stock-based) and some revisions of display works ok, others aren't.
so, i think it can be fixed, but the solution for me - change a display like the first reply says. Ali seller read this topic and posted me this in a few days after i started this topic:
Your dispute has been processed and the money will back to you in 7~10 working days.
so could you give us a positive feedback, please?
Best regards.
so, i'll order another one, no trouble, i hope this will help me to enjoy my oneplus.

They always ask for positive feedback in exchange for refund/replacement.Bastards,aren't they? @evronetwork
For the sake of other people that'll read your feedback and make their decisions upon it,don't do it! Just complain this bribery to aliexpress staff ffs!
well I wish I bought from aliepxress... I bought mine from ebay to pinch some pennies, and because I was waiting on other replacement parts (which were only needed due to damage occurred during a screen replacement op) to ge here I am way over the protection period. aw shiiiiit, I guess you live and learn
gotta tell you though, the screen is a bit wacky in other ways too. the capacitive buttons do light up but not completely (kinda dark in the corners) and the colors look a bit off. hopefully the seller would honor the refund/return request...
EDIT: whoa... kinda hard to believe, but I messed around with battery profile just for the hell of it and by some pure luck discovered that the "performance" profile (second one from the far right) works just fine and wakes the screen every time. The "balanced" profile and everything below that gives me an insta-death. go figure!
EDIT2: guess I spoke too soon. it sure as hell looked like fixed, but it came back after a while. maybe it is just more sporadic than I thought...
No solution yet? I think, that it can be some trouble with lights (this wire with 3 contacts), because touch starts, but no image. may be the signal comes to the matrix, but it is not enough energy to enable this diods. what can we do? im going to change the back side of the screen.
ow, no way, don't even try, it has combined technology. i disasabled the whole wire, no chance there...

What happened to getting a new display?
I use this one, because it works ok, but only at home. As a home tablet. At the street it fails every time.
I can reboot it if it doesn't wake up. But it wakes up often, so i don't want to order new one now. I want to check my mainboard to be sure, that it is dispaly problem
a bit late, but thought I should update on the situation... all working fine after a (yet another) LCD replacement. Much better color balance to boot, points to QC problems at the supplier's end. If I ever have to do this again, I am definitely going to inspect the new LCD as soon as I receive I receive it.
