[Q] sometimes screen doesn't turn on again - Nexus 7 (2013) Q&A

Hi there,
I have this really annoying behavior of my nexus that sometimes the screen just doesnt want to turn on which means I have to do a hard reset and the worse is that its happens more and more.
Some days ago I read in this forum something about the light sensor but I couldnt find the thread again
Any idea what I can do?
Cheers
Stephan

Are you undervolting on a custom kernel? That can definitely cause your SOD issue.
prshosting.org

no, its the standard google android rom and it happens with 4.3 as well as with 4.4
The only thing is that the device is rooted but that shouldnt cause a problem

I have this same issue, brand new Nexus 7, it hasn't happened yet today but for the first several days (on both stock and then OTA 4.4) I simply COULD NOT make the thing turn on with the power button. I was cringing hard because my Note 2 had that problem out of the box and I had to ship it back for warranty (for six @%$&'ing weeks), but in that case the button felt obviously sloppy. On my Nexus the button has a very crisp feel to it, I was wondering what I could be doing wrong but it seems to have 'broken in' or something because it hasn't happened the last 50 times I poked at it. Honestly, it felt like a software bug rather than a hardware problem.

I also was running stock and had the SOD. I was lucky because I just had to hold the power button for 15 seconds.

Phone rebooting like crazy...help

I literally have never had a problem like this with this phone, but just recently I flashed the new AOKP jb 8-29 build and after a day or two of using it I started getting random reboots where the phone would crash and then start vibrating in intervals. I couldn't get it to stop unless I pulled the battery. Thinking this was just a bug with the rom, I just rebooted to recovery and wiped and flashed the latest jedi mind trick v7. I let the phone sit for a little bit after first boot, but when I then tried to go through the setup I got the exact same problem. Now the phone crashes like this every time I boot up and even while I'm in recovery mode! Someone please help if you know what might be causing this.
EDIT: Now it's doing this every time I put the battery back in; I can't turn on the phone or go into recovery while it's vibrating like this
Sound like a faulty power button. I've seen many, many threads like yours. Almost certain that's the case. Mobiletech offers a power button service. Check them out

I think you're right because before every time I put in the battery the phone would turn on, but I tapped the power button a few times to loosen it up and put the battery in and it didn't turn on. Is there any way to remote start without having to touch the power button that you know of? Thanks for the advice btw
This same scenario happened to me just yesterday morning. I researched it and this issue does seem to be popping up more frequently among Samsung phones. Maybe power button design is faulty and they're starting to wear out now after a year plus of use? I sent mine off to MobileTechVideos today to be fixed. I feel so lost without my phone!

What I've read is no. Its not the button its self, but the circuits behind the button that mess up. Unless you are really skilled at soldering and can re wire the board, I don't see that happening.

[Q] Any way to disable the power button?

Hey guys,
So I've got an S3 running AOKP at the moment and I was wondering if there was any way to disable the power button. It's been malfunctioning, and causing my phone to reboot constantly. Sometimes even when off it continues to think I'm holding down the power button and cancels the boot process...
Any ideas of a workaround? I'm out of warranty and can't want to pay for repairs at the moment.

Hi,
I am having the exact same issue. Very strange as it decided to do this while checking my email (finger no where near the power button) and I have never had any issues prior to this.
I'm running CWM, CM10.2 and I CANNOT BOOT into recovery (CWM) or ODIN, best I got was the CM loader screen then it reboots.
Even if I disconnect the battery, wait 30 minutes (fully charged) and replace the battery, it attempts to boot itself again. and again and again...
The best videos I've seen involve smacking the phone on the power button side (not going to do that, at least hard) I think it may be a random power button failure. I will be disassembling the phone tonight and trying to open or close the power button contacts and wipe my phone before it goes back....
Yoiks!

It's very random for me too. Sometimes it'll work all day then it'll take like an hour and a half to turn back on.
Quick question, as I've heard this from a couple people. Do you use an otter box?
Regardless I'm 90% sure this is hardware related and has nothign to do with software, because all the cases I've heard of this have had different roms, one of which was stock unrooted.
Pretty frustrating. Not sure I'll buy a Samsung again to be honest.

This started gradually happening to me too and I bought both my phone and Otterbox in July 2012 when it came out. I noticed with my family members' S3's that their Otterboxes were different in regards to the power button (it stuck out more) whereas mine hardly stuck out at all. I got a warranty replacement this past July (2013) and the exact issues you described began happening. It started out as random reboots and as of yesterday, I can't get my phone to boot because it thinks I'm holding the power button down (therefore not letting the boot process finish). I took my phone apart, expecting the power button to be an easy swap like it was in the GS2, but no, it's a part of the friggin motherboard. I also am looking for a way to disable the power button. I'd recommend that if you are able to get it to boot even once, that you make sure to backup all your stuff. Fortunately all my pics are backed up since I can't boot my phone anymore, but other files are currently inaccessible. I wonder if anyone knows if some sort of electrical tape or something could prevent the power button signal from transferring so that we would be able to boot our phones?
I had the same power button issue with my Captivate as well... and thought that issue had been looked into. After 14 months of use on my S3, I noticed this issue appeared.
Solution (well not quite): change key layout to disable power button. Re-map volume down as "power, wake". Yes, by doing this, I am losing volume down button. Also, when the phone is off, I still need to press the power button to power it up. My fix of changing the key layout file won't take charge until after the phone boots up.

[Q] Help - Glide crashes and restarts

I bought a Samsung Glide i927 phone last month in the US, i bought it unlocked as i am from argentine, and i wanted to use it with movistar.
Recently the phone started to crash a lot, by that i mean that the screen starts going white, with horizontal lines and pixels of different colors appearing, then just turn off or restarts itself, only to crash again as soon as it starts an then turns off.
When this happens i try to start the phone and select the shut down option myself to see if the next time it starts it doesnt crash. But sooner or later it happens again.
This problem its happening too often, and not while doing something in particular like running an app or something. Sometimes it crashes just by plugging it to the power adapter, it even shows the white screen with the lines instead of the charging battery image when i charge it while turned off. I have already try to fix it upgrading android or doing a factory reset, but that didnt work.
Anyone have any idea of how to resolve the problem, or if its a hardware malfunction that cant be fixed?
To make things more difficult, as i said earlier im from argentine, and i cant go to AT&T or Samsung to get it fixed or get a replacement. English is not my first language, so please forgive my orthographic mistakes.
Thanks
This really sounds like some hardware problem, but to be safe, learn how to use Odin and use it to revert your phone to completely stock condition (cleaner than factory reset).

I tried to do that, but the first times when Odin try to reboot the phone it just freezes and i have to unplug it. After many tries it finally finished, but the phone keeps freezing and crashing.
The phone even crashes while turned of and conected to the power adapter.
Do you think that with LiteROM 0.9.0, that might fix this issues?
I've got reboots too, try to disable auto brighness
It helps for me

Power button issue
I am having a similar problem. At first, it just happened on rare occasions. However, today, it started doing it repeatedly. The phone was unusable. I did some checking around, and it appears that the power buttons on Samsung phones are prone to sticking. Some people suggest you actually remove the battery and slam the power button against a table. I wasn't going to do that, because I could just see it doing even more damage. What I did instead was firmly tap the power button repeatedly. It seemed to unstick the power button and allow the phone to function again.
Another alternative is to have the power button replaced, but that might be a hassle.
First of all, sorry for my bad english.
I bought it on amazon a few days ago, I have the same problem...
I thing aznemesis is right, because my power buttom is very sensitive, in fact, some times, when I press the button smooth and fast, to turn off the display like, the typical menu appears as if I had pressed the button for much longer period. Which proves your theory. The problem is if I hit the button over a table and the button breaks here in Chile do not exist spares of the terminal
Well, I did. I couldn't stand the desire to do so. After nearly 18 hours, the terminal isn't rebooted again.

The horizontal lines on the screen sound as if it is an overheating issue. What were you doing before your phone shut off? Are you using the factory charger?
cure found
take the battery out...blow on the power button with some compressed gas to get the dust out....then pour a drop of silicone based lubricant on the power button so that most of it gets in the gaps...then hit the power button a few times....haven't had any reboots since then

S3 Wont Wake Up

My S3 is running stock 4.4.2 and isn't rooted (though it has been in the past). At times my phone will not wake up after the screen turns off.
I have to pull the battery to get it to work again. This doesn't happen all the time, but it can happen 5 or 6 times a day. This has been
happening for about 4 months. I did a factory reset and the same thing happens. There is no rhyme or reason to when this happens.
I have read a bunch of posts about this, but there seems to be no definitive answer. Some say do a factory reset, which I did. Some say
it is the version of Android they have, but this goes back a couple of years and everyone is on different versions of Android.
As a habit, I always press the power button to turn off the screen so I do not make any pocket calls. To use the phone, I press the power
button again, or the home button to wake it up.
The phone is 2 1/2 years old and except for this glitch, it has worked flawlessly.
Any ideas?
Thanks,
Ian
Just a guess, but probably a faulty power switch. It happens fairly often, but usually displays different symptoms than yours. It would be the first thing I'd focus on though since it's very unlikely it's software/firmware related.

My thoughts too are that it is an hardware issue rather than firmware. Had a similar problem once and it turned out to be the power button. However, with a device of this vintage, you can never be too sure.
Good luck!

[noob inside] - Screen unlocking problem, faulty device or android bug ?

Hey there guys , I've been searching through the forum topics about my issue but so far I've found nothing close to my scenario.
A few months ago I bought my first HTC phone (M8). Its a great device for sure , despite the fact that I had to return it back twice.
First time it was a faulty microphone , so they sent me back a brand new device. Great isn't it ?
However recently I've noticed a few .... let me call them 'glitches' .
Let me give you some details on what I've experienced with the device:
Despite the issues that i'm going through ... the phone works great, but...
Sometimes the screen wont turn on when I'm receiving incoming calls (same goes for the alarm clock) but the phone is able to recognize touches - i've managed to pick up the call when I swiped the screen in the area where the "green" answer button appears .
The above issue doesnt happen so often but the thing that bothers me is the unlocking issue.
At first I thought that it was stuck or faulty power button.
When the phone is idle for some time and I pick it up and press the unlock button ... nothing seems to happen I've tried pressing it hard ... i've tried pressing it gently ... i've tried pressing it multiple times until the screen wakes up .
Same goes for motion launch unlocking .
When I use motion launch to unlock it the phone only gives me a vibration feedback ... and thats it until I try harder to bring the screen back to ''life'' .
(I can also press my security pattern buttons while the screen is dead and feel the phone vibrating , BUT NOT ALWAYS , sometimes is just .. dead )
I already sent the phone back describing the same problems and they just flashed the firmware , which did not fix any of the issues.
Stock Rom android 5.0.1 , not rooted
Soo what do you guys think? What can I do next .. is it android bug or a faulty unit ?
is it possible to be a sensor problem (proximity , accelerometer)
Already tried factory reset and dalvik cache wipe.
Any advice would be useful.
Thanks for taking your time .

I have the same issue. There are times it takes me hitting the power button 20 times for it to finally light up but I can press buttons with it black. The weird thing is it does it on every single ROM but I havent noticed it on Stock...maybe I'm not using stock enough to see. I'll probably throw stock on there today and take it into sprint and let them replace it.
I have the same problem whether it's on stock or custom ROM (KK or L). I am pretty sure this is a hardware problem. Unfortunately, my m8 is out of warranty so HTC won't fix it for free. I read it some where that it could be a faulty proximity switch so shining a light beam to the top part of the phone may wake up the screen. I haven't tried it yet because every time it happens, I don't have a flash light handy. It is an annoying problem to say the least.
When this happens, I pushed the power button, the volume up button, and swiping the screens. Eventually the screen would wake up and every thing works fine... until the next time.
Its a ****ing pain in the ass.
however none of the sensor reading apps report a faulty/stuck sensor.
the wors thing... I've already sent my phone for repair, describing the problems in details. .. and it took them a whole f*cking month to bring it back to me with no results.
I don't think they will replace it because its a problem that takes time to be experienced...and no one is going to wait for it to happen. ...
Any other ideas?
Should I wait for android 6.0 or should I try a custom rom too see if these problems presist.
Fml I love the phone but this is frustrating.
I have the same problem I think. I just bought an M8 on Ebay. I am S-off, unlocked and rooted, using the Viper Rom currently. I have also tried AICP, the stock Tmobile Rom and a few others. Same issue.
If I double tap, I feel the screen vibrate, but nothing comes on. Then, I keep pushing power button a few times. Sometimes it comes on and sometimes I am too impatient to wait, so I just hold power and volume up.
I also know that the phone internals come on, because after that vibration, I swipe up and push the screen a few times. Then, when I am fiddling with the power button and it does come on, I do see that there is an app already on the screen.
I think this is a rare issue, as I haven't even been able to find many posts regarding this. I may have to get a new one if this keeps going on so bad.

I am experiencing the exact same issue with my M8. I have seen a lot of people stating it may be a hardware fault related to heat and internals but something about how it reacts seems software related.
I really hope someone who has fixed or uncovered the reason comes forward. At this rate I may be switching back to a S4 LTE-A.

I think it IS hardware related. I was able to return that one and got another M8. No problems at all.
