Nexus 4 Lock/Power Button Issue - Nexus 4 Q&A, Help & Troubleshooting

Anyone has experienced problems with the power/lock button? My seems to be loose sometimes. I need to press it two three times before it unlocks. Sometimes on pressing it once it unlocks and locks itself again.
Any similar problems with anyone?
Rooted with stock rom and franco r183
I had this problem on Franco r182 and r183
But no idea whether this is software or hardware related issue!
Thanks in advance!

I've got the exact problem with power button. Maybe it's hardware.

got the same issue. I have made a work-around by having volume key wake up the device (CM10.2 ROM) and use Screen off and lock from playstore and have a shortcut to lock the screen and use the power button only rarely.
It looks to be a hardware issue. Maybe after sometime I'm planning to open up the phone and see if it can be set right

Make sure you are not undervolting too much. Set the screen-off frequency more than 384 & check if it improves.
I was doing 700mV at 384MHz on screen lock & it was apparently causing the power button to go irresponsive.
Had to press two times to get it recognized.
Please report back what you experience.

Even i have the same issue. What can be done now? I have bought the phone from US and now i stay in india. So i dont have warranty. Is it a button problem or motherboard problem??

There's a guide on internet on how to replace the button. If you are a hardware techy guy, you may try that. But first make sure you tried my software workaround.

[Help] weird back button, event fires twice

Sometimes my backbutton fires twice. Its very annoying when browsing and going a page back and it actually jumps 2 pages back.
I checked the behaviour with the app "KeyEvent Display" and it clearly shows that sometimes 4 events are fired instead of 2 (keyup + keydown).
The app requests root, but you dont need it for only testing the keyevents. Can anyone confirm this? Thanks
Mine does exactly the same, from what I've worked out its related to the phone running slow but I have no idea how to fix it, if we find an answer if be very grateful its very annoying!

same with me, only on some apps though like tapatalk and root exploerer
Same here. ButI figured a way-out. just press it and take you finger off quickly then it works normal.
same here and same solution, press it quickly.. been living with it for 3 months already.. it just makes me sick sometimes...
I have contacted se-support and pointed them to this thread. Waiting for reply

Tested a bit more. The menu button is also haunted here. Fires sometimes multiple events like a fukn uzi. I really hope its not hardware related and se will fix the softwarebug

I feel left out haha ive never had this problem. I have however had an issue where the screen decides to freak out and decides to do things at random, it gets annoying when im typing and all of a sudden all the keys start being pressed on thier own.
locking and unlocking fixed is temporarily.
Does anyone have a custom rom flashed with this issue still happening? That would tell us pretty quick if it was hardware/software related.
I have had this problem too well since i upgraded to 2.3.3
I have a UK Sim free generic handset unmodded.

All the custom roms except for CM7 are based on the SE stock rom anyway, so if anyone on CM7 dosent have this problem the info would be useful
I have same issues with this for the up and down arrow it always post two key strokes in Bruce lee. I can't do some special moves and finish moves because of this I am wondering if I should try and get a replacement Verizon stock ROM
Could the double back button issue be caused by the circle button?
Maybe as you press the back button the back of the screen also pushes the circle button?
I dont have this issue btw.
Tbh i have only noticed this problem if i have the phone in my right hand and i use my thumb to press the back button (reaching over the phone to the back key). If i use the phone in my left hand and use my thumb no problem lol.
If i use it normally (phone in 1 hand and using a finger from my other hand) to press the keys i do not have this problem..... Strange
Well, I think I worked out what's happening. Try holding the 'R' shoulder key and press the back button.
I imagine what is happening is android is picking up the shoulder button press but it doesn't do anything. Then pressing the back button fires the event twice. The same way you can fool windows into repeating the wrong key when you hold 2 buttons down (may be fixed in windows ).
Now the question is, how the hell fan you fix it?
I'll submit it to SE later on tonight and see what they say.
EDIT: definitely seems to be certain apps. It doesn't happen in settings but does happen in tapatalk.

Back and Menu buttons sometimes don't work

Heelo.
I have noticed that sometimes (happened to me 3 times in 4 weeks now) while doing random things (most recentone was when i was looking at a picture on facebook and wanted to exit the picture), back and menu buttons under the screen don't respond. Home button works, touchscreen works, but menu and back key doesn't. In order to make it work I have to turn the screen on and back on so that they start working. I am using OMEGA 3.1 ROM and Faux 003 kernel.
Is anyone else experiencing the same problem?

Check if on stock rom it doesn't work either, or ask in the rom/kernel thread.
Sent with Samsung Galaxy S4 (GT I9505)
As I mentioned it happened 3 times in about 4 weeks now, so it's not a kind of thing that I could test with other roms, because it's very very rare. But I have also noticed that sometimes the same two buttons are less responsive than other times (like sometimes I can barelly press it with a tip of my index finger and it responds, but other times it does not respond when touched with point of finger, it only responds when I touch it with the pad of my finger - does it have something to do with electricity or softer skin on pads of fingers?).
Thank you
I've had this a few times in a bit over a week. Doesn't bother me as it's pretty rare and most likely a bug that will be fixed or possibly bugs in the apps themselves.
Good thing home button still works.

I also think it's a bug. Just had to ask as I didn't find anything with google
Thank you!!
I think he asked if you could test on a stock rom so you can see if its a hardware issue. Ive had mine for almost 4 weeks now and my back and menu button never failed to respond so far. Im on stock btw.
Same thing has happened to me a few times also.
I will be using an app or something, attempt to push the back button to get out of that app, and all of a sudden both the back button AND menu buttons die.... u press the area where they are located and nothing happens, no vibration, no light up, no nothing. The only way to fix it, is to restart the phone.
Only happens very rarely - and hard to guage when it might occur and repeat, due to its random nature.
Same thing happens to me. Also very rare, it's happened twice in 1 month

[Q] Power Button Issue?

When I first flashed stock 4.3, JWR, my power button worked flawlessly, every click would turn it on or off, now that I'm on PA 3.99, I have to press the power button multiple times to have for screen to come on or off. Sometimes it works on one go, sometimes it doesn't.

That's changing some things... For me it's not power button malfuction, but PA may causing problems with screen drivers responsible for unlocking it... Maybe you've made dirty flash? Try flashing PA again with full wipe and report results

Well it's both for me ;-; is there a fix, I feel the phone isn't noticing that I'm trying to turn on the screen
Sent from my Nexus 4 using XDA Premium 4 mobile app
My power button is the weakest link so far, but I use touch control to counter. Also, how do you have your phone set up(kernel wise)? And If pa is the problem then why not flash another Rom? If not to solve your issue, then to confirm that pa is the culprit.

Before that, Do a clean install most probably try a different ROM(Slimbean v1.6 :good
You can use Franco kernel he has implemented double tap to wake feature in his kernel. :good:
I am using the same.
Press thanks if I helped. :good:

If you go Slimbean and Franco make sure you download the jwr kernel and not the jss kernel. Fku will download the jss kernel by default as slim is one of those hybrid roms.
Remember, Franco's double tap is different from touch to wake in the sense that you can't slide to sleep, at least not yet.....back up your apps with titanium, your sms if needed, reset your phone, flash Rom, gapps, su if need be and you should be good.

Lg g2 sprint variant "Knock on" feature broke

Well. It worked up until about 20 mins ago. Then randomly just stopped working. Ive rebooted, shut down, enabled and disabled the feature in settings. Fixed permissions for the heck of it. Cleaned the screen. Reset calibration, etc. Nothing seems to work. I can double tap to shut the screen off easily, and it works flawlessly, but trying double tap to wake is completely useless. Any suggestions?

Well thats ****ing depressing

Tons of lg users are experiencing this issue. Its a design flaw with a hardware component that easily breaks. Wonderful build quality -_-...right. So only option is replacing the phone. But to how soon, until the other one breaks. So its kinda like. Well. This blows. I suppose Ill install a custom kernel and enable screen wake features that way.

Okay. So after hours of tapping. Which might i add. My fingers hurt, I am now able to activate the screen. Pausing after each tap, using my finger print area to tap "not to be confused with finger tip". The screen will activate. Also note, the standard two taps works sometimes, but with four presses, i seem to get the best results. Give it a try people. I have a theory the hardware has not failed. But yet, the activation area pixel size value changed. Either due to a conflicting app install. A intermittent system glitch etc

I'm having the same issue with my G2. Knock-on/off was working fine. Had the phone in the sun for a little while (maybe 2 hours) and the knock-on has stopped working completely. Used a drawing app on my screen and found no dead pixels or strips. Knock off still works perfectly though.
This could also be an issue with your proximity sensor. If something (screen protector, finger, dust, etc.) is blocking your proximity sensor, it could be reporting to the phone that it is in a pocket, and to keep the screen off. Try to clean that area, and avoid obstructing the sensors "view". As for the leaving it in the sun, you could have damaged the sensor? You could test it by making a call real quick and see if the screen turns on when you pull the phone away from your face.

The sensor seems to be working fine. Just tested it.

Ya i got the same problem....at home it works perfect but when i went outside in the sun i can double tap like hell and screen didnt turn on(it turns on but cant see anything because its too dark like screen brightness is lower than low)...also power button didnt work...the proxi sensor is ok...i run the test menu and it shows that everything is ok...i also sent it back to my carrier and after a week of testing got it back. They found nothing and said that my described problem is a "feature".... sometimes it turns on after tapping und pushing the power button like hell and sometimes it doesent..
Your screen turns also on with very very low brightness or it is off? When u look really really close u can see it...for example hold power button and u can hardly see the white power off/reboot popup...but i dont know where the problem can be...germany d802 version..(Sorry for my BAD english)

My screen turns completely on and off when I use the button/knock-off feature. I'm going to take it to a technician today and see what they have to say about it.
First, What are you running on your device? Stock? Rooted...

This^. For me I have to use my entire thumb or even palm, but it occasionally works.(still like 1/30 tries). This leads me to believe that it is software related. This one issue is killing me. I hate using the power button on the back so I only used knock on. Now that it's not working I'm hating this phone. Knock off works great and I know knock on is kernel based so maybe someone can create a kernel that fixes this issue.
This did work for me. Fixed the knock on feature on my D802.
Credit: Smith I Run (Thread from android central. Can't post link to thread)
There is a solution; (not sure about it, my friend had the same problem and he fixed it with this method)
Open dialer menu and type;
5689#*980# (Sprint)
3845#*801# (T-Mobile)
3845#*803# (AT&T Canada)
3845#*802# (International)
3845#*800# (At&T)
3845#*980# (Verizon)
And when hidden menu is showed up, go to "Settings"
and go to "Update Touch Firmware".
The touchscreen won't work until after 5 seconds, Wait for it and if touchscreen gets working, exit the menu.
Lock the phone and try knocking on the screen, It should be working :laugh:

[Q] Swipe + Pattern to Unlock

Hey all,
So went from the S3 to the S5 recently and have noticed one thing that sucks about the change.
I can no longer use swipe + pattern for the lock screen.
I have setup just pattern unlock, which should be fine, however, one thing I have noticed is, the power button is often bumped in my pocket and this makes the lock screen available...
Then, to make matters worse the new screen is soo sensitive, it starts swiping patterns all over the place in my pocket! (or trys dialing emergency numbers)...
This was never an issue with the S3 when I had swipe + pattern (or very very infrequently was).
Because you had to make it past the swipe to do anything else, and it was only once in a while that it would make it past the swipe.
Now, I could enable just swipe with the new phone, but, two things, I then have zero security and when it does unswipe, it will do who knows what with full access to the OS.
I would love to get dual lock back, is there anyway that people know of?!?
Any help would be very very appreciated!
Aaron.
