Disable capacitive keys on rooted note 4 - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi,
I recently water damaged my phone (via the usual toilet method) which resulted in the back button activating every few seconds. The phone is definitely dried out now it's been in the airing cupboard a few days in bits. I just rooted the phone but can't find any new posts for disabling the buttons on a note 4. I really want to use the phone to take photos of a wedding I'm going to this weekend and will be a bit gutted if I can't as I don't own a separate camera (it wasn't as good as the phone camera so I got rid, grrr). Any help will be greatly appreciated as i will be able to save snaps of family I haven't seen for a long time.
Thanks

removing key 158 from synaptics_rmi4_i2c.kl and generic.kl under /system/usr/keylayout might work.

Thanks

Thanks for replying. Can I do this from my pc? I can't do it from the phone directly because if i open an app it exits because of the back button issue.
**Edit. I used root browser and after a few tries and being very fast i did it and it worked!! thanks for your help. navigating that fast reminded me of speed playing sonic. you have to know where everything is!!!
you just saved my weekend!!!

[Q] Replacing Touch Digitizer fix NonResponsive Screen?

Hey everyone my HTC HD2 got the Non-Responsive screen problem a week ago, & did a lot of research and found out that it was most likely a hardware problem with a cable..... So a lot of people would tell the people with the problem that the "Touch Screen Digitizer" is dead (like the cable), or it needs to be cleaned... pretty well go out and buy a new one... BUT I have never found evidence that someone has done this and it has successfully "cured" their HTC HD2 Non-Responsive touch screen problem...
So I was looking for anyone on the forums that could confirm this is a solution or give me any tips on what I should do.... AND no I don't have enough money to get a new phone, nor do I live in the USA so I can't send it in to fix it...
This is what I was going to buy for it:
http://www.ebay.ca/itm/NEW-OEM-HTC-H...item519a3d2e45
Thanks for taking the time to read my Thread, its much appreciated!! I hope I can find a fix!!
PS: If anyone wanted to know what it looks like out of curiosity I posted 3 pictures with RED circle HIGHLIGHTING the problem when I try to touch something....
I really want to know this as well, because my phone is basically unusable at this state. I can get into it maybe 2 or 3 times a day, if i really try (locking and waking up the screen over and over until it becomes responsive). I don't want to buy a new digitizer if it isn't going to fix it, but i would gladly buy one if it will fix it. If you try it, and it does work for you, send me an email at [email protected] .
Anyone with any other information on this please help us out, there is a surprisingly small amount of info on this issue, considering how many phones were affected.
screen
I have read some threads on the power button being the cause. Try pressing it several times. Once you get the screen operating go to the market and get screen off app and a reboot app. Place them on your home screen toolbar. I use adw and it has an extra hidden toolbar if you swype down and then up on toolbar and up then down to close it. Either way you do it is fine. This keeps you from pushing the power button which has been discovered to be the problem. Hope this helps. I haven't had the problem, but seeing that it's happening more often I use these apps to keep from using power button unless needed to boot into magdlr.

Thanks for the help, yeah I havee seen that problem and I think that is my problem as well.... I am going to get a T5 Torx Screwdriver am pop open to see if I can maybe fiddle with the cable to get it to work again.... if it doesn't i might get a new digitizer or just have to go back to my old phone and save some money for a new smart phone
I have http://forum.xda-developers.com/showthread.php?t=933951 on my hd2 and theres an option in cynogenMod settings > input > long press home settings that lets you change the action that happens when holding down the home key. Just set that to "screen off."

Is my touchscreen dieing?

I was running an older Paramid version of dunphp's ROM, and right before swtching the ROM my touch screen start to not function. I could not pull the ring up to unlock the screen. I rebooted multiple times. Cleared Dalvik and fixed permissions. It finally worked after attemptiing to unlock it for what seem like abother 500 times.
I was going to change over to his latest Deisre HD ROM anyway. So I did a Task 29, and cleaned and reinstalled everything from scratch. It worked perfectly for about 5 days. Now I am getting the same issue with my touch screen. It just seems to go out. Is this typically what happens when it's about to die?
Never mind. I Task29, and flashed a Windows Mobile ROM just to see, and yeah...it's dead...

You have semi-dead digitizer. But it is nothing you can't temporarily fix every time it happens. Just push red (end call) button really hard for a while and it will get fixed for a while. I recommend you using button savior and lock screen with it and unlock with any other button than red one, it should be permanently fixed then. Please hit the thanks button if I helped you.

I hit the thanks button as you gave me hope. I am currently using my old TouchPro 2 with an old NRG Titanium Rom on it for the time being, but will try this today. I’ll install “button savior”, but what am I supposed to do with the app? What settings do I run? I think you are totally right about this, as I noticed when I was unlocking my phone, using the green call button worked most often, but now that’s not even working.

Yes, I have exactly the same problem as you have. My phone was working flawlessly for like a year and a half, but last week all of a sudden the touchscreen sometimes didn't work and sometimes it did. So I tried literally everything, I was fixing my permisions all the time, wiping dalvik, task29, remaking parrtitions, even bought a new sd card. But few days ago I found a solution, by pushing red button really hard (because the digitizer is right behind it) and not using it after. The Button Savior app is a simple app that makes a very little transparent icon on your screen and when you tap it, the menu of buttons will come up (with the same buttons as your hard buttons on your device) so every time you will want to lock the device you will do it on your screen, and won't have to push the hard button and come through all the hassle of pushing the digitizer. I really hope I helped you, as this very same problem was driving my crazy for the past few days.

Aww, that's a shame. I really tought it would help. It doesn't work every time, maybe you can try it few more times. If it's not even then going to work, then maybe you should get your digitizer replaced.

How long do you hold the red button? Also, I am pushing down really hard. I didn't know you could get the digitizer replaced...I wonder who would do that (no way would I send it to HTC and wait a month), and how much that costs...?
HTC sends phones back crazy quick. Atleast that's how it was for me. They actually sent it back the day they got it from what I remember. It did take a while though for the phone to arrive to HTC (this depend who and from where you send it though) If your phone still has warranty I seriously recommended you send it yo HTC. Just remember to flash it 100% stock before sending it.
Sent from my HD2 using XDA App
Well believe it or not, after pressing the Red phone off button for an eternity and applying a ton of pressure, it's working. I am sure it won't be for long. I have a shortcut to lock the phone on the screen. So basically your saying I should stay away from hitting the Red phone off button, or else that will kill it again? What about the other hard buttons?
I am in the UAE at present, so it might be better for me to just order a digitizer and do the repair myself. I see there are a lot of YouTube videos on the subject.
Thanks everyone for your help!

Power button behaving funny on Focus ...

My samsung Focus is about 1.5 years old.. I plan to switch carriers at the end my of contract since AT&T is giving me lots of dropped call at the new place we moved to.. The phone is obviously out of warranty, so I am looking to see if I can fix it myself.
The power button on my Samsung focus is behaving very funny lately. When I hit the power button with the phone awake, it thinks I did a "long press" of the power button and shows me the shutdown pull-down image! If I pull-up the image, the phone still reboots...
If I press the power button when the phone screen is OFF, instead of turning on the phone, it again shows the pull-down image, and the same behavior ensues - regardless of what direction I pull the image in, it shuts down the phone.
Some things I have already tried:
I have tried a hard-reset (camera+volume+power, and format the device), but the behavior continues.
I have removed my SD Card (I am using the AT&T approved one), performed hard reset, and problem continues
I have tried a different battery (from my wife's focus), and problem continues
At this point, I am guessing that most likely, the power button connector is loose.. but I am not 100% sure.. Any suggestions on things to try?
Seems like the spring in the power button is gone. I suggest when you want to press it, lean the phone to the right (with the power button towards the ground) so when you press it, gravity helps popping it back.
Or replace the power button.

Tried the first trick... didn't seem to help..
Any tips on where I can find a replacement power button and how I can replace it?
See my response here (and the thread referenced in my second reply). Seems to be one of the issues that appear in time... And in another case it was the battery...

I have ordered a new battery for now to see if it helps.. its a non-OEM battery off eBay.. Don't want to spend too much without knowing if that is indeed the problem..
I can't find a power button replacement part anywhere... I went over the video and the instructions to reach the power button housing does not seem very bad.. definitely do-able if I can find a replacement part..

The button itself is plastic (you can find some on ebay), and I don't know how it works, actually (If it's a spring or otherwise).
I suggest you watch a take apart guide and maybe, just maybe it's just dirt, which you can clean.
You'll know more and afterwards please share the result with us.

And now its completely gone... the power button won't respond at all.. the phone has been shut all day. If I take the battery out and put it back in, the SAMSUNG logo shows up for a few seconds and then the phone turns off again.. No way to turn it back ON using the power key..
I sat down to open the circuit yesterday only to realize that I don't have a #000 screwdriver... the smallest one I have is #00 which is too big for the 7 screws that hold the back panel
Off to Grainger today to see if I can find a 000 driver.. It can't get any worse now, so might as well open the phone!
Sure thing - I will update the post later with what I find...

You didn't say if the same happens with the wall charger connected.
Now, If you're going out, try and drop near a phone shop. Ask them if they can help you test with one of their batteries, either for a Focus i917 or from a Galaxy S i9000
Good luck mate.
Dang i thought i was the only one with this issue...
Mine started acting up about 3 weeks ago and it was seriously annoying especially when driving. I would press the lock button to change songs, but it thinks i did a long-press and does the "slide down to power off" thing. Even if i swipe up, the phone would switch off.
Then today, i take my phone out my pocket to send a text and find it's powered off. Won't even switch on now
Ender:
Plugging the phone in does NOTHING. The screen remains black.
Reinserting the battery causes the SAMSUNG logo to appear on-screen but again, goes black after 4-5 seconds.
Holding down the power/lock button has no effect, it's unresponsive.
I'm so pissed off this is happening 6 months before my contract is up. -_-
Don't know what else to say... I hope you still have warranty?

Not extended no... :/
I've managed to get it into "download mode" now though, and my laptop recognises it as "SAMSUNG CDMA Technologies"... Huh?
---------- Post added at 05:02 PM ---------- Previous post was at 04:45 PM ----------
If i have it plugged into my laptop,
hold vol down, power, and camera while inserting the battery i get to the hard reset screen. But then that disappears in the same 4-5 second window.
Ok, it's working again... I left the battery out for a few hours (literaly about 3), then pressed hard on the power button, and placed it (the battery) back in the phone.
Let it turn on and then back off by itself, then pressed hard on the power button.
pressed the button normally, and it booted up no issues. So far works fine.
I expect this issue is partly the power button, and something else unknown

Yes' same thing with wall power. New battery arrived and did not help. Went to a local cellphone repair and the guy said main board needs replacement.. he suggested to buy another phone since repair will be more expensive.. he said that he needs to remove soldering on the board reinforce an auxillary power button battery and resolder it in.. no guarantees and will cost atleast $150

Lucky you!! This seems like a common problem with several Samsung phones based on a quick google search
Also bummed that this happened with 6 months remaining ...Now I am somewhat stuck since I want to switch from AT&T due to call issues with several months remaining.. and dont want to buy one till wp8 is out...
Just for fun... I am going to find a 000 screwdriver and try to re-jig the power button.. nothing to loose with the phone refusing to start anyway!
For what it's worth, my power button had been getting increasingly creaky over the course of the last few months, and although not sticking, was requiring ever more pressure to operate. Also, the sound of rusty bedsprings every time I went to use my phone was getting somewhat embarrassing.
I found the sturdiest piece of paper that I could wedge in between the button and the rest of the phone, put a bit of PB Blaster on the paper, and wedged the paper in. The button has since been as good as the day I took the phone out of the box for a couple of months now.
*Edit: Should probably mention that the paper isn't supposed to stay in there - it was just used to apply the lube without soaking the phone.

So its working completely fine now? No issues? I'll try that but im not hopeful.
I've been having the same issue, started yesterday. There appears to be no issues with the actual button itself, it doesnt appear to get stuck or anything to cause this, even without the external shell and just compressing the sensor itself.
walletless, you said that you tried reformatting it and everything? Damn. I was expecting it to be a software issue. I'll mess with the button mechanism a bit and see if theres anything weird with it
Phone is dead
re-jigging and cleaning around power button did not help.. I ended up ordering a chinese knock-off of HTC Note instead
Does any have this problem, but on a normal stock rom?
I was thinking it might be just custom roms, I don't think that would have anything to do with it
Its worth a shot though

My phone died last month. I only installed updates that came through Zune up to 7.5. I went into AT&T and they told me too bad because it was out of warranty. I called Samsung, and they wanted me to 'volume down, camera, power' reset my phone, which didn't work. Samsung told me to send it to them for $70 because I was out of warranty.
Instead I entered a developer competition for a Lumia 800 and won. Now I just have a dead focus, and a new 800. I'd still be interested if anyone finds out a way to fix the focus problem.

Omnia 7 camera button issues

Hi all,
I've had an Omnia7 since launch and other than having issues with my headphone jack tripping the media controls on occasion, i've not had a problem.
Recently, however, when the camera button has become randomly unresponsive. That in itself is not too big a problem but last night it escalated from just being unresponsive to acting like the button was being pressed repeatedly when it wasn't being touched. In the middle of the night it woke itself up, went to the camera app from the lockscreen (as if the button had a long press) and started repeatedly taking very close up pictures of the surface it was sat on. Pressing the button all the way down stopped this happening, but the moment I let go it would start again. I eventually managed to stop it by repeatedly hitting the button with quite some force, though that isn't something I'd want to be doing regularly if it happens again.
It seems to be a hardware issue, but I thought I'd check if it was a known, fixable problem or is it a unique hardware failure?
I've had a similar issue with mine (sometimes would act like yours, other times to take a picture I had to put some strength on it). Solved it with electric contacts cleaning spray.
Ahh, fair enough, thanks for the info. Dirty contacts makes sense. I might get some spray and trying cleaning them.
I need to get the phone working again first though, as it decided to brick itself today. The battery ran out, I plugged it into my computer to charge and it booted to the screen with the nice diagram telling me to connect to a PC and Zune loaded on Windows saying it couldn't perform a restore. It just boots to that screen constantly now, which is a bit bizarre as I literally had done nothing with it for a couple of days. At least it had good timing dying 6 days after I bought a Lumia 920 rather than before.
Thanks for the information.
My Camera Button is not working anymore, it feels normal but does not do anything. I sprayed some CRC there but it did not do anything. I need to get to MAGLDR so I need the camera button.
Maybe internal contacts broken, try open the Phone is very simple just to reach the side buttons.

Back and Recent Capacitive buttons Not working, Home button is working fine!

Hi ,
I recently had a bad time getting our of the DFU mode, had to open the hand set, move things around and hoping to get through this all, now that the handset is alive again, the Back and Recent Capacitive buttons are not working, however the Home button is working fine.... I then proceeded to unlock the boot loader and loaded the Vortex rom but it still has not fixed my phone, so is this something which i screwed up during my dissembling of the phone or can this still be salvaged??

I think maybe on the side where the battery is resting. I'll have to go take a look again to confirm but I'm in a lecture at college right now so when I have time I'll come back and confirm it.

I think it hasn't got a dedicated connector, it might be the same connector as the screen. Maybe seeing JerryRigEverything's video would be better though

I'm not sure if Vortex ROM has this setup, however did you try the button swap in settings? I have seen this happen before with a teardown but haven't seen a solid solution.
