Galaxy s6 capacitive buttons not working - Galaxy S6 Q&A, Help & Troubleshooting

My galaxy s6's capacitive keys have stopped working. It was a gradually process. At first they became unresponsive and then completely died. The light doesn't work either. I have tested the lights with the app galaxy buttons 2 and set the lights to be always on, but they don't even turn on by doing that. I do not know if it has been dropped as I bought it from a seller on ebay. Although he did say the rear glass has been replaced as it broke so I assume it has been dropped. If anyone knows what i need to replace in the phone for capacitive buttons please say. Thanks

Could be the magnetic sensor. Is your compass working? Do you have an original flip cover available? I had issue with my S6 when the phone completely hanged when using flip cover due to the magnets in the cover. My capacitive buttons worked, but no light. It was a warranty case, and the dealer said it's a magnetic sensor failure.

[Q] Broken LCD and screen [GT-i9020T]

Hi,
I've broken my Nexus S. The screen is shattered and both the LCD and touch screen don't work. When I turn the phone on the bottom hardware buttons light up, there is the normal small vibration, however there is no display at all on the screen. The phone does seem to boot though.
Basically, I wanted to know whether buying and fitting a replacement screen, LCD and digitizer will fix the problem?
I have a friend who has replaced iPhone screen before and he seems to think that maybe it won't due to the screen not lighting up at all. Obviously I don't want to waste my money and buy a replacement screen for it not to actually work.
Thanks in advance!

Don't buy ElecShield screen protectors

Don't buy these

They break the proximity sensor (phone thinks it's near your head all the time). This is my experience, YMMV.
I guess you could cut a hole but it's bit of a PITA.
Mine are already on the way. What's the fit like excluding this problem?

They're a little on the small side but not too bad, I had mine fitted perfectly and it covers only the actual live area of the screen width wise, and is a little short of the top and bottom of the glass height wise, maybe 2 or 3mm.
I just did a little testing of the proximity sensor with my hand, without the protector on, and it seems that the proximity sensor only turns the screen off when the phone is vertical not when laying flat. Might test some more with the protector. I had to rip it off to end a call earlier!
Just done a bit more testing and indeed, hold the phone vertical while on a call and put the screen protector on, screen turns off, take it away, screen turns on. When the phone is flat the proximity sensor does nothing so if you put the phone flat while in a call you can access the keypad etc.

I spoke to an SGP UK agent on Tuesday. He said SGP are revising their design to allow for this. Said should have the new version sometime next week.
I have some cheap screen protectors that used to cover my SGS2 proximity sensors and had no problems, guess I'll report back when I get my phone ):
I have a BSE on order. I hope that doesn't do it :'(

If any protectors do cover it, a hole puncher should take care of it pretty easily. It may not result in the prettiest results, but it will get the job done until all of the manufacturers revise their designs to not cover it.
That works well enough for now

I bought from same seller in ebay, not a good fit (very short) and have proximity sensor issue as well.

Screen unresponsive, partially dead

So I've got a relatively cheap used sensation off ebay. It was announced defective and it was stated that part of the screen is dead. So I thought there were some dead pixels which didn't seem much of an issue for me. However, there are no dead pixels, the screen looks fine. However, it is very unresponsive. I have trouble pulling the ring to unlock the screen, selecting icons, typing, ect. There is also one part of the screen (one whole row) where the screen is completely unresponsive (doesn't react at all when touched).
Tried the SGS screen booster, tried cleaning the metal contacts on the battery side of the phone... nothing worked. The phone still has it's warranty seal, so it doesn't seem to have been opened..
Any suggestions other rhan faulty digitizer?
Thanks for your help
Sounds exactly like a faulty digitiser, which is costly to repair unfortunately, although it it surprisingly hard to break them, recently smashed the glass on mine, and the touch still worked perfectly!
I just asked the seller what made the touchscreen to stop responding. He said the phone fell off, hit the ground and afterwards the display wasn't working properly. Maybe there is some other way to fix this? The digitizer itself is not broken.. maybe there is something that got displaced.. or maybe there is a faulty connection somewhere on the pcb... do you have any suggestions? Thanks!
just noticed that if I squeeze the phone top to bottom (i.e. grab it with the thumb onto the unlocking latch for the back cover and the middle finger on top of the phone, just above the speaker) it opens 'messages'.. So maybe there is some bad connection on the pcb? Or should this definitely point to a faulty digitizer?

[Q] Proximity Sensor Busted LG G2. Workarounds please?

Hi I have bought an LG G2 D802 from eBay for practically nothing. The only thing that was wrong with it is that the screen had been replaced by what I presume is a cheap Chinese copy and after the replacement the screen would seem to turn off randomly (particularly during calls) and could not easily be turned back on again. Otherwise the phone works fine. The only thing that doesn't work is the proximity sensor. However I presume that this is a result of the new screen. Having read around on several forums, it seems that the proximity sensor is extremely sensitive to things like screen protectors, which can obstruct, or limit or prevent the functionality of the proximity sensor entirely. I therefore concluded that the likely issue was because the proximity sensor is likely to only respond to light over a given number of polarities (dark infra-red, placed against face, something similar I presume, in daylight or bright light, nearer the blue end of the spectrum etc). This would simplify how the proximity sensor should work under a number of given scenarios.
In the end the workaround was simple. I simply opened the phone and disconnected the proximity sensor and placed a small piece of insulating tape over the sensors connectors so it couldn't inadvertently reconnected when I closed the phone. The phone is now 100% fully functional, minus the proximity sensor of course. It now just functions like any other normal smartphone. I am naturally more than pleased with this outcome, given what I paid for the phone, which itself is in otherwise mint condition.
However the question I have is that the reason the proximity sensor was included was to prevent accidental button presses when making or receiving a call, when for example the phone is pressed against one's face. However it strikes me that exactly the same functionality should be possible in software? What I am looking for then is an app that will either lock the screen (or turn it off) to prevent accidental button presses in this way while a call is in progress and that will disable itself as soon as a call is ended. I of course need to be able to easily disable it, either from the lock screen, or via the power button, so that for example when I dial an automated dialling service and they want me to press buttons to navigate their menu I can still do this.
There seems to be a few apps around that can do this, but my question is, which is the best? Which is likely to cause the fewest problems for what I want?
I have ordered a new proximity sensor from China in case the proximity sensor itself might be at fault, but really having read that this can cause several problems and is rather more 'gimmicky' than practical, I think a software solution would probably be better anyway.
it should be replace with same hardware sir to be able for your device able to control it.
So has anyone found a fix for this problem aside from replacing the sensor itself? Maybe a build.prop or by using terminal. My phone screen wont stay on because it detects its in my pocket all the time posted screens below of useful info.

If you don't have the patience to read my story, skip to the solution at the end
Guys (and girls)!, I have found the solution, it took me like 6 hours to figure this out.
I have LS980 (LG G2 ofcourse).
I replaced the screen, and I actually refurbished the screen with LOCA glue myself, it is perfect, but apparently there's an issue with the proximity sensor, due to the specific shade they use to cover the inside of the glass at the location of the proximity sensor.
After replacing the screen, the Knock ON was not working, but KNOCK OFF was working fine.
In the Sensor Box i saw that i was getting half of the light that i was supposed to (on another LS980 i was getting about 800, while on the "faulty" one i was getting 400 light.)
And also the proximity sensor was dead, it showed 0.0 and a fallen plant.
I tried putting some tape, and colored it with a permanent market between the proximity sensor and the glass, and the KNOCK ON began to work, but during calls, the screen would not shut off.
I figured, there must be some SYNC between the light the screen is getting, and the proximity sensor, so i scraped off the paint that was on the glass where the proximity sensor is, so there will be much light coming in, and IT WORKED!!
SOLUTION:
Scrape off the dark paint on the glass (inside) at the location of the proximity sensor. do it gently.
clean it with alcohol so there will be no remains of paint.
don't be shy to press the Thanks button if this worked
Thank you work great

I just got my screen replaced, and this is happening to me. Is this something I can do myself?
My Fix
I apologize for bad english. If anyone knows SERBIAN and want to translate beter contact me.
Before you start to scrach the touch, try this.
On LG D-802 , the ruber thing on the proximity sensor was cousing me promblems. CUT the ruber only the part atached on the light sensor and proximity and turn it around. The big hole that was once on the light sensor(Ruber) comes on the proximity...
And that fixed my proximity. Now the light sensor is covered with the small hole on the ruber and the small amount of light is passing try that hole, try spreading it with heated something.
If questions PM me.
I think I am having the same problems with a G2. The digitizer on my girlfriend's phone broke so I replaced it with a digitizer/screen combo. No we can only turn the screen on (power button or knock) when there is a lot of light in the room. If it is dark, the screen will turn on for a second and then turn off. The screen doesn't go dark during a call either.
This problem didn't start until I installed the new screen. I scraped half the paint off but it didn't seem to make a different. I also don't have the screen completely sealed as I didn't have tape pre-cut for the shape of the phone. I wouldn't think that makes a difference but who knows.

notepro sleeps intermittently and then buttons are disabled

hi guys,
not sure if you're facing this issue.
i recently bought a protective cover, and after fixing it, noticed that the device is behaving odly.
it sleeps intermittently during use (as if you pressed the on/off button) and when you press on/off to turn it back, the home button and capacitive buttons are not functional. Back, home, and the task buttons can't work... after a few minutes of on/off, then it's ok.
however, when i take it out of the protective cover, it doesn't happen.
any of you have that problem?
Thanks.
Regards,
Liang
Yeah, I've experienced this problem too. I have a case that can flip the orientation of the screen. It seems that if I flip the tablet around the capacitive buttons come back. Very strange problem. I hope they can fix it in an update.

Hopefully the sensitivity of the magnetic sensor that controls smart cover functionality can be reduced via a software update. Until then being cognizant of it and realizing what orientation we have to keep our cover flaps away from to keep from triggering the screen off feature is all we can do.
Some cases have weaker magnets than others.

hi,
the cover i have does not have magnets.
where exactly the sensor that tirggers the sleep?
thanks.

The sensor is approximately 1.75 inches to the right of the G in the Samsung Logo and 1.5 inches from the top edge of the tablet.
Have you run a paper clip along all surfaces of the case/cover to determine for sure that there are no magnets embedded within either side of it? Magnets used for the on/off functionality in covers are thin and hidden inside the cardboard that is within the fabric/leather linings.

thanks... but what exactly am i looking at? or is it internal?
you reckon that it's the magnet that's causing this? funny, it was a cheap case, will run through a clip along the surface and check it out.
thanks
The sensor is internal. If you pass a magnet over that spot it will toggle the tablet screen on and off.
