having this problem with my phone too, i cant even get it to stay on the settings screen long enough to back up my stuff

edit: well i think i solved it. i tried clearing the cache, didnt work. then i did a hard reset, didnt work. then i went back and cleared the cache and did a hard reset at the same time and it seems to have worked.
[Galaxy S6 Q&A, Help & Troubleshooting] seiferflo:
+1 same problem. It happens mainly when the phone is on the move. Funny thing it happened 3-4 times while taking the metro (go figure) with the data on. Usually when I turn off the data, it reduces the amount of back press.

Normal reset doesn't solve the problem. It stops after a while, probably when the phone cools down. I can't seem to reproduce it, but I believe it has something to do with the data on.

I don't really want to factory reset so I'm going to write to samsung directly as the phone is brand new.

Did anyone try loading a custom rom and got it fixed ?
[Galaxy S6 Q&A, Help & Troubleshooting] Robi-K:
I've had that issue with my first one. Took it back ASAP as it was DOA. Got a brand new one 3 days later as they didn't have any in stock. This one doesn't have any problems. Don't worry to mutch about it. Get it exchanged.
[Galaxy S6 Q&A, Help & Troubleshooting] faiding:
It is a hardware defect: When the phone turns up power to the radio to strengthen the connection, it can cause Electronic Noise to leak over the connection into the capacitive buttons (due to poorly insulated shielding tape), causing the phone to think the buttons were pressed. That's why you notice the problem more when roaming -- the device needs to be repaired/replaced.
[Galaxy S6 Q&A, Help & Troubleshooting] yoavmatia:
I have the exact same problem...did anyone contact the manufacturer and got a response on the matter?
[Galaxy S6 Q&A, Help & Troubleshooting] pickles523:
I believe it may be an app setting messing with the system settings. My device did it once and wouldnt allow me to use my device. After factory reset it made it worse so i used twrp and wiped everything but my modem and flashed my stock firmware and it stopped and hasnt done it since
[Galaxy S6 Q&A, Help & Troubleshooting] seiferflo:
Hum that's interesting, thanks for your precious input on this.

I did contact Samsung who asked me to do a factory reset. It didn't change anything.

They redirected me to a Samsung office in Paris, not for repair but for a deeper factory reset... (not sure what they are talking about), but I haven't been there since due to lack of time.

However, I didn't experience the problem since the last update FXXU3QOKN so I'm keeping an eye on it.

Following "faiding's" comment, I'll probably pay them a visit for a replacement.
[Galaxy S6 Q&A, Help & Troubleshooting] yoavmatia:
working "workaround"

workaround:

lower the speaker volume to ~75% in all settings (Media, ringtone, system, notifications, etc...)

Whats going on? why is it working?

some posts ago someone (user called "faiding") mentioned something about EMC leak, or at least he meant to, by mentioning a faulty insulation.

with that in mind i did some testing and found out that the closes radiating component it the speaker... and once you lower its emissions even thought the faulty insulation, the EMC leak is sufficiently low and the 'capacity short' is avoided.

Note: depending on how 'faulty' is your insulation (it varies from one phone to another depending on production line assembly) lower the volume until the issue stops accruing.

not full-proof but working :)

Repair tech

It is true that if your in the US and your phone has no damage or any water damage to void your warranty even if you bought it from someone else, u can register the phone at samsung website and then request a repair. It will still have a warranty.

But as I am a Cellphone tech, sometimes I rebuild phones. A s6 came into my shop and i once rebuilt it and worked for a while before doing the phantom touches on task and back keys. So when i pulled the screen up a little off the touch keys, it would stop. I gave up after a while trying to figure it out as i had more things to work on. Back in December i decided to rebuild it again, new screen, new battery, new frame and new back. Turned it into a gold s6 to try and sell it again. Sold it couple days ago, and it came back the next day doing the same thing. So got bored tonight and started to take it back apart. Figured i would try one more thing, replaced the charging port (which is also the soft touch keys) to see if that would resolve it. So far its not wigging out but im letting it sit here and try using it from time to time, with wifi on and a simcard installed. So far its not going crazy, but I will let everyone know if it fixes it or not. As for the "Youtube thing" I tried that, did not resolve. Im guessing its a defective soft touch keys/charging port.

I would not recommend this repair unless your phone is out or voided of warranty.
[Galaxy S6 Q&A, Help & Troubleshooting] Fabianmarcelo:
Hi dslayer83,

I've the same problem with my S6

Could you solved the problem replacing the charging port?

It would be very important to me knowing how to repair the phone because I buyed it abroad. In my country Samsung does not cover warranty.
[Galaxy S6 Q&A, Help & Troubleshooting] Tiennetti:
Up with this thread!

I had an S6 since January.. initially the problem was very random, maybe 1 or 2 times per day, sometimes would go crazy for a while

Then i had some time with no defect at all (a couple of weeks?) without doing nothing

This past week, the phone was feeling like the MENU button (what menu as in this phone there isn't any?) and that was very weird!

Today, it simply went completely crazy, and now is completely unusable... i can't actually swtich it off as the back key is pressed so quickly i don't have the chance of doing nothing!

EDIT: Managed to reboot and wipe cache... now it is useable, but still hits the button from time to time
[Galaxy S6 Q&A, Help & Troubleshooting] Tiennetti:
Update... went unuseable again today.... factory resetting now...

If it works, shall we suspect is something software related?

Update: Not working... it started giving the phantom touches just after the factory reset then suddenly stopped

Worked fine for few hours, then started craza again

Now i have done a wipe and factory reset again, and still unuseable
[Galaxy S6 Q&A, Help & Troubleshooting] Fabianmarcelo:
Hi Tiennetti,

The hard reset doesn´t solve the problem, I've tried it twice. I'm sure it must be a hardware problem, but I don´t know of wich component.
[Galaxy S6 Q&A, Help & Troubleshooting] jackjsnyder:
I have a Galaxy Note 3 and the back button has been going off on its own. I have been having the issue since I received my "new" (refurbished) phone with my Asurion warranty. I tried many different things.

Then I noticed something...

It was only happening when the back button was lit for any reason.

This is what fixed the issue for my Galaxy Note 3. Perhaps it will work for the S6?

Settings -> Display -> Touch Key Light Duration << switch it to "Always off" >>

Now my menu and back button no longer light up (but still work) and the issue is fixed. (The back button no longer goes off on its own.) It's been stable for hours now though and it was constant before.

I will repost if this "fix" stops working and it starts spamming again.

Like I said my phone is a Galaxy Note 3 not a S6. I hope that this helps S6 users too.

Cheers!

After many tries, the phone has been working flawlessly since yesterday morning (and without doing anything special)

So now that I was decided to send it to repair, the problem is solved....:eek:

I tried this before, and didn't solved the problem, but i'll keep an eye on it

[Galaxy S6 Q&A, Help & Troubleshooting] YellowSmiely:
Typing *#2663# into the numpad and updating everything bar wifi temporarily fixes the issue but a factory reset does the job permanently. Sent my phone off to Samsung and that is what they did... same issue again though; after half a year. I thought it was some App I installed but after not downloading much, after initial fix, I can confirm this is not the case unless it is a Samsung/Android bloatware issue. Some people say it is a static build up due to a non official charger but I only charge mine on an official Samsung charger...
[Galaxy S6 Q&A, Help & Troubleshooting] Tiennetti:
So, from 17th of April the phone worked perfectly until a couple of days ago... then started "backing" again

I haven't done anything special, still i was installing apps one by one but didn't appear after the install or usage of a particular app

WIFI fix done, no success... Factory reset done, no success

I just hope it lasts like this until monday when i can go to Samsung assistance

I had this problem a couple of months ago. It was fine and now has returned. I didnt know what happened last time but was fixed. This time i tried everything thing....hard reset, turn off and tons of features, chace sims, *#2663 , clean screen , colling the fhone in the freezer (yes i tried that) etc..so far it keep lighting the keys and returning. I suspect of several things...can be something to do with big Samsung updates...till the release a smal hot fix to reduce key or screen sensitivity or whatever. Can be static cuz recently the phone passed on airpor tray sec machine and i got a small discharge when i pick it up...can also be somethkng to do with batery charging cycles...i rly dont have a clue. If someone know the fix let me know pls :)

Update

I think i found cause and solution :)

I remembered ive used a spray cleaning solution (recommend for electronic devices) and a cloth to clean my phone display.

Since its pulverised when I sprayed the screen maybe some moister got inside via home button. So I put my phone with a LOW heat lamp bulb near the touch keys/ home button for 2 hours. After 3 long days the problem is now gone. It was probably moisture inside the home button/touchkeys causing it to randomly malfunction.

( by the way Be vry carefull with the heat you apply or else you could end up with some melted component/screen or damage to fingerprint sensor).

Just wanted to share this with you guys, hope its works for you :)) have a nice day

[Galaxy S6 Q&A, Help & Troubleshooting] mumineq:
I got the same issue, but I noticed that it only comes up when the phone is connected over 2G network (Edge). With a 3G or HSDPA connection (I have no LTE) everything works fine. So another workaround is to disable your 2G network in the settings: Mobile networks -> Network mode -> select "3G only".

I have been trying with the original and 3rd party chargers, doing resets, doing the TSP Update but it always comes back on a 2G network.

[Galaxy S6 Q&A, Help & Troubleshooting] koragg97:
Is it possible that a bad battery may be at fault? I'm a S5 user and my capacitive buttons keep pressing themselves randomly. Short and long presses (kills apps...). So one minute phone's alright, the next it starts killing apps and isn't usable. I tried the suggestions in this topic but all the same. Even if i disable the capacitive buttons through the system files (and enable soft ones), the phone still clicks them as if they are not disabled. Idk what's going on but my battery did give signs of dying right before this issue came. Phone turned off on 9% battery, said battery temp was 90C and kept telling me my phone's overheating although it was cool as an ice cream :/ I'd greatly appreciate any help at all as this is starting to get ridiculous.

PS Can you believe it? I wrote this whole message from my phone and it didn't kill my browser (this time).
[Galaxy S6 Q&A, Help & Troubleshooting] Tori88nz:
How I fixed this problem...

I had this problem quite bad I couldn't even send a txt without it going back to home screen. I turned off wifi and mobile data this seemed to help a little. I then went to settings, select more on the top right hand corner and select system settings, scroll down til you see ANT radio and select it, then disable. After that it should all be fixed and you can turn wifi and mobile data back on. :)

one solution

I had the same problem with my S6, ive not read this entire thread so this may already have been posted. Tried factory reset, reinstalling ROM and uninstalling a few things (the phone is rooted so i thought it might be something to do with that). I used the 'All in one gesture' app to disable the back buttin which made the phone usable again. however, one of the many threads i found said something about a build up of static causing the issue, sounded plausible. I bought a new genuine samsung fast charger, fully discharged the battery and recharged a couple of times and it has solved the issue. been a couple of days, all good. ill post if it changes!
[Galaxy S6 Q&A, Help & Troubleshooting] Cat229:
I came here yesterday, because suddenly I had this problem and my phone went crazy. Tried all the things above but nothing worked. I turned my phone off (never do that) and went to bed. This morning I turned on my phone and got several messages from Google that someone had used my password (scarry, because I had a good one) and tried to login to my account. Google blocked the attempt, because it was done in Boston and I live in the Netherlands. I changed my passwords and kicked of Messenger from my phone and now I don't have the back-button- thing anymore!
[Galaxy S6 Q&A, Help & Troubleshooting] Kneggarn:
For me it generally occurs when the charger is connected, so my guess is faulty electronic shielding in the device or something to that effect. Replacement would be my best guess for a solution.

[Galaxy S6 Q&A, Help & Troubleshooting] SnoopNL:
So this issue started rising for me as well.

3rd s6 in 1.5 years btw and after this, I am surely done with Samsung.

However, noticing the issue arose while I kept using the same chargers and cables I couldn't figure it out until 2 days ago.

In my car I use a quickcharge 2.0 charger and the cable shielding near the connector was broken.

Since I've replaced the charging cable in the car the issue has not returned yet.

Before I would use the *#2336# method and use all 3 options from top to bottom, and on the reboot following, I would clear the cache partition.

But it seems for me the issue came from a faulty cable shielding.

Still believe the phone is a piece of crap, if even a USB cable shield breach can mess it up totally.
[Galaxy S6 Q&A, Help & Troubleshooting] danielxx48:
Solved!!

Hi, I tried all the solution i found on internet, but none of this worked... I solved by installing this app " button remapper " search in playstore

It work without root, just install it, now you have 2 alternatives in my opinion : 1. use double options with "recent apps key" , setting 0,25 seconds for" function back" and 0,5 for "function recent apps" disabling the back button, so you use only recent apps button for 2 imput.

2. Simply change the press time for the back button from 0,25 to 0,5. So you will press the back button twice as long but the self pressing will not be heard... I hope this solves the problem permanently.

Brothers button remapper is really working for that problem . Its a complete solution of this problem.
[Galaxy S6 Q&A, Help & Troubleshooting] drevildevil:
Work around

Have had the same issue with S906L, but with the recent apps menu button. Especially if I tapped on the back glass cover or bottom corners it would vibrate like I had just picked it up randomly. (the power noise self test would fail 50% of the time) Reset, update touchfw, cache clear... nothing worked.

What I ended up doing was root, then used AIO Gestures from the playstore. Disabled menu button, and remapped it to long press on the home button. Decent work around.. This seems to be a hardware issue for me, possibly needs better shielding across the capacitive keys, but as soon as there a Nougat ROM compatible with the SM-S906L , will see if that makes a difference. And if not, might open it up and use some foil shielding to see if the radio is indeed affecting the keys.

Sorry, its been a year since ive been on xda and didnt realize i had someone asking a question. Yes i did resolve my issue as it was the button shorting its self out.

[Galaxy S6 Q&A, Help & Troubleshooting] S6Paul:
My phone had this problem for a few days. I couldn't even send a text the phantom back pressing was so persistent. An ATT rep recommended I factory reset it. I did so, but the problem continued unchanged. I brought the phone with me to work today and charged it powered off from about 2% to full using the OEM charger and cable. At home I had been using for the past several days a generic cable connected to a laptop to charge. Since I charged it with the OEM charger and turned it back on a few hours ago, I haven't had the problem. This is a surprising improvement. I'll post again in a few days. - S6PAUL

And reset it's setting, deleted my cache blah blah

N now it's 100% fixed

No back spam

I used for 2 straight hours (wasn't easy)

Use multiple apps like YouTube, camera, Google etc to the point it heated up like literally it's burning my hand right now
