I'm not sure how this is possible, but about once or twice a day, the back button on my S6 is pressed on it's own. It has happened when the device has been on the desk, I see the soft keys light up, the device vibrates like they've been touched and the app I was on went back, all while I was not even touching the device.
It's happened mostly when I'm holding the phone but not even close to touching the buttons, and once it happened and pressed the back button about 10 times in a row while I watched it.
The phone is completely undamaged, perfect condition, never touched water, not dirty at all, buttons are 100% clean. Happens while it's charging or on battery.
Has anyone else experienced this?
(My device was repaired by Samsung for a different issue, motherboard replaced, this only started happening after the repair)
i have, started like yours random. then it started happening more and more so when i was at the store waiting for someone i decided to factory reset ( factory reset twice while at the store) but it got worse. couldn't even get passed initial setup the phone just kept spamming back button so i just kept going back. luckily i already ordered a replacement s6 from tmobile since i was having some other issue with the phone. sadly the replacement s6 took over 7 days to get here. shipped through UPS and got to hawaii then for some reason UPS gave it to USPS for delivery. kinda sad that i ordered screen protectors 2 days after i ordered replacement phone and the screen protectors got here 4 days later through USPS. but other than that my NEW ( we all know its refurbished) galaxy s6 so far has no issues. even the no audio on calls is fixed.
also if you are going to order a replacement, be sure to let them know you have a GALAXY S6 and the date it was released. i say this because the 2 tmobile reps i talked to kept asking questions they say it was for them to determine if my galaxy s6 that was what 2 almost 3 months old at the time was still under warranty
My s6 was showing the same issue with the stuck back button.
It started randomly but than it went crazy and stuck. I wasn't even able to use it.
But 1 factory reset fixed it.
But yesterday the random stuck back button started again when the phone was on my desk and it was really hot (weather was hot as well as the phone). I turned it off for a while and apparently the issue stopped.
I'm not sure it's temperature, firmware, whatever related but I really don't want to factory reset it again.
No solution here, but it is happening to me as well
Solved
Hi i had the same problem aswell , i bought samsung s6 in Pakistan, after the update the back button kept pressing ghostly, i went to local samsung repair shop and the assistant reset something from the setting and then it was fine, i even asked him what you did and how you did? but he said it is secret lol very stupid. i could have post the solution if i know it, but i think it is very easy and something to do with setting. i am sure it is not hard/soft reset. i will post this on other forums to help other people.
thanks
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.
+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.
i am having same issue too.

Did anyone try loading a custom rom and got it fixed ?
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.
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.
I have the exact same problem...did anyone contact the manufacturer and got a response on the matter?
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

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.
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
What worked for me is turn power saving on

might be a coincidence, but this worked for me:

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.

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.
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
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
Hi guys!
I bought one of those LG G Flex 2 H950 @ US$249 on eBay from Qualitycellz. However, my unit seems to have some issues...
It does not matter what I am doing on my phone, does not matter whether I am using a SIM-card or not (I tried the phone with and without Sim-Card), my phone keeps rebooting on various situations, meaning that there is no pattern or logic on those restarts. Usually I am just casually using my LG G Flex 2 and bang, the phone restarts. I can't find any meaning at all. I have looked it up but I could not find anyone with a similar issue, nor a solution.
What makes it even more crazy is the fact that I have tried numerous factory resets, as well as installing a new ROM! (I have installed the H950PR 5.1.1 ROM over the 5.0.2 AT&T one), however the phone is still not working properly. I could swear the problem was the ROM, but it looks like it is not.
What can I do about it?! I live overseas so returning the phone to get a new one is not an option, and warranty for LG is not international :crying:
Thank you and best regards.
The phone has a hardware defect most likely. I had this problem with my G2 a few months after I purchased it. Regardless of temp or ROM the phone would reboot all the time.

I see. And how did you solve the problem in the end?
If this is really a hardware problem, I am helpless, I guess...since I am not in the United States right now.

It was never resolved, actually got worse ha-ha. Sometime in Aug or July it stopped going into the OS so I started disassembling it out of frustration. Also linked the wrong post.

Exact same issue
I also bought an lg g flex 2 from ebay user qualitycellz. I also do not live in the US. My phone started doing these resets and it got to the point at which it gave up and just wont start... (It tries and tries again until i plug it in or it runs out of charge). There seems to be something dodgy with the seller and I will be emailing him regarding the issue.
Chiming in here, same issue, same ebay seller. Any updates from you guys?

Same issue here. To turn device back on I have to hit the power and the volume down. If I upgrade to marshmallow will it fix the issue?
My phone reboots when i use 4G, i now only use 3G to avoid any problem, but that's annoying
To bump my previous post, I talked to LG, they claimed a motherboard problem and will be replacing it under warranty.
Same problem here

I too had this same problem for past 2 month's.It all started with the mobile restarting randomly ..2 days ago it stopped to boot up at all.:crying:
It just keeps bootlopping on the LG screen .turns off and again LG.
When I try to use it plugged in ,it works a but slower than normal.
I think it is a hardware issue.maybe with the battery?Guess only ?
Anyone here has a solution ?I am currently outside us .:crying:
I have the same issue with my Flex -2 purchased from same seller last year August.
I also bought an lg g flex 2 from ebay user qualitycellz. I also do not live in the US. My phone started doing these resets for last 4 days. It tries and tries again until i plug it in and press power button. If I disconnect from the wall, it stopped working. But since yesterday it got to the point at which it gave up and just wont start. I see only the LG screen flashing. If I press the power buton

You'll have to send it in. It's a hardware bootloop problem. Only LG can fix it unfortunately.

I have changed battery. No more problem with randomly reboot.
Lg flex 2 restarting problem
I tried a lot of things but now i am sure this is a battery problem ,i noticed that when i charge my phone to 100 percent it started normally so every time i charge it all the way to 100 percent it works and when i dont it just restarts so you have 2 options to replace the battery or charge your phone fully every time
Hope this one helped
My G flex 2 also started doing the same. Seller was also the same qualitycellz from ebay.
My flex2 also started random reboots. Once mainboard was changed because there was bootloop issue, but now its a bit different. Also a bit over one year with a new board.. Maybe the reason of it is battery because its quite old. well, I need to wipe it clean just in case.

Haha... Your story is exactly as mine. The random rebooting got worse for me over the span of a week and now it reboots after a second of staring up. So it's basically bricked.:crying:
My Nexus 5 died on me.
A few days ago, I woke up and connected my phone to the charger and went on with my daily routines. And when I checked the phone after half an hour, the phone was completely off. I tried to turn it on and tried all the key combinations, the phone showed no response at all; no Google logo, no bootloader, no TWRP, the screen was just completely off. I thought that it was the battery's fault as the phone was almost 2 years old and had been showing signs of depreciation. It doesn't even show anything even when I connect it to the charger, instead it heats up a lot during charging. So I took it to the service centre and the guys at the service centre told me that the motherboard had got fried and the only solution is to get a new mobo which costs 13,500 INR (200$). But, I don't want to spend that much fixing this device, I think its better to buy a new phone. I am planning to get something cheaper than the Nexus 5 with a not bad specification and good dev support (thinking about Moto G 3 and OPX).
Three of my friends also had bad experience with the Nexus 5.
One friend had the same issue, the phone died one day without any apparent reason. He is now using a YU Yuphoria.
The other two friends' phones just started bootlooping one day. Both those phones were not even rooted ( not the power button issue, they also had to replace the motherboards, but luckily their devices were under warranty back then, so they got it replaced for free). I think LG used cheap low quality components to make the Nexus 5.
What do you guys think could have caused this problem?
I had the same issue. I received a Nexus Device from a friend with a faulty wireless card. I know it was faulty because when I could get it turned on, it would never turn the WiFi adapter on.
What I did to fix it was, I ordered a broken Nexus off ebay. The screen was cracked and the guy tried replacing it but he f'd up the internals somehow. I swapped out the mother board which was easy and flashes stock Marshmallow and haven't had any problems since.

But that's just a small issue compared to mine :/.
Still a sign of cheap components.

Same thing would fix yours. If you buy one with a broken screen then just swap motherboard it would be cheaper than buying a mb replacement. I have the opposite issue with my wife's G2, motherboard is ok, but everything else, screen, battery, toast.
At first starting to use a new charger the phone would have the screen go black in the charge was low, but now it keeps on rebooting.
The phone allows me to enter the Android system recovery but even after a factory reset the phone will continue to act in this manner.
No OS updates were applied prior to this and the device is still locked and hasn't been tampered with.
I'd really appreciate it if I could get some help with this.
Exactly the same happened to me 2 days ago,i cant get pass the LG logo,even if i can it will restart after 1 minute of use. I sent it to service for repair. Reinstalling OS might help at some point,but if it keeps restarting like mine i dont think its possible,but if you can access recovery then do it. I will give info after i get it back. If you wanna do that,just download LG UP and kdz somewhere from xda,you can get it on xda easily.
We have that issue discussed in Q&A session. There's two possible root cause. Easier one is caused by the controller chip on the battery gone crazy. That one can fix easily by replacing the battery. The more unfortunate ones have got issue with the CPU Chip Solders disconnected. (G4 users also faced that issue quite a lot). For those ones, there's no way but to replace the whole circuit board. Someone suggested about baking (yes, baking the chip in the oven) and let the solder reflow to reconnect. But no one tried it yet. (Linus TechTip tries on a dead Nvidia Graphic Card and it works, but beware that the phone circuit boards are more delicate than the PC graphic cards).
My Lg G Flex2 h950 is having similar problem. I cant get pass the LG logo. It just keeps restarting. How can I solve this?
I recently bought a LG G5 used. Perfect condition upon arrival, except for the Google lock. I'm taking care of the lock. My issue is the screen. I had it on trying to figure out the lock when my battery died. At this point my screen was fully functional. I plugged it in while powered off and exactly 50% was black, the other exact 50% was a collection of randomly generated colored pixels, looked like white noise from an old tv. I unplugged it, plugged it back in and now I get black screen. In a dark setting when plugging in the device I can visibly see the screen energize to black for a second then turn off again. Phone still charges fine. The LED turns on, phone still powers on like normal but no screen. This sounds like a software issue, but I really don't know. Now I'm consulting you, the xda people for help.
I'm having issues with my G5 as well but it's unrelated to your issue however while looking for a fix for mine I did see a view things about the issue you are having. I believe it because the GPU of the device has failed and the only fix is a motherboard replacement, unfortunately.

Yeah I saw this video on youtube:
Its not a G5 but a different LG but the problem looks to be the same as you described.
The LG G5 "half screen static" issue is one i've personally experienced. From what I could debug, this is an overheating issue with the system board. For proof, put the phone in a freezer to let its core temp drop down. After a while take it out of the freezer and surprise! The screen now works fine, proving the overheating issue (until the system warms up and screen starts glitching again).
Some videos on the net have talked you can fix this by opening the phone and putting new thermal paste on the sys chips area. I've done it all and the issue still persists (others have reported success), so any other advice would be appreciated.
I ended up buying another G5 on the cheap and have the other for spare parts in case.
Here are two videos that talk about the specific issue you experience, the other talks more about the paste

I do have a motherboard on it's way, and anyone looking for a motherboard for your LG G5 BEWARE! Double check your g5 for it's model number (mine is located inside the device under the motherboard for whatever reason). There are 9 variants of the G5, mine is LG LS992. I will reassemble my g5 and try the freezer trick, update on that later.
Do let us know if the freezer trick makes the screen work again, it seems this overheating issue has appeared over several LG G5 variants (mine was H830).

The freezer trick did not work, put it in a 0⁰ freezer at work for 30 minutes and nothing. My notification led still works and so does the vibrator so it's still just the screen. And also I bought a motherboard for a VS987 while mine was LS992. They look exactly the same, and I studied each one. And no the vs motherboard didn't work. I'll have to send this one back and reorder the right one.
5 stars to LG for designing a really easy to repair phone, minus 1 star for intentional life stunting, minus 1 star for generating 9 versions of the g5, and minus a star for hiding your model no and imei IN the phone requiring disassembly and a screwdriver to read.
