Crashing Issue with SM- G930W8 - Samsung Galaxy S7 Questions and Answers

Let me start this off by saying that I've never rooted/jail broken before, but honestly I don't know what else I'm supposed to do right now.
Since about last Saturday, my S7 has been crashing. It's extremely hard to replicate, as it can/will happen during anything. Opening an app, crash. Using an app, crash. Get a notification, crash. Reboot after crashing, crash.
I took it Rogers and because of a small crack I have on the screen they refused to help me out. I took it a mobile repair shop and they said they could help me out for $300. They also said something about it possibly being an issue with the motherboard from being dropped, which was two weeks ago, (It didn't freeze or lag at all until last week) which would warrant the hefty price tag.
Problem is, I'm not exactly in a place where I can just throw down $300 to fix my phone. I was just wondering if maybe anyone here had any idea what the issue might be, and if it's worth trying to root it or just scrounging the money together to pay it off.
I'm sorry if this isn't the right place to post this, but I'm at my wit's end here.
Thanks in advance.

First step would be to clear the cache partition from recovery
If that doesn't help, factory reset the phone
If that doesn't help, flash stock using CSC to reset afetr the flash
And if that still doesn't help, it could be a hardware problem like they say from the drop

S6 Pressing Back Button By It's self (Capacitive key)

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
possible fix
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

Nexus 5 water damage - screen's all black - motherboard related?

Hello guys,**
Well few days ago I accidentally dropped my Nexus 5 in a glass of water for just 1 sec. So I immediately switched it off and wait a bit to let dry then restarted it, and all seemed to work fine. But just some days later and up to now the phone boots up all fine as usual to the lock screen, and from there I can pull down the notification bar (and navigate through it, activate/deactivate wifi, etc..) but when I unlock it to get to the home screen it becomes all back and nothing appears on the screen even though the phone is still on.*
It's really confusing and weird. When I call the phone it rings (so no signal or sound problem) but I can't still access the screen to take the call as it's all back and unresponsive.
Following some suggestions I disassembled the phone and cleaned it dry but same results again! So now I think the problem is somehow related to the motherboard, coz as you might notice on some of the pictures attached, it seems that some plastic parts have melt down to cover other smaller parts. Anyway guys,*I'm just wondering if some of you guys had experienced something like that and if you were luckier*to find a solution or any directives that could help. Or you even think that's a motherboard problem like, do you know any ways to fix that o buy a new one somewhere??
PLEASE!!
Sorry apparently, I can't publish links until I get like 10 posts or plus..
But anyway guys, I'd really appreciate your help.
Why did you power it on and short circuit it on purpose for??
Bump
@SekouCheikh
Maybe it's a coincidence that you dropped it in water and this happened a few days later. Once in a blue moon mine does something similar to this (although not usually as start up only after lots of use), but I think it's related to an app or xposed. I only notice it after installing a bunch of crap again. Maybe try a factory reset (do it though the computer) just to see if it is somehow not hardware related? That's what I would try first.
Help please

Wait... Are you seriously posting from 2 different accounts??
<...>
First, simply try to factory reset or flash a new rom. There is not enough evidence to be sure it's a hardware problem, it could just as well be a coincidence that it started happening just now.

Hi guys, I'm sincerely apologizing if this is the wrong place to open a thread about something like that, I couldn't figure out where else to write down my issue. I've been told here are people that know the most about devices and that someone might be able to solve an issue I got with my Samsung s6 Edge. The samsung support has been not helpful at all and it's either sending it to them to repair it and loose all my files or at least before doing that at least trying to save some of my personal files. The problem yet is that I can't even get into my phone. I was charging it at night and suddenly I saw a flashing Samsung Logo on screen with a blue LED that flashes as well. So the device had to be turned itself off and then it was restarting but it couldn't get pass the 2nd SAMSUNG loading Screen and got stuck. That's all. From then on I wasn't able to do anything with it. First I thought it may be making some updates, but then again I turned off my wifi before going to sleep. So that can't be the case. I waited hours, because I was hoping it might get pass it at some point but it didn't. While waiting I looked up tutorial to fix it but nothing seemed to work out and then I called the samsung support which basically just told me to turn it on and off without any real solving advice. So here I am. desperate to just save up the last photos and that's it. Does anyone know a solution that won't mess with my guarantee.
Again, I'm really sorry if this isn't the right place to ask.
Thanks for reading if you made it up to here,

You may get more help by getting the thread moved to Galaxy S6 Edge Q&A, Help & Troubleshooting.
To do so, simply click the "report button" and select "thread/post moving".
Now, on with the issue. What you're having seems to be a bootloop.
One thing you could try is booting into recovery and wiping the cache.
I'm not exactly sure how booting to recovery works on the S6, but it generally is: turn the phone off, then hold the power button + volume up button until the phone vibrates. If that doesn't work, try adding the home button to that combo, or just Google how to boot into recovery.
Anyway, if that doesn't work, then I'm afraid there won't be any other solution than reinstalling the firmware yourself or sending it to warranty (where they will probably reinstall the firmware).
Your photos shouldn't be affected in the process, as they are saved on the internal memory and, unless somebody wipes it, you shouldn't lose your files.
But you will definitely lose your apps and app data in the process.
Flashing the firmware yourself should not void the warranty.
The process can be done with Odin (a software also used by Samsung). I'm not sure how familiar you are with flashing, but you may want to do some reading or watch video guides on the subject of using Odin. Since the S6 is pretty much a new device, I'm sure you will find lots of video tutorials for the S6 specifically.
And, as I said, your internal storage stuff should be safe too.

Google pixel keeps crashing and restarting. What should I do?

I was watching a video on my pixel when suddenly the display freezed and turned off. Since then it has been restarting and crashing again and again. I have already done factory reset. I am unable to attach image here which would have given a better idea of the problem ibb. co/ jDdU6b . Remove the spaces in the link to see the photo.
Instead of a factory reset have you tried flashing the factory image via fastboot? I would attempt to backup what is important and run the flash_all.bat with the file unaltered. This will allow the image to be flashed and all user data would be wiped giving a clean install.

Just for humor, it is the same concept!! https://youtu.be/kKAjay0iWwI
Bro, let me know what you find out because this ****ing phone has got me sick and tired of these reboots. It just ****ing reboots at random times and even when it boots up after a reboot it will freeze and reboot again. Honestly, I have never said this to anyone because I am a hardcore nexus user but **** this phone, google really ****ed this one up.
I been having this issue, and preformed a factory reset on Jan 1. I cant say I have seen it re-appear. I am 7.1.2 by the way. If it is across the board with 8 and 7.1.2, then it may be some wonky google app that is common to both. It was not any specific application that it happened on either.
I just did an RMA, my warranty ended in dec 27 and they still sent me a new one. I hope the new one doesn't have problems, it probably is a google app.
Return it before your warranty runs out. This happened to me on december 15th. My warranty expired nov 17th and google refused to do anything and ubreakitifixit cannot fix it. This is a known issue, but google won’t stand behind their product. Eventually your phone will shut down and never turn back on.

I wanted to update this as it is possible I might have stumbled across something.
After wiping it and restoring some apps, I had no issues with it until the week of the 22nd of January. I installed one app and it started to reboot randomly. That app was Android Pay. Once it started to happen I uninstalled it, and have not had any re-boots since again.
Best Regards
This just started happening to my girlfriend's pixel. Bone stock, never rooted. If you even have a HINT that your phone is rebooting for no reason, I suggest you send it in for repair as soon as possible. Her phone now just bootloops, and you can't boot recovery mode either.
Google support said that the warranty expired in October, and so they told me I can go pound sand.
Well I can call UbreakiFix... I got a quote of ~$500 to replace the motherboard + screen, and no one else sells it that I can find.
A flagship phone lasting barely more than a year is not acceptable to me. Google should be offering me a replacement device, and I'm rather pissed that they aren't.

Yeah man same thing just happened to me, like wtf
Same here. Just bootlooping... Thanks google
This is what I get for updating my damn phone, Same problem here.
Now happening yet again to my Pixel and this is the 3rd handset I've had in 18 months. Now need to send this back to Google so that'll make 4 Pixels I'll have had before my contract ends and I can escape to a handset that works.
This problem seems to be pretty widespread. Mine Pixel’s been doing this for a while now - sometimes it’ll go days without me at least noticing a reboot, other times it will happen so often as to make the phone useless. I just tried a factory reset - anyone know if there’s a permanent fix to this? It sucks when I’m in the middle of a call and then all of a sudden the phone shuts down and starts rebooting.

OnePlus Nord - System lags every time after paying with phone

Hello there,
I have rather strange issue with my device and id like to ask if anyone else is expiriencing this same behaviour or maybe do know how to fix it.
So i bought this phone about 2 weaks ago. The first weak everything was working like a clockwork. No lags, no reboots needed, excelent battery life. But for last 2 or 3 days I am facing really weird system ?bug?. Basicly anytime i use my phone to pay in shops or public transportation the system starts to lag as crazy... The payment does go through without a problem but just as the google pay screen should pop up on the screen of the phone the phone just freezes in a really weird way. (I can lock it using a power button and the display does go off, but the allways on display doesnt go on and clicking the power button again to unlock the device does nothing. - I am basicly in the situation where i need to hard reset the device in order to continue using it.)
It happened to me once even without paying so i dont think that it is the Google Pay app thats at fault but paying with my device causes the issue everytime.
It is really annoying and i am starting considering returning the phone for a refund and switching to the new Nord 2 as i am still eligible for it. But as a last resort before i do that i want to ask you if someone does know why this is happening and can help me. Other than that i really like the device very much.
