Exynos galaxy S7 black screen, no response at all - Samsung Galaxy S7 Questions and Answers

Hey everyone,
Making a post here in case someone has any idea wtf I can do with this.
My girlfriend's Galaxy S7 randomly seems to have bricked itself. She pulled it out of her pocket and the screen was black. Thinking it was crashed she tried power+vol down, but this did not work.
There's no activity at all from the phone - no haptic feedback, no LEDs at all. I tried connecting it to my laptop to see if it would come up there and nothing at all.
Things I've tried:
Vol down+power button
Connecting it to a laptop
Leaving it on the charger for a while
Trying to get it into recovery/download mode
I can't really think of anything else to try. Does anyone happen to have any ideas before we look at taking it to the repair shop?
Thanks so much!

Umm....I'd suggest your girlfriend stop telling lies, it's clearly been dropped in water. Everything you've described is consistent with water damage.

Wooow, no need to call my girlfriend a liar. Troll much? :/
She'll be buying a new phone herself and has no reason to lie. The phone also died in front of me and we're together most of the time, so thanks for being so helpful.
I actually think this may be down to the battery replacement we got done a couple of months ago now I think about it, so thanks for jumping to conclusions.

SOLVED!!! [Q] Help! Nexus S won't turn on!!! :(

Hi everyone.
Last night I went to bed and as usual I check my Nexus S battery.
It indicated me very low battery, and turn it off.
So far, no problem, i thought, well there isn't enough battery to turn on the phone. I connected the cellphone to the wall charger and went to sleep.
Today i woke up and try it to turn it on, the screens just flashes and nothing happens.... Removed battery, try it again, the same.
Try 100 times that, and there was one time a Warning of Bootloader came up. Don't know what i did different thought, but now i can't get the same result.
Actually now the screen doesn't even flashes when i press the power button.
The battery seems to be charged, i tested with a LED. My wall charger is also working cause it's able to charge my old phone.
And now to get things even worse, as i bought it in asia, i don't have warranty, and the gran finale, Nexus S is not been sold in Brazil due to some regulatory issues, so Samsung said it they can't help me with an imported product.
The Cellphone is brand new, doesn't have not even ONE month of use.
It's not rotted, and it was in the latest android firm.
Does anyone have any idea what can i do????
The phone doesn't respond to anything .
Tnks a lot in advance.

Is it showing full bars when you connect the charger and press the volume button?
dude, i think there is something wrong with our country. take a look at this thread: http://forum.xda-developers.com/showthread.php?t=1111761
i think you tried everything possible, can't see what else you could do. Looks like a hardware issue..
if i were you, i'd claim for warranty, even if you bought in hk, it has warranty, of course you will lose shipping cost, but, it's better than lose the phone! =o]
good luck!
GchildT: Nothing happens when i connect the charger to the cellphone.
Already tried the hard reset (volumn up + power button) nothing happens
thiagodark: Tell me about it, i read this thread ealier this morning, actually i send it a private message asking him if he solve his problem... samsung is really disappoint me.
The thing i found most said is that the phone is bran new! Not a month year old.
And i didn't do anything, not even rotted, dropped, anything!
PROBLEM SOOOOOOOOOOOLVED!!!
The problem was that there was a little tiny piece of plastic dirt in the usb male plug in the phone! And that piece was able to make a faulty contact with the charger, the phone battery was dead as hell.
Can you believe that?????
I almost sent my phone across the world in order to use the warranty.
Now I'm back with my cellphone up , happy as hell!
Tnks a lot, and remenber to always clean everything before use more drastic measures.

[Q] do you guys think its dead?

Hello guys, Long time lurker first time poster, I dropped my tablet last night and now it will not do anything, and i mean anything, no lights just a little vibration when I hold the power button for about 15 seconds. do you guys thing the MOBO is dead or just the screen and digitizer? I'm afraid the worst has happened and it is completely dead but i would like to get a few opinions first.
Thanks a lot guys, also I might have had one too many drinks before posting this so please excuse any nonsense, I've proofread this thing about 10 times so hopefully all is good.
It could be your connector for the screen came loose. If you have a HDMI cable, use it to hook it up to your tv, see if you can get anything to show.

Thanks but I tried checking the connector to the mobo and its a no go, I don't have an HDMI cable so i cant try that. when i hook it up to the pc it shows up as NVIDIA storage... something i forgot. it doesnt show as a tablet and even asus sync doesnt recognize it. do you think its dead for sure?
also my drunk self doesnt know what hes talking about as the drop happened last week i just got around to messing with it last night.
Thanks for the help.
Maybe your volume up button is stuck so posing power on poor it in APX mode?

Ok I just checked and disassembled as much as i could and nothing....i really hope its not completely dead but if it is its no big deal, i already have a nexus 7 so i might just buy a refurb 10" asus and use this one for spare parts.
Thanks a lot for your help btw

[Q] Suddenly, My Phone Will Not Power On

I've tried searching but no one seems to have this same issue. Or where I saw people with the same issue, they just stopped responding to suggestions and no resolution was reported. So if anyone can help me I'll definitely post until the end!
It started a couple days ago: my phone kept switching orientations (portrait/landscape) as if I were rotating the phone in my hands, but I wasn't. It would happen if it was being held upright, or even laying down on my desk.
Yesterday into this morning it got really bad. It would switch orientations literally every second. I started backing up as many apps as I could, but that was incredibly hard because the buttons moved every time the orientation rotated.
I was able to boot into recovery and make a data/system backup from there.
During the course of the day today my phone eventually just shut off. Now it will no longer power up. I have tried booting normally, as well as into recovery or download mode, but it responds to nothing. There is no screen flash; there is no vibrate. Absolutely no response.
I have swapped batteries with a friend who has the exact same phone. My battery works fine in his phone. His battery produces the same results in my phone: no response to anything.
When plugged in the phone behaves the same: no charging light, and unresponsive to any combination of button presses.
So... being that I'm rooted and likely out of warranty, is there any way I can fix this myself without going to Verizon?
Thanks a TON in advance to any replies! My fingers are crossed...
I've been seeing a lot of this (power button failures) lately. Are you on CM 10.2 by chance?

I was on AOKP Milestone 2, which I believe was based off of 10.2. I could be wrong, but it was either 10.2 or 10.1.
But this seems like a hardware failure, no? What would the ROM have to do with it? Not to come off as brash; just curious.

Haven't heard that phrase, but it certainly sounds like some kind of black magic

Try getting yourself a USB Jig off eBay or something or make one if you're crafty with electronics.
it should get you into download mode and then you can odin back to stock witch will atleast bring you a functioning phone
good luck
heres a video of the Jig getting this hardbricked s3 into download mode from the same Power on conditions you listed

Great find. Yeah he definitely has exactly the same symptoms as me. Although he bricked it by flashing things improperly. Mine just started out of nowhere.
Hopefully that makes no difference. I don't think I can wait for a "jig" to arrive. I'll probably try to make one myself. Anyone have one near Minneapolis that I could borrow for a few minutes?
I'll keep you all posted.
Well, good news and bad.
Good news: I made a jig. Bad news: it won't revive my dead phone. I tried the jig in an old S3 with a cracked screen and the jig puts that phone into download mode just fine. But nothing will wake up the other S3.
Could the micro USB port be damaged on my phone? What else could be causing this?

I honestly don't know what the Rom would have to do with it except two people before you described very similar things and happened to mention CM (recently, so I thought maybe a common thread).

Not sure. It was working for a couple months just fine on that ROM. This feels more like a hardware issue...
Being that the USB Jig didn't work, I'm not sure what options I have left. Anyone know how a JTAG works? Would that be an option?
Or am I just hosed?
it might be a faulty motherboard. its like something wrong with the actual gs3. that or your battery is dead. but if not its definately a hardware issue. try buying a new motherboard to exchange the bad one

N5 in bootloop - possible hardware fault related to power circuit

Hi guys
Unfortunatly my time has come to have a possible hardware issue.
Yesterday my N5 was connected via USB (like I usually leave it resting at work / charging) and out of the blue, rebooted. Google logo shows up, and reboots right away. Trying VolDown + Power shows up the menu but I hardly have any time to select bootloader or recovery, and when I do, it eventually reboots again after a couple seconds.
I'm able to turn it on and have it on if I avoid touching the power button, when I do, sometimes it works (screens just turns off), sometimes ir shuts down after a few seconds after doing so. It's not always, but happens three out of five times.
Connecting the USB cable has the same behaviour, sometimes it's alright and I'm able to copy files and so on, sometimes it shuts off and there it goes into bootloop again.
So, I got home, opened it and I looked like a donkey looking at a castle lol. I had a disconnected brown wire on the right side of the battery which I was able to fix, but that doesn't seem to be the cause of the problem.
The power button feels ok, it's not exactly rattled or anything, it has on/off feeling. if you know what I mean.
Problem is, I bought this in second hand in london about 6 months ago, would be hard to RMA and probably they would give me the finger.
Anyway, suggestions? Anyone went through anything like this? I doubt it's a software issue (rom) cause the same behaviour happens when on recovery / bootloader. Sometimes it holds on and lets me do things, sometimes it doesn't. Most often, doesn't.
Any help or tips are greatly appreciated.
Thanks guys.

I can't, was bought in second hand in a shop, besides I opened it and the water sensor is pinkish (never touched water, probably humidity).
I can only do that around christmas time.
Any other tip ? Something I can do before considering something like that?

By sending in for repair or replacement, I meant to LG. Not Google for RMA.
LG will charge you for the repair or replacement.
There really isn't much you can do otherwise.

s6 DEAD

My s6 died today out of the blue. I was checking some emails on my laptop and my s6 was right next to me. At some point i grab the phone to check something and the phone was DEAD! I tried to turn it on several times by holding the power button several seconds but nothing happened. I connected it to the charger and still nothing. The charging icon on the screen was not present. I called Samsung and after explaining what happened they told me to do the 30 second power button hold. Still nothing.... Then called the nearest Samsung service centre and they told me to bring the phone there for checking. Probably lost everything in the phone but good thing I got Onedrive activated and I do regular backups.
The phone is unrooted. Complete stock. All I had recently changed was the update to 5.1.1 and used Dark Material Design Theme. thats it. No water damage ever. The phone is completely unscratched and in mint condition.

Any thoughts over this? A workaround? Any help is welcome.
Thanks
Press and hold Volume Down and Power Button for at least 10 seconds to do a Soft reset. Also I've read of some people that somehow gets the Brightness to 0 and basically can't see anything or try to increase it, but that is different because you will notice that the phone is on, plus the led light and sounds are still working.
