I would try to restore a backup / flash a rom before thinking a hardware failure.

Well, simply don't, once is enough
Ok. But sometimes i press once but the phonecall still run on the backround,then i press again the red button and the screen become black...and then i hear the voise "hello-hello"from the person i was talking.that means that i cant bee sure that the phonecall stops.is this happens to you?is it any idea to fix the red button to stop the phonecalls only,and nothing alse?????
Thank you.
Nope, don't have that. And no it can't be changed, the red button is the one and only "power" key for the device.
Just use the onscreen hangup button...

Screen locked

I was playing a game on my Vibrant on my break earlier today and upon exiting it my screen locked up. Rather than wait for it, I pressed the power button to turn the screen off and went back to work.
A little later I brought it out to check the time and saw that the screen was on am pretty sure I saw that it said "Scanning media" at the top and assumed it had reset itself. A little bit after that I checked my phone again and saw the NoLed icon for new emails. I pressed the power button to turn on the screen and then tried to swipe it to unlock it but nothing happened.
That's pretty much where I am now. The volume and power buttons work but the screen is unresponsive (I can bring up the "Phone Options" screen but can't select any of the options) and none of the "soft" buttons on the bottom work either. Is my only option to do a hard reset?
And if it helps, this is a completely stock phone. Never been rooted.
I would just pull the battery.
I remember having something like that with NoLED, tr pressing the power button to wake it up and press the home key (unless you have it disabled in NoLED prefs) to get to the lock screen and unlock it.
Press and hold the power button until the phone reboots. That should take care of it.

Thanks! That did the trick. Could have sworn I tried that already but apparently I didn't hold it down long enough.

Where is the hang-up button?

I noticed this the other day, but figured it was just a fluke thing......I've now made about 10 calls on my OnePlus 2 and when I'm finished with my call, I don't have a hang-up button! I have to hit the home button, then swipe down and choose "Hang Up" from the little window there. Doing this is a quite a chore because the sensors detect when the phone is by your face and shuts off the screen, so when I try to touch my screen it will shut off the screen. I eventually get it, but it sometimes takes about 30-45 seconds to end my call doing it this way.
Am I missing something? Is one of the softkeys (on the phone) now the hang up button?
u have to press the dialer keys button and it will minimize and reveal the round, red end call button. yes, kind of strange. but u can also set your power button to be an end call button i believe.

Thanks!
But, something weird just happened.... I lost my "clear all recent's" and read if you boot into safe mode, that will fix it..... So I booted into safe mode and it fixed my missing "clear all" X......But it also seemed to have changed the behavior of my dialer??!!?! Now, I have the red hang-up button that shows all the time (like it should).
So it just sounds like it's a little buggy still?

Fast fast try to return it before Trump wins . He will build the wall you know... Jk...
For my opinion LCD has to be changed. Due drop or in your pocked from high pressure i think its gone ...
Since as you said phone is working you can take pictures or receive calls but screen is always black.
Can you see its black color or screen isn't turning at all.
Sent from my ONEPLUS A3003 using XDA-Developers mobile app
Mine started with green stripes allover the screen and few days later - "black screen"
Samsung change the whole unit.
But if lcd doesnt work so, it wont recognize when i press the screen, can it?
Anyone with this problem

S7 Edge BSoD Extra Info. needed
Hi,
Phone: I have a Samsung Galaxy S7 Edge SM-G935FD
I was using my phone to send a txt (and at the same time I think I was receiving a text or call because the menu and back touch buttons were lit up) and all of a sudden the phone crashed as I tried to finish my text but the touch wasnt responding, then the backlight turned of like it does if the phone is not being used. But the strange thing was that the menu and back touch buttons stayed lit up (Solid).
I tried many methods to restart the phone:
Power button + volume down (FAILED)
Power button + volume up (FAILED)
Power button + volume down + Home (FAILED)
Power button + volume up + Home (FAILED)
So I thought I'll let the battery die and then recharge and hopefully the phone would automatically restart like normal, however the phone does not show sign of charging now.
So I tried to connect to the PC but it wasn't being recognized however when I press and hold the power button a sound of detecting a device sounds and then when I take my finger off the sound of detaching occurs. But I couldn't see anything happening, until I went into device manager, under "Other Devices" , "Exynos8890" appears which I know is the chipset.
This is as much as I know of the problem. How do I solve thins problem without trying to factory reset the phone and lose all my data?
PS: I didn't backup my photos (My baby children only copies) or Notes in NotePad, which has some very important info.
