my screen turns off when disconected from the charger - Samsung Galaxy S7 Edge Questions and Answers

i left my phone charging with a game playing, and when i came back the message saying the phone was going to turn down to stop the heat was showing in screen.
now when i turn on the screen it takes 1 second to turns off by itself and start overheating below the samsung logo(in the front, below the earpiece).
i can fix it or have to replace something?

Could try booting in safe mode. That should rule out any hardware issues.
Instructions from Google:
Turn the device off.Press and hold the Power key past the Samsung Galaxy S7 edge screen.
When "SAMSUNG" appears on the screen, release the Power key.
Immediately after releasing the Power key, press and hold the Volume down key.
Leave in this mode for a while. Maybe uninstall the game while your in safe mode.
I had a similar issue I solved this way.

Black Screen, 5 vibrates, and LED lights on

This phone just broke after 3 months of use. Since I brought it off of amazon as unlocked, I do not have warranty on phone. The phone was not dropped nor water-damaged. It was sitting on the table and suddenly experiencing problems with lag. I proceed to turn off and try to restart phone.
The phone does not boot when I press the power button.
What I've tried:
case 1: I removed SD card, removed battery and removed USB cord. Press power button for 10 seconds. Put back battery and press power button
result 1: LED light on. The phone vibrates 5 times. Remains in black screen
case 2: I called my phone number from another phone
result 2: Straight to voice mail. This indicates the software did not even boot up. Hardware display is not the issue here. Most likely a Software issue.
case 3: I hold volume down key and power key to attempt hard-reset
result 3: LED light on. The phone vibrates 5 times. Remains in black screen
Since I routinely backed up my phone data. Last time I've checked (~4 days ago), the SD card was not nearly full. It was approximately 25% used space.
PLEASE HELP!! YOUR HELP WILL BE APPRECIATED!
Are you able to access any of the service menu's such as bootloader or fastboot mode?
If your not aware what those are, there are many references in this forum for you to find information.

No. The screen was all black. But fortunately, the phone was able to turn on after some trial and error.
You remove the battery and USB cord. Then while pressing (and holding) the home button key, you put back in the battery and press the power button. To hard reset, you must press volume down key, home key, and power key at the same time.
Glad that you got your phone working!
Mine continues to remain dead
I had this problem a few months back at first i too thought the phone was dead - but it did make boot vibration noise - but the screen would always remain "black" but after some time and after going into a very dark room i was able to see that the screen was not black, but that the backlight went out on it -- after having my screen replaced the phone now works fine - think i was using cm7 at the time.. hope this might help
Thanks for this tip! I'll check on the phone I had as well. I got to get it back from my buddy.

Won't charge

I did a search and nothing was answered other than to try the whole "power off device via bootloader and BAM problem solved"...which doesn't work for me. I also have some issues not discussed. It seemed easier to just start a new thread.
So my wife let my N7 completely die. So she goes to charge it and it won't charge. She tries another cable and those don't work either. So here is what happens, and what I've tried so far. Also, I am rooted running CM10.1 I believe.
1- push the power button:
Up in the top left corner i get the text "show low low battery icon!" device turns off after about 3 seconds.
2- plug in charger:
When I do this, the little battery charging this comes on and the battery fills 3 times then the screen goes off (about 10 seconds)
3- hold power button for 30 seconds
if the charger is plugged in-> it brings up the battery w/lighting bolt, then says Google, then shows Cyanogen mod boot animation, then loads up my home screen, then instantly powers off because of no battery (0%). then starts all over and will repeat indefinitely (given that i continue to hold the power button down.)
charger not plugged in-> shows battery icon, says Google, then CM10 boot animation, then loads home-screen, then powers off, repeat indefinitely
4-if i take out charger after putting charger in:
it will still show the battery charging sequence for the ~10 seconds even though no charger is in
5- with charger in, pressing power and volume down:
takes me to boot-loader with the android laying on its back with its torso open. it says information in bottom left corner. it says start up in the top right by the power button, then has an up/down arrow by corresponding volume keys. Pressing volume keys does nothing. pressing power does nothing. I can hold the power button and it will restart, says Google, play CM boot animation, load home screen then power off.
6-without charger, pressing power and volume down:
see object 5
7- press power while charger connected.
Tablet loads with the whole Google->boot animation-> home-screen. while on the home screen, device starts powering off (0%) battery. while this is happening I can press the power button again to bring up the power menu. I can power off or restart:
a) power off: turns off device. nothing changes
b) restart-> boot-loader: restarts into boot-loader. see item 5
c) restart->recovery: tablet restarts, but then just goes to a black screen and then turns off. (sometimes it will also do a "normal" restart and load back to home-screen and what not)
d) restart->restart: restarts tablet normally back to where it will turn off immediately.
It does all of these things consistently. I am not sure what exactly I should do to try and fix this. any help would be greatly appreciated.
Thanks.

[Q] Trouble turning on - need help desperately :)

Hi guys. So this is my situation; my phone is currently turned off.
If I hold the power button, the Samsung Galaxy S4 logo appears in with the black background, then disappears and the phone turns off after 1~2 seconds.
If I hold the power, volume down button then I get the custom OS screen. If I then choose to restart from this screen, the phone restarts and the Galaxy Logo shows for around 6-8 seconds then disappears again.
If I go to the custom OS screen again, then press restart, I can then hold the volume up button and the lock button and the blue message saying 'Recovery Booting..' along with the same black Galaxy logo then the screen disappears after 1-2 seconds seemingly turning off, then it vibrates once after a couple more seconds then does nothing again
I can not get the recovery booting screen from simply holding Volume up and the power button, I need to do it after restarting through the custom OS screen.
My phone is also suddenly not recognising the charger being plugged in. There is no observed difference between attempts to turn it on with/without the charger plugged in.
The last time the phone was properly turned on, it switched itself off at around 4-6% battery left and from then on I have this result.
So, can you guys help?
Your power button is probably faulty. Try to wiggle it lose or replace it.

Galaxy s4 turn off with a slight touch of power button

My phone will a shut off with a slight touch of the power button. A gentle touch of the power button would bring up the shut off, restore, airplane mode option then would turn off the phone. when it shuts off on it own, when trying to turn on the phone the "samsung galaxy s4" logo show but then it shuts off again. i replace the battery already so i narrow it down the power button. please help this is super annoying.

It just "feels" normal.
Try tapping it on a hard surface for a while..not too hard tapping though..
It should be fine. Happens with many here
could it be because the place you battery latches only
I just remove the phone to see if the buttons are locked, and there were none in this condition
I believe there are 3 connections on the motherboard for the power button. Do you have a multimeter to see if the power button circuits are constantly open or closed?
I opened it and pulled the internal button on and off and was constantly rebooting, I took a technical service and changed the internal button now works well; )
