I was having sporadic success when getting frozen in AROMA holding power + vol dn to reboot the phone.
Lo and behold I noticed (this behavior is repeatable) that if I hold the phone with the screen facing to the right side, it will reboot. Holding it facing leftward and it won't reboot. Very odd, and I am curious if it is like this for others as it is a handy tip if you don't have access to a PC and ADB to kick it back into the bootloader.
probably because your covering the light sensor. if the light sensor doesnt read any light it wont restart because it thinks its in a pocket or bag. its designed not to hard reboot or enter bootloader in your pocket

Hi there I just noticed that my phone will not turn it's screen on. Just when I press Home button or Power button them 2 touch buttons on bottom will start flashing and nothing else will happend. Even after taking battery off for few minutes and restarting phone doesn't help. After restarting phone screen will just blink for split second and then stays black! Phone was working on just few hours ago and wasn't touch since then just untill now. This is stock GT-I9505 updated with Kies few days ago. Did anybody heard about something like that before? Can't connect to Kies now as screen needs to be unlocked for this. Please help as I don't know what to do!
You could try download mode to see if you get any display there and it may also be worth checking the user accessible stuff (sim/take out sd card/check sockets for foreign objects etc) but I would start looking at getting it replaced under warranty.
cheers
Removed both sim and sd card with no joy. How to get to download mode? as I've tried all those ways:
FIRST METHOD (easiest/most common)
1) Power phone off
2) Plug USB into computer
3) Hold vol up + vol down
4) Plug USB into phone while still holding the vol up and vol down
5) Yellow /_\ (triangle, Downloading, Andy shoveling, Do not turn off Target!!! symbol)
Your now in Download mode
SECOND METHOD
1) Power phone off
2) Plug USB into Computer
3) Plug microUSB into phone
4) Hold pwr + vol up + vol down
5) When Batt icon goes away, release pwr, still holding vol up + vol down
6) Yellow /_\ (triangle, Downloading, Andy shoveling, Do not turn off Target!!! symbol)
You should now be in Download mode.
THIRD METHOD
1) Power phone off
2) Pull battery out
3) Hold vol up + vol down
4) While holding vol up + vol down, plug in USB cable into the phone
5) While still holding vol up + vol down, put battery back in
6) Yellow /_\ (triangle, Downloading, Andy shoveling, Do not turn off Target!!! symbol)
You should now be in Download mode.
and this one as well:
How to get into Download Mode (eg: for Odin)
Unplug the USB cable.
Shut down the phone.
Hold down the 'HOME' + 'VOLUME DOWN' buttons and press the 'POWER' button for about 2 seconds until a WARNING! Screen appears. Press the 'VOLUME UP' button to enter Download Mode.
To get out of Download Mode, simply press and hold the power button until the phone restarts.
Screen still stays black. I forgot to say that when turning it on it vibrates as normal and after I remove battery for 10-15 sec and put it back again and then turn phone back on screen just flick for split second but not at whole area only part of it - different part every time I try this

I think you'd rather get it repaired or replaced. It seems the display is dead.
That's what I'm afraid will have to be done. Just hard to stay without it just a week after getting it from store
Haven't you heard? Once you go black you never go back.

I had the same problem, what I did was went to youtube and try to disassembled the phone.
-Checked to make sure everything is in the right place
-Took off all of the components and leave the motherboard by itself
-Heat up the motherboard with blow dryer for sometime until it get hot (not wayy too hot)
-Put the battery back on (don't screw drive anything back yet)
-Try to power up
-To make sure it works properly, lightly flicks on to every places on the side of the phone and screen.
-Put everything back on gently and done
Reflow soldering using home tools of any kind is, at best, a crapshoot. Using an oven, as some people recommend, runs the risk of melting plastic components if you turn the heat up too much. Plus the temperatures these people recommend are too low to melt the solder completely, which is what you want in reflow work. A hair dryer is a better idea than the oven since you can direct the heat. However, a lot of the heat generated by the hair dryer doesn't actually blow onto what you're trying to fix. The hair dryer also suffers from not being able to put out sufficient heat to melt solder completely. The best of the home solutions without spending tons of money on a solder reflow station, is a heat gun. Even the most basic heat gun puts out sufficient heat to melt solder completely, plus the heat is concentrated on a small area, which is what you want. I would know, as the laptop I'm typing this on was repaired twice. The first time using the oven method, and the second time using a heat gun.
Prior to purchasing the heat gun, I had tried baking my laptop's motherboard in the oven at 385 degrees F (196 degrees C) for ten minutes. The fix worked, for about a month. The problem was that the recommended temperature was too low to melt solder. Lead-free solder, which is used in most electronics worldwide, melts around 217 degrees C (422 degrees F). While I could have tried again at the higher setting, there is a risk of the plastic components on the motherboard melting, so I had to try something else.
I considered the hair dryer, but after doing a little research determined that the hair dryer just didn't have what it takes to get the job done. I bought the heat gun instead. To reflow my laptop GPU for example, I had to make sure all components except the GPU were covered in aluminum foil. I then held the gun one inch (2.54cm) above the chip and turned it on, holding it steady. After letting the gun run for a minute I shut it off and waited twenty minutes for the board to cool.
As of now, the heat gun repair has lasted longer than the oven repair. Hopefully I can get another year out of the laptop before getting a replacement. But, regardless of how the reflow work is done, there is no guarantee as to how long the repair will actually last. For some people, it doesn't work at all. Some people may get a month or two, like I did with the oven reflow. Some lucky individuals may actually have the repair last essentially forever. But when you're out of warranty and the repair service wants to charge an arm and a leg, what do you really have to lose?
I'm taking a look at my coworker's Nexus 7 (non-3G model), and it's exhibiting some peculiar symptoms. The most obvious is that the power button was jammed - I popped off the back cover and took care of that. The button has an extremely soft touch now, but it seems to work fine.
It was also booting itself up in safe mode. I figured the jammed power button was causing some weird power cycling, and the filesystem had been corrupted in some way. No sweat, just flash the 4.4.4 factory image.
Still booting in safe mode every time. If I turn it on with power + volume down, I get the usual bootloader menu, and all three hardware buttons work for navigating the menu. Then I continue past the bootloader and get into Android, and it's in safe mode, and the volume down button doesn't seem to respond (though power and volume up work).
Rebooting the device with the ribbon cable for the power/volume buttons disconnected from the motherboard still lands it in safe mode. So I'm pretty sure it's not a stuck hardware button.
For good measure, I flashed TWRP, fully formatted all the partitions, and reflashed again. Same deal. Now I'm running out of ideas. Does the N7 have some kind of auxiliary volume button inputs somewhere that are jammed/shorted, and which the bootloader doesn't look at, but Android does? This is what I see in adb logcat:
Code:
I/WindowManager( 483): SAFE MODE ENABLED (menu=-1 s=-1 dpad=-1 trackball=-1)
I can upload the whole logcat somewhere if anybody is curious/bored enough to look at it. I couldn't find any interesting errors in it, though.
Guys I was yesterday turned off the phone, now turns and reaches the black background with logo of Samsung Galaxy S4, then restarts, will not let me enter recovery mode, and if I enter download mode, gives me the option of pressing button increase or decrease volume and pressing any of these resets and returns to the above.

What can I do?
Your power button may be stuck.
when pressed, it feels normal

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; )

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.
My S10 Plus's volume panel is stuck on my screen with two of them also being greyed out. The device will not power off as the panel blocks the power off icon. Holding the power button to turn off also doesn't work. What the actual F?
can you connect it to a computer and adb reboot? Then uninstall whatever you installed to break your phone!
I had the same problem and fixed via a hard reset by holding down the power and volume up button at the same time. The phone resets and voila problem solved
