Samsung Galaxy Epic display won't turn on... - Epic 4G Q&A, Help & Troubleshooting

I don't know what's wrong with my phone, but the screen display is messed up. Sometimes, the screen will display if I keep clicking the power button one-hundred times, but other than that it won't budge. Everything thing else works when I press the power button, the keyboard lights up, the home button and other buttons light, just not the screen. Like I said, I have to repeatedly press the power button so that in a slight chance, the screen might display.
I HATE THIS PHONE! What, do I do?

Need more info.
Can you access the recovery partition and it works fine? Access the recovery partition by powering on the device by holding down: Volume Down, Camera, and Power. Release when the hardware icons light up (down on the bottom: settings, home, back, search). You should see a menu appear after several seconds.
If the recovery partition does work fine have you tried a factory reset?
If it is still problematic within the recovery partition then it is more than likely a hardware issue. Possibly a problem with the power button?

[Q] Stuck at hboot - volume down button busted?

My htc desire is just over 2 years old. Out of warranty. Have not rooted or done anything else, just running the standard software.
A couple of months ago it got damp inside the pocket of my jacket. After turning it on it went to the hboot screen (the one where I can choose the options Fastboot, recovery, clear storage, simlock.) I dried the phone out and tried turning it on again.
Since then, whenever I have turned on my phone, it has had about a 50% chance of going to the hboot screen. Sometimes this screen would be unresponsive (ie. pressing the volume up/down buttons didn't do anything.) Sometimes I would be able to use the buttons to navigate around.
With a varied amount of removing the battery and mashing on the volume up/down buttons and power button when starting up the phone I could get it to start up. I think my success was related to half holding down volume up, so as to release the volume down button, and press power at the same time, but I'm not sure. This would sometimes happen after a couple of tries, but sometimes would take much longer, maybe half an hour of mashing.
Occasionally when running the phone would turn the volume all the way down to mute (as though the volume down button was being held, although I wasn't pressing anything.) Sometimes it would crash.
I took this to mean that my volume down button was busted, but things worked "ok" most of the time.
Today my phone will not respond to any amount of mushing the volume keys. I leapt into the deep end and disassembled my phone. I've pulled apart the volume button, removed the sticky black plastic that covers the circuitry of the button, removed the two small circular metal bits, removed the metal bar that is about 3cm long (1.5 in) and now the volume button is reduced to just a little bit plastic with copper bits printed on both sides.
I had hoped that this would be enough to completely disable my volume buttons and all would be well. Unfortunately... when I start the phone I am still at an unresponsive hboot screen
Does anyone have any advice that could help me? I could get the scissors out and start cutting stuff off but that seems like it would be unlikely to work...
Thanks in advance.
Wait...so you disabled the volume buttons, and you expect hboot to be responsive?
They were the only way to navigate through hboot.
What do you mean by "unresponsive"? Does the power button do something when pressing it?

Regularly, to get to hboot you hold volume down and the power button. My volume down button was permanently held down (I think,) so I hoped that by removing the volume buttons it would start normally.
By unresponsive I mean it goes to hboot but pressing the power button does nothing when I am there (ie. it doesn't select the highlighted option (fastboot))

[Q] power button automatically pressed

So I have my htc one x for a year now. Rooted and custom rom, all worked fine.
The keypresses of the power button will be simulated very fast with no actual pressure on the power button. So after some minutes off locking and waking my device I pressed volume down and power button. Now sometimes it simulates the volume down and power button.
So sometimes it shuts off the device.
So I opened the device and there appears to be nothing wrong with it. I turned my HOX on and quickly unplug the ribbon cable from the power button off. But the power button is still pressed really fast, like 2 times a second.
I can't even go into recovery to backup, restore or flash anything because it will press the power button really quick and after 10 seconds it turns itself off.
It happened before on Slimbean rom. But the problem went away after some days. Now i got MIUI and the problem is back. So I don't think it is rom related.
My solution:
Is there a way to disable hardware keys in the recovery? Then i can try to restore my official RUU nand..?

S4 mini with broken screen in download mode

Hello everyone,
I'm trying to rescue the contacts of a S4 mini with a completely broken screen (just black). I found some post stating:
First remove battery and reinsert, then press volume down, home and power button at once until the device vibrates, release and push volume up. Connect USB and flash the TWRP recovery with Odin. After removing/reinserting battery press volume up home and power. It should be in MTP mode.

As I can't see what happens on the phone I tried it several times but no luck. What happens is:
I press all the mentioned keys until it vibrates and when I release the buttons to press volume up, it vibrates again and a few seconds later the Samsung jingle is playing (I guess this is normal booting). Any idea, what I'm doing wrong?

depends what was causing your blank/black screen. If the cable has come loose then it will not work until it's reinserted.
What caused the black screen? Did you drop it?
Is there any sign of power in the screen? Is the black screen you mention caused by "no power" or "no image", do you think?
If no power seems to be getting to screen then you should take the back off and the inner cover and check the connectors, as first step. But could be other hardware failure (if not software).

A70 Screen Shot Info

I've got myself a Samsung A70. and after researching for ages how to do a screen shot or what ever the new name for it is.
I find out how to do this, you have to hold the power button then press the volume button, which then turns the volume up, 2nd attempt turns the volume down, 3rd attempt you try move your hands differently and you get a screen shot, of a different page you accidentally clicked on whilst trying to screen shot, then next attempt, I think I've got it, NO I don't want to turn the phone off, grrr. But eventually when you do get a screen shot, it has the volume change across the top.
Does anyone know how to alter the screen shot to the normal power button, the the central button on the bottom?

Mine doesn't work that way:
I press and hold the power button (no more than a 1 /2 second - you don't want the phone to display the power/restart options) then almost immediately press the VOLUME DOWN key for a 1/2 of a second at most (still holding the power button) and release the volume DOWN button - screenshot should be taken (screen shrinks/comes back). Release all buttons now of course.
Hope it works, let all know if it does.
:good:

You put your whole thumb on the power button and the vol down button and you click both of them at the same time.
Easier to click the buttons than swipe your hand across the screen.

Yep that's practically how every Samsung device works, infact every device I've owned, so it seems the issue is simply pilot error.
You can even do the same thing in TWRP.
What is TWRP.
I've had loads of other Samsung's phones been the power button and the main enter button on the bottom.
I've tried doing one first then the other and I get the power turn off option.
But them both with my thumb seems to work most of the time, cheers for that. I think the phone case I have causes me some problems, but both with my thumb seems to work for the last few mins that I've tried thanks.

You could always turn to the dark side and say "Hey Google, take a screenshot" LOL
Just press and hold both at the same time. If you are finding that awkward using your right thumb then use your index and middle finger on your left hand.

Question Black screen but still working. How to shutdown phone

Hi,
My Pixel 6 Pro screen went black, but I can still hear and feel that the phone is working. I used the volume up + power button to reboot it and now I touch the phone and I feel it vibrate as it's registering the touches. I also see at the bottom of the screen some white stripes flashing. It seems that the screen is damaged and I need a replacement screen.
Now my issue is that I can't seem to turn it off. As the screen is black, the only way to shut it down would be with hardware keys. But up until now, I haven't been able to figure out a way to turn the phone off.
Does anyone know how I can turn of the phone?
To replace the screen, obviously I need to turn it off first...
Usually long pressing the power button, but it may be different. As long as it gets fixed within a month or so it you can let it discharge until it auto shuts down. If more than a year old replacing the battery when repaired is a good idea anyway...
I tried long pressing the power button with no luck.
I tried volume down + power button for 20 seconds, didn't work either.
I tried volume up + power button for 20 seconds, this I think reboots the phone.

Power button only might take 20 or so seconds.
Otherwise just like it sit until repaired.
Power button + vol up + vol down. Keep holding down once you feel the phone vibrate. Takes you to the bootloader screen
The battery died.. so that's good!
Thanks anyways
