Phone not turning on using PowerButton...

I have a Samsung focus that I got used and is not turning on using the power button.
If I plug in the charger and wait for a few minutes then it turns on and everything works fine but once I completely turn the phone off I am not able to
turn the phone back on using the power-button.
Only way to turn the phone on is if I plug in the charger.
Anyone Have this problem?? or know how to fix?

same
Same here, started yesterday.
Also it turns off by pressing the pwr button instead of locking the screen.
Now i only can access download mode and magldr

Have you tried pulling the battery for a few minutes?

Yes I pulled the Battery out.

the power-button only works if it on. if its off completely it does not work.

The fact that the button will turn it off means the button provides the circuit closure required to trigger the toggle from on to off. Electrically, there is no fault. Time to flash a new ROM. http://forum.xda-developers.com/showthread.php?t=1528984 This one works really good.

[Q] Sudden Brick??

Heya, as you might've guessed my N4 doesn't turn on anymore
I rooted the phone this morning (didn't flash anything yet) and it was working all fine, until this evening I decided to go into Recovery mode. I turned the phone off and long pressed power button/volume down and it didn't turn on anymore.
The screen doesn't turn on at all, and there is no LED charging light either. I should mention battery must've been around 70% when I turned it off.
I got 2 theories: power button broke (possible?) or hard-brick (how come?).
Anyone got any idea? Any help would be reeeaally appreciated
EDIT: It's currently plugged in, but neither any LED notification is showing up and neither that large battery that usually pops up when charging with the phone off.

Lightflow, some other root only apps like Titanium backup.
Before I turned my phone off, I gave Solid Explorer root access.

Any help guys..? Is it even possible to sent the phone back to Google, and ask for a replacement?

Try holding the power button down for 10 seconds.

Well..I obviously tried that.
It doesn't boot up, doesn't go into fastboot mode either.
Is it possible to send the phone back? Since the phone doesn't even turn on, can they find out it was rooted?

Problem Solved A hard reset did the trick.
At this point I'm doubting if it was even hard-bricked in the first place

Is my phone done for? (Cant bot/charge/enter download mode/no response)

So few days ago my phone suddenly turned off and kept rebotting itself (It would reach the samsung galaxy logo and then turn off). I thought it was a battery issue so I removed it for 30mins and tried again, worked fine for an hour then problem started again. I left it over night to charge in the wall socket incase.
Same issue next morning and no solution.
I replaced the battery with a friends and the same issue happened on my phone (i used my battery on his and it works fine on his) so I removed the issue of battery itself.
That evening the phone then just stopped responding at all. It would not respond to pressing the power button (no load, no vibration).
Tried entering download mode using vol down + home + power. Nothing. (So cant use Odin)
Tried entering recovery mode using vol up + power. Nothing
Tried hard reset using vol up + power + home. Nothing.
(All the steps I used a fully charged battery from another s4 phone and removed/re-entered before trying again)
So I check online and notice some people having issues with power button, but even if that is the case - wouldn't my phone still charge? I dont even get the battery chargning icon on the screen when plugged in either PC or wall socket.
I opened it up and changed the motherboard with another samsung s4 and my original problem mobo still does not load on the new s4. (My new mobo worked on the old device though).
The ONLY response I got was when I used my original mobo on new s4 device and plugged it into PC, it popped connect and then disconnect sound and thats it (doesnt recognize usb port).
What are my options apart from getting another motherboard or going to a shop for a JTAG repair? I was contemplating just removing the power button and seeing if that helps in getting a charge response lol

Well your power button is broken for sure. Replace it and then test it.

Wouldn't the phone still recognize charging even if the power button is faulty?

It always takes a few seconds before it starts to charge. So maybe the device reboots before reaching the charging phase. I'm guessing though. But since your problems started with power button issues it would be the logic place to start.
The part only costs a few dollars.

Well I'm exactly in the same situation as you, since this morning on a i9505 running JFLTPE-GPE 5.0 ROM. The screen appears for 1 second or 2 (Samsung logo) then it powers off . I need to remove the battery to try something else.
Same behaviour, even for recovery mode, so Odin is not an option.
I thought that changing some kernel settings have caused that, but as I just put them back to default values, it should not happen.
I didn't have some power button issues, it was just powered off at my wake up this morning. In your case, does your phone vibrate and power up instantly when you put the battery ? That's the case for me, but it should not be the normal.

My problem is actually solved : indeed, it was the power button. I removed all the screws and played a little with this power button (air dust, etc...), enough to make it start correctly !
I managed to do some backups, and now I hope that it won't break again.

Yeah, that happened before (automatically powering up, vibrating, going to samsung logo and then shutting down and doing it again until I removed battery - putting the battery back in with start it up without pressing the power button).
When it was in that phase, the one thing that did work was doing a soft reset (home+power+down vol, and then holding just power) - however that only worked for like an hour before it went back to the restart phase.
However now it doesn't respond to anything at all. (Any kind of response I got was when I put that mobo in another s4 and plugged in usb, which just gave a connected/disconnect sound on w7, no life on the phone itself).
Be very careful as to what you do, I suggest you do NOT leave the battery on it and charge it (which was the last thing I did before it went unresponsive) - my guess is phone went haywire trying to turn on/off continously.

my OP2 Wont succesfully turn on, and I am all out of ideas.

Hello guys and gals i have a problem with my OP2. After i went on a walk in lets say 0 degrees celsius weather, it wont turn on again. As soon as I put in a power cable, it will try by itself and turn itself back on, but it fails because it shuts down again after a few seconds and it will go into a loop of trying to turn itself on and then fail. I have tried holding both power+volume button in, but it wont stay turned on long enough, for it to execute any of the commands in there. I am at my technical limits, and i hope that any of you out there, have had a similar problem or maybe a solution to my problem.

This is probably due to a faulty battery. Because even in case of a soft brick the device stays up for fastboot commands to work.
Maybe try the oneplus recovery software which formats everything and flashes the original firmware. Its in the general section of this forum.

Samsung Galaxy S7 Edge Not Turning On

Hi people.
So i'm having a problem with my S7 Edge and i don't think it is common. A few weeks back I was using my phone and it would suddenly turn off and the battery would be drained too. After this first incident with the problem it happened more often, and the phone would start doing boot loops to the point where the phone just froze and turned off. When these problems occured it will usually need to be a problem where I do a safe boot (Volume up, Home button and power key), and everything will be fine (or to charge it if the battery drained), but recently, the phone just didn't work at all, to the point I waited for the battery to drain (10 hours), and try charging it, nothing happens.
So firstly I was watching a video and checking my CPU/Battery tempretures to see if that was the problem (the tempretures at the time were around 31 degrees), and mid way through the video it bugged out through the audio in a high screech and turned itself off.
I tried turning it on again but no response to the screen, i tried safe booting it, or every alternative booting option, it did not work at all.
Here is all the diagnostics and repairs I did, but no luck:
- Tried turning it on
- Different boot options (Volume up/down, Home button & power key)
- Cleaning the port for moisture detection
- Replacing the battery for a new one (Genuine one)
- Doing all of the above, with it on charge
- Connecting to a PC, but no detection
One positive I found was that when i put the phone on a wireless station, it would change colour to show that the phone is charging. I have however took the wireless out of the phone as it was in the way of the battery, and safely in my draw.
Before this final fault happened, I did do a recovery to a previous Android version, just incase if it was a software fault, but it wasn't. The phone is not rooted and I had it since September of 2016.
Is there any alternative options to do? As i'm running out of ideas to do as every solution on the internet is to turn it on, which i can't whatsoever.
The warranty is voided also as there is a crack on the screen lens, and it's way too much to pay for a repair.
I need some explination of why this is happening, so I can go in the right direction and not to waste money if i was going to a repair service, or purchasing the parts for myself.
Any help would be highly appericiated.

Check your installed apps to see if there any viruses on your phone. All you said are signs that your phone might have a virus (check how to remove it here: https://www.unlockunit.com/blog/how-to-tell-if-your-phone-has-a-virus/
However, there is a chance that you do not have any viruses on your phone, but at least you have to isolate this possibility.
Did you recall installing any app prior to this behavior?

This may be the case, however i can't turn on the phone at all. I tried every possible reboot possible, download mode, bios mode, safe boot, reboot, but nothing happens unfortunately. Unless i can do it whilst it is turned off, i can do something. I have a PC if i can do anything else with it.
I don't think I have installed any weird apps on the phone.

sounds like a brick to me. Not a lot I can thing of you can do.
If you place the wireless card back in does it boot?
IT sounds like you've messed with the internals, so possible you damaged something?

I don't particularly think that I broke it from the inside as it was behaving the same before i opened it. And when i used the wireless charging, it will only indicate it was charging or getting detected on that charging pad and not on the phone regarding a red led, or the charging icon

Have you tried holding volume down + home + power for 15 seconds and try turning on the phone again?

As mentioned in the description, I have unfortunately
