power button stuck on "on"

Since yesterday my SGS is having a very strange issue: It seems that the power button is stuck on pressed state. When the phone was on I had the power menu appear and the phone shut down. Then it started again, only to turn off shortly after the second screen during boot, then looping in that state.
When I remove battery and put it back it automatically starts and then bootloops.
I can't get into recovery as it turns off before recovery can start. I can get into download mode but only for 3-4 seconds till the phone turns off again.
I removed the backplate and can't see any visible damage to the power button. Between the power buttons pins on the board there's a voltage of 7mv with battery removed, in case that means something to anyone.
So 2 questions arise:
- Any ideas on how to fix this? (apart from ripping of the power button which I'm not even sure would help)
- Any ideas how to get into a mode where I can backup my data or at least flash a stock rom? (Currently on CM9 with devil kernel and the devil logo shows for a second in the bootloop, not sure how the techs would like that if I was to sent it in for repair)

Has there been any water damage to the phone/button? Sometimes this can cause the button to short. Or it might just be stuck, does the button physically click in as normal?
It could also be worse and have an actual hardware issue with the motherboard/power button interface

there hasn't been any water damage. actually, it's been used in the rain but that shouldn't really hurt a phone... just in case i let it try for quite a while but the problem didn't go away.
the button clicks as it used to do, no sound of water or damage there.
problem hardly could have been worse as the phone is completly unusable in this state as i can't even turn it on.

Hi,
A friend has just handed me an abandoned SGS with precisely the same problem.
The power button itself feels fine, ie it doesn't feel stuck, and you can feel it clicking as normal. I too removed the backplate and can't see any visible damage to the power button.
I note however that the water damage indicator 'sticker' mentioned here: "samsunggalaxysforums.com/showthread.php/4674-Galaxy-S-I9000-Service-Manual-How-To-disassemble-your-Galaxy-S"
is completely white, indicating possible water damage at some point.
Any ideas for a fix, or do you think it would be economical to seek a fix from a hardware repairer?
I can replicate the problem as described by XlAfbk above, by simply holding down the power button on my working i9000.

i did sent to phone to the only service location samsung lists for germany. they claimed it was water damage and refused to repair under warranty. repair would have cost ~280 euro.
i'm waiting for the unrepaired device now and will try to fix it myself, in the meantime i got a gnexus

Ok thanks. Please keep me posted if you do find a way to repair it yourself.
Until then, I guess mine's spare parts!

no more warranty for you? if you're in germany PM me for a repair shop.
ebay has power button replacements for ~4€ that you could try soldering on, replacing the original one, if that's what's broken for you. I checked mine with a multimeter and as there's still resistance it's not the power button for me.

uhm, I actually did fix it... while it's not completly back to normal i can at least turn on and off the phone, just turning display on and off with power button still doesn't work
some dust had gathered on the board, apparently shorting a circuit. just grab a brush and some canned air and clean the board.
i cleaned the main board at the very top and the bottom one near the middle (PM me for a photo of the location)

Nice that it almost works now. Just thinking what an asshole Sammy is, they want more money for a maybe ~20€ repair than the device costs bought new.

the repair wouldn't have been 20€, they'd have replaced the whole mainboard for me, not just the power button. I have no idea whether just replacing the power button would help, just brought that up as that's the one item that could possibly be it and you can get for cheap.
my power button got worse again since my previous post btw. so something else must be wrong as well.

After my phone was on a rainy trip, I am suffering from the same issues as well. I checked the resistance of the power-switch, and the open-circuit resistance measured to 30 Ohms, while the closed resistance measured to 0. Of course, the open-circuit resistance will not measure the switch isolated, but still, I'd expect something in the range of at least some Kilos. Hopefully, the switch will function normally in some time (if the switch is the only problem).

if it doesn't fix itself remove the mainboard from the housing, check it using a strong magnifying glass for any traces of water (tiny white residue spots) and carefully clean them using with a small brush (and nothing but that!).
of course doing that will void all warranty!

I completely disassembled it in order to clean it properly, but it did not yield immediate results. However, however a few days of rest and it came back to life, and has been stable since. So it looks like the rest is the best advice for other unfortunates.

[Q]Bootloop and Battery not charging

Hi, so my phone decided to stop working all of a sudden.
I was just doing things on my pc when I heard my phone rebooting, after I had recenly plugged it in.
It's running the latest stock ROM and not rooted. When I try switch it on it shows the Samsung Logo and on some occations some pixels create a fuzzy area underneath the logo text and at the bottom of the screen, it then switches off and after a while tries to boot again. When I try charge the phone it goes to the battery icon with the loading circle but nothing moves and yet again some of the pixles of the battery icon become distorted and then it switches off and tries again(also it vibrates twice before showing the battery icon). I can boot into Dowload mode and my PC recognises the phone(as well as odin) but I can't boot into recovery, or Safe Mode for that matter. I can remove the battery when in dowload mode and the phone remains on but I need the battery inserted to start up anything. I've only had my phone for two months now. Maybe I could be moisture from my shower earlier, I'll leave my phone in a bowl of rice overnight to see if that does anything.
Please try help me fix my problem. I've been looking for a solution all night.
Also due to me being overseas I can't format my phone as I'll lose my WhatsApp validation and all the pictures I've taken so far will be lost.
Thanks in advance.

It's not a software problem so you don't need to format.
My guess would be that you need a new battery.

The battery isn't even swollen though?
I just tried starting up the phone by turning it on, then plugging in the cable and hitting the battery out but it still didn't boot.
Unfortunately I'm far away from a big city so I can't get another battery to test it to be absolutely sure though.

Update:
I just tried booting it again and it got to the other Samsung screen where the LED is Blue and the Logo flashes blue behind it(Only got here once, hasn't gotten this far again yet). I left it for a bit but it just got stuck there and there was the same distorted pixels like in any other type of screen I get to also the logo stopped flashing when I tapped the screen and pressed the home button(this is when the distorted pictures started again).

Here is an attached Image of the flickering part of the screen. It gets stuck on this screen and flickers at the bottom and just underneath the Logo and eventually turns off.

No one know the problem?

It's a hardware failure. Let's hope it's your battery even though it's not swollen.

I tried a new battery today and it had exactly the same problems

So by some miracle it booted all the way to the lock screen and then rebooted from there right back to the lock screen again and I unlocked it and the home screen was fine and the phone seemed to function for a few seconds then it restarted and then got stuck at the Samsung logo again, I did manage to see that there was 17% Battery left so It has enough power to boot it. So I dunno what the hell could be causing it. It's such a weird problem I have no idea of how to fix it(within the warranty that is). I forgot to mention that the screen has 3 stress fracture cracks on the screen so somehow I think it is bending in my pocket, so that might be a reason why it's acting so weirdly.

I also noticed that if I leave the battery out for a decent amount of time and try boot the phone up it boots up for about 20 seconds and then reboots again into a bootloop again. Also the battery percentage is at 0% apon boot, by this stage I've plugged it into my PC to try pull files off of it(Which I managed to get some files off).

Screen stopped working, burning out?

SO Sunday morning I wake up and my phone has been on charge all night, its 100%, I unplug the phone and about 10 minutes later its very hot and at around 60% battery. So to stop this I go to turn it off and start seeing these red "bubbles" under the screen like water but its the LEDs turning red. I have never dropped the phone or put it under water. Its a hot day as it is and about 5 hours later I turn the phone back on and its fine for around 15 minutes watching youtube videos, it then starts flashing black, like the whole screen shuts off for half a second and comes back, still sound playing, about 5 minutes later the phone starts glitching out and the pixels on the right hand side start turning red (no link) like so. Then the phone starts jumping between that and this ( no link ) which happened for around a minute and since then the phone screen is just black and doesnt display anything but the phone is still active and had feedback on the screen such as touch vibrations. Really want to know whats happened and why if anyone can help

Probably a hardware defect that will be covered under warranty. But possibly a software problem that's causing the cpu and gpu to run really hot. You can try booting into safe mode to see if that makes a difference:
Shut the phone off and let it cool down.
Boot into safe mode: https://www.google.com/search?q=gal...rome..69i57.3932j0j7&sourceid=chrome&ie=UTF-8
Use the phone for a while, and see if the problem reoccurs. (Your 3rd party apps will be disabled, so you won't be able to use them, but you can do other things.)
If this seems to solve the problem, delete any recently installed apps, or factory reset the phone, and see if the problem stays resolved. If so, add your apps back in a few at a time, so if the problem reoccurs you'll have an idea what caused it.
If none of this solves the issue, it's a hardware problem.

My wife had EXACT same problem. Backup everything while you can as my wife's phone died few hours later. (no display at ALL - digitizer was working fine though - so could shut down, etc). Symptom also was that when you reboot, it will display the boot up screen just fine, but as soon as all white screen was able to display, display will just die, etc. Pressing power button repeatedly would eventually turn on the screen but color would be off and simmering, etc.

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

galaxy s5 display issues

My galaxy s5 started acting up a month ago. The screen will flicker green/yellow then go black, or stay black entirely. It got a lot worse recently where it will only work hitting the power button 1% of the time. Is this a hardware issue? Or software?
When the screen dims before sleep, it spazzes out too. I've noticed it works better when it warms up from charging too. But still fails to display way too much. It still registers touch when black. I replace the battery a few months ago BTW.
If the device has no hope, can you guys reccomend a good cheap phone?

Put your phone on max brightness & set your phone to never turn the screen off
Leave your phone screen turned on with max brightness for a at least a few hours
If that doesn't solve it then you may need a new screen - it is a hardware fault on these devices with these types of screens

If I were you I'd also follow the advice of
TheFixItMan said:
. I'd make sure to run a slideshow in your gallery while having your screen at max brightness though as this may reduce the risk of having burn-in on your screen.
If all fails you could buy a new display for your S5. I did so myself recently as I kept having "snowstorms" on my display when I turned my phone/ the screen on. Worked for me, managed to get a new and genuine one from a reputable seller on eBay. Hope you won't have to resort to the latter though.

@TheFixItMan thanks for the advice, I tried it last night, and it didn't improve at all. Is there any possibility that the device isn't giving the screen enough power? Because I have better success when its plugged in. What do you think caused this to happen after 5 years?
@James160103 Thanks, I tried it and it didn't work. I'm exploring all my options. For $10 more then an OEM gs5 screen, I can get a gs7.

Perhaps it's got something to do with your new battery then, did you buy a genuine Samsung battery? How about sticking the old one back in and seeing if that makes a difference?
Also try using a genuine Samsung power adapter and charging cable.
It's worth a try anyway. Let me know if that made a change.
If it doesn't help you could remove the screen from the phone and press the flex cable from the digitizer downwards to see if it might be a loose connection between the motherboard and the screen that's causing the problem. I'd try that as a last resort though as you could damage your display in the process (replaced the screen myself and managed not to break anything, did it for the first time). There's lots of videos on YouTube (I recommend JerryRigEverything) that could help you out.
While this is unlikely, you may want to try before buying an S7.
Also, try booting into TWRP and playing around with the brightness settings and turning the display on and off again to see if it's some bug with the OS (again, unlikely but it's worth trying).
Please let me know if any of the oprions worked for you or made a difference, cheers.

@James160103 my old battery can't hold a charge, so I disposed of it. My new one has been fine for a few months without any problems. As far as a charger, I have a better charger then the stock, and a thick gauge nylon wrapped cord, that's been doing fine for the last 2-3 years.
The whole display issue isn't just on the OS, when I boot normal or into recovery it stays black, or flickers for a split second.
I did notice that if I hold it in front of my car vent, with full heat. Once its warm it seems to work, just until it cools off. I'm guessing its a hardware issue at this point, but I'll try to check the connection.
Thanks for your help

Facing this exact issue. It has gotten worse now.
