My phone keeps QUICKLY flashing the "Samsung Galaxy S8 powered by android" screen when it's on the charger. It's just black and completely unresponsive when it's off the charger. (I tested the charger with another phone, works 100% perfectly.) Here's a video of the phone flashing when it's on charge.
None of the buttons seem to have any effect on it whatsoever. This is my old phone but there is vital data on it that I need to get, so a factory reset is completely out of the question.
Is the battery good?
Booting uses a lot of current, a charger likely can't provide it.

I don't know, it was working fine the last time I used it, all I did was neglect to charge it.
Is there a way for me to make it stop TRYING to boot so the battery can actually charge?
When was the last time and how much charge did it have?
They lose about 1.5-2% of their charge per month. After the phone auto shutdown because of low battery you usually have a month or so before the internal battery controller permanently disconnects the cell making it unusable.

Can it try to boot without the charger using the power button?
Does it show a charge level in it's off state normally? If so is it doing that?

it's been a month or so, what can I do now? I HAVE to recover that data

What happens if you try to go into the boot menu?
If you can't get it to boot the data is likely lost.
Always redundantly and regularly backup critical data.

I'm assuming you hold volup bixby and power. If so, it's not doing anything on and off the charger cord.
I'm going to need you to explain how "the data is likely lost" though, I doubt the battery erased the data on the phone, right? This data is absolutely essential and I wasn't aware of this before letting the phone drain, so it wasn't backed up.
If it's suspected failed battery, replace it.
The data is still likely on the flash memory but if you can't boot it, the data is inaccessible for all practical purposes.
It's also possible the C port pcb failed, both the battery and this part are relatively cheap.
Probably best to let a repair shop look it over.
A Samsung Experience center at best buy be another option.

Background: I had my completely stock Nexus 5 on the charger for around an hour. When it got near 100%, it locked up for about 5 seconds and powered off. It wouldn't charge or power on again until 2 days later where it would power up but not charge. It could go to the bootloader/recovery but it would still shut down. The charger used won't charge anything anymore, it may have been a power surge that messed it up.
I replaced the battery and the system is still unable to maintain power but recovery and the bootloader are stable (just formatted the cache and the phone did not power off, took around 15 minutes). Now it won't power up again.
Any idea what the issue could be? Could it be corrupted data?
First, try another cable and charger.
Also, make sure you have enough juice on the device first, reflash stock firmware with fastboot and see if the issue remains.
If you successfully flash your stock firmware and use another known working cable and charger and it's the same.... Then unfortunately it could be a hardware issue.
Thanks for the reply.
Unfortunately, that didn't bring my N5 back to life. I'm think a circuit may be fried on the motherboard but I don't have a real way of judging that at the moment.
Any chance you might be able to guess what the hardware issue could be? I'm mainly trying to save the data on my phone and I'm not against taking the phone apart to do that.
Update: I took the phone to a Sprint store and a technician looked at it. When the tech plugged it into the charger, the phone LED was flashing red with no charging screen. It eventually booted up and shut down. Later that day, I could see my notifications (Pushbullet is a wonderful app) and noticed the phone stayed on consistently. He said everything was fine and their formal report didn't mention any sort of damage to the phone that they could find. Later that same day, it died again. Today, I decided to completely wipe and load 5.1 to the phone. It stayed powered on through the whole flashing process (bootloader unlock and individual partition flashes) but shut off during "optimizing apps". Considering it powered off in the system, I'm thinking the issue is with the RAM or the CPU possibly being fried due to a power spike while on the charger. It seems like it only happens during heavy operations.
Something hardware it seems. Not sure what, but if a component on the mb is bad then it is a replacement.
I like the title though, doubt anyone has a device that stays charged while in system. Sorry about your phone, but made me chuckle. I really can't think of a better way to describe it, not trying to pick on you.
Hello,
I had an accident and after that my Nexus 5 screen was broken. So I decided to buy an new one from Amazon (~60$) and I tried to replace the screen on my own.
Yesterday I replaced the screen with a YT-Video, then I charged my Nexus 5 an the "Charging-Symbol" showed up.
After that I left the house for 2 hours and when I came back (I left the Nexus at home for charging ofc.) I tried to turn on the phone and nothing happened.
Then I tried to press power and volume down to get into the boot-menu and this also worked and the screen showed everything perfectly (!) and then I tried to start my handy from the boot-menu.
Until then everything has worked well but during the start progress I noticed that the (starting-)animation is really slow and laggy, so I decided to try to reboot my phone by holding power off for around 10 secs.
I tried to start my phone one or two times more and tried to get into the boot-menu, restart bootloader, etc. and then I realized that my phone didn't even want to work anymore. I could(and can) neither get into the bootmenu nor simply start it...
Do you have any ideas?
What suprised me the most is that it stopped working so quickly, so I concluded that I replaced the screen right but anything else went wrong...
Please help me :/
PS:
USB-Debugging is turned off and I cant access my phone with my pc or anythin else
Leave the phone on the charger for about an hour and then try to get into the bootloader.
When my phone is in the process of booting and I force it to power off by holding down the power button, it will not power up until I either leave it on a charger for a bit or leave it power off for a bit, usually 5 to 20 minutes.

Thanks, now I could get into my phone and enable USB-Debugging with much lock D)
My problem is, that my phone runs very unstable and shuts down often so I can't really work with it.
Do you know any solution and the more important question:
How can I save my data? I think, that I can save it anyhow if I enabled USB-Debugging with the bootloader and a pc, can't I?
Yes, you could pull the data from the phone using ADB commands.
You could also flash twrp to the phone. Once flashed, you could boot into twrp, mount the data partition, and copy data from the phone to the computer.
You could also use twrp to create a nandroid backup for safekeeping.
Is it possible that there is a loose connection in the phone? Have you tried disassembling and re-assembling?

I have now moved on!
My charger cabel was broken but now I got a new one!
I can start my Nexus (with some issues) and it runs but sometims it still shuts down and always when I try to plug in my cabel into the Nexus the screen gets black (but on the side you can see that the screen is light up in some way, idk...)
Is there a reason for the heating and for the shut downs? :/
I'm not sure but it seems like the screen has suffered a hardware malfunction because you can see that the backlight is on but no image.

And that means what?
And can I do anything for it? Maybe flash it or something?
Reset, etc..
With a hardware failure, there's nothing that software can fix. Did you try disassembling and re-assembling the phone?
With the old screen, can you see anything on screen? Did the phone power up and charge properly? If yes, put on the old screen to test the other components to see if it charges and powers up.

Yeah first sentence makes sence..
I swapped software and hardware, sry
my other screen doesn't work at all, completly destroyed...
The problem is that I can't imagine what should be the failure...
And yeah, I already tried disassembling and re-assembling it...
Still same problem
I have used cheap 3rd party screens to replace a few N5 phones and they quality is very inconsistent so I wouldn't be surprised if a 3rd party screen fails after a short period of use.

Nahh but the screen works I think..
Everything looks clear etc and the screen wasn't really cheap with 65$-70$ I guess..
I think it's something else because my phone gets really on near the CPU and this can't be because of the screen...
Where did you get the screen?
If it gets really hot near the cpu, then something else is going on. Could it be possible that there is a short-circuit somewhere?
Since the value Canadian dollar has dropped, I'm also paying about $60 for what was a $40 screen.

Yeah, I also thought about a short-circuit but I don't know how I can test this.
When I try to start my phone it fails like 4-5 times and then it works most of the time. The fail looks the following:
The "Google" logo appears and then suddenly the screen gets black, but not the "out"-Black (so that screen it out), I mean the "on, but black"-Black (hope u can understand.. xD)
During this 4-5 Tries my phone feels like 40°C-50°C (sry im from Germany, idk the conversion to °F value.. )
After this (I got the phone running one time for about 20 minutes) the phone doesn't heat up so much, if it starts right I think that the temparatur problem is over, but there is still the problem (also if the phone is running for 20 minutes) that it suddenly shuts down... :/
Sorry, idk much about canadian dollar, like I said im from germany and I payed around 65€
Google says, that this is around 67 (US-Dollar)
I don't know what to suggest other than either getting a new battery or new screen. Both items can be very expensive.

Mhh, ok :/
Since two days now, my Nexus 5 turns off on turning on data or Wi-Fi or even taking a photo. I can't turn it back on unless I connect the phone to the charger. There is no drop in battery charge either on turning it back on. To use data and Wi-Fi, I always have to use the phone in charging mode. I even tried clearing cache and factory reset from the recovery mode, still no luck. Please help.
How long does the battery last if not using data or wifi at all? Sounds like the phone may need a new battery.

Well, the battery would last an entire day. I got the battery replaced a while ago and it is all good now.
I have a moto g6 I used a while ago. I upgraded my phone when it stopped charging. I thought it was the USB-C port, and moved on to a new phone.
I just took the old phone out again and booted into recovery mode this morning. I plugged it in and it charged (in recovery mode). It trickle (slow) charged for most of the day. I then booted the phone up about 2 hours ago and it was mostly charged.
I tried plugging the charger back in, and again..... no charging.
I booted back into recovery mode and alas. Charges. Albeit slowly.
It only charges when it's booted in recovery mode. Any thoughts?
<bump>
⌐(ಠ۾ಠ)¬
Does it charge when powered off?
Nope. When it's powered off, it will start powering up as soon as I plug it in. If the battery is full, it just boots up the phone when I plug it in. If the battery is dead, it will show the boot logo, battery 0%, and restart. On loop.
It only charges/detects there is a charger plugged in when booted into recovery mode.

You mean when it's been completely powered off ie shutdown it boots up by itself up when you plug in the charger?
Completely power off the phone and try the charger.
Sorry, just tested again and I'm wrong, slightly.
When I plug it in while turned off, it will show the lightning icon, then a battery percentage, then restart. It never boots up by itself when plugging it in.

Are you commanding it to restart ie hitting the power button?
If not it's either a firmware failure or more likely a hardware failure.
Self-restarts. Without any action on my part. It just shows the current battery % and then boot loops.
I had the USB port tested at one of those 'fix your phone' places (when the problem first occurred) and they said the USB port is fine and it's something else causing the problem.
I just find it super strange that in recovery mode, it will actually charge. I had given up on this device and I'm using a new phone now, but the fact that it charges in recovery makes me want to get this thing back up as a spare.
I spent a LOT of time on google for this and I have not found any useful information or ideas.

Try a factory reset if stock.
Reflash firmware to known stable version.
Hopefully that will fix it but don't count on it.
If that doesn't get it than it's a mobo failure or less likely an issue with a connector.
Depending how it's laid out it could be a failure in a subassembly rather than mobo.
Sorry...
Epic necro, but wanted to reply to say I have the exact same issue with a Oneplus 5T right now. But I think I can add one note: I installed AccuBattery and that shows that the phone *does* charge when connected under Android (even though the charging icon doesn't show), but very slowly; it's charging at 500mA, which I believe is the base USB spec max for power transfer.
In typical use it's entirely possible you consume more power than that, so the battery percentage would still drop and the phone wouldn't appear to be charging. I suspect it's actually doing the same in recovery mode, but recovery mode uses much less power - so 500mA is actually enough to trickle-charge it - and does show the + sign to indicate charging.
I haven't found any fix yet either I do suspect blackhawk is right and it must be a hardware issue. I'm gonna take it to some repair places and see if I can avoid a big replacement bill.
Is the battery good? Or is SOT short?
Could be a failed battery.
Any swelling is a failure.
Erratic fast charging is a symptom of a battery failure.
Li's can fail at any time in their life cycle.
Typically in a heavily used device they last 1-2 years. When they reach 80% of their original capacity they have reach the end of their service life, are degraded and should be replaced. A degraded Li is more likely to fail.
An easy fix if so.
Nope, already replaced the battery not long ago. It was indeed the port: took it in for repair and the guy said the trace connecting the port to the motherboard was basically gone, probably wear/damage over time (this phone is five years old and has been dropped a few times). He fixed that and it's back to charging like a champ and connecting to PCs fine again. So, if OP is still trying to fix their G6, might want to try a different repair shop...
Actually its a software bug. Factory reset ur device from recovery mode may problem will be solve.
Hi, My s21+ was fine last night, but when i removed it from my wireless charger this morning the screen is completely black and un-responsive. The ringtone was sounding when someone called me earlier but following troubleshooting from samsung its no longer responsive at all - its no as if the phone isnt even turning on anymore.
I am eager to get the data from the handset, and am willing to take whatever steps neccessary to recover as much a I can. I have tried samsung smart switch PC but the phone is not recognised. I also looked (briefly) into wondershare mobiletrans, but that requires me to activate USB Debugging, which is impossible with a non responsive handset.
What are the best steps for me to take? I am not bothered if the handset works or not, i just want my SMS and Gallery saving if at all possible? There are some SMS's on there from my mum before she passed away that are quite sentimental to me.
All advice gratefully received.
Thanks in advance.
If you can't access the boot menu, there's nothing you can do without repairing the hardware failure first*. If it's the mobo only a data recovery specialist will be able to retrieve it.
If it's a battery failure, replacing the battery should put you in the pink again. Li's can fail completely with no warning but usually it's the degraded ones that fail ie less than 80% of original capacity. Any battery swelling is a failure.
This exactly one the reasons I always use a SD card as a data drive and back that up redundantly. With no data drive regular backup of critical data is mandatory. Phones with no expandable storage put you at a disadvantage in more ways than one. Regardless without redundant backup data lose becomes a question of not if it will happen only when it will happen.
*Try this to fix the black screen of death.
The phone is basically faulty right out of the factory: your screen has a bit that's either torn or disconnected from where it should be. I'd wager if you charged your phone suddenly it went dark its the black screen of death. In my case the screen was off but touch still worked. Left the phone alone for half a year, picked it up and suddenly it worked again. Brainless Samsung.
You should be able to recover your data probably easily. What happens when you connect the phone via USB to the PC? Or when you just charge it? Can you try charging it for a while, booting it up and then if you remember to, unlock it blindly (treat the screen as if it wasn't off)
