I have a dead Samsung S8, can I fix it? - Samsung Galaxy S8 Questions and Answers

This post is probably hardware related, so I hope it's not that irrelevant here.
I have a Samsung Galaxy S8, SM-G950FD that hasn't been used for over a year because it's gone completely dead. Won't turn on, not even battery charging display, i tried charging it overnight and still no results, the battery doesn't even get warm. I've tried bringing it to a service center but they don't fix Samsung phones, so I decided to try fixing it by myself.
The first thing I do is I check the battery, it does look weird but I'm not sure if it's the main problem. Here's the image of the battery.
My question is, could the battery be the reason the phone won't turn on? or could it be other things such as my charging port, or the display screen itself?
Again, sorry if I made a mistake somewhere, thanks for any help.

Replace the battery. Go from there.
It won't boot without a good battery.

Thank you! I'll definitely do that, but I got a question, can a phone be turned on by using it with a charger without having a battery attached?

The charger might provide enough current to open the boot menu. Booting uses a lot more current.

hm I very much doubt it, pretty sure you need a battery.

Not sure. There may be fail safes. They're designed to operate from the battery.

update,
I changed the battery with a new one, it still doesn't turn on, nothing shows on screen.
I guess it has something to do with the motherboard then.

If they are good they have to unless they reached their auto shutdown voltage. Typically they have a 50-70% charge.
Hell you can get a used N10+ for $300 and up. It's a quantum leap in performance.

Do you have any indication it is booting? Like do you feel it getting warmer? If you do it could be a bad screen. I have an S8 with a bad screen and it's just blank but I can tell it's booting because of it getting warmer and vibrating. I think the S8s are known for having the screens fail. I can get a replacement screen on Aliexpress.com for less than $100 but it would only be worth it to me if I could put on a custom ROM. Unfortunately, bootloaders on snapdragon S8s can't be unlocked and probably never will be. So it's not worth it and I guess it's going to the recycler.
The irony is that my old Exynos S7 is happily running a custom Android 12 ROM and doing everything I need it to do. So if you are in the market for a super cheap unlockable Android phone you can't go wrong with an Exynos S7 running Custom Android 12 ROM.
I just bought an Exynos S10 off ebay which will be replacing my S7. Qualcomm/Samsung can go pound sand trying to force us into upgrading our phones every few years.

Where you running Faux's kernel?
Can you hold down the Vol +/- and then plug in your USB cable? If it is a red blinking light then I think it's a battery issue not supplying power to your motherboard.

This happened to me today. The battery indicator is incorrect, and shuts down before notifying you sometimes.
Phone shut down on me randomly and wouldn't turn back on today. Plugging into the wall didn't help. It was only when I plugged it into my PC and let it charge for 5 minutes that it came back. Scary bug.

No need to type in bold...
Faux is a developer who is putting together a new kernel for our device, basically it allows one to modify the 'engine' of our phone.
I think the consensus here is there is a manufacturing defect in your phone and a lot of other phones. It seems like this issue is connected to running a custom kernel but there are reports of 100% stock phone bricking (like yours)
It's time to call up google, nothing we can do from here.

I thanked you on accident, you didn't deserve it. There is no evidence that his phone is bricked, a user above reported the same thing happening and how he resolved it.
Also, he can type in bold if he wants to.
I hope the OP issue gets resolved. Wish you all the best buddy!
I'm having the same issue. Except this happened when I pulled the device new out of the box. Can't even get it to stay on long enough to get into bootloader mode. :-/ RMA time
Good luck on fixing the problem.

[Q] Battery problems (phone won't turn on or charge)

So about a week or two ago my phone randomly shut itself off. I'm not sure exactly what happened but I just locked it and slid it in my pocket and an hour or so later I checked it and it wouldn't turn on, yet I could feel the gpu/processor getting extremely hot after a minute or so of failed attempts. Also the trackpad would flash red, which I had never noticed before. Prior to this I had been noticing my battery was draining quicker.
So when I try to charge it will charge itself for approximately a minute or so and then the orange LED will go out, again the processor/gpu gets very hot. After about an hour if I come back the phone will feel cold again as if It had been off and the phone won't turn on. I was able to buy a new battery today, because I read it could be related to a dead battery. This new battery boots to the familiar HTC mytouch4g intro (which is good, considering the old battery doesn't even power on), but then will shut off immediately after that or occasionally just get stuck at that screen. I can boot into recovery but then it says low battery voltage. I tried to do a factory reset but it just takes me back to the bootscreen again and shuts off.
I'm not sure what to do, as I've bricked a previous phone before and this doesn't really seem similar. I'm thinking about leaving the phone on charge, even though the orange LED is off with the hopes that it will charge. Anyone else have similar experience to this?
You tried different chargers?

Yes, by holding down on the volume and the power button right? Almost every option leads back to the phone rebooting.

Sorry about the long response time. Unfortunately now my phone will not turn on with either battery, so I couldn't flash the img. I think it could be possible that my phone is not actually charging the battery and both of them have died. I'm not entirely sure, I'm going to charge it overnight and hope for the best.

[Q] Screen Turns On Randomly Without Touching Phone

When I leave the Nexus 4 on a flat surface with nothing around it, it will randomly turn the screen on, wait the 30 second timer, then turn back off.
I did just install 4.2.2, but I hadn't used it enough before to say if it only started since then.
I'm currently unrooted, though unlocked the bootloader when I first got it so I do plan to root soon, would flashing a custom kernel like franco kernel possibly fix this? Or would this be a problem in the rom or a third party app?
In BetterBatteryStats I saw 2 Kernel Wakelocks that seemed to have a high ammount of wakes.
(Screenshots Attached)
And here's the BetterBatteryStats Dump File: https://www.dropbox.com/s/dbc2vn3littc0fp/BetterBatteryStats-2013-02-21_054751350.txt
Any help would be highly appreciated, thanks.
Possibly a third party app.

Err I meant like, it keeps turning the screen on and off - like if the charger is disconnecting itself.

It does that with all sorts of different cables and chargers. Think I might have a loose USB port?
Maybe it's linked to the Daydream feature?

Not sure, guess it's possible, but even if it is lose I wouldn't expect it to effect it once it starts unless it gets bumped.
Also, what is the temp of the battery when charging? Not sure if it's true but I've heard that if the battery is over 40c it won't charge properly.
If you want, here's a really nice widget with temp on it: https://play.google.com/store/apps/details?id=ccc71.bmw
I would just be careful with anything to void your warranty until you figure out whats causing the problem, as I've heard a lot of stories about bad batteries, and shorts in usb causing the red light bug (For lack of a better name).

Thanks for the link. I actually looked through the 'must have apps for the N4' thread under themes and apps, and Goku80 had posted a link to a battery meter that I just downloaded and installed moments ago. I have yet to see what the charge temp is, but I will report back tonight. Idle temp is around 25*c from what I've noticed just now.
The only thing I've noticed with temps so far is when I have my phone pulled in and I'm watching something on the phone. The phone gets really hot, and the system starts to lag badly. I would assume this is a fail-safe for the battery to not overheat by downclocking itself, but this is only a theory.
As for the red light bug, I saw my phone drop from 28% to 4% instantly out of nowhere yesterday, with no warnings. I immediately pulled the phone in, and watched the battery meter jump to 30%. According to the red light threads, I think it's a software issue with the phone shutting down completely when it thinks it's out of battery to prevent damage. Hopefully we'll never run into that issue ourselves.

Galaxy Note 4- Why Is My Phone Working Without The Battery?

Phone actually working without battery???
Okay this is weird... I am new to this Android developing stuff so cut me some slack...
I just took out the battery to restart quickly, but it stayed on... I made sure the battery was far enough away from the device to not be using any sort of black magic. I left it for a while and eventually I just put it back in and rebooted through the menu. What was happening? Draining from the RAM to keep the display on? Some sort of solar panel? I am confused!
Remember to unplug the phone from charger cable...
I would vote for black magic but it's probably just a anomaly . My 910F as soon as i unplug the battery will go bye bye in 0.5 sec ! )

After you remove the battery, there is a little sticker on the phone where the battery slot is (it has the phone model number on it, as well as other information). Sometimes you need to flick the sticker with your finger a few times. This tells the Pikachus in the phone that the battery is out and they'll soon stop using Thunder Bolt.

Yes it's draws current from any power source connected to the phone. Some phones will shut off when battery is disconnected even tho a power cable is connected to protect hardware from shorting out and other phones won't.

How can i prevent my phone from shutting down before the battery % reaches 0?

My note 4 shuts down before the battery percentage reaches 0. How can i fix this? Im using a debloated stock rom (https://forum.xda-developers.com/no...rom-n910tuvu1anj7-4-4-4-deodexed-ciq-t2915737). Ive tried this: https://forum.xda-developers.com/note-4/general/battery-shutdowns-15-20-fix-root-t3513268, but it didnt work for me.
Edit: im using a new original battery.

I'd suggest NOT getting an original battery, since there's so many counterfeits out there, unless you're directly buying from Samsung. Get a reliable 3rd party battery on Amazon with at least 18month+ warranty. It's very likely the 'new' battery you have is a counterfeit, or refurbished. I gaurantee it will be fixed with a GOOD battery. Get a refund if it still behaves that way. Cheers :highfive:
I have bought 5 battery's on ebay before I have found the right one
