So I have a pretty interesting problem and I'm hoping somebody here could give some advice if they've ever had this problem or knows how to fix it. So here's what happened, I have a galaxy S8 and I tried plugging it into my computer to charge it, and it prompted the question something along the lines of, "this computer wants to access data on your phone" and it gave me the option allow or deny. Pretty standard stuff. So I pressed allow, and the same question was prompted again. So I thought huh that's weird, and I kept pressing allow over and over and nothing was happening it just kept coming up again. Pretty annoying. Anyways, I gave up on that after a while and went to plug it into the wall charger like I normally do, and I was surprised to see that it wasn't charging anymore even when I plug it into the wall. I tried switching ports, I tried switching cables, and nothing worked it just quit charging. And I'm just wondering what could have caused this problem? The only thing I can think of is that my computer short circuited the charging port or something, but when I plugged it into the computer again after that it still did the same thing with it asking me that question over and over again, so it obviously recognized that a device is being plugged in which means the charger port should be working fine. Another thing, when all this happened my phone was at 10% battery life, and I tried to turn my phone off and plug it into the wall that way to troubleshoot and see if that would make it want to charge. It didn't charge, and I tried turning it on again but now it is at 0% all the sudden, so I don't know why that happened either. And here's the kicker, this same thing actually happened to TWO of my devices. It's just the first time I didn't realize that it was my computer that messed it up, I just thought that my phone was defective, but it was covered by my insurance and they sent me another one for free(which is awesome). It wasn't until today when it happened again and it clicked that it might not be a defective phone but somehow my computer messed it up. Anyways, I know this was long winded but I wanted to be detailed so you have all the information. If anybody knows how to fix this your advice would be really appreciated. Thanks.

to be sure it is not a software problem, open the "USBSettings" by dialing "*#0808#". Try different settings (it shouldn't matter which one you choose, it's just about the resetting of whatever is in there. then connect it to your charger. If it doesn't work, I would reboot the device and try again...

good luck!

Thanks for the response. So I did try that and nothing changed so I guess it's not a software problem. And I actually have an update to the story. I bought a wireless charger and I figured that would work for sure, and my phone turns on but it just stays at 0% and doesn't charge at all. So I really don't know why it would do that and that makes me think that it's something wrong with the battery? I really dont know haha

Are you using usb 3.0+ on your computer?

I have USB 3.0 on my computer but I believe when it happened I plugged it into a USB 2.0. I've had issues with my USB ports acting weird on my computer before. Maybe it has something to do with that?

It's very possible as I have seen a high number of issues with USB 3.0+ and they s8 series. Always try to use 2.0 with this phone. Ive had 2 s8+ have their charging port trying to tether threw 3.0. Had to send them both in. I haven't fount the exact conflict yet but am working on it.

if you recently put it in water, it wont charge until its dry. I doubt this is the problem but its a suggestion. can you boot it up when its plugged in by holding Vol Up, Power, and Bixby? If not try the same thing with volume down. Some old phones booted up like this when there was no other way.

Good luck, this sounds like it sucks ;(
