S8 Plus won’t turn on

Galaxy S8 wireless charging stopped working after an update

Hello Android fans! Here’s another troubleshooting article for the Galaxy S8 (#GalaxyS8) for you. We bring you 4 more cases of the Galaxy S8 not working as expected. Keep in mind that not all Android problems can be fixed on an end user’s level. So, if nothing works after you’ve exhausted all software solutions, the problem must be beyond your ability to fix.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: Galaxy S8 Plus won’t turn on after an update

Greetings. My Galaxy S8 PLus has all the symptoms described in this article: https://thedroidguy.com/2018/10/samsung-galaxy-s8-went-completely-dead-turned-off-wont-charge-anymore-easy-steps-1079742. I had it beside me on my bed, unplugged, when I realized it had turned off by itself. The power button didn’t bring it back up and none of my chargers make it charge either, haven’t used a wireless charger.

i did notice it was able to get hot on it’s own without being plugged after it had died. I’m certain it doesn’t have any physical damage, it has a RhinoShield bumper case, it has no bents, scratches, cracks or anything. It hadn’t had contact with any water whatsoever for at least 2 days and I had already charged it plenty of times, there was no moisture inside the usb port when i inspected it.

I was wondering as well, if you knew anything regarding it’s guarantee with Samsung. I bought it brand new in February, but it came from Saudi Arabia and I don’t know if Samsung will honor it’s guarantee here in MEX.

Also a thing to point out. This happened right after I updated the new software update, it couldn’t have been more than 1 or 2 hrs and I’m not sure if it even came back up after I updated it.

Solution: When it comes to an issue such as this, there’s very little that you can do in terms of troubleshooting. If you’ve already tried to all of the following

  • force reboot
  • charge using another set of charging cable and/or adapter
  • left the phone charged for at least 30 minutes

and did not get any positive result, then the only other troubleshooting step you want to try is to charge the phone wirelessly. If that won’t work still, you can assume that the system is dead. If the problem occured right after an update, it’s possible that there’s a firmware issue behind it. In most cases, the real cause lies on the hardware. Either way, you’ll need to let a professional check the device and there’s no better to do that than a Samsung technician.

As far as warranty is concerned, any brand new Galaxy device has a one year coverage. The terms though varies from region to region. If your S8 Plus was originally sold in Saudi Arabia, Samsung Mexico will most likely decline any support for it. That’s because their Service Center may not be equipped to handle hardware or software issues from non-Mexico devices. Warranty terms and conditions in Mexico may also be slightly different from that of non-Mexico countries. To be sure, we suggest that you contact your local Samsung Service Center.

Problem #2: How to fix Galaxy S8 sound issue: media volume becomes erratic when using Pandora app

I am having the same issue as the Galaxy S8 user whose solution you posted (Google assistant keeps opening and messing with the media volume, although it happens when I listen to pandora). I tried to follow your solution, but when I tried to turn it off, the only options available were “turn on” or “no thanks”, the latter of which would take me through a whole bunch of options basically trying to get me to choose another one of their services. So, I have put my phone on safe mode and observed my phone, while watching youtube and other types of media, in order to replicate the issue … nothing further has happened. What would you suggest from here? Thank you! 

Solution: If your S8’s media volume works fine on safe mode but becomes problematic again once you boot it back to normal mode, one of the third party apps must be to blame. It’s likely that it may be due to your Pandora app. To narrow down the possible causes, you can use the method of elimination to pinpoint the problematic app. Here’s what you need to do exactly:

  1. Boot to safe mode.
  2. Check for the problem. If the problem won’t occur on safe mode, proceed to the steps below.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. At this point, uninstall an app that you think is the source of the problem.
  5. After you uninstall the app, restart the phone to normal mode and check for the problem.
  6. If your S8 is still problematic, repeat steps 1-4.

Problem #3: How to fix Galaxy S8 calling issue: phone appears to dial but can’t make a call

Morning!  I have one user that when he dials the phone will just sit there dialing but never actually dial. This happens daily.  I have tried restarting the device as well as clearing the cache. This is not working. The user states that this only happens when walking in the Shop.  I have an S8 Plus as well as others in the building and I have not heard this issue reported from others. I could really use your help. Thanks!

Solution: Most probably just a poor signal issue. Tell the person with the problem to make sure that the phone has excellent network signal (4 or 5 signal bars) during calls to avoid experiencing the problem. Some phones may have weak radios compared to others so if there’s poor network signal in your shop, his or her phone may not be able to establish good cellular connection.

Problem #4: Galaxy S8 wireless charging stopped working after an update

My Samsung S8 worked fine before the latest update. I already had Oreo, but this was another update after. The problem is the fast charging. I have done a factory reset and that didn’t fix it. It is not the charger itself. It is due to the latest update. There were no problems until then. And, I made sure the fast charging was on in the settings. How do I fix it? Thanks. 

Solution: Any update issue that can’t be fixed with factory reset requires seeking help from Samsung. The phone will either be repaired or replaced. If you are positive that your problem started right after an update and no software troubleshooting has helped so far, you can either send the phone in or downgrade Android.

The latter requires flashing of the previous Android version. Flashing has its risks but if you want to do it, try to find good flashing guides online to help you. Just remember, you can potentially brick the phone if flashing procedure goes wrong. Do it at your own risk.

How to fix a Galaxy S8 Plus with shattered screen and power issue

Hello and welcome to our latest troubleshooting episode for the day. We receive a lot of requests for help for the #GalaxyS8 everyday and below are some of them. This article will focus on giving you directions if you encounter problems with your S8 not turning on properly, or what to do when the screen is cracked and not working properly. In majority of these cases, the straight answer is to send the device to Samsung but there may be some exceptions.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: How to fix a Galaxy S8 Plus with shattered screen and power issue

Essentially I dropped my phone (without its case) on the sidewalk. My phone is a Samsung Galaxy S8 Plus, so it has that sleek screen. The left side of it was cracked. Mostly the upper left. It seems that from these cracks, a green line has spread horizontally across the screen. The line has changed in size and color multiple times. There also seems to be some kind of issue with turning on the phone now. The last time i turned the phone off, it took 10 minutes of pressing, and holding the power button as well as using the thumbprint system. However, all i could get was an extremely dark normal screen. (It was on,but there was almost no color.) I eventually got it to turn on normally, but now there is a keyboard thing that caused a word to type multiple times over. I’m sending this from my phone. Does this mean that the dreaded is true? Must I buy a new phone, or can it be fixed?

Solution: While some lucky few may walk without issues after accidentally dropping their phones, yours is definitely broken. The shock that resulted after that accidental drop must have damaged not only the screen assembly but also some parts of the motherboard, which is now causing the power problem. If you don’t want to invest in a new phone at this time, then you should at least let a professional take a look so a thorough examination is done. You can then get his or her opinion whether or not it’s wise to repair it. Keep in mind that replacing the screen assembly alone will already cost you about $200. If the motherboard is damaged, that should add probably another $200 or more, making the repair impractical. And just like any other electronic repair, there’s no guarantee that the phone will work normally afterwards. If you want to take that chance until you can replace the device with a new one, it’s your call.

Problem #2: What to do if Galaxy S8 won’t charge or turn on

Hi! This is actually my sister’s phone. She completely forgot about it when she bought a new phone and we just saw it. We tried to charge it, the LED light doesnt turn on. Tried switching cables and adapters and outlets but it still wont charge. Also, the reboots wont work. We also don’t know what is the verion of OS in the phone right now. Hope you can help. Thanks in advance ?

Solution: There’s only so much that you can do about this issue. If a Galaxy device won’t power on, it must be due to one of the following:

  • charging accessories (cable or adapter) are not working
  • battery is defective
  • charging port is not working
  • software bug prevents phone from booting up
  • there’s unknown hardware malfunction

Since you’ve already tried the troubleshooting steps a user can do in this case, that leaves you with hardware malfunction. This must be the reason why your sister left the phone unused until now. We suggest that you bring the phone to your local Samsung store or an independent service center so they can check what’s wrong with it. There’s no software trick that you can do to power on a dead phone so stop wasting your time and let a professional handle the case.

Problem #3: Why Call screen and Contacts app on Galaxy S8 revert to portrait mode when used

Why is it my call screen and my contacts screen will not work in landscape mode? it stays in portrait mode. Everything else works in portrait mode that should including the contact and call settings screen. they both work in landscape so why doesn’t the call in the contacts screen switch over to landscape. I have the auto-rotate turned on but it just won’t rotate on to those two screens which are what I use the most when driving any ideas?it’s a brand new Galaxy S8 Plus.

Solution: This is NOT a bug. Some apps revert to their default portrait mode when used. This is by design so the only explanation that we can give you is that Samsung engineers must have done this on purpose. Contacts and Phone calling screen returns to portrait mode whenever you use them. This is true for both apps in other Samsung Galaxy devices as well. If you want to let Samsung know that you find this default behavior annoying, try to contact them and give them your feedback.

Problem #4: How to fix a Galaxy S8 screen that keeps flashing and won’t detect touches

For the past week phone is not always responding to screen touches. Tonight, after I made a phone call, the screen went nuts and was flashing other screens that I’ve never seen before.  It would not respond to screen touches and I couldn’t shut it off. It just kept flashing different screens. Eventually it stopped long enough to get is shut off. Power was down to 16% and it is now recharging.  Is my phone clinically dead? My phone is a Samsung Galaxy S8.

Solution: The phone’s motherboard is possibly fine but its screen assembly may be defective. We don’t have the full history of your device so we can’t tell what really is going on. The specific symptoms you mention may be product of a general hardware failure or a sign of individual parts failing. For instance, your phone not registering screen touches may be an indication that the digitizer is damaged, while the flashing screen may be a sign of a bad LCD or monitor. Or, both can be indications of failing motherboard. These problems are usually not caused by software-related issues but it won’t hurt if you try to restore all software information back to their defaults. To do that, follow the steps below:

  1. Create a backup of your data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

If you are unable to factory reset your device, or if nothing positive comes out of it, then you want to go ahead with repair. We suggest that you bring the phone to your local Samsung Service Center first, or you can call them and set up an appointment.

Galaxy S8 showing Power Sharing notification when charging, won’t charge or turn on

Today’s troubleshooting article tries to address power and charging issues on the #GalaxyS8. We also include four reported cases of these problems so hopefully you can use them as reference when dealing with your own issues.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start.

Problem #1: Galaxy S8 Plus won’t turn on after accidental drop

Hi. I have bought my S8 plus in March and had no problem whatsoever and i took good care of my phone like always. Then one day (today) i turned it on because usually before i go to bed i always power it down. So when i turned it on it worked and everything was normal. Then an hour or two later it suddenly wouldn’t turn on and i put it on charge even though it was almost full and still no sign of a red/green light when charging. it was working fine and now i can’t see a single sign of life. i tried every single form of reset. I’ve checked for water damage although i’ve never placed water near it. I did realise one thing though. when i shake the phone i hear a rattling noise and the day before i dropped it but it was still working and not a single scratch or crack was there. I also had alot of apps but im not sure that’s the problem and im still under warranty but its doing my head in because i do not even know what has caused this and if i was being careless or this was a Samsung defect and not actually my fault. 

Solution: Like water damage, dropping an electronic device can have three possible outcomes:

  • it stops working right away,
  • it stops working or becomes problematic at a later time
  • or it works normally

If the only different thing that happened was the accidental drop, you should assume that your S8 Plus has sustained damage from that drop. A good working S8 or S8 Plus should not have any loose piece inside so we can only assume that it must be due to a broken component.

If the issue lies on the screen only, the phone should show signs of life like vibration or LED light when charging. If that’s not happening at this time, the phone is most probably dead. This must be the reason why you are unable to restart it to any boot mode.

Have the phone checked by a professional to see the true condition of its hardware. We strongly suggest that you let Samsung Service Center check your phone for this task.

Problem #2: Galaxy S8 showing Power Sharing notification when charging, won’t charge

I have a Samsung S8. Up until yesterday it charged fine, although the cable is quite frayed, it still works. Last night when I plugged it in before going to bed, I got the power sharing notification, telling me to install the app. I have read several solutions from wiping the cache to factory reset, uninstalling recent apps, cleaning charge port, and replacing the cord and charger as suggested on your site. I have done all of the above except a factory reset. The phone charges but slowly, and more often drains the battery when I plug it in, in the last 24 hours. The only other thing I can think of to do is actually replace the charge port as it is quite old and dirty. I have not had a problem before with other cords or chargers or power packs (battery meant to charge phones) but now it doesn’t seem to matter which I use it still. 

Solution: In this situation, it’s very important that you do a factory reset. Doing so will help you tell if the issue is fixable on your end. If the problem stays after a factory reset (when there are no third party apps installed), you can bet there’s hardware malfunction somewhere. It can be due to a bad charging port, Power Management IC malfunction, damaged battery, or general hardware fault. In this case, you should let Samsung check your phone.

For reference, these are the steps on how to factory reset your S8:

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.
  10. Check for the problem.

Problem #3: Galaxy S8 won’t turn on after do-it-yourself repair

The phone had a cracked screen, so I opened it up and took out the motherboard.  Then I heated up the screen and peeled off all the glass, and sprayed the film underneath the glass with isopropyl alcohol and cleaned it with a toothbrush.  Before applying a new glass, I put the phone back together, but after trying many different button combinations and charging it, all I could get it to do was vibrate and show a blue/red flashing light in the corner.  I don’t know what I did wrong, but any help would be appreciated.

Solution: Hardware problems are best addressed by trained professionals, especially when it comes to top-of-the-line phones like the Galaxy S8. There’s a lot of stuff that must be checked when it comes to hardware diagnostics. The best way to do that is to physically check the logic board. Since Samsung can’t obviously help you in this case, try to bring the phone to an independent technician.

Problem #4: Galaxy S8 won’t turn on after a lightning strike

I was charging my Samsung S8. suddenly there was a thunder strike and after the thunder strike tried to on the phone’s screen, but it does not respond not knowing the whole phone has shut down, since then it does not turn on, and it will not charge until I connect charger to the phone for like 3hours. That’s when it will display battery icon on the screen but yet it won’t turn the device on… Help me out.

Solution: There may be a problem with your phone’s battery. Try to see if you can make it work again first by leaving the phone charged overnight. If the phone does charge but still won’t turn on, that means the battery may be toast. If it’s not a battery problem, other hardware components may be permanently damaged. Keep in mind that fragile electronic devices like smartphones can only take so much energy. If your electrical line was hit by lightning, it may have caused a power surge that damaged your phone. Let a trained professional check the phone so the hardware is examined properly.
