The #Samsung #Galaxy #S8 is a flagship phone released last year which departs from the usual flagship design of previous generations. This is the first model that ditches the physical home button which is actually good since it allows the phone to have a larger 5.8 inch Super AMOLED display. This device uses the Snapdragon 835 / Exynos 8895 processor which when combined with its 4GB of RAM allows apps to run smoothly. Although this is a solid performing phone there are instances when certain issues can occur which we will be addressing today. In this latest installment of our troubleshooting series we will tackle the Galaxy S8 screen went black is unresponsive issue and other related problems.
S8 Screen Went Black Is Unresponsive
Problem: Using a refurbished, unlocked galaxy s8–have had the phone 3 weeks. Yesterday, after a phone call in my car, I attempted to play music from my phone via bluetooth to the car. The phone screen went black and became unresponsive. Only thing I could think of that may have caused the issue was one of two things: 1) I downloaded Samsung’s music player app earlier in the day to play music through. 2) My son was playing a game on my phone and perhaps an add screen came on and he hit something. About 2 hours later, when I was somewhere I could troubleshoot, I did the soft reset and the phone came back on (I had to hold the keys for about 30 seconds or more–holding for only 7 to 10 seconds didn’t work). I thought the phone was fixed. A couple hours later, the phone went into an auto-restart loop while I was using the reddit app (which I have been using since I first set-up the phone, with no issues). It did it a few times before coming on and staying on. I restarted the phone in safe mode and didn’t experience any issues. I downloaded Norton’s anti-virus app–thinking that if my son DID accidentally hit something during a game, maybe there was some sort of malware or something causing the issue. I turned off safe mode from the notification panel, which turned the phone off–I thought it was restarting; however, the start screen never appeared and the screen remained black. The only difference from the earlier black screen is that the blue notification light was on, flashing slightly, but never going out completely. After this, I tried doing a forced restart and the screen would not come on. I read that it could take seconds or minutes of holding the vol down key and power button to get this to happen, so I tried several times for various amounts of time (longest was about 3 min). The only thing that would happen was the blue notification light would flicker once, every 10 seconds while holding down the buttons. At this point, I decided to plug it in and go to sleep. This morning, phone is in the same state–black, unresponsive screen with constant blue notification light. No sounds, no vibration feedback, nothing. Forced restart still not working. I tried starting the phone in recovery mode and that is not working either. Lastly, plugged phone into charger and let sit for more than 10 min before trying the forced restart, again, and nothing but the slight blue notification light flash every 10 seconds. Not sure what to do at this point. I’ve googled the issue and can’t find any information about what to do if none of these options works. I assume I may need to send my phone back since it is under warranty, but am concerned about getting my photos and videos off it. If there are any other possible solutions, please let me know.
Solution: The first thing that you need to do in this case is to make sure that the phone battery has sufficient charge. Follow the steps listed below to charge your phone.
- Remove the microSD card of the phone if you have one installed.
- Clean the charging port of the phone using a can of compressed air.
- Charge the phone for at least 20 minutes using its wall charger.
- In case the phone doesn’t charge then try using a different charging cord and wall charger. You should also try charging the phone from a computer USB port.
Once the battery has sufficient charge then do a soft reset. This is done by pressing and holding both power and volume down buttons for at least 10 seconds.
If the phone still remains unresponsive then you need to have this checked at a service center as this could already be caused by a faulty hardware component.
S8 Black Screen With Notifications Working
Problem: My battery run off of juice from 50% to zero within 10 min. I attached my phone to my fully charged power bank and the screen didn’t show up charging symbol. I waited for some time. Did a soft reset which switched in again. I did this process few times. I tried to charge it normally in socket, actually solar panel socket as I have been doing last month. After hour or so of charging. I switched my phone on. I could again hear it starting, but the screen was still black. Even the logo didn’t show up as before. I could have heard my FB msg beeping as have been received. I tried again switched it off and on few times, soft reset out for few minutes. Still same problem persist. It is a year old phone. The battery last around 10h only for long time. Last month I have been in a place where I have little reception. Battery got lots of work just by trying to find the reception. I was charging my phone mostly from my power bank which has been charged via solar panel in last month. I am far away from repair shops to find out what is wrong. It has happened several tires before that my phone showed black screen but it got sorted itself before.
Solution: It looks like the phone has a battery and display problem. The best thing to do right now is to start the phone in recovery mode. If the screen works in this mode then you will need to do a factory reset. Take note that the reset will erase your phone data.
In case the above step fails to fix the problem then it’s time to bring the phone to a service center and have it checked.
