Solved Samsung Galaxy S8 Screen Is Black And Unresponsive After Software Update

The #Samsung #Galaxy #S8 is a flagship phone released last year which uses the new design that’s also being adopted by the S9. The phone does not have any physical home button making it possible for the device to have a 5.8 inch Super AMOLED display. It’s also quite capable of handling anything thrown at it thanks to its Snapdragon 835 / Exynos 8895 processor combined with 4GB of RAM. 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 is black and unresponsive after software update issue and other related problems.

S8 Screen Is Black And Unresponsive After Software Update

Problem: Hi, I have a Galaxy S8, not sure of the android version, recently on July 4th the original carrier for my phone installed a software update like usual. My phone worked fine immediately after and showed no signs of freezing and no trouble charging. Although the night after my screen went black and became unresponsive to me holding the power button and my attempts at charging it. I have used both the wall charger and a wireless charger but no LED lights turned on. The wireless charger indicated that it recognized my device and was charging but the phone was still unresponsive even when I left it there overnight. I have tried holding the power button and the volume down button but the phone is still unresponsive. When I plugged my phone into my laptop it made a very quiet buzzing sound (not sure if that’s relevant). What can I do now?

Solution: The first thing that you will want to do in this particular case is to make sure that the battery has sufficient charge. In this case since the phone responds to charging using a wireless charger then I suggest you use this. Once the battery is charged follow the troubleshooting steps listed below.

  • Remove the microSD card of the phone if you have one installed.
  • Perform a soft reset. This is done by pressing and holding both power and volume down buttons for at least 10 seconds.
  • Try starting the phone in recovery mode. If the screen works in this mode then the problem could be caused by a software glitch. You will then need to perform a factory reset in this mode. Take note that the reset will erase your phone data.

If the above steps fails to fix the problem then you should bring the phone to a service center and have it checked.

S8 Battery Gets Hot After Phone Got Wet

Problem: My Samsung Galaxy S8 was on the kitchen counter and got water splashed on it.  It wasn’t submerged or anything but ever since, it’s been acting wonky. The battery will get very hot (almost untouchable hot) but doesn’t drain fast.  It is navigating around the phone opening & closing apps on it’s own. Makes it almost impossible to use for any length of time. I took it to a cell phone repair shop.  They checked for water damage & found none. They also thought it might have something to do with the lock screen. Took off the password protection as recommended, didn’t help.  I did a factory reset. It worked like new until the battery got hot again (which took a few hours after the reset), now we’re back to the same problems. I’m wondering if it could be the battery itself.  But seeing as I can’t access the battery, I’m looking for some thoughts before I pay to have the it replaced. And doing factory reset every time isn’t an option either. Any help would be greatly appreciated.  Thanks

Solution: Although this phone has a waterproof feature there are still instances when water can enter the phone. The best thing that you can do in this case is to place the phone in a bag of rice for at least 48 hours. The rice will absorb any moisture present in the phone. After 48 hours have passed clean the charging port of the phone using a can of compressed air then charge the phone for at least 20 minutes using its wall charger. Once this is done turn on the phone, backup your phone data then do a factory reset. Once the reset is complete do not install any apps in your phone just yet. Remove the microSD card if your phone has one then check if the problem still occurs. If it does then this is most likely a hardware related problem already possibly caused by a faulty battery. You will need to have this checked at a service center.

S8 Moisture Detected Error After Getting Wet From Sea Water

Problem: Hi, unfortunately my son dropped his Galaxy S8 (which we bought in May) in sea water yesterday… since then a message appears on the screen stating a moisture detected error thus the phone cannot be charged. We have tried to dry it by putting in a box filled with rice and by fanning with cool air but to no avail. Apart from that message and the inability to charge it everything seems to work fine. Is there anything we can do? I’m furious at him and he can’t stop crying

Related Problem: My samsung s8 fell in in very little water in a bowl. Now when it shuts down because of 0% battery and i connect the charger is say moisture detected and i have to charge it a little bit from wireless charger and rest with normal charger, but if i connect the charger while phone is still on and have some charging it works perfect, no message displays.

Solution: The best thing that you can do right now is to make sure that the charging port of the phone is dry. Use a mini vacuum or a hair dryer to clean the port. You should also try wiping the port using a tissue so that any moisture present in it will be removed. Once this is done try checking if the error message still appears. If it does then you will need to check if the problem is caused by a software glitch by doing a factory reset. Take note that the reset will erase your phone data.

In case the above steps fails to fix the problem then you will have to bring the phone to a service center and have it checked.
