Solved Samsung Galaxy S8 Shuts Down When Screen Mirroring After Oreo Update

The #Samsung #Galaxy #S8 is a flagship phone released last year that uses a new design approach when compared to the previous flagship phones of the company. The first thing that you will immediately notice is its massive 5.8 inch Super AMOLED display which is made possible since the phone no longer has a physical home button. It uses the Snapdragon 835 / Exynos 8895 processor combined with 4GB of RAM to provide a smooth user experience. 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 shuts down when screen mirroring after Oreo update issue and other related problems.

S8 Shuts Down When Screen Mirroring After Oreo Update

Problem: Since I updated my S8 to android 8 recently I have been unable to watch anything on smart view without it shutting down after about 20 minutes. I have tried screen mirroring and this is just the same. Before the update I was able to connect to my smart tv no problem. Now it has become annoying. Is there any way I can revert back to android 7?

Solution: Unfortunately there is no automated way to revert back to the Nougat operating system as you will have to manually flash the firmware back to your phone. The good news is that this problem can easily be fixed with some software troubleshooting. The first thing that you will need to do in this case is to check if the issue occurs in Safe Mode. if it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it. If the issue still occurs even in Safe Mode then you will need to backup your phone data then do a factory reset. The reset will remove any traces of old software data present in your phone which is usually the culprit in many phone issues that occur right after a software update.

S8 Becomes Unresponsive

Problem: I have a Galaxy S8 , I’ve read your articles, and I’m not finding a fix. I’ll be on my phone with considerable battery life, and it will stop responding. Nothing works, the screen will dim, and then go black since it thinks I’m not hitting any buttons. At this point the only way to get away from this is to soft reset. After about 10 seconds I feel a small vibration once. Then if I hold down the power key only, after 10 seconds it turns back on. It’s happened when I’m using different apps, etc so there is no pattern there. It happens once every day or two during the last few weeks (right after I updated the software. I had one more software update a few days ago, so it was 2 updates ago if that helps). I figured it was the update as I got the phone brand new at the end of January. Have you heard about this, nothing is coming up on my online searches and I’m assuming it’s because it’s new. Any help would be greatly appreciated!!

Related Problem: Hello, My Galaxy S8 Active has been acting odd the past few days, it has twice now gone black on the screen and vibrates when I touch the home button location, and it fixes when I reset but each time I reset it, it would take me to different things such as a reboot screen but today it had a do you want to download this OS and I said no and asked to restart I’m not sure what is happening and would really appreciate the help.

Solution: What you will need to do in this case is to check if the problem is caused by a software glitch. To do this you need to remove the microSD card of the phone ( if you have one installed) then start the phone in Safe Mode. When the phone operates in this mode only the pre-installed apps are allowed to run. If the issue does not occur in this mode then it is most likely caused by an app you downloaded. Find out what app this is then uninstall it.

If the issue still occurs in Safe Mode then the next step is to backup your phone data then start the phone in recovery mode. From here you will need to wipe the cache partition of the phone followed by a factory reset.

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

S8 No Network Available

Problem: I have a Samsung Galaxy S8 It’s not letting me look at available networks or any info I go to my settings into stays then sim card status and absolutely everything says unavailable. I’m not even 100% on who the original cell provider is. I’ve been fighting with this for months now and I have a Koodo sim card I had tried someones old Fido and it would work but the number associated with it has been disconnected long time ago. What can I do

Solution: The best thing to do right now is to backup your phone data then do a factory reset. Once the reset is complete try checking if the issue still occurs. If it does then try getting a new SIM card in your phone. You should also make sure that you are in an area with a good signal reception.

If the above steps fails to fix the problem then your phone might be locked to a particular network. Try dialing *#7465625# then when a menu appears (Network lock,  Subset lock, SP lock) check if all levels are in the on position. If they are then your phone is network locked in which case you will need to get this unlocked.

If your phone is unlocked then you should bring this to a service center and have it checked.
