Step-by-step guide to troubleshooting Galaxy S8+ that’s stuck on the logo

Problem: “Hey guys. I need your help. I bought last week a new Galaxy S8+ phone and now it won’t start up. It is stuck on the Samsung logo and couldn’t go past it. I tried restarting it and it did but it’s still stuck on the same screen. The problem actually started yesterday but I turned the phone off hoping the problem would go away after I let it rest for several hours. This morning when I turned it on it’s still stuck on the logo. Should I bring it back to the store? Thanks guys.”

Troubleshooting: As I said earlier, getting stuck on the logo may mean the phone is suffering from a firmware issue but then there are other possibilities that we have to consider and rule out. That said, here’s what I suggest you do in a bid to fix the problem with your brand new phone or, at least, you would know if you need to have it replaced.

Step 1: Forced Reboot your Galaxy S8+

Forced reboot is necessary for this problem because there’s a chance the problem is caused by a glitch. It refreshes your phone’s memory and drains stored electricity in some of the components. We don’t know yet if this problem is serious or not so we have to assume first that it’s just a glitch. Now, press and hold the Volume Down and Power keys together for 7 seconds and see if the phone boots up successfully. If not, then move on to the next step.

Step 2: Try to reboot your Galaxy S8+ in safe mode

If the Forced Reboot procedure failed to bring the phone back to life, then we have to try to rule out the possibility that some of the third-party apps you installed are the cause of the problem. You have to bring your phone to start in its diagnostic state wherein only built-in apps and core services are running and this is how you do it:

Turn the device off.
Press and hold the Power key past the model name screen.
When “SAMSUNG” appears on the screen, release the Power key.
Immediately after releasing the Power key, press and hold the Volume down key.
Continue to hold the Volume down key until the device finishes restarting.
Safe mode will display in the bottom left corner of the screen.
Release the Volume down key when you see Safe Mode.
Uninstall apps that are causing a problem.

If successful, then it means one or some of the third-party apps is causing the problem. You have to find that app and try to clear its cache and data first and if that won’t work, uninstall it. You may also do that to other apps you suspect is causing the problem.

How to clear app cache and data on Galaxy S8+

From the Home screen, swipe up on an empty spot to open the Apps tray.
Tap Settings > Apps.
Tap the desired application in the default list or tap 3 dots icon > Show system apps to display pre-installed apps.
Tap Storage.
Tap Clear cache.
Tap Clear data and then tap OK.

How to uninstall an app from Galaxy S8+

From the Home screen, swipe up on an empty spot to open the Apps tray.
Tap Settings > Apps.
Tap the desired application in the default list or tap 3 dots icon > Show system apps to display pre-installed apps.
Tap the desired application.
Tap Uninstall.
Tap Uninstall again to confirm.

However, if your phone could not successfully boot in Safe mode, then move on to the next step.

Step 3: Attempt to boot your Galaxy S8+ in Recovery mode

The Android System Recovery environment, also known as Recovery mode, is a fail-safe for phones that have issues with the firmware because even if the firmware fails to boot, it might still be able to start up in this mode. If successful, you should try wiping the cache partition. It has a reset-like effect but none of your files and data will be deleted. If that won’t work, however, then you should proceed with the reset.

How to wipe cache partition on Galaxy S8+

Turn off the device.
Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
Press the Volume down key several times to highlight “wipe cache partition.”
Press the Power key to select.
Press the Volume down key to highlight “yes” and press the Power key to select.
When the wipe cache partition is complete, “Reboot system now” is highlighted.
Press the Power key to restart the device.

How to Master reset Galaxy S8+

Turn off the device.
Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
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).
Press the Volume down key several times to highlight “wipe data / factory reset.
Press Power button to select.
Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
Press Power button to select and start the master reset.
When the master reset is complete, “Reboot system now” is highlighted.
Press the Power key to restart the device.

Step 4: Bring the phone back to the store and have it replaced

If your Galaxy S8+ still cannot boot up successfully after wiping the cache partition or doing the reset or if you encounter other problems after this, then you should bring it back to the store where you bought it and negotiate for a replacement. The technician will probably try to fix the problem but if he fails, then a replacement unit may be provided.

Here are some issues that are similar to the problem we’re tackling in this post. Go through them to see if your concern has some similarities…

Galaxy S8+ won’t bootup

Problem: “Hey guys. I got myself the new Galaxy S8+ and yesterday it seemed like my phone was possessed because it became really slow. I rebooted it and now it’s stuck on the black screen after the logo. I’ve already tried leaving it at that screen for over an hour but it doesn’t turn on completely. Help.”

Troubleshooting: If the problem occurred without apparent reason, then it might be just a glitch. I suggest you try booting it up in safe mode first to find out if it can boot up successfully while all third-party apps are temporarily disabled:

Turn the device off.
Press and hold the Power key past the model name screen.
When “SAMSUNG” appears on the screen, release the Power key.
Immediately after releasing the Power key, press and hold the Volume down key.
Continue to hold the Volume down key until the device finishes restarting.
Safe mode will display in the bottom left corner of the screen.
Release the Volume down key when you see Safe Mode.
Uninstall apps that are causing a problem.

If successful, then reboot in normal mode without doing anything yet. If it gets stuck on the same screen, then you should find the third-party apps that are causing the issue.

On the other hand, if your phone could also not boot up successfully in safe mode, then you should try booting it up in Recovery Mode and if successful, wiping the cache partition may fix the problem. Otherwise, you should do the reset. Here’s how you boot your phone in recovery mode and wipe cache partition:

Turn off the device.
Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
Press the Volume down key several times to highlight “wipe cache partition.”
Press the Power key to select.
Press the Volume down key to highlight “yes” and press the Power key to select.
When the wipe cache partition is complete, “Reboot system now” is highlighted.
Press the Power key to restart the device.

I hope this helps.

Galaxy S8+ keeps turning on and off

Problem: “It’s been a day or so that my phone started to turn itself on and off. I don’t know how much battery is left but I haven’t charged it yet since it started doing this. The thing is, it won’t even respond when I press the Power key to turn it off. It just start up, shows the logo and a second or two after that, it would turn off, vibrate then turn back up again. Do I have to get it replaced?”

Troubleshooting: Replacement should always be considered when a brand new phone like this started to show some issues. In your case, I suggest you try pressing the power button many times to see if you could make it respond. There’s a possibility that the Power key is stuck. If you’re using some kind of enclosure or case, try to remove it and see if the phone still goes into a bootloop. The signs you mentioned are signs of stuck power key but if the problem isn’t fixed on your end, then you should bring the phone back to the store and have it replaced.

Galaxy S8+ stops booting up on logo

Problem: “I’m wondering if you guys have already encountered an issue like mine. My phone is a Galaxy S8+ and today it gets stuck on the S8 logo while trying to turn on. Normally, the S8+ logo would show, then Samsung, then my service provide, it’s not doing that anymore. It only shows the S8+ logo on the screen and stops there. The same thing happens when I try to reboot it. What can I do?”

Troubleshooting: For starters, I suggest you do the Forced Reboot procedure as it may be just a glitch. Press and hold the Volume Down and Power keys together for 7 seconds, the phone may reboot successfully. If not, then try rebooting it in Safe mode, then in Recovery mode.

While in recovery mode, you may try to wipe cache partition and if that won’t work, then I suggest you do the master reset.

Turn off the device.
Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
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).
Press the Volume down key several times to highlight “wipe data / factory reset.
Press Power button to select.
Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
Press Power button to select and start the master reset.
When the master reset is complete, “Reboot system now” is highlighted.
Press the Power key to restart the device.
