At some point, you’re probably going to have to reset your Samsung Galaxy S8+ smartphone. When it’s frozen and not responding, you will want to soft reset it. If you are having major issues with the device that normal troubleshooting doesn’t fix, you may want to hard reset it to factory defaults. Here’s how you can do both.
Soft Reset
Whenever the device is frozen or doesn’t respond to commands, simply press and hold the “Power” and “Volume Down” buttons on the device for about 10 to 20 seconds. Eventually, the screen should turn off. You will then be able to turn the device back on and resume normal operation.
Hard Reset
There are two ways you can perform a hard reset on the Galaxy S8. One procedure can be done from startup, the other from within the Android OS. These steps will wipe all data from the device, so be sure to have a backup in place if you wish to keep your data. Also, if you have encrypted the data on your SD card, be sure to disable encryption before these steps. Otherwise, you will never be able to view your encrypted files again.
From Android OS
- Tap “Settings” > “Backup and reset” > “Factory data reset” > “Reset” > “Delete All“.
From Startup
- With the device powered off, press and hold “Volume Down“, “Bixby” and “Power“.
- Continue to hold both buttons until you see the Recovery screen.
- From the recovery screen, use the “Volume Down” button to toggle the selection to “Wipe data / factory reset“.
- Press the “Power” button to select the highlighted option.
FAQ
How do I disable Factory Reset Protection?
Factory Reset Protection prevents access to your device without your permission. It locks the device to your Google account. If you’re changing ownership of the phone, you will want to turn this feature off.
You can disable Factory Reset Protection by removing your Google account from the device before the factory reset. This can be done under “Settings” > “Accounts and cloud” > “Accounts” > “Google” > select the account > 
> “Remove account“.

How can I start up my phone without touching screen
Galaxy s8 soft reboot—volume down then power for about 10 seconds — phone vibrates once and screen flashes on then off (very fast screen flash) then nothing. Holding all three buttons down i can get into the mode where I could download a custom OS mode (blue screen with warning), phone says to cancel this screen and reboot press the volume down button. Pressing / holding volume down button returns the phone to black.
Reboot with the 3 buttons doesn’t work how do we get the phone back please ????????
Christina. Place your phone in a container and put rice around it.

@janna there are several youtubers that work on phones that have the technology and means to fyi this easily. If you each out to any popular android technician youtubers they would study do this for free.
My Galaxy S8 is the least stable of 3 other Samsung phones that I have used. It has a few issues for sure.
@Janna – Maybe check to see if he had a Samsung Cloud account where the photos were synced. Is there an SD Card inside the phone? You can perhaps eject it and see if the pics are on the card using another device.
Otherwise, follow these tips https://www.samsung.com/ca/support/mobile-devices/what-can-i-do-forget-screen-lock-password-pin-pattern-galaxy-a5-2017/
My boys dad passed away in March. We just received the phone back from police and would like to get pics off, as they are the most current pictures of the three of them together.. Although I have his log-in’s for everything, we don’t have his phone access code. We are down to 4 tries before it factory resets and we loose everything so we are stuck. Verizon suggested signing into Google Photos, which we did, but he must not have ever gone onto that because nothing is in there, so we struck out. We are at a loss and don’t want to have all the photos deleted. This is so important to my kids. Any suggestions on what we can do? Appreciate it very much.
Since last update my s8 doesn’t show all text message conversations. You have to press down on the last message just to view that message. I have tried everything. Please help
