Despite the fact that Samsung is the flagship smartphone of the past, the Galaxy S9 is still susceptible to incidental bugs. If you find that your phone is working slower than when you first removed it from the box, or if you want to sell your device, consider returning it to the factory settings.
A soft or hard reset can fix malware problems or repair corrupted data on your device. To make your S9 work as new again, follow the steps below.
How to reset a Galaxy S9
A soft reset is designed to briefly cut off the power to the phone, as if the battery had been taken out and then replaced (which is handy, since you cannot really remove the battery from a Galaxy S9). The soft reset is a handy way to give your S9 a metaphorical kick when it crashes, malfunctions, or stops responding in other ways. Best of all, this approach does not delete your data, so when you restart your phone, you must still have access to all your info.
Step 2 : Hold down the volume down and Power buttons simultaneously. Place your hands so that you can press both firmly for about 10 seconds. When your phone becomes empty and restarted, you can release it.
Step 3 : wait until the S9 has completely restarted. If necessary, log in again and check whether the telephone works. If you are in the middle of an email or conversation, you may need to restart it. Try to go back to what you did when your phone froze. If the S9 freezes again, you may need to remove that app or take additional troubleshooting measures to find out what goes wrong.
How to perform a hard reset (factory reset) of a Galaxy S9
A hard reset starts your S9 back to the factory settings – the status the phone was in when you first got it. Hard resets are rarely needed, but they can serve different purposes. Some hard resets are a last resort for a phone with serious malware problems or data corruption. The process is also used to prepare the phone for resale or if you want to give it away. We're going to show you how you can do this, even if you can't make your phone respond at all.
Do not get a soft reset and a hard reset together! A hard reset deletes all data on your phone. That includes downloads, contacts, images, and everything else – with SIM and SD card data as the rare exception. This is a very permanent process.
Factory reset protection
If you perform a hard reset to sell or give away your S9, you must also ensure that your Google account is no longer linked to the phone. Factory Reset Protection is designed to prevent thieves from using your phone and you must enter your Google account information even after a factory reset. To remove it, before starting the hard reset process:
Go to Settings> Cloud and accounts > Accounts> Google and then tap the ] Menu and select Delete account.
This will disconnect your Google account from the phone and allow someone else to use it successfully.

How to restore a factory setting for an unresponsive Galaxy S9
If your Galaxy S9 is frozen and you cannot start to respond, you can still try a factory reset with these steps:
Step 1 : Find the Volume Up and the Bixby button on your S9. The volume buttons are on the left side of your phone and the Bixby button is just below.
Step 2 : Hold the Volume up and Bixby hold buttons simultaneously. Hold them down and hold the Power button on the right side of the phone. Now that all three buttons have been held together, the screen of your phone should be blank and an Android logo should appear. This is the sign to release the three buttons.
Step 3 : The phone now displays an update screen. Wait patiently – sometimes this will only take a minute – until the screen switches to the Android system restore menu . You can operate this menu with the buttons Volume up and Volume down and make a selection with the button Power .
Step 4 : Scroll down the menu until you find the option to delete data / restore factory settings (this is one of the blue options on the screen). Highlight this option and then press the Power button to select it. You will receive a big red warning about how this step cannot be undone. If you are sure, mark Yes and select it again with the Volume and Power buttons. Your phone will now restart to the factory settings.
