The Galaxy S7 and the S7 Edge are a few years old, but given their impressive hardware, there should be no reason to slow down or freeze. However, if your Samsung Galaxy S7 or S7 Edge shows signs of slowing down, it may be due to a malware-infected app.
Fortunately, resetting your Galaxy S7 to factory settings is one of the most effective ways. Fix problems and restore the original state of the device. Just follow the steps below to find out how to clean up your S7.
Factory Reset Protection (FRP)
This is very important:  You must disable FRP before you delete your smartphone when you sell it or this device want to pass on another person . If you do not, the following message appears on the screen:
"This device has been reset. Sign in with a Google Account that was previously synced on this device.
In this case, you will need to provide your password to the new owner, and nobody wants to do this.
How to Disable FRP
- In the Settings go to Disable Screen and Security and remove any passwords, patterns, or PINs. Everything under Screen Lock needs to be removed.
- Open Settings Go to Cloud and Accounts> Accounts and tap Google Tap the menu (three dots) top right and select Remove Account .
- If you have removed all accounts from your device, you can reset your smartphone.
Now you are ready to delete your smartphone. Remember, as shown on the screen, all your data will be erased and your phone will be completely erased until the day it came out of the package.
There are two types of resets. You can reset the factory settings to the recovery mode by using the settings menu or the hardware buttons. Let's take a look at the easy way.

How to Reset Factory Defaults Using Recovery Mode
It may happen that you can not get your S7 boot properly. It may be due to an update or other software issue that prevents the system from booting or puts the device into a boot loop. In this case, you can use the hardware buttons to reset using the Android recovery menu. This is similar to pressing F8 when booting Windows. It requires us to turn on the smartphone in a specific way to access the recovery mode menu.
- With your Galaxy S7 turned off, press and hold the buttons Power, Home and Volume Up simultaneously.
- Hold Power, Home, and Volume Increase until the top of the screen Recovery Booting is displayed (in the case of my Exynos S7, a dancing Android robot ). When you see this, you can release the buttons.
- Wait a moment while the recovery mode starts. If you are in Recovery Mode, a list of options is displayed.
- Scroll down the Volume Decrease key until Clear Data / Factory Reset is executed is highlighted.
