Method 1: Factory reset the device from the Settings menu
Factory resetting the Samsung Galaxy Note 4 using its Operating System, a procedure known as a ‘soft reset’, is the simplest way to reset the device to factory settings. Factory resetting any device clears any data stored on the device’s internal memory, so a person should make sure that they back their device’s internal memory up before attempting a reset.
Method 2: Factory reset the device through Android System Recovery
The other method that can be used to reset the Samsung Galaxy Note 4 is referred to as a ‘hard reset’ and involves the use of the Android System Recovery menu. A hard reset should be used when the device’s Operating System is unresponsive or the user desires a thorough factory reset of the device.
