A factory reset, also known as a hard reset, is the process of restoring an electronic device to its default factory settings. This typically involves erasing all data, apps, and settings from the device and reinstalling the operating system. Factory resets are often performed when a device is experiencing problems, such as software glitches, persistent errors, or slow performance. Performing a factory reset can potentially resolve these issues by restoring the device to a known good state.
Factory resets can also be useful when selling or giving away a device, as they can help to protect your personal data from being accessed by others. Additionally, factory resets are sometimes performed to free up storage space or to remove malware or viruses from a device.
