How to reset memory on Android: all methods from simple to complex

Resetting the memory on a smartphone Android is a radical, but sometimes necessary step to return the device to performance, remove viruses, or prepare for sale. Many users are afraid of this procedure, fearing they will lose important data or completely “kill” the gadget. In fact, full reset (factory reset) is a standard operating system function provided by manufacturers to restore performance.

In this article we will analyze all existing methods of resetting memory - from software soft reset (soft reset) to hard reboot (hard reset) via the recovery menu. You will learn how to properly prepare the device, what data can be saved, and what to do if you have a smartphone stuck on the logo after an unsuccessful reset. We will separately dwell on the nuances for devices Samsung, Xiaomi, Huawei and other popular brands, where the process may differ.

When need a memory reset on Android

Before taking drastic measures, it’s worth understanding whether your device really needs a complete wipe. There are several clear reasons for resetting:

• 🐢 The smartphone became slow down for no apparent reason (applications take a long time to open, the animation “lags”, the device overheats).
• 🦠 Suspicion on virus infection —unfamiliar advertising appears, unknown applications appear, traffic is consumed in the background.
• 🔄 Before sale or transmission the device to another person (even after deleting files manually, data can be restored).
• 🔧 After an unsuccessful firmware updates, when the system malfunctions or does not start at all.
• 📱 Malfunctions sensors (touchscreen, camera does not work, speaker) after installing third-party applications.

However, resetting is not always a panacea. For example, if the battery quickly discharges due to wear and tear, and not due to background processes, or if the smartphone is physically damaged (it fell into water, the screen broke), then clearing the memory will not correct the situation. In such cases, it is better to contact a service center.

⚠️ Attention: On devices with root access or custom firmware (LineageOS, Pixel Experience), a reset can lead to loss of performanceif the kernel or recovery are modified. Before the procedure, check the compatibility of your firmware with factory reset.
