Safe Mode is a useful tool for diagnosing issues on your smartphone, as it allows you to isolate the problem and find a suitable solution. 

Understanding the safe mode on your Samsung Galaxy smartphone can be extremely helpful to troubleshoot the device when a problem arises.

This article will provide you with an in-depth guide on what is Safe Mode, how it works, when to use it, and how to boot your Samsung Galaxy smartphone into and out of Safe Mode.

What is Safe Mode?

Safe Mode is a diagnostic mode of a computer operating system (OS) that provides limited functionality to troubleshoot issues related to software and hardware. 

In Android, which is the operating system used in most smartphones such as the Samsung Galaxy smartphones, Safe Mode is a feature that allows the device to run on its most basic functionalities.

In Safe Mode, all the system settings remain the same as they were in the normal operating mode. However, the user interface might appear different due to the absence of third-party widgets and live wallpapers. Users will also notice a “Safe Mode” watermark at the bottom left corner of the screen, indicating that the device is currently in Safe Mode.

How Does Safe Mode Work?

When an Android smartphone is in Safe Mode, the device turns on by loading only the core parts of the OS. This means that only the system applications and services, which are integral to the functioning of the device, are active. All third-party applications, which are the apps that are downloaded from the Google Play Store or other sources, are disabled.

Safe Mode in Android operating systems does this by setting the dalvik.vm.dexopt-flags system property to v=n,o=v. This makes the device ignore the dex files in the /data directory, which is where third-party apps store their data.

The main difference between Safe Mode and the normal operating mode lies in the fact that in Safe Mode, only the apps that came pre-installed on a smartphone are allowed to run. 

The other difference is that the smartphone in Safe mode will operate under default settings, meaning any change made by the user to the smartphone’s settings will not work here.

When to Boot Into Safe Mode?

Safe Mode is used to troubleshoot software and hardware issues in Android smartphones. Since it is a diagnostic mode that operates a smartphone in a basic state, users can isolate third-party apps and custom settings made by them to identify the root cause of an issue.

These are the situations when booting into Safe Mode can be beneficial:

  1. Identifying problematic apps: If your smartphone is freezing, crashing, has slow performance, or battery drain, it could be due to a third-party app.

    Booting into Safe Mode will help you identify if the problem is caused by a third-party app or not, as these apps will not run in this mode.
  2. Preventing malware: If you suspect that your smartphone has been infected with malware, booting into Safe Mode can prevent the malware from causing further damage, as it disables third-party processes.

How to Boot Your Samsung Galaxy Smartphone into Safe Mode

The process of activating safe mode can slightly differ depending on the model of the smartphone. 

Since our website is mainly about Samsung Galaxy smartphones, we will explain how to boot a Samsung Galaxy smartphone into recovery mode.

FAQ

Here are the answers to the most asked questions regarding the Safe mode on Samsung Galaxy smartphones.

Is Safe mode the same as the Secure boot?

Safe mode is not the same as Secure boot. Secure boot ensures that the boot process of an Android device is not interfered with and only verified/authorized software is loaded during the boot process.
On the other hand, Safe mode is a diagnostic mode that only allows system apps, and services, to run under default settings.

Is Safe mode and Emergency mode the same?

Safe mode is not the same as Emergency mode. The emergency mode makes the system run under minimal possible battery power to conserve battery for emergency situations.
On the other hand, Safe mode doesn’t follow any restrictions to conserve battery power. Its purpose is to serve as a diagnostic mode to isolate system apps and default settings to identify software/hardware problems of the device.

Is safe mode dangerous?

Safe mode is not dangerous. Safe mode isolates the system services and apps, allowing users to identify if the problem is caused by a third-party app or misconfiguration in system settings.
Therefore, Safe mode is not dangerous and is actually there to troubleshoot a smartphone.
