How to disable unnecessary applications on Android: complete guide

Smartphones based on Android are often overloaded with pre-installed applications that take up precious memory space, consume battery power and slow down the device. Even after purchasing a new gadget, users are faced with dozens of unnecessary services - from duplicate browsers to branded utilities from the manufacturer. But not everyone knows that most of these applications can safely disabled or even be removed without risk to the system.

In this article you will find proven methods for cleaning Android from digital garbage: from standard deactivation methods through settings to advanced techniques using ADB and superuser rights. We will also look at which applications cannot be touchedso as not to disrupt the stability of the smartphone, and give recommendations for optimization after cleaning.

Before you start deleting, it is important to understand the difference between user and system applications. The former are installed from Google Play and removed in the standard way, while the latter are integrated into the firmware and require a special approach. Incorrect actions can lead to interface failures or even bricking of the device - so follow the instructions carefully.

1. How to determine which applications can be disabled

Not all pre-installed apps are equally useless. Some of them are critical for operation Android, while others are just marketing ballast from the manufacturer or telecom operator. To avoid making mistakes, follow this algorithm:

Step 1: Usage Analysis.

Go to Settings → Applications → All applications and sort the list by size or time of last use. Pay attention to apps that:

• 📦 Take up more than 100 MB memory, but have never been opened;
• 🔄 They automatically start when the system starts (check in Settings → Battery → Battery usage);
• 📱 They have the manufacturer's brand in the name (for example, Samsung Knox, Xiaomi Cloud, Huawei AppGallery).

Step 2: Checking dependencies.

Some applications seem unnecessary, but are actually part of the ecosystem. For example, Google Play Services cannot be disabled - this will lead to the collapse of most services. GoogleBut duplicate browsers (Chrome + Samsung Internet) or music players can be safely deactivated.

Step 3: Testing before deleting.

Before getting rid of the app, disable it for 1-2 days. check if there are any malfunctions in the smartphone. If everything works fine, you can delete it.

Method 2: Uninstall with root access

If you have root, use file managers like Root Explorer or FX File Explorer:

• 📂 Go to the folder /system/app or /system/priv-app;
• 🗑️ Find the folder with the name of the unnecessary application (for example, HwGameCenter na Huawei);
• 🔄 Rename the folder, adding at the end .bak (for example, HwGameCenter.bak);
• 🔄 Restart the device.
