HMS Core on Android: why is this application needed and how does it work?

If you have ever looked at the list of installed applications on a smartphone Huawei, Honor or other Android device with services from a Chinese manufacturer, you have probably noticed a mysterious application HMS Core. It does not have a shortcut on the desktop, is not displayed in the application menu, but at the same time it takes up space in memory and is regularly updated via Google Play or AppGallery. What is this app? Why is it installed on your phone? And most importantly, can it be safely removed?

In this article we will analyze in detail what HMS Coreis, how it is connected to the ecosystem Huawei Mobile Services (HMS), what functions it performs and why it has become an integral part of many Android smartphones. You will also learn how to check for its presence on your device, what risks are associated with deleting it, and how to properly manage this service so as not to disrupt the operation of your phone. Let's pay special attention to the differences between HMS Core and Google Mobile Services (GMS) - two competing platforms that determine what applications and functions are available on your device.

Spoiler: if you use a smartphone Huawei or Honor after 2019, then HMS Core is the basis of its software ecosystem. It is not recommended to remove it, but there are ways to optimize the operation of the service, which we will discuss below.

What is HMS Core and why do you need it?

HMS Core (abbreviated from Huawei Mobile Services Core) is a set of system services and APIs developed by the company Huawei to replace Google Mobile Services (GMS) on your devices. After it came under US sanctions in 2019 and lost access to services, the company had to create its own ecosystem to support key smartphone functions: push notifications, geolocation, authorization, cloud storage and much more. Huawei came under US sanctions and lost access to services Google, the company had to create its own ecosystem to support key smartphone functions: push notifications, geolocation, authorization, cloud storage and much more.

In fact, HMS Core performs the same tasks as Google Play Services on "pure" Android devices:

• 🔄 Provides push notifications for applications (analog Firebase Cloud Messaging).
• 📍 Provides access to geolocation services and maps (Huawei Map Kit).
• 🔐 Manages authorization via Huawei ID (analog Google Account).
• ☁️ Synchronizes data with the cloud Huawei Cloud.
• 🎮 Supports gaming services (Huawei GameCenter).

Without HMS Core many applications from AppGallery (official store Huawei) simply will not be able to work. For example, Huawei Health, Petal Maps, Huawei Wallet and even some third-party apps (for example, TikTok or Booking.com in versions for AppGallery) depend on this service.

Important: HMS Core is not a virus or malware - it is an official component of the Huawei ecosystem that has passed security checks. However, its presence may raise questions among users accustomed to Google Play Services, especially if the smartphone was purchased outside of China.

How HMS Core appeared on your smartphone?

There are three main scenarios in which HMS Core may appear on your Android device:

1. Smartphone from Huawei or Honor (after 2019).

   All devices released after May 2019 (when Huawei came under sanctions) are deprived of pre-installed services Google. Instead, it is used HMS Core as the basis for the operation of applications. This applies to series models Mate 30/40/50, P40/50/60, Nova 8/9/10 and newer.

2. Manual update via AppGallery.

   If you have ever installed or updated applications from AppGallery (for example, Petal Search or Huawei Mobile Cloud), then HMS Core could be installed automatically as a dependency.

3. Third-party firmware or "Chinese" versions of Android.

   Some custom firmware (for example, for Xiaomi or Samsung) can enable HMS Core to support Chinese applications. This is also true for devices purchased in China, where Google Play Services replaced by HMS by default.

You can check whether HMS Core is installed on your phone in two ways:

• 📱 Go to Settings → Applications → Manage applications and enter "HMS Core" in the search.
• 🔍 In Google Play or AppGallery find the application by request "Huawei Mobile Services".

HMS Core vs Google Play Services: what is the difference?

To understand why HMS Core is so important for devices Huawei, compare it with the analogue from Google:

Function	Google Play Services	HMS Core
Push notifications	Firebase Cloud Messaging (FCM)	Huawei Push Kit
Maps and geolocation	Google Maps API	Huawei Map Kit / Petal Maps
Authorization	Google Sign-In	Huawei ID
Cloud storage	Google Drive	Huawei Cloud
Game services	Google Play Games	Huawei GameCenter

The main difference is that ecosystem: Google Play Services integrated with millions of applications from Google Playwhereas HMS Core works primarily with AppGallery and supported partners (for example, WPS Office, VLC, Deezer in versions for HMS).

However, HMS Core there are also advantages:

• ⚡ Lower power consumption on devices Huawei (optimized for EMUI).
• 🌍 Better support for Chinese and Asian services (for example, WeChat, Alipay).
• 🔒 Less collection of user data compared to Google (according to Huawei).

⚠️ Attention: If your smartphone initially supported Google Play Services, but you manually installed HMS Core (for example, to access AppGallery), this may lead to conflicts in the operation of notifications or geolocation. In this case, it is recommended to use only one of the platforms.

Is it possible to remove HMS Core and what will happen if you do this?

Technically it is possible to remove HMS Core but the consequences depend on the model of your smartphone:

• 📵 On Huawei/Honor devices without GMS (after 2019):

  Deleting will lead to inoperability most system and third-party applications, including:

  • 📱 AppGallery (you will not be able to install updates).
  • 🔐 Huawei ID (you will lose access to cloud and backups).
  • 📍 Petal Maps and geolocation in other applications.
  • 🔔 Push notifications from instant messengers and social networks.
• 🔄 On devices with GMS (before 2019 or third-party brands):

  If HMS Core was installed manually (for example, for testing AppGallery), removing it will not cause harm, but some Chinese applications will stop working.

If you still want to get rid of HMS Core, do the following:

adb shell pm uninstall -k --user 0 com.huawei.hms

⚠️ Attention: Removal through ADB may lead to malfunctions EMUI. If, after removal, the smartphone begins to slow down or generate errors, restore HMS Core via AppGallery or resetting the settings.

What to do if after removing HMS Core notifications stop working?

If you deleted HMS Core on a device without GMS, then push notifications (for example, from Telegram or Viber) may disappear. They can only be restored by reinstalling HMS Core or switching to alternative instant messengers that support SMS notifications (for example, WhatsApp via an SMS gateway).

How to optimize the operation of HMS Core?

If HMS Core takes up too much memory or uses up battery power, try the following methods optimizations:

1. Limit background activity.

   Go to Settings → Applications → HMS Core → Battery and select "Limit background activity". This will reduce power consumption, but may slow down notification updates.

2. Disable unnecessary modules.

   In some firmware EMUI you can deactivate individual components HMS Core (for example, Huawei GameCenterif you are not playing). To do this:

   Settings → Applications → Show system → [Select an unnecessary module] → Disable

3. Update to the latest version.

   Often bugs with high battery consumption are fixed in new versions. Check for updates in AppGallery or Google Play.

4. Use "Light" mode.

   On some devices Huawei there is an option "Energy saving for HMS Core" in the battery settings.
