What is RcsSettings?

RcsSettings is a built-in system application that allows users to control the settings of the Rich Communication Services(RCS) on Samsung Android devices from the Samsung Messages app or Google Messages app. RCS is a communication protocol between mobile network operators(carriers) and between the smartphone and the carrier network.

The application package name of the RcsSettings.apk file is com.samsung.rcs. This app is exclusive to Samsung devices and is directly related to the Rich Communication Services(RCS) on your Android device.

In this article, I’ll explain more about the RcsSettings app, what is it used for, and is it safe to disable/uninstall this app.

What is RcsSettings Used For?

The RcsSettings app allows you to enable/disable as well as adjust the settings for the Rich Communication Services(RCS) on your Samsung Android device. RCS is designed to improve the messaging experience on Android devices by replacing the traditional SMS/MMS messages with a more complex messaging service that allows the transmission of multimedia files and provides phonebook polling(for network service discovery).

RcsSettings app details

It is considered a part of the broader spectrum of the IP Multimedia Subsystem also known as IMS Service.

RCS is present on the default Google’s Messages app and some other messaging apps like Samsung Messages where it is known by the name Chat. RCS provides several features including text messaging, photo and video sharing, message typing indicator, Read Receipts, group chats, video calls, location sharing and file transfers.

RCS can be considered the Android equivalent of the iMessage app on Apple iOS devices. It is designed to provide the same features similar to other internet messaging apps like WhatsApp, Messenger, LINE, HIKE, etc. Sending messages using RCS requires cellular data but you can also send them using Wi-Fi.

What Permissions Does RcsSettings Require?

RcsSetting only requires Phone permission that allows this app to read your phone status and identity. You can check the permissions required by going to Settings > Apps > Show System Apps > RcsSettings > Permissions.

Every Android app requires Permissions to operate on your device. If you don’t accept the permissions then the app won’t function.

Is the RcsSettings App Safe?

Yes, the RcsSettings system app is totally safe. It is a preinstalled system application so it cannot be a virus or spyware. It doesn’t cause any harm to your device and it also doesn’t have any spying capabilities.

RcsSettings is a safe application that allows you to control or adjust the settings of the Rich Communication Services on your Android device. It doesn’t use your cellular data or system resources unnecessarily so it is not bloatware also.

Some users are concerned about the security of this app but let me assure you that the RcsSettings app cannot be used to hack your conversations on the Samsung Messages app or Google Messages app. The messages are encrypted and totally secure.

Can You Uninstall RcsSettings?

You can uninstall the RcsSettings system app using the Android Debug Bridge(ADB) software or using an application called System App Remover but this method requires you to root your Android device.

If you use the Chats feature on Samsung Messages or Google’s Messages app then you shouldn’t uninstall this app because removing it won’t allow you to control the RCS settings on your device and you might not be able to use this feature.

Users who don’t use the Chat feature can uninstall this app from their device. Below you will find the two methods to uninstall this app.

RcsSettings Draining Battery?

The RcsSettings app does use your cellular data and system resources when you’re sending and receiving Chat messages so there is some battery consumption but it’s minimal. This is not enough to drain your battery quickly.

If you’re noticing high battery consumption, you should use a Wi-Fi network instead of cellular data to send Chat messages and you can also cut down the usage of the Chat feature on Samsung Messages or Google Messages app to reduce battery consumption.

If that doesn’t solve the problem, you could disable the app using a Package Disabler app like BK Disabler.
