What is com.android.incallui and com.samsung.android.incallui?

Many users have expressed concern about a system application called com.android.incallui or com.samsung.android.incallui running in the background. They aren’t sure if it is an essential app like com.osp.app.signin and DiagMonAgent or just the usual Samsung bloatware like KLMS Agent.

This article explains what is this app, what does it do, why does it come pre-installed on your phone, and how to fix common issues related to this app.

What is com.android.incallui?

com.android.incallui is a pre-installed Android app package that contains the User Interface (UI) data of your phone’s Call dialer app. It acts as an interface between the phone’s call screen and the backend machine. When you call a person, the elements you see in the call screen for user interaction are stored in the com.android.incallui app.

Some of the elements that you’ll usually find in the User Interface(UI) of a call screen are: Disconnect Call button, Speaker button, Hold button, Record button, Keypad button, Mute button, Contacts button, Add Call button, Video Call button, etc.

When you press a button on the call screen, the com.android.incallui process is activated and it registers your command in the backend machine.

Every calling app requires the com.android.incallui system app for making calls from your phone. If you don’t have this User Interface app then you can’t use calling apps. This app comes pre-installed on all Android devices and it is a system app.

What is com.samsung.android.incallui?

com.samsung.android.incallui contains the User interface (UI) of the call screen app in Samsung smartphones running on Android OS.

Every app in an Android device contains a package file that is represented as com.companyname.android.appname. So, the package file you see as com.samsung.android.incallui is nothing but the User Interface(UI) of the call screen app in Samsung devices that contains elements for user interaction like disconnect call, mute call, hold call, etc.

What is User Interface(UI)?

User Interface(UI) is the design that allows interaction between a user and product to perform some kind of task through an interface. For example, in WhatsApp, all of the elements that you see on the screen like chats, contacts, call button, video call button, menu button, settings, etc, are part of the User Interface.

An example of Hardware UI could be a Remote or Gamepad. The design of the remote or gamepad with all the buttons, navigational elements, etc. is part of the User Interface.

Is IncallUI used for Cheating?

Some people think that IncallUI is an app used to cheat on their partners just because the app doesn’t appear in the App Drawer and has the term “call” in it. This is totally False.

IncallUI contains the User Interface(UI) of a phone’s call app and it doesn’t have anything to do with cheating.

What is IncallUI spy?

There is no such app available on the Internet called IncallUI spy. Some people believe that InCallUI is spyware that spies on users’ data and sells it to third parties but that is also False.

A few Android users believe that IncallUI is a virus or bloatware but that is not true. It is not a virus, spyware, or bloatware.

The com.android.incallui system process doesn’t consume system resources when your phone is not used for calling or receiving any phone calls but, whenever you call someone or receive a call this app starts consuming your CPU and RAM and that is when the battery draining happens.

You can prevent this app from draining your battery by limiting your phone calls.

What is the “Unfortunately IncallUI Has Stopped” error?

A lot of users have complained that the IncallUI system app stops responding and they get an error message “Unfortunately IncallUI has Stopped.” This error message prevents users from using the dialer app to call another person and receive calls from others. This happens with all manufacturers like Samsung, OnePlus, Xiaomi, LG, Vivo, Oppo, etc.

This error message occurs due to Corrupted Cache data. If you don’t clear the IncallUI system app cache for a long time, the cache data becomes corrupted and causes the app to misbehave and you get the “IncallUI has stopped” error messages.

You can fix this problem by clearing the app cache data which has been mentioned below in detail.

How to Fix the “Unfortunately IncallUI Has Stopped” error?

As I mentioned earlier, this error message is a result of corrupted cache data and it can be fixed by clearing the IncallUI system app cache. You can clear the cache data for this app by following the steps mentioned below.

Step 1 – Go to Settings.

Step 2 – Tap on Apps.

Step 3 – Tap on the Ellipsis icon (3 vertical dots) in the upper right corner.

Step 4 – Tap on Show System Apps.

Step 5 – Search for com.android.incallui and tap on it.

Step 6 – Tap on Storage.

Step 7 – Tap on the Clear Cache button.

If clearing the app cache didn’t fix this error then, you need to check your software version. Sometimes, this error message can appear if you didn’t update your phone’s software for a long time.

To check for software updates on your device follow the steps below.

For Samsung Android devices

Step 1 – Go to Settings.

Step 2 – Tap on Software Update.

Step 3 – Tap on Download and Install.

Step 4 – Your phone will check for new software updates. If a software update is available then download and install it.

If no update is available then it will show “Your software is up to date.”

For other Android devices

Step 1 – Go to Settings.

Step 2 – Tap on About Phone.

Step 3 – Tap on Software.

Step 4 – Tap on Check for Updates. If a new update is available then download and install it.

If no update is available then it will show “Your software is up to date.”

If the error message still appears after updating the software, then there is a problem with your native calling app. In that case, you will need to download a third-party calling app like Google Phone, Drupe, or Contacts+.

All of these apps are great alternatives for your native calling app and installing any one of these apps will remove the “Unfortunately IncallUi has stopped” message.

Can you Disable com.samsung.android.incallui?
