What is the FaceService App on Samsung Android Phones and What is it Used For?

The FaceService system app analyzes all the photos in the Samsung Gallery to detect human faces using Samsung’s built-in face detection technology. Once FaceService identifies that the photo contains a face, it shows a button that allows users to add name tags to the photo and create a People Album of similar photos by selecting the name tag.

FaceService App info

Modern Android devices including Samsung have face detection and recognization technology. The face recognization technology is used for unlocking smartphones using the face unlock feature whereas the face detection technology is used to detect faces in pictures saved in the Gallery.

When you click a photo and save it in the Gallery, the FaceService app can detect whether it’s a human face or not. If it identifies a human face then it provides a “People” option as shown in the image below.

When you tap the “People” option, a popup window appears where you get an option to add a name tag to the face and your relationship with the person in the photo. Once you add a name and tap “Save”, this name will appear near the face of that photo.

If you tap twice on that name, you’ll be shown all the photos with that person’s face on them. Once you add a name tag, the FaceService app automatically adds that name tag to all the similar photos that have that person’s face. The app also sorts these photos inside a People Album with the person’s name tag.

The package name of the Samsung FaceService application is com.samsung.faceservice. This app is similar to another system app in Samsung devices called SmartFaceService. The SmartFaceService also detects human faces in images saved in the Samsung Gallery.

FaceService Has Stopped?

A lot of users have complained that the FaceService app keeps stopping frequently. When it stops working, an error message pops up that reads “Unfortunately FaceService has stopped” or “FaceService has stopped working.”

Here are the reasons why the FaceService app stops working:

1. Corrupted or Overloaded Cache Files – If you don’t clear the app cache for a long time the cache files become corrupt. The cache file storage folder has limited storage space so when the size of the cache files becomes more than what could be stored, the cache files become overloaded and cause the app to malfunction leading to these error messages.

2. Issue With the FaceService App – If there is an internal issue with the FaceService app where it is having trouble using the face detection technology then it could stop the app from functioning properly.

3. Firmware issue – The app could also stop working if there are you’re using outdated Firmware or there are issues with your device’s Firmware. It may also happen if you’re using a Custom Firmware instead of the Stock Firmware.

FaceService Consuming Too Much Battery

The FaceService app continuously runs in the background to detect faces in the photos stored in the Samsung Gallery. As you add more photos to your Gallery, the FaceService app will take more time and resources to identify faces in the photo and this will cause higher battery consumption.

When the FaceService app is analyzing your photos, the battery usage hovers around 12% to 15% which is more than what the Android System consumes normally. If there are a lot of photos in the Gallery then FaceService will cause very high battery consumption and its battery usage will remain high for a long period.
