What is com.sec.epdg and How to Fix com.sec.epdg has Stopped Error?

There has been a lot of confusion in the Android community about the com.sec.epdg app. Android users aren’t sure if it is an important system application like com.android.incallui or just the usual Android bloatware.

There isn’t much information about this app on the Internet which is why I have written this article to explain everything about com.sec.epdg and how to fix com.sec.epdg has stopped error.

What is com.sec.epdg?

com.sec.epdg is the Android Package name(APK) of the system application named Evolved Packet Data Gateway (ePDG) which is a critical component of the 4G mobile core network, called the Evolved Packet Core (EPC). The com.sec.epdg app provides secure access to communication services like Wi-Fi and LTE.

The com.sec.epdg app conducts a test to check if the ePDG service is working properly on your device. This service is responsible for high throughput, lower call drop rates, higher call transaction rates, better packet data processing for faster data transmission, and more.

What is Evolved Packet Data Gateway (ePDG)?

Evolved Packet Data Gateway (ePDG) is responsible for the integration of multiple core network functions in a single framework. It is a critical part of the 4G core component called Evolved Packet Core (EPC).

Before 4G and LTE were invented, mobile devices primarily used 2G and 3G networks. The 2G and 3G networks used two different sub-domains for switching and processing voice and data.

The 2G and 3G networks used circuit-switched (CS) for voice transmission and packet-switched (PS) for data transmission.

But, 4G and Long Term Evolution(LTE) used ePDG technology that converged voice and data transmission into a single framework called Evolved Packet Core (EPC).

The Evolved Packet Data Gateway (ePDG) works together with Evolved Packet Core (EPC) and untrusted non-3GPP networks to provide security during voice and data transmission via communication services like Wi-Fi, LTE, WiMax, DSL, Ethernet, etc.

4G LTE

ePDG uses IPSec/IKEv2 or IPv6 Protocols to make sure the data and voice transmission is secure over a network. It also makes sure that the transmission has high throughput, requires fewer system resources, maintains Quality of Service, has high system stability, and a lot more.

Is com.sec.epdg a Virus, Malware or Spyware or Is it Safe?

com.sec.epdg is not a virus, malware, or spyware. It is a system application that doesn’t cause any intentional harm to your device and most importantly it doesn’t spy on or sell your data to others.

Some people see this app running in the background and think that it’s bloatware but that is also not true. It doesn’t consume your system resources unnecessarily.

It is a very important application that provides secure access for data and voice transmission over Wi-Fi, LTE, etc., and is present in every Android device that supports 4G, LTE or higher.

com.sec.epdg turned on WiFi

Sometimes, the com.sec.epdg app turns on your Wifi to check network authentication. This app tries to check if data transmission over Wifi can be authenticated when your 4G LTE mobile data network is either not working or unavailable.

If you happen to be in an area where a mobile network is not available then com.sec.epdg can turn on the Wifi to check if data transmission can be done via Wifi by connecting to a nearby Wifi network.

com.sec.epdg has Stopped error

When the com.sec.epdg app crashes, you get an error message “com.sec.epdg has stopped” or com.sec.epdg has stopped working.” These error messages are most common in Samsung devices like the Samsung Galaxy S10, Samsung Galaxy Note 5, Galaxy S7, etc.

These error messages occur due to a corrupted cache or some third-party app that you recently installed on your phone.

If you don’t clear the app cache for a long time, the cache files become corrupted and could lead to app crashes and malfunctions which leads to such error messages.

Sometimes, a recently installed third-party app can cause a lack of memory for the com.sec.epdg app and cause it to crash randomly.

There are also instances where this error message appeared on Android devices that were using a Custom ROM(Firmware) instead of a Stock ROM.

How to fix com.sec.epdg has Stopped error?

I mentioned the reasons why you get this error on Android devices. Now, I will explain how you can fix this error. Follow the methods mentioned below to fix the “com.sec.epdg has stopped” error.

(1) Clear com.sec.epdg App Cache

If the error is due to a corrupted cache then clearing the app cache will fix the problem.

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.

(2) Uninstall Recently Installed Applications from Unstrusted Sources

Sometimes this error message can occur due to an app that you recently installed on your device. You can check if the issue is caused by a system application or a third-party application by booting your device into Safe Mode.

In Safe mode, only pre-installed apps like Settings, Contacts, Messages, etc. can be accessed. You cannot access any third-party apps.

If the com.sec.epdg has stopped” error message stops appearing in Safe Mode then you can be sure that the error was caused by a third-party application.

You can boot your Android device into Safe Mode by following the steps mentioned below.

Step 1 – Turn off your device.

Step 2 – Press and hold the Power button until it vibrates and lights up the screen.

Step 3 – Release the Power button and instantly press and hold the Volume Down button until you see the logo of your device manufacturer.

If you’ve done everything correctly you’ll see “Safe Mode” on the bottom corner of your screen.

Once you have booted into Safe Mode, keep the device running for an hour and check if the error message is appearing. If it isn’t then it’s confirmed that the error was caused by a third-party app.

Now, you will have to check all the apps that you recently installed by going to Settings > Apps.

After figuring out the app that’s causing the issue, you’ll need to Uninstall it and hopefully, the error message will stop appearing.

(3) Factory Reset your Android Smartphone

A Factory Reset erases all the data from your phone and restores your phone to its original state. If you can’t fix the error message using the methods mentioned above then a factory reset will hopefully remove this error message for good.

Before factory resetting your device, you should backup your data in a Cloud service like Google Drive. After the backup is complete, follow the steps below to Factory Reset your Android device.

Step 1 – Go to Settings.

Step 2 – Tap on General.

Flashing the Stock ROM(Firmware) can help you get rid of this error message. It is a complicated process so use it only if the other methods didn’t work for you.

You’ll need to download the Stock Firmware files for your device and you’ll need a flashing tool to flash the stock ROM.

Flashing the Stock ROM will totally fix the issue and the best part is that you can do it yourself using firmware flashing tools. If you’re using a Samsung device then you should use the Samsung Odin flashing tool.

Here is a video that shows how to flash Stock ROM on Samsung smartphones using the Samsung Odin flashing tool.
