What is Com.Android.Defcontainer?

Recently, many Android users have reported unusual activity of the com.android.defcontainer program. And if you are an Android owner, sooner or later you will find this app on your operating software too. But what is com.android.defcontainer, and what does it do? 

It is an additional part or storage option for an installer app. And Android developers pre-install this app on most phones. But we have noticed a report that says it can be faulty sometimes. If you are in the same spot, let us disclose the workarounds. 

What Is Com.Android Defcontainer? 

Indeed, com.android.defcontainer is a package that belongs to the in-built app named Package Access Helper (PAH). This app helps to install and uninstall third-party programs from your phone. 

The com.android.defcontainer package uniquely identifies the PAH installer app. Also, developers include such a package so that it can contain the new update required for the app it belongs to. And it includes the data and code that cannot be stored in the main app due to a shortage of storage. 

Whenever you download or delete an app, this package helps the PAH app to run. As a result, the installation or uninstallation process goes smoothly. 

Why Does The Com.Android.Defcontainer Stop? 

Sometimes, you will receive an error message that says the Access Helper or the com.android.defcontainer has stopped working. This happens mainly when there is a glitch during the installation or deletion of an app. As the package cannot properly delete or download the app, it sends an error notification. 

Also, if you download apps from unauthorized sites, malware can sneak into your software. As a result, the defcontainer package can act up.
