How to Change the MMS.APK in an Android

The MMS.apk file on your Android smartphone corresponds to the multimedia messaging application that you use to send MMS picture and video messages. In some instances, updated system applications are leaked from newer operating system updates before the OS updates are public, and hobbyists like to install the updated apps on their Android phones. If you have an updated or edited MMS.apk file that you wish to install over the existing app you use to send MMS messages, you can do so by following a few steps.

Instructions

1. • 1
     Tap the "menu" button on your Android phone, and then tap the "Settings" option.
   • 2
     Tap the "Applications" option.
   • 3
     Enable the check mark next to "Unknown sources" by tapping on it. This allows you to install applications from sources outside of the Android Market, and is necessary to complete the process.
   • 4
     Open the MMS.apk application, either from a website, from an email message (if it was sent to you as an attachment) or from the storage on your phone (if you transferred it there yourself).
   • 5
     Tap the "Yes" button when the dialog box that asks, "MMS.apk already exists. Would you like to overwrite it?" appears.
   • 6
     Restart your Android smartphone after the installation.
