I am listing this solution first because users has less attention to this, yet it is the simplest and most effective one. App Disabling – there are a lot of user who have found deleting an app which may have being causing the MMI code error. However, this may not be the case for most people. To find out if there is any app that may have be causing you to get this error, you simple need to go into safe mode on your phone.In this guide we will be using Samsung Galaxy.
What is Safe Mode?
Safe mode is very similar to a computer’s safe mode. It do not load any Apps. Basically it temporarily disabled all pre -installed applications and services that came with the phone and the one’s you have downloaded

To enter safe mode and to find out if there’s a culprit app that may be interfering with network operation of your phone, kindly follow the instruction below . Apps Like FX Camera is seen to be a treat in most cases.However, to enter safe mode:
>Turn OF your phone
>Hold the Power button
>While holding the power button keep tapping on the menu button, this is the button left of the home key
You will be greeted with a safe mode logo at the bottom left of the screen.
Now it’s time to test .
>Enter the same Prefix code you were trying before within the dialer and see if it works eg “*135#
>If it works then there is an app is causing the Invalid MMI Code error on the android phone .
>Reboot your phone and remove any recently installed apps
Another simple and effective way to fix Connection Problem or Invalid MMI Code on android phone is to add a comma at the end of the Prefix code.
>If your Prefix code is *2904*7#

You can use the + symbol after *
