Hi to all,
I write this, because of my own expirience. There is a misunderstanding, how to install.
How to install it the right way you can see here: https://www.youtube.com/watch?v=l8JbDGoSvjA
Unfortuanally it`s german, but watch it exactly and you are able to use the dialer.
Other way is to read my guide:
---NO ROOT NEEDED!!!!
---MCTDialer 1.2.2 works with usual px3 and px5 HU ( xtron, erisin, witson, and so on) and Android 6 or higher.
---Google assistant ("OK Google") has been installed CORRECTLY. Best way including it is working offline too.
---Download the MTCDialer apk to your HU, refer Post #1 or use the links coming with the linked clip above.
---when you have google assistant on your phone too: make sure it is not able to react parallel.
(Normally if your phone is turned on but not activated (screen is dark), otherwise disable activation by saying "OK
Google" or your voice) at first.
---when you use a contact app on your HU then disable it... There is no need for, when you initiate mtcdialer the way described below. (You can delete it after succeed testing the installation guide)
Installation (true step by step):
--- connect your phone with your HU via bluetooth.
---make sure the embaded HU BT is really paired with your phone.
---install the MTCDialer apk. (after direct download you will find it in the internal storage/download folder) on the int. storage
When installation is ready don't open the mtcdialer, just click finish. (click even means push on it with your finger)
---Open the Google BrowserApp himself (do not open the google assistent or Chrome or Firefox or something else)
---use the searchbar and WRITE: call 03000 ( you can use your natural language, if you install it with google assistant) and press enter or go or ready
---click on the first blue colored phone icon (under the searchbar)
---Now there are presented some icons. You choose the mtcdialer by click it (remember: with your finger)
---At next click on the second phone icon* to start the call *( mostly a blue circle with a white phone)
---When the phone bar appears click on the red button. mtcdialer now is stored as default using app. (IMPORTANT)
---Say "OK Google call mom in law" (When you saved her as dragon then say "OK Google call dragon", cos google don't know about the nickname you gave. When you stored dragon with more than one number, the assistant will request which one is to use)
---It should function now. So be happy and face your next problem, e.g. with the dragon sitting beside you during this procedure
I hope this guide helps you. I read it to my rave and he was succesfull using it.
So I'm sure you will succeed too.
