How to convert ionic 4 project to ionic 3

Hello,
I have an issue with ionic 4. My ionic 4 projects (basic projects too, i mean i just run create project code with cli and deployed) not working well on android kitkat, lollipop, marshmallow (4.4, 5 , 6). Ionic 4 project stuck on white screen after splash screen and never work. But its not happen on ionic 3. So i want to transform my main ionic 4 project to ionic 3. Is that possible? Could i use angular 7 and angular material with ionic 3?

   ionic (Ionic CLI)             : 4.6.0 
   Ionic Framework               : @ionic/angular 4.0.0-beta.19
   @angular-devkit/build-angular : 0.10.7
   @angular-devkit/schematics    : 7.0.7
   @angular/cli                  : 7.0.7
   @ionic/angular-toolkit        : 1.2.0

Cordova:

   cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
   Cordova Platforms     : not available
   Cordova Plugins       : not available

System:

   Android SDK Tools : 26.1.1 
   NodeJS            : v8.11.3
   npm               : 5.6.0
   OS                : Windows 7


I am pretty sure the latest version of Ionic v3 is only setup to work on Angular 5.x.x

Easiest way is to just start a new project in ionic 3 and copy the code over. I don’t think it will be possible or It will be a pain to downgrade you app.

I think you should stick on Ionic3 as it is already proved. Even after the official release of v4, lots of bugs are existing.
