How to solve simple questions about an Ionic application?

Question

Angular

Newbie in this business, I think it will not be difficult to answer a couple of questions for professionals.
1) How to turn off the initial splash screen in the application? I tried to change the values ​​​​in config.xml, but during subsequent compilation the values ​​\u200b\u200bare returned to the default ones.
2) How to revive the "Call" button? I try this: I added a line to AndroidManifest.xml

<uses-permission android:name="android.permission.CALL_PHONE" />

, in the template I use

<a class="button button-block icon-left ion-ios7-telephone button-positive" ng-href="tel: [phone]">Позвонить</a>

, through the browser tries to call, from the application - is silent.
Thank you.
