Grunt Build - Angular: app in dist folder does not work - angularjs

Question

I develope an angular app. After building with grunt build, the app in the dist folder does not work on mobile devices (tablet, phone, smart tv) only on PC.
It only loads the background of the page. It is strange, because if I deploy the app folder (so the whole project) it will be loaded..
'use strict';
var lrSnippet = require('grunt-contrib-livereload/lib/utils').livereloadSnippet;
var mountFolder = function (connect, dir) {
return connect.static(require('path').resolve(dir));
};
module.exports = function (grunt) {
// load all grunt tasks
require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);
// configurable paths
var yeomanConfig = {
app: 'app',
dist: 'dist'
};
try {
yeomanConfig.app = require('./bower.json').appPath || yeomanConfig.app;
} catch (e) {
}
