Simple example to reproduce:

<html>
	<body>
	    <p>Image file:</p>
		<input id="fileInput" type="file" />
		<div onclick="uploadFile()"><b>Upload</b></div>
		<p>Image:</p>
		<img />
		<script>
			function uploadFile() {
				var file = document.getElementById('fileInput').files[0];
				var fr   = new FileReader();

            fr.onload = function (args) {                
                var raw = window.atob(fr.result.replace('data:image/png;base64,', ''));
                var rawLength = raw.length;
                var uInt8Array = new Uint8Array(rawLength);
                for (var i = 0; i < rawLength; ++i) {
                    uInt8Array[i] = raw.charCodeAt(i);
                }
                var content = new Blob([uInt8Array]);
                //Now content contains data processed as script.
                // But if uInt8Array is a binary data (jpeg, png, etc) then we should not process it
            };
            fr.readAsDataURL(file);
        }
		</script>
	</body>
</html>

The problem blocks image upload testing in mobile XAF.
