Default Source image is distorted on android release app.

Actual placeholder image size is 100x100 that is below.

<Image
style={{ height: 50, width: 50, borderWidth: 2, borderColor: '#fc6060' }}
source={ { uri: "https://host/static/08_l.jpg" }}
defaultSource={require('./../../assets/image/default_avtar_placeholder.png')}
resizeMode={"contain"} />
Why image is Distorted?
How to resolve this issue?
i know its very late . Recently i also get stuck in this issue , what would i do just wrap Image Component into a View with some style like height and width and defaultSource is working fine according my requirements.
