@Gr1ver Thank you! This works!

This code works: <TextInput autoFocus={true} onFocus={this.setSel} selection={this.state.select} onChangeText={this.props.changeContent} value={this.props.text}/>

Where this.setSel looks like: _setSel() { this.setState({ select: {start: 1, end: 1} }) }

@nkt You will be able to set selection only after input have receive focus, subscribe to onFocus and onBlur and pass your custom selection depending on focused state.
