Found a couple issues so far

[MrGurns]

Delete on android doesn't work, It does on iOS
Underlines are drawn on Android, not on iOS (might want to use underlineColorAndroid='transparent')
Styling differences amongst android and ios, Could better utilize the default styling to be justified and aligned instead of offsets.

Furthermore, allowing entry into this for assigning a pin would also be cool.
This would require a change to not auto set the focus, but to handle receiving it, as well as a value field, and very minimum an onChange() field.
Utilizing the same layout as a TextField or other default input types from react native could prove useful.

Hi !

Thanks for your comments !

• "Delete on android doesn't work, It does on iOS" => Should be fixed with react-native 0.53

• for your other remarks, I will take a look in the week, btw, PR is appreciated :)
