leading 0 gets cutoff in phone number

Steps to reproduce:
Select South Korea as country, enter 01035353535 as the phone number.
getFormattedFullNumber(), getFullNumber() and getFullNumberWithPlus() returns the phone number with leading 0 cutoff. 820035353535

Attached is the screenshot from the sample app:

Search the Java codebase for getFormattedFullNumber(), getFullNumber(), and getFullNumberWithPlus(), then reproduce the South Korea example in the sample app. Trace how 01035353535 is converted and verify that all three methods preserve the leading 0 and return the expected full number.
