Matcher.replaceAll () and String.replaceAll () don't seem to work on Galaxy S 6

Question

I need to remove some characters from a string. I'm currently trying to remove '' (space) and '-' (hyphen). I tried two ways. Both of them work on Nexus 5X with Android N Beta. None of them work on Samsung Galaxy S 6 with Android M.

First approach:

String normalizedNumber = phoneNumber.replaceAll("[ -]", "");

Second approach:

Pattern pattern = Pattern.compile("[ -]");
String normalizedNumber = pattern.matcher(phoneNumber).replaceAll("");

How can such base classes give different results? What am I doing wrong?

Proof (screenshots of the debugger taken on different computers, why they differ from each other):

Here is the Nexus

Here is Samsung
