Contacts Tag is case insensitive

[nus-se-script]

The current tag for contacts is currently case insensitive and therefore i am able to add two "friend" tags.

However the expectation of tags should function as case sensitive where "FRIEND" and "friend" should add the same tag

Team's Response

• This is the expected behaviour, two tags with different cases are different.
• Being strict about the case sensitivity of tag does not add value to the product. Tags are for users to add 'notes' for a client/delivery, thus there is no need to enforce a specific format.
• In fact, enforcing case sensitivity reduces the flexibility of the product, which makes it a feature flaw.
