I'm using android samsung galaxy s5. When I entered in the dial *#12580*369# it appeared some information about the phone. One of them is RF Cal (it is formated like a date).
- Does anyone knows what it is?
- What does RF Cal stands for?
- Where this terminology came from? What organization / person coined it?
- If RF Cal is the manufacturing date of the phone, then why not just call it manufacturing date of MFD for example? is it because there is a difference?
