I'm using 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 formatted like a date).
- Does anyone knows what it is?
- What does "RF Cal" stands for?
- Where did this terminology come from? What organization/person coined it?
- If "RF Cal" is the manufacturing date of the phone, then why not just call it the manufacturing date of MFD for example? Is it because there is a difference?
