In the past my personal experience with 'tuning' consumer device antennas with AM cb radios, and radio phones VHF & UHF mostly involved trimming the antenna to a precise length, though sometimes this is altered by reflectivity ie near-by objects affect the SWR.
( But those were all external antennas, so much simpler to 'tune' I am sure.)
By the scale, I am pretty certain the smaller antenna as one inside a cell phone case is very sensitive to precise length for transmitting efficiently.
BUT Also, the inter-action with the other components within such a small area, can likely cause different lengths for this inter-action rather than just a calculated length.
After precise adjustment, any movement of the said antenna within the enclosure will cause changes to the antenna performance.
Since this phone is so easily serviced by the 'end user' They should be warned to NOT disturb the internal antenna.
The smaller the antenna the more critical and sensitive the tuning.
