@ruggb - that is the weird part. They do not connect to anything (contact connections) They touch the plastic bracket, that does not have any metal points. It is like it was made for some extra.

the UFL SMT Antenne is down in the right corner for 2 antennas

It got me curious, because they do not connect to anything, the ones I marked

it is possible it is a common board used in other phones. Many mfg do that. sometime with parts populated for different features.

the green on appears like contact connections maybe for a speaker. The red ones look like uFL SMT Antenna Connectors. But I have no idea why there are 6 of them.
