Chosen Solution

Hello everyone, several months ago I suddenly had issues with GPS being inaccurate and always giving a several miles radius circle when I am moving, and a much smaller circle when I am stationery. I recently attempted changing the F-shaped antenna cable behind the motherboard. However, When I was inspecting it before removing it I realised that one of the chip connectors (that is attached to the motherboard and allows the F antenna to clip onto the motherboard) was completely detached from the motherboard and stuck to the F antenna. When I tried to remove it, it got lost. I still proceeded with changing the flexi cable and pressed it firmly to the board where there is not chip + taped it. without any surprise, the gps is still the same I would be very thankful for any suggestions or guidance onto how to solve this problem

A boar repair specialist should be able to repair all these issues however it may be cheaper to buy a used iPhone 6 at this point.
