== '''My take on the GPS problem for iPhone 6:''' ==
'''GPS problem encountered (only when using LTE or 4G):'''
* The google map could not place me accurately.
* My location kept jumping around with in a radius > 1 km
* Location was accurate only when connected to WIFI
== '''After countless hours of research, I decided to try one solution after another with the increase in complexity:''' ==
'''(1) Tried soft troubleshooting as described on this link: '''

* '''''Result: ''problem unresolved'''''''
'''(2) F-Cable sticker:'''
Repositioned it several times. Here is a photo of the sticker on the F-Cable.

'''(3) Replace GPS antenna and F-Cable:'''
Bought the components from Amazon ($4.90 each)

Replaced both using the instruction from the following (mostly IFIXIT):

* '''Result: ''SOLVED!!!'''''
'''GPS signal evaluation:'''
* Downloaded the app GPS Diagnostics from app store ($2.99). You can use any other apps if you want.
* The App confirmed the GPS signal strength to above 80% and with an accuracy of +/- 10 meter.
* It was a significant improvement from the accuracy being +/-1440 meter before the antenna and cable replacement.

'''Comments:'''
* Apple said that it would cost $299 to repair or to get a new phone.
* Fixed the problem by spending $9.80.
* Not sure if it was the F-cable or the GPS antenna that was malfunctioning but am happy that I got it fixed.
