Here is a photo of the sticker on the F-Cable. https://photos.app.goo.gl/bpaNVc0h9U2lyAXA2 * '''Result: ''problem unresolved''''' '''(3) Replace GPS antenna and F-Cable:''' Bought the components from Amazon ($4.90 each) * https://www.amazon.com/gp/product/B00ZK9720M/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 * https://www.amazon.com/gp/product/B01F30BWUI/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Replaced both using the instruction from the following (mostly IFIXIT): * [guide|90317] * https://youtu.be/iqbZRwuvUbs * '''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. * GPS Diagnostic App" https://itunes.apple.com/us/app/gps-diagnostic-satellite-test-tool-coordinates/id1020967894?mt=8 '''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.
