Trouble navigating with google maps?

Unable to determine your location using GPS?

If you suffer from poor GPS signal, prolonged time for fixing satellites, or GPS plain not working at all, your phone might benefit from this repair.

In this instructable, I will be using the Galaxy S4 as an example. This process should work for all phones, but the disassembly process will differ.

Principles

GPS problems on the mobile phones like the Galaxy S4 is usually due to poor contact between the circuit board and the GPS antenna. This repair aims to provide better electrical contact between the components.

In this instructable, we will use aluminum foil to increase the thickness of the contact and hence the pressure with the phone is pressed together again.

Diagnosis

Firstly, you should determine that the GPS is truly faulty(instead of your navigation app).

1) Try using another navigation app

2) Try updating your apps

3) Download the application "GPS status" to check if your phone is able to detect any satellites and fix onto them

If you confirm that the fault lies in your GPS and not software, you may proceed to gather the following materials:

Materials Needed

1) 2x Small clean pieces of Aluminum foil (1.5cm x 1.0cm)

2) Tweezers (good to have)

3) Clear plastic ruler (for bending small pieces of foil)

4) Small Philips head screwdriver

Lets move on to dis-assembly!
