Overview
What this part is
The Galaxy S6 Edge uses a thin antenna flex to carry WiFi signal inside the phone. If it is torn during a repair, or corroded by liquid, WiFi can become weak, drop out or only work close to the router.
This flex is made for the Galaxy S6 Edge SM-G925F. Before ordering, restart the phone and reset network settings, as software problems can look like a hardware fault.

How to check your model

Test another device on the same WiFi. If it works well there, the phone is the likely fault.
Professional installation
How a technician fits this part
- Power off the phone and warm the back glass to soften the adhesive.
- Lift the back glass carefully and disconnect the battery.
- Remove the covers above the main board to reach the antenna flex.
- Unclip the old flex and fit the new one, pressing each connector home.
- Reconnect the battery and test WiFi range before sealing.
- Refit the covers and back glass with new adhesive.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my Galaxy S6 Edge?
Yes, if Settings › About device shows Galaxy S6 edge with model number SM-G925F.
Does it fit the Galaxy S6 Edge+?
No. The larger S6 Edge+ has a different internal layout.
Will it improve mobile signal too?
No. This flex carries WiFi signal. Mobile network signal uses separate antennas.
Is it made by Samsung?
No. It is a brand new, OEM-quality WiFi antenna flex cable made to fit the Galaxy S6 Edge, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The glass back must be heated and lifted, and the small antenna connectors are delicate.
How quickly will it arrive?
