Fitting advice

Phone parts are delicate. We recommend fitting by a qualified repair technician.

Test the part before final installation, before any adhesive or seal is applied. Parts with adhesive applied can’t be returned for change of mind.

You have 30 days from the day you receive your item to request a return. Items must be unused, in the condition and packaging they were supplied in, with proof of purchase.

Please contact us before sending anything back. Return postage is the buyer’s responsibility unless the item is faulty. For faulty or incorrectly described items, we cover return postage in full. Approved refunds go to the payment method you used within 10 business days. Your statutory rights are not affected.

Product Description

✦ For Samsung Galaxy A12 (SM-A125F) Antenna Connecting Cable

Here is a replacement antenna connecting cable for the Samsung Galaxy A12 (A125F). It is the shielded lead that links the phone's signal path, and a damaged or loose one can leave the A12 with weak signal, dropped calls or a failing connection. Replacing it is a repair for those faults, not a cure-all.

Working on the A12 means opening the phone, lifting the old cable clear and pressing the new one onto its connectors.

Compatibility

  • Samsung Galaxy A12 (SM-A125F)

Signs Your Flex Cable Needs Replacing

  • A function linked to the flex (such as display signal, charging, buttons, signal or sensors) stops working or cuts in and out.
  • The fault appears after a drop, liquid exposure or a previous repair.
  • The flex is visibly torn, creased or has a damaged connector.
  • The problem changes when the phone is pressed or flexed.
  • Before replacing, reseat the connectors — a loose connector can cause the same symptoms.

How to Check Your Model Number

On the phone or tablet go to Settings › About phone (or About tablet). The model number starts with SM- (for example SM-A145R). It is also printed on the box the phone came in.

⚠️ Important — Please Read Before Purchase
  • This listing is for the antenna connecting cable only, not a full phone or a circuit board.
  • The phone must be opened to fit this part, which takes heat and careful prying.
  • Lift the connectors with a plastic tool rather than pulling on the cable, as coaxial leads are easily damaged.
  • Test signal, calls and Wi-Fi before the phone is sealed.
  • Replacement parts are model-specific — check that your device matches the model shown above before ordering.
  • Professional fitting is recommended where the device has to be opened; flex cables and connectors are easily damaged.
  • Test the part before sealing the device or applying new adhesive.
  • If you are unsure which part you need, contact us with your model number before ordering.
Your statutory rights under the Consumer Rights Act 2015 remain unaffected for faulty or not-as-described items.

Frequently Asked Questions

What does the A12 antenna connecting cable do?

On the Samsung Galaxy A12, the antenna connecting cable carries signal between the boards inside the phone and the antenna. If it is damaged or has come loose, the A12 can lose reception.

Should I replace this cable if my A12 has no signal?

It is worth checking if your A12 has weak signal or no service after a drop or an earlier repair, and the cable looks damaged, kinked or unclipped. Other faults can cause the same symptoms, so inspect the A12 first.

Is this antenna connecting cable made for the Samsung Galaxy A12?

Yes, it is listed for the Samsung Galaxy A12 (model A125F). Check the model number of your A12 before ordering, as similar-looking Galaxy phones use different cables.

Do I need to open my A12 to fit it?

Yes. The A12 has to be heated and pried open, the old cable lifted off its connectors and the new one pressed on. If you are unsure, use a repair professional.

What should I check after fitting it to the A12?

Before you seal the A12, switch it on and confirm you get signal, can make a call and connect to Wi-Fi. Then close the phone.
