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.

Product Description

✦ For Samsung Galaxy M31 (SM-M315) Antenna Connecting Cable

A worn antenna connecting cable can leave a Samsung Galaxy M31 (M315) struggling to hold a signal, and this listing is the replacement cable for that repair. It is offered as a single part, made for the M31.

Because the cable runs through the inside of the phone, it can be pinched or damaged whenever the M31 is opened. New cable in place, you can check reception properly before the phone is closed again.

Compatibility

  • Samsung Galaxy M31 (SM-M315)

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.

  • Take care not to pinch or kink the cable when routing it and closing the phone.
  • Disconnect the battery before unplugging anything, then test the M31 before sealing it.
  • 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.
