Frequently Asked Questions

What does the antenna sub board do?

It carries signal and connects key components at the base of the phone. Faults can show as poor signal, charging quirks or connection dropouts.

What part is fitted in the Xperia 1 VII antenna sub-board repair?

Every Xperia 1 VII antenna sub-board repair uses a genuine Sony antenna sub-board made for this model, fitted at our Liverpool Street workshop. Mobile signal, calls and data are tested before return.

Why not just replace the port or battery?

We diagnose first, because sub board faults can mimic other issues. We confirm the cause before repairing.

Is my data safe?

Yes, it is a hardware repair.

How long does it take and what warranty applies?

Confirmed at diagnosis, with a 12-month warranty on the repair.

Walk-in or mail-in?

Both, near Liverpool Street Station or by UK post.
