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.
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.
