Phone diagnostics
Phone diagnostics — not sure what's wrong?
Phone acting up and you can't work out why? You don't need to know the exact fault to get in touch. We come to you, take a proper look, tell you what's going on and explain your options — before anything goes ahead.
Common faults we diagnose
Tell us what the phone is doing. These are the situations we're asked about most, and what we look at first:
Won't turn on
No logo, no vibration, no charging icon. We check whether it's the battery, the charging path or the screen simply not showing a picture — a phone with a broken display can still be running.
Stuck on the logo or restarting
A boot loop can follow a failed update, a worn battery that can't supply enough power, or hardware damage after a drop. We work out which before recommending anything.
No signal or "No SIM"
We rule out the SIM, network and settings first. If those are fine, the fault may be inside the phone — and we'll tell you honestly if it's not something we can repair.
Overheating
Heat while charging, during light use or in a pocket can point to a worn or swelling battery, a charging fault or a software process. A swollen battery is a safety issue — stop charging it and tell us.
Touch or display faults
Ghost touches, dead areas, flicker or lines. We check whether it's the screen or something else, so the repair you agree to is the one that actually fixes it.
Charging problems
Slow, intermittent or no charging. We test with a known-good cable and charger and inspect the port before suggesting a port repair or battery.
What a diagnosis involves
We ask what happened and when it started, check the phone with you, and test the suspected parts. Then we explain the likely cause in plain English, what the repair would involve and the price — and you decide. If something can't be repaired sensibly, we'll say so rather than sell you a part that won't help.
Before the visit, back up the phone if you can, and tell us the exact model and anything that has already been tried, such as a different charger or a restart.
How it works
You don't visit a shop. We agree a time, come to your home or workplace, and carry out the repair outside where possible. We always explain what's involved and agree it with you before starting.
Parts & repair information
The exact part options, availability and details for your repair are discussed and agreed with you before any work begins. Read more
