Device Testing That Gets to the Real Problem
Some faults are easy to identify. Others can have several possible causes. A device that will not charge, for example, could have a damaged charging port, faulty battery or another internal issue.
Our diagnostic service helps narrow down the cause before you commit to a repair.
Battery & Charging Diagnostics
If your device is losing charge quickly, refusing to charge or switching off unexpectedly, we can investigate the battery and charging system.
Screen & Display Diagnostics
We assess display problems such as flickering, lines, touch issues, black screens and other screen faults.
Software Diagnostics
Problems such as crashes, freezing, slow performance and unexpected restarts can sometimes be software-related. We check for common causes before recommending a repair.

Device Diagnostic FAQs
What is a device diagnostic?
A device diagnostic is a series of checks used to identify why a phone, tablet, laptop or other electronic device is not working correctly.
How long does a diagnostic take?
The time required depends on the device and the fault. Straightforward problems can often be assessed quickly, while intermittent or complex faults may require additional testing.
Do I have to repair my device after the diagnostic?
No. A diagnostic gives you information about the problem. You can then decide whether you want to proceed with the recommended repair.
Can you diagnose a device that will not turn on?
Yes, depending on the fault. We can investigate power, charging, battery and relevant hardware components to determine what may be preventing the device from starting.
Can you diagnose slow or freezing devices?
Yes. Slow performance, freezing, unexpected shutdowns and repeated crashes can have several causes, so we assess both hardware and software where appropriate.
Do you diagnose water-damaged devices?
We can assess supported water-damaged devices and check for visible and underlying signs of liquid-related damage.
