Diagnostics
step by step
What to expect
When is diagnostics needed?
When the phone will not turn on, restarts by itself, overheats, runs slowly, has no signal, does not recognise the SIM card or does not charge; after a drop or contact with liquid; and when it is unclear whether the problem is hardware or software.

How does diagnostics work?
1. You describe the model and the symptoms by phone or through the enquiry form.
2. We clarify whether the device needs to be inspected. Guidance by phone, email or photos is preliminary.
3. During inspection we check what is causing the problem — for example battery and charging, screen and touch, camera and microphone, network connection or software — and explain what has been found.
4. Before paid diagnostics and before any repair, the price or how it is calculated, the parts and the timeframe are agreed. Paid work does not start without your consent.
What should you prepare?
The phone’s make and model and a description of the symptoms — when the problem began, whether there was a drop or liquid, and any earlier repairs. Where possible, back up important data. Do not send passwords, PIN codes or identity documents. More in the terms of service.
Frequently asked
questions
Useful information before your visit
Is diagnostics free?
The price or how it is calculated, and whether it is payable if you decline the repair, is agreed in advance — before paid diagnostics. An enquiry alone creates no fee.
Can I get guidance by phone or from photos?
Yes, but guidance by phone, email or photos is preliminary. An inspection of the device may be necessary.
How long does diagnostics take?
The timeframe is agreed for the specific device and service. Contact us for an estimate.
My phone was in liquid. What should I do?
Switch it off if possible, do not charge it, and contact us as soon as possible. See also: phone after contact with liquid.
