Button, SIM, Wi-Fi and NFC Repair in Düsseldorf
A phone is made up of more than a screen and a battery. If a button sticks, the Wi-Fi keeps dropping or Apple Pay stops responding at the till, we repair exactly that part, and you do not have to replace the whole device.

For most repairs
Which part has stopped working?
Buttons: power, volume, Home and Action button
A button sticks, only works when you press very hard or does not respond at all. Usually the small flex cable under the button is torn or dirty. We replace the cable or the button, and everything else on the device stays untouched.
SIM tray and SIM reader
The phone says “No SIM” even though the card works in another device. Then the contacts in the reader are often bent, or the tray is stuck after a fall. We straighten or replace the reader.
Wi-Fi and Bluetooth
The Wi-Fi keeps dropping, no longer finds any networks, or the switch in Settings is greyed out and cannot be tapped. Bluetooth no longer finds your headphones or your car. The cause is either an antenna or its cable, or a component on the logic board. We find out which during the diagnosis.
NFC for Apple Pay and Google Pay
Contactless payment no longer works, the terminal does not beep, or the phone does not recognise NFC cards. If the case and the wallet are fine, the fault is usually in the NFC antenna. On many iPhone models it is connected to the charging coil at the back, which is why both often fail at the same time after the back glass breaks.
Reception and signal
The phone has no reception where other phones show full bars, or it keeps searching for a network. Often an antenna cable has come loose after a fall. We check the antennas and their connections before we go to the logic board.
Wireless charging and MagSafe
Nothing happens on the charging pad any more, but the phone charges with a cable. Then the charging coil at the back is affected, often after a fall onto the back. We replace the coil, on the iPhone together with the NFC antenna if both sit on one part.
Vibration motor
The phone no longer vibrates, or it hums and rattles loudly when it does. The motor is a separate component and can be replaced on its own.
Face ID and Touch ID
Face ID is not available or your fingerprint is no longer recognised. Both sensors are firmly paired to the logic board of your device, so a third-party spare part cannot take over this job. We check whether the problem is the sensor itself or its cable, and then tell you what is possible.
Proximity sensor and ambient light sensor
During calls the screen stays on and you hang up with your ear, or it switches off even though nobody is calling. This is often down to the proximity sensor, and after a screen replacement it can also be a sensor that was fitted incorrectly. We check both.
Headphone jack
On devices that still have a headphone jack, the sound cuts in and out or the plug is not recognised. Usually the jack is dirty or worn out, and we clean or replace it.
What you can try yourself
With many of these faults a restart helps, or a look at your accessories. A case with a magnet or a card in it interferes with NFC and wireless charging. A forgotten Bluetooth connection to your car makes the phone seem silent. And a screen protector that covers the sensor at the top of the screen confuses the proximity sensor.
If none of that helps, reset the network settings in Settings. Your photos and apps are kept, and you only have to enter saved Wi-Fi passwords again. If the fault is still there afterwards, it is a job for us.
Questions about the small repairs
Apple Pay no longer works. Is that a hardware fault?
Not always. First take off the case, especially if there is a card or a magnet in it, and check in the wallet whether your card is still active. If it still does not work after that, and the phone does not recognise other NFC cards either, the NFC antenna is usually affected. We look at it for free.
The Wi-Fi switch on my iPhone is greyed out. Can that be repaired?
Yes. A greyed-out switch means that the iPhone can no longer find the Wi-Fi chip. That is a case for the logic board, and we repair it in-house. You can find more about this under logic board repair.
Can I have just a single button repaired?
Yes, of course. A button or a vibration motor is one of the smaller repairs, and afterwards you have a phone that works in every respect again. We tell you the price after the free diagnosis.
How long do these small repairs take?
Most repairs take 20 to 60 minutes. We tell you how long it will take for your device after the diagnosis.
