Typical Signs of Microphone Malfunction

 

• Poor sound during conversation — hissing, silence, voice lag.
• I can't be heard during calls in Prague, even though other functions work.
• Problem with voice recorder or voice messages — sound records with interference.
• No sound in video — microphone doesn't work in apps.
• Presence of ambient noise sound, but absence of your voice — a common symptom of a faulty MEMS microphone.

 

What Do We Offer?

1. Fast repair of iPhone and Android microphones in Prague. We work with all popular brands — Apple, Samsung, Xiaomi, Huawei, Realme, Oppo, Sony, etc. For iPhones, we use only original microphones or high-copy A+ grade (if original is not available).

We have everything needed for fine board assembly, especially in cases where the microphone is integrated on a flex cable or in a system module. In many modern models — for example, iPhone 12, Samsung Galaxy S22, or Xiaomi Mi 11 — microphones are often installed as part of several modules: call, noise cancellation, video recording. Incorrect operation of one of them can affect sound quality in all applications. We carefully check each channel.

2. Phone microphone cleaning. Often the problem is not a breakdown, but clogging of the microphone hole with dust, skin oil, or moisture. In such cases, replacement is not needed — we perform careful ultrasonic cleaning of the microphone mesh or housing without damaging the components.

For devices that have been in water, a complete cleaning of the board in isopropyl alcohol in an ultrasonic bath is provided, followed by a sound check in several modes — voice call, recording, video, speakerphone.

3. Service diagnostics. At Technofix, primary diagnostics are free. We will accurately determine whether the microphone, flex cable needs replacement, or if the problem is with the board or audio codec (e.g., Cirrus Logic, Skyworks, or Qualcomm WCD9340 in iPhone 13 Pro).

In complex cases, our engineers use microscopic analysis and software diagnostic platforms, allowing them to find problems even at the level of missing power on the audio line or failures in the I2S bus.

4. Replacement or restoration. After diagnostics, we agree on the cost and terms with the client. If the microphone is removed from the board, it is re-soldered on a BGA station to avoid damaging the contact pads.

For budget models, verified spare parts from Luxshare, AAC Technologies, or Goertek are used.

  Can I clean the microphone myself? You can, but it's dangerous: using a needle, toothpick, or alcohol can permanently damage the capsule. It's better to entrust this to a master. Microphone doesn't work after iOS update — what to do? Failures at the firmware or controller level are possible. We reflash the system, reset settings, or replace the audio controller if needed.
