MicroPhone IC for Samsung I9500 Galaxy S4

The Microphone IC in your Samsung is the preamplifier chip that receives the raw electrical signal from the microphone capsule and amplifies it to a usable level before passing it to the main Audio IC for further processing. Without a functioning Microphone IC, the audio signal from your microphone capsule is too weak or distorted to be processed correctly — causing the other person on a call to hear nothing or a very faint, distorted voice from your Samsung .

If the microphone capsule is confirmed undamaged and correctly connected but microphone input is still absent, very weak, or severely distorted — and if this persists across all apps including the voice recorder — the Microphone IC is the likely board-level cause on your Samsung . A board-level technician can confirm by measuring the output signal of the microphone capsule directly.

Yes. The Microphone IC processes all microphone input on your Samsung — whether for phone calls, voice messages, video recording, or voice commands. A failed Microphone IC will cause silent or distorted audio across all recording and communication functions that use the affected microphone.

No. The Microphone IC is a micro-SMD chip soldered onto the Samsung motherboard. Replacement requires hot air rework equipment, flux, and professional board-level repair skills. Attempting this without proper tools will permanently damage the motherboard.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once the chip has been soldered it is considered used and cannot be returned. For more information, check out SAHII's Return Policy.
