iPhone 8 Plus Microphone Replacement in Astana

Three Microphones and What Each One Does

A One-Minute Self-Test Before You Book

• Voice Memos: record ten seconds and play it back — silence means the bottom unit is out.
• Rear video: shoot a short clip and listen back — no sound points to the rear unit.
• Front video: check the same way — this path uses the upper one.
• Speakerphone call: if the other side hears you only here, the bottom unit is the suspect.
• Siri and voice messages: a microphone that fails these but passes calls is often a software setting.
• Write it down: note which of the four checks failed so the engineer starts from the right part.

What the 8 Plus Shares With Earlier Models

The iPhone 8 Plus keeps the same lower-flex layout as the iPhone 7, but unlike the 6, 6s and 6s Plus it has no 3.5 mm jack and carries IP67 water resistance. The glass back adds wireless charging, and the Lightning port strip now carries the lower microphone together with the charging contacts and the speaker grille. In the 6 and 6s family the headphone socket sat on its own separate assembly, so a failed unit there rarely touched charging. On the 8 Plus, one damaged lower assembly can silence calls and interrupt charging at once. If you are weighing an iPhone 8 Plus microphone replacement in Astana, knowing which flex has failed tells you which part the job needs.

Matching the Symptom to Your iPhone 8 Plus Microphone Replacement Fault

The same complaint can come from three different parts. Below is how we translate what you hear into the specific component that needs work.

From Symptom to the Part We Replace

Cleaning, Dirt and Water Before Any Replacement

Dirt, a case covering the port or a splash of water can mimic a dead microphone, so we clean and dry first and only replace when the part still fails. A thick protective film or a snug case often sits right over the lower mesh, and lint packed into that opening muffles the voice without anything being broken inside. The iPhone 7, 8 and 8 Plus carry an IP67 rating, which resists a quick splash but does not stop moisture from reaching the ribbon over time. After water contact, diagnostics can take up to two days, because oxidation on the strip may only show once the board is dry and retested.

When a Clean Is Not Enough

If the voice is still muffled after the mesh is cleaned and the port is dried, the microphone element itself has failed and the ribbon has to be swapped. We put the cleaned port under the microscope and show you the result before quoting a part, so the difference between surface dirt and a corroded contact is visible rather than assumed. A membrane that looks intact can still have oxidation on the pads beneath it, and that is where a muffled call turns into a replacement job. Ask to see the port through the eyepiece — it takes a minute and settles whether cleaning was ever going to be enough.

Why a Microphone Job Often Means a Charging Flex

Owners often arrive expecting a small microphone fix and leave with a ribbon replacement instead. The two are the same component on this model, and understanding why saves confusion and a second visit.

One Flex, Several Functions

On the iPhone 8 Plus the lower microphone is soldered to the charging assembly, so a failed unit is replaced together with the Lightning port and its strip. The assembly runs along the frame edge and carries the mic, the connector itself and the contact pads that link the board to the port. Because the microphone sits on that strip rather than on a separate lead, a dead unit and a worn socket are handled in one operation. The upper microphone near the earpiece is a separate part, which is why top and bottom faults behave differently. That is why such a repair can also restore power intake or fix a loose connector — the same strip carries all three, and one replacement covers them.

What Else the Lower Flex Carries

• Power intake: plug in a cord and confirm the battery icon responds.
• Data transfer: connect to a computer and check the device is recognised.
• Antenna contact: confirm signal bars return after reassembly.
• Microphone: record a voice memo and play it back on the spot.
• Packaging: we show the new part in its factory bag before fitting.

When the Problem Is the Board and Not the Microphone

Sometimes the microphone is intact and the sound still disappears. Here is how to tell a hardware fault and a software glitch apart from a genuinely dead part.

Software Settings That Mimic a Dead Microphone

• Bluetooth: disconnect headsets and speakers, then retest a call — a paired device can quietly capture your voice instead of the built-in mic.
• Permissions: open Settings and confirm each calling and recording app still has microphone access after the latest update.
• Noise cancelling: toggle the setting off and on to reset it, since a stuck profile can mute the input.
• Restart: a full reboot clears frozen processes, and it costs nothing before you book anything.

Board-Level Faults and the Grey Speaker Button

A greyed-out speaker button, a dead Voice Memos app and slow booting together point to the codec chip on the logic board, not to the microphone. When that component fails, the phone loses input and output at once: the speaker icon stays grey during calls, recordings come back silent, and the device takes noticeably longer to reach the home screen after a restart. The same circuit sits inside the iPhone 7, so the symptom reads identically across both generations. We confirm the fault during free diagnostics, then repair the board under a microscope — that job runs one to three days, unlike a 20–40 minute strip swap. Confirming the codec first is worth it before you agree to a bottom ribbon replacement that cannot help, and our engineers show you the test result on the spot so the decision rests on evidence rather than guesswork.

How the Replacement Runs and What You Get Back

From the first photo to the moment you walk out with the phone in your pocket, the job follows a fixed sequence — and each step leaves you with something in hand, not just a promise.

From WhatsApp Photo to Pickup

• Photo on WhatsApp: an engineer replies within five minutes and quotes a price from the picture.
• Free diagnostics: 15 minutes in front of you, and it stays free even if you decline the repair.
• Receipt: price, part, turnaround and warranty are fixed on paper before work starts.
• Waiting area: coffee and Wi-Fi while the lower ribbon is swapped out.
• Courier: a courier can be called if you cannot come in yourself.

The Check Before You Leave

Before you leave we run 32 functions in about ten minutes, microphones included, and hand back the receipt, the warranty card and the old part. The replacement itself arrives in factory packaging and is shown to you before installation, so you see the component that goes into the phone rather than a loose part on a tray. Coverage runs up to 1 year, and the removed ribbon goes home with you as proof the swap actually happened. We suggest hearing the voice memo and the video playback together with the engineer — a microphone that passes a call can still fail in video, and catching it on the spot saves a second trip across the city.
