Mobile Phone Speaker Repair Dundee

Phone calls sound muffled? Can’t hear the person on the other end? Loudspeaker crackling when you play music? Or maybe folk on the other end can’t hear you at all?

Speaker and microphone problems are more common than you’d think. Sometimes it’s as simple as debris packed into the speaker grille. Sometimes the speaker module or microphone has failed and needs replacing.

Before you assume the worst, bring it in and let us take a look. We see a lot of phones come in for “speaker repair” where the fix is just cleaning out the speaker grilles. Pocket lint, dust, and general muck builds up over time and blocks the sound. If that’s all it is, it’s a quick and cheap fix.

If the speaker or microphone module itself has failed, we replace it. Most phones have two speakers: the earpiece speaker at the top (the one you hold to your ear during calls) and the loudspeaker at the bottom (for speakerphone, music, videos, and ringtones). They’re separate modules and can be replaced independently.

At Repair Alliance on Perth Road, we repair speakers and microphones on iPhones, Samsung, Google Pixel, Huawei, OnePlus and more. We test call audio, media playback, speakerphone, and microphone quality after every repair.

Most speaker repairs are done same day. Your data stays completely untouched. Walk-ins welcome, nae appointment needed. Every repair comes with a 90-day warranty.

Common Phone Speaker Problems

Here are the speaker and microphone faults we see most:

Earpiece speaker quiet or muffled during calls. You can barely hear the person on the other end, even with the volume turned all the way up. Could be a blocked speaker grille (lint and debris) or a failing earpiece speaker module. On iPhones, the earpiece also handles part of the stereo sound during media playback, so you might notice one side of the audio is quieter than the other.

Loudspeaker not working. No sound from the bottom speaker. No ringtone, no media audio, speakerphone doesn’t work. Could be a failed loudspeaker module or a loose flex cable connection.

Crackling or distorted sound. The speaker works but the sound is distorted, especially at higher volumes. Usually a speaker module that’s partially failed or has been damaged by water. The speaker membrane can tear from playing audio at maximum volume over time, or from a drop that knocked the voice coil out of alignment. Even a small amount of moisture can affect speaker performance.

Microphone not working. Folk on the other end can’t hear you during calls. Or voice messages and videos have no audio. The microphone module is often on the same flex cable as the charging port, so a microphone repair sometimes involves replacing the charging port assembly.

No sound at all. No speaker audio, no earpiece audio, nothing. Could be a software issue (check the volume and Do Not Disturb settings first) or a hardware fault. We diagnose which.

Sound only works on speakerphone. Call audio works through the loudspeaker but not through the earpiece when you hold it to your ear. The earpiece speaker has failed but the loudspeaker is fine. Common issue.

Muffled sound after water exposure. Water gets into the speaker grilles and affects the membrane. Sometimes it dries out and comes back. Sometimes the speaker needs replacing if the water has damaged the voice coil.

Bluetooth audio works but phone speaker doesn’t. Audio plays fine through Bluetooth headphones or a Bluetooth speaker, but the phone’s built-in speakers don’t work. Confirms it’s a hardware issue with the phone’s speaker, not a software problem.

Is It Actually Broken?

Before paying for a speaker repair, check these things first. We see folk come in convinced their speaker has died when the problem is something much simpler.

Check your volume and silent mode. Sounds obvious, but the side switch on iPhones gets flipped accidentally in pockets and bags. On Android, the volume rocker has separate levels for ringtone, media, and call audio. Make sure all three are turned up.

Turn off Bluetooth. If your phone was previously connected to a car, headphones, or a Bluetooth speaker, it might still be routing audio to that device even though you’ve walked away from it. Turn Bluetooth off completely and test again.

Check Do Not Disturb. DND can silence ringtones and notifications without you realising it’s on. On iPhone, check Settings > Focus > Do Not Disturb. On Android, swipe down and look for the DND icon.

Restart your phone. Software glitches can block audio output. A restart clears the audio routing and resets connections. This genuinely fixes the problem more often than you’d expect. Apple has a troubleshooting guide for iPhone speaker issues that covers the basics. Google Pixel phones had a known speakerphone bug that was fixed with a software update in late 2025, and Android 14 had audio routing issues with Bluetooth and casting devices.

Clean the speaker grille. Use a soft-bristled toothbrush or a dry cotton bud to gently brush across the speaker openings. Don’t use anything metal or sharp. Don’t poke into the grille. You’re trying to dislodge lint and dust, not push it further in. If the sound improves, that was the problem.

Test with a voice recording. Open the voice recorder app, say something, and play it back. If the recording sounds fine through the loudspeaker, the loudspeaker works. If the recording captured your voice clearly, the microphone works. This isolates which component is actually faulty.

If none of these help, it’s a hardware problem and it needs hands-on diagnosis. Drap it in and we’ll check it properly.

Earpiece vs Loudspeaker

Your phone has two main speakers and they do different jobs:

Earpiece speaker (top). This is the small speaker at the top of the phone that you hold against your ear during calls. It also handles part of the stereo audio during media playback on newer phones. When this fails, calls sound quiet, muffled, or silent when you hold the phone to your ear. Speakerphone might still work fine because that uses the loudspeaker at the bottom. The earpiece is a precision component with a very small membrane designed for close-range audio at controlled volumes.

Loudspeaker (bottom). This is the main speaker that handles ringtones, alarms, media playback, speakerphone calls, and notification sounds. It’s louder and more powerful than the earpiece, with a larger membrane designed to fill a room with sound. When this fails, you lose all audio except for call audio through the earpiece (when held to your ear). This is the speaker that takes the most abuse because folk play music and videos at full volume.

If both speakers fail at the same time, it’s more likely to be a software issue or a logic board problem than both speaker modules failing simultaneously. We diagnose which scenario applies before recommending a repair.

Knowing which speaker is affected helps us quote you accurately. Earpiece and loudspeaker replacements are different parts at different price points. Tell us which one isn’t working (or both) and we’ll give you the right quote.

How We Diagnose Speaker Faults

When you walk in with a speaker problem, we run through a set of tests to identify exactly what’s wrong before touching any tools.

Software check. We verify it’s not a software routing issue. Volume levels, Bluetooth connections, Do Not Disturb, audio output settings. If a restart or settings change fixes it, you’re sorted without any hardware work.

Earpiece test. We make a test call through the earpiece speaker and listen for clarity, volume, and distortion. We test at low, medium, and high volume because some speaker faults only show up at certain levels. A speaker that sounds fine at low volume but crackles at high volume has a partially torn membrane.

Loudspeaker test. We play media audio through the bottom speaker and test ringtone playback, speakerphone, and notification sounds. We check both left and right channels on phones with stereo speakers to see if one side has dropped out.

Microphone test. We record audio and play it back to check microphone pickup. Modern phones have multiple microphones (bottom, rear, top) and we test each one. A failing bottom microphone affects calls; a failing top microphone affects noise cancellation and speakerphone clarity.

Physical inspection. We check the speaker grilles for debris, corrosion, or physical damage. We look for signs of water exposure around the speaker openings. On phones that have been dropped, we check whether the speaker module has been dislodged from its housing.

Once we know exactly what’s wrong, we give you a clear quote. If it’s just a clean, the cost is minimal. If a module needs replacing, we tell you which one and what it costs before we start.

How We Repair Phone Speakers

If the speaker grilles are blocked, we carefully clean them out with the right tools. A proper clean with anti-static brushes and controlled compressed air at low pressure does a better job than anything you can do at home without risking damage to the mesh. If that fixes it, the cost is much less than a full speaker replacement.

If the speaker module itself needs replacing, we open the phone and swap it out. The earpiece speaker sits at the top of the phone near the front camera. The loudspeaker sits at the bottom near the charging port. They’re separate components and we replace only what’s needed.

For microphone issues, the microphone is usually on the same flex cable as the charging port. So a microphone replacement often means replacing the charging port assembly as well. This sounds more involved than it is. We do it regularly and it’s a straightforward repair.

After fitting the new speaker or microphone, we test everything. Call audio at different volumes, media playback through the loudspeaker, speakerphone clarity, and microphone pickup. We make a test call to check both sides of the conversation sound right.

Your data stays completely untouched throughout. Speaker and microphone repairs don’t affect your photos, messages, or anything else on the phone.

Most speaker repairs are done same day. Parts for common iPhone and Samsung models are usually in stock. Less common models might need a day or two.

iPhone Speaker Repair

We repair speakers on every iPhone model from the iPhone 7 to the iPhone 17 range.

iPhone speaker issues we see most:

• Earpiece speaker quiet or muffled (very common, especially on older models where lint builds up over time)
• Loudspeaker not working (the bottom speaker handles ringtones, media, and speakerphone)
• Crackling sound during calls or media playback
• Microphone not picking up voice during calls (folk on the other end can’t hear you)

On newer iPhones (iPhone 8 onwards), the earpiece speaker also acts as a stereo speaker for media playback. So if your earpiece fails, you’ll notice music and videos only playing through one speaker at the bottom. It’s subtle at first but once you notice it, you can’t unhear the imbalance.

The iPhone’s earpiece speaker is located near the front camera and Face ID components. We replace it without disturbing Face ID. The loudspeaker is at the bottom next to the charging port and is a separate module.

For microphone issues, the iPhone has multiple microphones. The main microphone is on the charging port flex cable at the bottom. There’s also a microphone near the rear camera for noise cancellation, and one at the top for speakerphone calls. We test all of them to identify which microphone has failed.

If your iPhone speaker is muffled rather than dead, it might just need a clean. The speaker grilles on iPhones are tiny and clog easily. The earpiece grille in particular picks up skin oils and makeup from being held against your face during calls. We clean them out carefully without damaging the mesh. If that fixes it, the cost is much less than a speaker replacement.

For broader iPhone repair issues alongside speaker problems, we handle those too.

Samsung Speaker Repair

Samsung phones use quality speakers, but they’re just as susceptible to failure from drops, water damage, and general wear.

We repair speakers on all Samsung models. Galaxy S series, A series, Note, Z Flip, Z Fold. The models we see most for speaker issues are the S21, S22, S23, S24, and A series phones.

Samsung speaker issues we see:

• Loudspeaker distorted or crackling (often after minor water exposure that the user didn’t think was serious)
• Earpiece speaker quiet during calls
• Microphone not picking up voice
• No sound at all after a drop

For Samsung speaker repairs, we use Samsung service pack parts. The speaker modules are designed to work with Samsung’s audio tuning, and aftermarket replacements don’t always match the same sound quality or volume levels. Samsung’s Dolby Atmos processing is calibrated to the original speaker specifications, so genuine parts sound noticeably better.

On Samsung phones, the microphone is typically on the charging port flex cable (same as iPhone). So a microphone repair usually means replacing the charging port assembly. We use Samsung service pack assemblies for this.

The Galaxy Z Flip and Z Fold have speakers in different positions due to the folding design. We repair these too, but the parts are more specific and can take a bit longer to source. For broader Android phone repair, see our dedicated page.

Google Pixel and Other Brands

Google Pixel speaker repairs use Google service pack parts. Pixels have good speakers and when they fail, you want genuine replacements to maintain the audio quality. Pixel phones had a known speakerphone software bug that was patched in late 2025. If your Pixel speakerphone is playing up, make sure you’re running the latest software update before assuming it’s a hardware fault.

For Huawei, OnePlus, Xiaomi, and Motorola, we use quality aftermarket speaker modules and charging port assemblies (for microphone repairs). Parts for less common models may need sourcing, but we’ll tell you the timeframe upfront.

One thing to note: on some budget phones, the speaker modules are soldered directly to the board rather than connected by a flex cable. iFixit’s repairability index rates phones partly on how accessible components like speakers are. This makes replacement trickier but not impossible. We’ll let you know if your specific model has any complications before quoting.

Whatever brand, we test everything after the repair. Call audio, media playback, speakerphone, microphone. You’ll hear the difference before you leave.

Water Damage and Speakers

Speaker grilles are the most exposed openings on your phone. They’re designed to let sound through, which means they also let moisture in. Even phones with IP68 water resistance can develop speaker problems after water exposure, because the speaker membrane needs to vibrate freely and can’t be fully sealed.

Water damage to speakers often shows up gradually. The phone gets wet, the speaker sounds a bit odd for a day or two, then seems to recover. But moisture that got past the grille sits on the voice coil and starts corroding the fine copper windings. A week or two later, the speaker starts crackling. A month later, it cuts out entirely.

If your phone has been in water and the speaker isn’t right, don’t wait for it to “dry out.” The membrane might recover, but the corrosion underneath won’t reverse itself. Bring it in and we’ll clean the speaker housing and assess whether the module can be saved or needs replacing. The sooner we get to it, the better the chance of a cheaper fix.

Common culprits: rain on the speaker grille while using the phone outside, splashes in the kitchen, steam from bathrooms, and phones left on wet surfaces face-down. You don’t need to drop it in the bath to get water damage to the speakers. For full water damage repair, see our dedicated page.

Preventing Speaker Damage

Keep the volume reasonable. Playing music and videos at maximum volume wears out the speaker membrane faster. The tiny speakers in phones aren’t designed for sustained full-volume output. If you need it louder, use headphones or a Bluetooth speaker.

Clean the grilles regularly. A quick brush with a soft toothbrush once a month prevents lint from packing in and muffling the sound. It’s the easiest maintenance you can do and it prevents the most common speaker complaint.

Keep moisture away from speaker openings. Don’t leave your phone face-down on wet kitchen surfaces. Wipe rain off the speaker grille before putting it in your pocket. After using it in the bathroom, let it air out.

Use a case with speaker protection. Some phone cases have raised edges or mesh covers over the speaker grilles that prevent debris from getting in while still letting sound through. Worth considering if your phone lives in a dusty pocket or a bag full of lint.
