Many speaker problems can be fixed at home: water in the grille, lint, a wrong setting or a Bluetooth mix-up. Some can’t. Knowing where the line is saves you from wasting time on home fixes or paying for a repair you didn’t need.
Try these first
Before booking a repair, make sure you’ve done the basics:
- Removed the case and screen protector edges near the speaker.
- Turned off Bluetooth.
- Run the Water Eject and Dust Removal modes, speaker facing down, a few times.
- Cleaned the grille gently with a dry toothbrush (see our dust cleaning guide).
- Let the phone dry for a full day if it was wet.
- Restarted and updated the phone.
- Checked mono audio, balance and equaliser settings.
- Used the Stereo Test to see which speaker has the problem.
If the problem is still there, it’s time to consider a repair.

Signs you need a professional
- The speaker crackles or rattles even at low volume after the phone is dry.
- One speaker is silent in the stereo test, with settings checked.
- The sound cuts in and out when you press near the speaker or move the phone.
- The phone was in salt water, a sugary drink or soapy water and wasn’t water resistant.
- Other symptoms appeared too: the phone won’t charge, gets hot, restarts by itself or has marks on the screen.
- The problem started right after a drop or after another repair.
Any of these suggest damage that cleaning can’t reach, or a fault that will get worse.
What a technician will check
A good technician will usually:
- Run the phone’s built-in diagnostics and test each speaker.
- Inspect the grille and mesh under magnification.
- Open the phone and check the speaker module, its contacts or connector, and for signs of corrosion.
- Check the liquid contact indicators, which change colour when they’ve been exposed to water. These are used by many manufacturers to decide warranty coverage.
- Clean corrosion from the board if there’s any, often with isopropyl alcohol and, in some shops, an ultrasonic cleaner.
What the repair usually involves
On most phones, the bottom loudspeaker is a separate module that can be replaced without replacing the screen. The earpiece speaker sits near the top of the display and may require removing the display or a cover plate. Laptop speakers are typically a pair connected by a cable.
Replacement speakers are usually not expensive parts. The cost of the repair depends mostly on labour and on how hard it is to open the device. A phone with a glued back glass or display takes more time and carries more risk than one with screws.
Ask the shop for a quote before work starts, and ask what’s included.
Authorised service centre or local repair shop?
Authorised service centre
- Uses original parts and the manufacturer’s procedures.
- Keeps any remaining warranty valid.
- May be more expensive and take longer.
- May insist on a full assessment, especially if liquid indicators have been triggered.
Independent repair shop
- Often faster and cheaper.
- Parts quality varies; ask whether they use original, refurbished original or third-party parts.
- An independent repair may affect your warranty, depending on the brand and your region.
- Look for shops with clear pricing, a written warranty on the repair and good recent reviews.
If your phone is still under warranty or covered by insurance, start with the manufacturer or your insurer. Note that most standard warranties exclude liquid damage, even on water-resistant phones.
Questions to ask before you hand over your phone
- What exactly is the fault, and how did you confirm it?
- What part will you replace, and is it original?
- How long will the repair take?
- Is there a warranty on the repair? For how long?
- Will my data be affected? (Back up before any repair.)
- If you open it and find more damage, will you call me before doing more work?
Protect your data and privacy
- Back up your phone before the repair.
- Some repairs require you to share your passcode. If you’re uncomfortable with that, ask whether the shop can test without it, or use the phone’s built-in repair or maintenance mode if it has one. Several Android brands now include a repair mode that hides your personal data from the technician.
- Remove your SIM card and any memory card.
After the repair
Test the speakers before you leave the shop. Play music, make a speakerphone call, and run the Fix My Speaker Stereo Test to check both channels. Also check that the water resistance seal was replaced if the phone was opened; many shops will tell you that the original water rating can’t be guaranteed after a repair.
What to expect at the shop
When you drop off the phone, a good shop will usually check the problem with you, explain what they think is wrong and give an estimate. Some can replace a bottom speaker module the same day; earpiece repairs and corrosion cleaning can take longer. If they need to order a part, ask how long it will take and whether you’ll get a call before any extra work.
If the shop finds liquid damage, they may ask you to sign a note accepting that other problems could appear later. That’s standard practice, because corrosion can spread after a repair.
Repair, replace or live with it?
Consider how old the phone is, the repair cost and whether other parts are also worn, such as the battery. A speaker repair is usually worthwhile on a phone you plan to keep. If the phone is several years old and has other issues, compare the repair quote with the cost of a replacement before deciding.
If only the earpiece is weak and you mostly use speakerphone or earbuds, you might choose to live with it for a while. A rattling or crackling bottom speaker is more annoying day to day and is usually worth fixing.

Frequently asked questions
How long does a speaker repair take?
A bottom speaker replacement on a common phone is often quick if the part is in stock. Repairs that involve removing the display or cleaning corrosion can take a day or more.
Will a repair affect my phone’s water resistance?
It can. Opening the phone breaks the original adhesive seal. Ask whether the shop replaces the seal and whether they make any claim about water resistance afterwards.
Can I replace a phone speaker myself?
Some phones are easier to repair at home than others, and repair guides and kits exist. Modern phones are glued, have fragile cables and can be damaged easily, so we recommend a professional unless you have experience.
