Typical speaker problems on the Galaxy A21s
- Mono speaker at the bottom of the Galaxy A21s silent – speaker module faulty
- The sound booms or sounds scratchy – porous membrane
- The earpiece gives no signal during calls – the upper speaker has failed
- Silent after water contact – corrosion on the speaker flex
- Music only half as loud – dust in the speaker grille
- Distortion at high volume – membrane crack
- The speaker flickers between quiet and loud – wobbly solder contact on the mainboard
How does the Galaxy A21s speaker repair work?
- Diagnosis: which speaker?
On the Galaxy A21s we test the main speaker (music/video) and the earpiece (calls) separately. Often only one of the two is faulty – that saves costs.
- Open the Galaxy A21s back cover carefully
The back cover of the Galaxy A21s is heated to 65 °C, the adhesive layer comes loose. The plastic/glass frame stays dimensionally stable, no prying-pressure damage.
- Release the speaker module from the housing
On the Galaxy A21s the speaker usually sits in the lower housing area, partly fixed with glue. We release it with torque control.
- Install the certified replacement speaker
Original specifications (8 Ohm impedance, Samsung-compatible membrane). Connector to the mainboard, screws torque-controlled, new seal.
- Renew the seal around the speaker grille
Around the speaker grille on the Galaxy A21s the dust-protection seal is replaced. This keeps dust ingress minimal after the repair.
- Sound test at various volume levels
We test music playback, the phone earpiece, hands-free mode and the sound character. Only after a full test does your Galaxy A21s come back.

Frequently asked questions about the Galaxy A21s speaker replacement
What does the speaker repair cost on the Galaxy A21s?
The Galaxy A21s speaker replacement costs €39 fixed price at Reparo in Vienna. Included: replacement speaker unit, new IP68 seal, installation, sound test, 6 months warranty. The 25 EUR diagnostic check is waived on an order.
Do I have to replace both speakers on the Galaxy A21s?
The Galaxy A21s has a mono main speaker at the bottom plus an earpiece at the top. Both can fail separately – we only replace the affected one for €39 fixed price. For both at once a package price arises after the diagnosis.
Earpiece broken vs. main speaker – how do I tell the difference on the Galaxy A21s?
Test: play music/video. If it crackles or is quiet → main speaker. Call someone and speak without hands-free – if you hear nothing → earpiece. Silent in both tests → both faulty or a software problem. We check that in the diagnosis.
How long does the Galaxy A21s speaker replacement take?
The Galaxy A21s speaker replacement takes 60–90 minutes of pure work at Reparo. With the pickup service in Vienna you often get the device back the same working day. From the provinces a 2–3 working day total process.
Does the water protection remain on the Galaxy A21s after the speaker replacement?
Yes. We renew the complete IP68 seal around the speaker grille. After installation full protection against splash water again. Avoid active diving after housing work in general.
My Galaxy A21s crackles during calls – is that the earpiece or software?
In 90 % of cases: the earpiece membrane is damaged (pressure, moisture, dust). Software problems resolve after a restart or factory reset – if the crackle remains, hardware is due. We test that in the diagnosis (25 EUR, waived on repair).

Reparo has no on-site customer access. You book an appointment online – our courier comes to your address in all 23 districts of Vienna (1010 to 1230). From the provinces insured shipping, return shipping in the price.

Do I lose the Samsung warranty through the Galaxy A21s speaker replacement?
The Samsung warranty has expired on most Galaxy A21s devices after 2 years anyway. The Reparo warranty on the new speaker applies for 6 months from installation – on speaker and labour.
Is the Galaxy A21s speaker replacement still worth it in 2026?
Yes. For €39 fixed price you get full sound again – vs. a replacement device (used device from about €119). The Galaxy A21s is still partly supplied with updates by Samsung.
Why is the speaker in the Galaxy A21s prone to dust?
The Galaxy A21s has a more openly designed speaker grille on the bottom that directly attracts bag and trouser-pocket dust. We renew the grille during the repair to minimise dust ingress.

Yes, for €39 fixed price you get full sound again. A replacement device from the same class costs €150–200 (used) – the repair is significantly cheaper.
