The speaker isn't producing any sound, the volume is very low even at maximum, or the audio is distorted and crackling. Before assuming it's a hardware fault, there are a few simple checks to run in order.
First: check the volume and settings Sounds obvious, but it's the most common cause:
- Press the Volume Up button and check that media volume is at maximum
- On iPhone, check the mute switch on the left side — if it's orange, the phone is in silent mode
- Go to Settings → Sounds and check that volume isn't limited by system settings
- Try playing audio from several different apps — YouTube, music, videos — to see if the problem is general or limited to a single app
Second: check the apps Some apps like WhatsApp or Telegram manage audio volume independently from the system. If the problem only happens during calls or voice messages in a specific app, check the audio settings inside that app before concluding it's a hardware problem.
Third: clean the speaker The speaker grille collects dust, lint, and debris over time until it's partially blocked — a common problem, especially for people who keep their phone in a pocket. How to clean it safely:
- Use a soft brush with fine bristles to remove surface debris from the grille
- You can use a can of compressed air held at a distance
- Never needles or sharp objects — they damage the speaker's internal membrane
- Don't blow into it with your mouth — the moisture makes things worse
After cleaning, try playing audio again.
When it's hardware If none of the previous steps solve the problem, the speaker might be physically damaged — from a fall, contact with liquids, or simply wear. Typical symptoms of a damaged speaker are distorted audio even at low volume, crackling during playback, or total silence regardless of the volume.
