Symptoms
- Charging feels intermittent
- Speaker sound is slightly muffled
- Buttons feel less responsive than before

Likely causes
- CommonNormal accumulation from pockets, bags, and daily useFabric lint and environmental dust naturally collect in every opening over months of use.
What to do
- Power off the phone before cleaning any openings.
- Use a flashlight to inspect the charging port, speaker grilles, and microphone holes for visible buildup.
- Clean each opening with short bursts of compressed air held at a slight angle.
- Use a wooden toothpick or soft dry brush for stubborn debris in the charging port — never metal.
- Wipe down buttons and seams with a dry microfiber cloth.
- Make this a monthly habit if you don't use a case, or every few months if you do.
