Frequently asked questions
Why does my mic work in apps but not on calls?
Most modern phones have 3–4 mics: a bottom mic for calls, a top mic for noise cancellation, and front/back mics for video. If only call audio is bad, the bottom mic (often integrated with the charging port flex) is the culprit — usually a ₹799–₹1,799 repair.
Will replacing the screen fix mic issues?
Sometimes — on iPhones the front mic for FaceTime is integrated into the screen flex. If only video-call audio is bad, screen replacement may fix it. We diagnose first to be sure.
Can water damage cause mic-only failure?
Yes — the bottom mic sits next to the speaker grille and is the most exposed component to liquid. Often the only damaged part. Ultrasonic clean + new mic module typically restores it for ₹799–₹1,499.
