You plug the mic into your phone, hit record — and the phone ignores it, or the sound comes out worse than the built-in mic. In Anshu's test this happened with an Oppo Reno 10 Pro. Here is why phones do this, and how to find out whether your phone will behave before you spend money.
The most common BOYA complaint from new creators is not sound quality. It is this: the mic and the phone simply do not get along. In the video above, the test phone was an Oppo Reno 10 Pro, and the mic needed a chain of workarounds before it recorded anything. This page explains that fight, so you can judge your own phone honestly.
Anshu connected the BOYA mic expecting the normal routine: plug in, open camera, record. Instead the phone side turned into a troubleshooting session — a compatibility issue serious enough that recording only became possible through a USB hub and adapter, the USB Camera Pro app standing in for the normal camera app, and even a capture card arrangement. None of it was the mic being broken: the same mic worked properly on PC minutes later.
A phone is not a small PC. Its audio system is built around calls first. Three things commonly go wrong with an external mic. First, routing: a mic arriving through a USB adapter may not be routed to your camera app at all. Second, the app: the stock camera app on many models records from the internal mic no matter what is plugged in — exactly why a third-party app like USB Camera Pro, which lets the USB device become the audio source, appears in this test. Third, the model lottery: support differs by exact model and software version, so a mic that works on your friend's phone can fail on yours.
Here is the part sellers skip: if your phone model fights an external mic at the system level, no setting fully fixes it. Workarounds like the ones in this video can force a recording to happen, but they add cost, add steps to every shoot, and — as the test showed — the sound quality can still disappoint. Compatibility is decided by the phone, not by the price of the mic. That is why Anshu's final advice is to choose the mic for the device you actually record on, instead of collecting adapters and hoping.
Sound cannot be judged from text. The video has the live mobile and PC recordings, the comparison with the phone's own mic, and the final buying advice.
▶ Watch Full VideoMost often it is a phone-side compatibility problem, not a dead mic. Many phones do not route a USB or adapter-connected mic into the camera app, or the model handles USB audio poorly. Prove the mic on a PC first — in Anshu's test the same mic that struggled on an Oppo Reno 10 Pro worked properly on PC.
It can force a recording, as it did in this test together with the USB Camera Pro app, but it is a workaround, not a fix. It adds cost and steps, and the mobile sound quality in the test stayed poor even after the workarounds.
Search your exact phone model plus external mic problem, and check whether your recording apps offer an external or USB audio source option. If your model is known to fight external mics, plan for a phone-first mic instead of a PC-style one.
