For phones that place SIM tray at the top or at the bottom, it’s likely for users to stab the microphone hole or the secondary microphone instead of the SIM tray hole using the ejector tool. A simple google search reveals that the phenomenon is actually pretty common.

If you are reading this, its highly likely that you too accidentally pricked either of the microphone holes. But in doing so did you just puncture through your water resistance grid? Or did you just screw up your microphone hardware?

Who better than Jerry, the seasoned decimator of phones, to answer that.

While dissecting P30 Pro in his recent video, Jerry did answer the burning question.

“The answer is No. Pretty much every phone is built the same way. Microphone hole fits the ejector tool purely by coincidence. But the white impermeable layer (on microphone hardware) is to the side of the shaft and not directly in the end. No matter how deep you go, the tool won’t puncture any of the water resistance or poke the microphone hardware,” he said.

Phew! All is well, then.

In case, you haven’t watched the video already, Jerry also shows what Huawei’s periscope lens assembly for Zoom camera actually looks like on the inside. Pretty interesting stuff indeed!

  1. I just did because i am tired sleepy i insert the wrong hole because it look similar when i tired sleepy then see just 1 second and i worrying my s10.what about s 10?is still safe same with p 30?

  2. Is it possible to angle the ejector tool enough to damage the waterproofing, or do they make it so it is impossible? There seemed to be a small degree of wiggle room when I accidentally stuck my ejector tool into the Huawei p30 pro microphone hole.

  3. Good article – thanks. But what about the microphone at the top? Will it has the same “protective feature” like the one at the bottom if I accidentally inserted a pin into it?
