My phone makes a strange noise, what could it be?

[AC Question]

My phone makes a strange noise

ON random occasions my phone makes a noise like it is charging a bomb or something. After this charging sound it reaches a climax and stops. But the phone keeps working. Anyone knows what this might be? Its a SGS5.

Re: My phone makes a strange noise

Welcome to Android Central! It'd be helpful to be able to hear that sound. Can you record a video of it, post it on YouTube, and share that link with us?

"Strange noises" are often due to the NFC chip detecting another NFC chip--the sound is kind of like a series of ascending "bloops." Make sure you don't have anything with an NFC chip (like an ID card or credit card) near the phone--this commonly occurs when people use a wallet-style case for the phone.

Well, i cant record it case i dont know when its going to happen. It really just sounds like a bomb charge in movies. But it doesnt explode, it just stops. This has happened a couple of times now and there wasnt any specific trigger for it. Just wondering if its something to be worried about.
