This YouTube video is one of several showing that, if you open a Samsung mobile phone battery, it contains a "secret chip" and antenna, and suggests it can be used for transmitting your secret data to Samsung.
Is this true?
This conspiracy theory has been widely debunked already. It is obviously false to anyone familiar with the Near Field Communication (NFC) antenna, installed on Samsung Galaxy batteries.
Here are some of the many sources that have quickly responded to these claims with explanations:
While there is a coil “hidden” in the wrapping surrounding most batteries included with Samsung phones, this is merely the NFC antenna and not a “secret microchip” used to steal data.
So please, don't try to pull the sticker off of your Samsung battery. Don't let anyone you know try it either, the risk for accidentally puncturing your battery is just too high. That chip is not harvesting your data in any way,
Inside your smartphone, hidden underneath the sticky plastic wrapping of the battery, or glued to the removable rear cover, there’s a secret, ominous-looking wireless chip. It’s not controlled by the FBI or the government or the Illuminati, though, and it’s not tracking every search you make online — it’s just NFC.
If you are a Pakistani and have received the above said video through your friends on social media, dont believe in the silly stuff the two gentlemen in the video are preaching and thereby destroy your NFC chip.
No it is not some super secret chip put there by Samsung to track your every move and steal all your videos and photos. It’s an important part of the phone that you’re tearing out and is probably a really dumb idea to do that. So you can rest easy Internet, your Samsung phones are not being controlled by Samsung and your data is just fine.
Basically, there's a video of some guy claiming the Samsung NFC sticker wrapped around his Galaxy S4's battery is a government or corporate surveillance device placed there to steal all your photos and monitor all your phone calls. It is completely, utterly false and also surprisingly bigoted (!), so please note that this video is probably best tagged NSFW for language / anti-Semitism.
The man peeled off this sticker on his phone’s battery claiming it is helping the company collect data on his his photos. What the sticker really holds is NFC technology, which allows users to do a variety of cool things, like mobile payments for example.
Unfortunately, what he is saying isn’t rooted in any fact. The piece inside is an NFC antenna, which powers Near Field Communication features. If you’ve ever used your phone to tap to pay at a cash register or put your phone back to back to another phone to exchange a file or picture, you’ve used it.
