A video circulating on social media is causing much furor among Samsung users. The video claims that there is a chip in all Samsung smartphones’ battery which leaks all private videos and images being taken via the smartphone on the Internet, and even shares them with the government without the users knowledge.
For all those panicked and confused Samsung users, breathe easy, the chip is nothing but a simple NFC chip. It is actually useful, and not at all harmful. It does not spy on you, and certainly does not upload pictures and videos of you on the Internet.
Some OEMs seal the NFC chip in the plastic back of the phone, while some like Samsung hide the NFC chip in the battery. This is done mainly only to urge users to buy an original battery from the company, purely a business centric decision.
Testifying further that Samsung does indeed put its NFC chip in the battery is this Samsung Galaxy Nexus teardown by iFixit. The teardown clearly reveals that the NFC antenna is inside the Galaxy Nexus’ removable battery. The blog reads, “Not only does the 3.7 V, 1750 mAh battery power the phone, but the user manual states that it also doubles as the NFC antenna. There’s a sweet antenna hiding underneath the battery’s shiny wrapper. So if you ever want to buy a replacement battery (and keep NFC functional), ensure that the battery has the antenna.”
We recommend you to not destroy your Samsung smartphone or your battery. Please do not peel of the ‘sticker chip’, as you may accidentally puncture your battery. The NFC chip is harmless and helps you do many cool things like transfer files, and will also enable seamless payment through Samsung Pay in the future. There’s absolutely nothing to worry about here. No one is stealing photos with this hardware.
