I have a a phone Lenovo K3 Note. I noticed something paper like stuck on the back cover of the phone. It is like a film, found on clothes of some stores so that no one can steal them. But what its use on my phone, I couldn't understand. These are the images of the sticker:
Stuck on the cover
Upper side
Was stuck like this
Do anyone know why it is put there, I am little suspicious about it.
It may be just a sticker to counter radiation, as @Andy Yan said. I tore off the the sticker there was just some black slippery substance coated. There was nothing like the stickers on clothes bought from few stores. (So its not the RFID sticker @davidgo)
But, I browsed about such type of stickers, 'Anti Radiation Sticker' there were no supporting blogs or comments about its use found, other than on the sites selling them. Then why the company itself using them? I couldn't understand.
Visit the link, advocating uselessness of Anti Radiation Stickers
Edit - Its not a 'Anti Radiation Sticker', it absorbs dissipating heat, made from graphite while ARS are made of metal.
