hrry thanks Mate fr ur response ,but evn initially I thought cd be sweat or body oil , so it was it it a wet cloth n kept it aside inside my drawer ,aftr 2 3 days I see tht it’s again oily ,
I did a few research on this myself I got to knw tht the oily substance is plactic plastisizer which is used to keep the wires inside durable without any wear and tear
I went to a nearest nothing service centre, but they said it’s a new thing cannot claim any warranty n said to email CMf nothing, which I did ,n waiting reply
