I recently opened up my galaxy s6 to perform a motherboard replacement and in doing so, found three orange stickers with the name ZF-N4 on it. My question is how important are they? Would they cause my phone to not connect to the internet or network if they were to get damaged?
Hi Mustafa, in the case of my phone, it was labelled ZF-E4 - if you’re speaking of the same ribbon sticker on the side, it is the Wi-Fi antenna, if damaged it might still work by pressing it down into place, but if completely broken off, it will indeed cause wireless connection to stop working.
