Hi, can anyone tell me where to put this little white thing? i took out the battery and all of a sudden there was a white plastic thing on my desk. I can’t find out where to put it back. Sorry, the image isn’t sharp. The phone is without this working.
I can’t find it, but we had the same question a couple of weeks or months ago. If my memory doesn’t play tricks with me, @paulakreuzer actually found out the location of that thingie in his phone and took a photo of it. Or maybe someone else … 
I believe others reported that their Fairphones did NOT include it and they worked nevertheless.
