papatech "c.p."
i just had an incident with my Galaxy S3 phone however where the chip became corrupt.. Is it the chip? Is it the phone?  I put one of these in my Samsung phone and another in my Samsung Tablet.  All is well except for that one time where the chip and phone got funny with each other and I had to erase all my music... The phone was able to format / erase / prepare the chip so it was immediately usable but I did lose my music.  Very weird.  Well, all I have to do is sync my music to my phone.. No big deal..
