<div dir="ltr">We are not sure about this, but it might be, that theres a voltage leaking on the EMC-shield behind the microSD - also just a guess, it might be the contacts of the SD-reader that are pretty hard and need a lot of pressure.<br>
But I think only the engineers can make that sure, and it's at least necessary to remove the back EMC-shield to check this.<br></div>
