Hi shadow, Thanks for sharing these details! Really helped me out!! Maria

Hi Alex, thank you for your answer Problems continued after I started reformatting (it's been 6 months since then). Most of the cards I have been using are SanDisk Extreme. Furthermore, I used only once 5 Intenso microSDXC UHS-I PROFESSIONAL which I can not see in the list of the recommended ones. The ones of SanDisk were used the first 4 times with total success. After that, the unexpected failures started (symchronized with wintertime). In case of corrosion or water damage on the AM PCB what can I do to avoid it apart from using the suggested case? Thanks again, Maria

Hello! Thank you for your answer. Sorry for the delay. Yes, I've been reformatting to exFAT!! At first I didn't but when I was informed about it (6 months ago) I started doing it. So, problems continued without a change. Maria
