I advise acquiring information first before giving a very low rating to this product.✅️ Now about this sucker, As soon as I inserted this microSD card into my phone, Android formatted it and created folders/directories for allocations. In terms of performance, I was surprised to find it faster than Lexar in certain capabilities. I just hope it lasts longer.
