hy guys please help me .. i have 16gb micro sdcard in my indriod cell phone. when i am formatting the card it shows an error "sd card read only cannot format " . what should i do to uncheck readonly property.
Regular SD cards have a slider that can write-protect the device, but I don't think micro-sd cards have one of those (mine don't). In any case, SD cards over 8GB need to be supported by SD-HC (or newer) controllers. It may be that your phone doesn't support SD-HC (high capacity) devices. SD-HC can deal with devices with over 8GB (up to 32GB) of capacity. You would need SD-XC for more than that.
