I have an Android 6.0 phone. Up until recently, I would plug in my phone to my laptop via USB cable and when drag photos/sync music to the micro SD card in the phone with no issues. The USB connection setting on the phone was set to MTP. Now, when I plug in the device, it will charge but nothing will show up. I can access internal storage by changing USB connection settings to PTP and access the microSD in a slower, more of a hassle kind of way by changing the setting to USB storage which has to be turned on/off and the phone has to read every file on the card again each time. I don't know why this happens now. Any help with accessing the SD card the way it used to be, while it's in the phone?
