I bought a Sero 7 Pro a few days ago. One thing I thought would be simple is copying data files from my Windows 7 PC to the Sero 7 via the USB cable. Small files (up to about 700MB) copy fine, but larger files (1.25GB and larger) cause Windows File Manager to close with an AppCrash error. This happens on both the internal memory and the Sandisk 32GB SD card (in both FAT32 and NTFS).
I've tried both MTP and PTP, and turned USB Debugging on and off in the developer options menu. My Windows PC copies 8GB MKV files to the SD Card (when it's formatted in NTFS) without any problem, and the Sero Pro can play them fine when I move the SD card to the tablet. I'm experienced in Windows, but new to Android. Is there something simple I'm missing? I copy to NTFS and FAT32 non-android devices all the time. Why is the Sero Pro different?
