Review on Smartphone ZTE Blade A7 (2020) 2/32 GB, Dual nano SIM, blue by Stanisaw Pirkowski ᠌

When a flash drive is connected to a smartphone, the following are copied to the flash drive: files are only small in size, approximately 20MB - 30MB (for example, video clips), and larger files (for example, a movie) are not copied from a smartphone to a USB flash drive and vice versa, i. E. copying hangs by 2% - 3% (once it hung by 12%). I waited for about 30 minutes - copying does not go (does not hang). Flash drives and cable are known to be good (they work without problems on other smartphones). Flash drives were 4GB and 64GB. I tried different file systems on both flash drives: FAT32, exFAT, NTFS.
