DTEK50, what OTG transfer speed are you getting?

DTEK50
I am using ES File Explorer to transfer files via the micro USB port to a USB 3 stick
The USB 3 stick is a Samsung Duo 128GB

OTG Transfer from internal storage to USB3 stick, 2 MB/s
OTG Transfer from USB3 stick to internal storage, 7 MB/s

what OTG speed are you getting?

It's USB 2, I'll be quite slow lol. For faster and wireless file transfer try
https://play.google.com/store/apps/d...utey.FTPServer

and

https://filezilla-project.org/download.php?type=client
Run Filezilla on your PC and the FTP server app on your phone.
