FTPES fails on some devices

[support]

Explicit FTP over SSL may fail after AUTH TLS command on some devices such as Nexus One.
The problem comes from SSL handshake when reusing the plain socket for SSL.

Implicit FTP over SSL works fine on the same device.

[support]

It seems to work when FTP server forces use SSL on control channel (data channel is optional).

[DJX]

Unable to connect to FTP server running explicit FTP over TLS on AndFTP v2.9.8 (Droid X).
Hangs after AUTH TLS.

"AUTH command ok. Expecting TLS Negotiation."

Works fine on a PC running FileZilla.
