Attachments not sent.

Hi everybody.
I've just installed this application both in the admin and in the target phone.
The target phone is a Samsung Next Turbo GT-S5570I - Android version 2.3.6.
The Admin phone is a Samsung Next GT-S5570 - Android version 2.3.4
"Phone control" works fine, records are very clear both sides (I used strategy 1) with amr format, the e-mails arrive regularly to the mailbox, but without any attachment: they are stucked in the directory /sdcard/Android/data/com.android.service of the target phone. The target phone command "Force forward e-mails" doesn't work but I can delete the entire folder content except the file "session.key" with the command "Cleanup temporary files".
I tried either with the 3G and the wi-fi internet connection. Forward by SMS is disabled.
Have you any suggestion about this issue?
Greetings

Is there a huge audio file in the stucked files? What is the size of biggest file?

Hi LauCass and thanks for your reply.
The size of the files was low... from 10 to 100 Kb. I tried with short calls.
I deleted them. Now the directory is empty.

I've just reinstalled the target application. It appears that it's working fine. Attachments are now delivered correctly.
Now I'm going to make other tests. I'll let you know the results.

Ok, I hope it will continue to work fine.
