audiostreams remain in target phone, no upload occurs. it is mp4 data, found by musicplayer app!!!
After complete new installation upload worked 2 times. Later same szenario as before, mp4 data remains in root directory of appropriate smartphone, without having changed any configuration inbetween. anti theft 4.0.2.8188
retrieving data (contacts, sms, ....) works fine always.
google drive is deactivated, activation doesn't help.
