Hi,
avast! Backup Beta (4817) tested here on my 5 devices (4 smartphones with GB 2.3.4/2.3.7 resp. JB 4.1.2) and 1 tablet (JB 4.1.1).
Works so far....
BUT:
the selection of files which are backed up by avast! seems to be randomly for each device
e.g.:
i have some apps installed on every of my devices but only on a few a backup was done, the others report
"app file not backed up, app file is copy protected", why?
another example:
one app (a game), was backed up properly for the first time the app was installed, but after receiving an update
for that app avast! suddenly claims the new .apk as "copy protected"
Who's able to explain that strange behaviour?
P.S.: I agree to =YLAP='s suggestion about a notification icon in the taskbar while app is active
