Hi there,
Thank you for sharing the details. It seems like the save feature works fine on your Galaxy Tab but not on your Lenovo Tab. To fix this, make sure your Lenovo Tab is connected to a stable network, try switching between Wi-Fi and mobile data,You may also restart your device and check for any pending/missing updates from the Play Store (Android)and update your software. You also try to clear the app’s cache and see if that works.
Let us know how it goes.

I intialized my table PC (Lenobo) and all the network, I finally solved proble. I found that the "file edit and modification, save menu of adobe acrobat reader" was created in the tablet setting menu.
I guess Adroid OS is not perfect to perform each app 100%-fully, so best way to fix such an unprovoked error is initialization of tablet. Thanks anyway your kind reaction.
