My computer uses 1.2.82. My tablet is using the latest android version. Whenever the screen of the tablet is off, the syncing stopped. I have used "better wifi on/off" app to keep WIFI always on and the sync speed goes down to about 6 KB/s from about 1 MB/s when the screen is off. When I turned on the screen, the sync speed immediately jumps back up. Android 4.1.1 on Iconia A210.
