Hi... Its my first experience with Android.... Two weeks ago I got a Samsung Galaxy Tab 10.1 Wifi .... Two days ago while my husband was doing a search on the Android Market the tablet blocked with the message "Downloading do not turn off target" and we weren't able to "unblock" it again. Samsung service says that the ONLY way that message appears is by trying to update the operating system.... and by doing that we lost the warranty and that repairing it will cost about 90% of the tablet's cost.... ... we had no desire, need, or knowlege to do so.... Is there any way that could have happened accidentally? (Maybe a virus or something like that?) Is there any way we can prove we weren't messing up with the operating system? Thanks in advance.
