My daughter and I have HD+ tablets, both unrooted. hers recently has begun saying that certain apps cannot be installed (things she already had but Google tried to update). It frequently pops up saying Google Play itself is not installed but it does open.
I looked at the OS version in settings and it says 2.2. Is this actual android number, ie, Froyo? or is it Nook's version number? It says no updates are available.
So far my tablet has not shown the same problem but I can't see anything she's done differently than I have.
If I have to root I will; I've done my HD so I know how, but she didn't really want it rooted.
