Perhaps this is the way to go to make this tablet suck less, but I would recommend switching to a windows tablet, either a Rt-based or a x86-based tablet. Back when galaxy tab 2 10.1 came to the stores, I went ahead and got one.
And that was a decision I soon came to regret deeply. Android is simply not comparable to windows, not even on a tablet.
So I went to buy a hp elitepad, running windows 8 pro. This impressed me so much that I also bought an Asus vivotab Rt.
The fact that the elitepad is running x86, means that I now will install virtualbox, and then install android for x86.
And perhaps mac os, windows nt, bsd or Ubuntu. Time will show.
My point here being, it is better to start with a superior os and then install the inferior ones, instead of doing this in reverse.
