Why bother with protective case when back cover is so cheap
Been using Note 10.1 for over a year without protective case nor protective film. The whole body is full of scratches and the worst part is the scratches on the rear camera which act like a softon filter.
Changing back cover is easy. Changing both back cover and front capacitive glass pretty much like buying a brand new Note 10.1 (except the s-pen and whatever is stored inside). BTW don't change just the capacitive glass, change the whole LCD set because you'll break the LCD in the process of taking out the front glass anyway.
the SN on the bottom will be gone (there's a 2nd SN on the battery inside) so just keep the old back cover handy, in case you'll need that SN for.... I don't know.
