If I am buying a desire outright, does the included 1 year manufacturer's warranty cover things like this? Also if they do, lets as an example say that the phone develops some sort (any sort) of faults, for example the one above. And lets say that the fault occurs not in a constant but a reciprocal and inconstant cycle, so when I go to the shop to return it, the fault is not present. Will they swap it for a new device? are they obliged to just replace it on the spot? or can they decide to send it to "repair" for a phew weeks? Thanks.
