There's a good deal of confusion over the meaning of 'warranty' - you are not the only one to be confused.

Most manufacturers provide warranties with their products, and these are in respect of faults in the manufacturing process.

If you buy an item from a retailer however, the sale contract is between you and that retailer, not between you and the manufacturer. The retailer is liable to you for anything that goes wrong within six months of the date of purchase, and that liability continues - with qualifications - for a longer period than that.

Electronic devices are necessarily complex things, and few retailers have the technical resources necessary to effect in-house repairs. In addition, the manufacturer's warranty may be invalidated if a third party attempts a repair, and for those reasons most faulty items end up going back to the maker to be repaired. The retailer may suggest that you deal directly with the manufacturer in order to speed up the process, but if you agree - and you don't have to - it's essential that you make it clear that you do so on the strict understanding that it is at the retailer's request, and that you are not thereby surrendering your rights under consumer law.
