I bought a Samsung smartphone last year and there was a problem with the gyroscope once received. I started a return but then the issue vanished before I sent the item back and I had to cancel the return due that if there is no issue on the returned item I would have had to pay £30 to get it back.
After 3 months the issue came back so I started a warranty return. They first say that it will take 4-6 weeks to repair but as of now they have added further 3 weeks to receive the item, send the item to their hubs, inspect the item. I am now in the 6th week of repair plus 3 weeks of 'receiving the item and checking' and I still don't know when I will receive the phone.
Next time I will rather spend 30£ more and buy it somewhere else than wait all of this time for a warranty repair.
