I bought a Galaxy Tab S 8.4 from Curry's which went faulty. The battery percentage would fluctuate massively within seconds of unplugging the tablet as well as restarts and screen artifacts etc. The tablet was only usable tethered to a charger. As per advice from other forum members in another post, I accepted Curry's offer to repair under warranty, even though I initially requested an exchange under SOGA as it was the responsibility of the retailer to repair the goods without causing significant inconvenience to the customer. I got my tablet back today, with a note inside the box saying that the battery was replaced and the tablet was tested and working. I turned it on in the store and it only had 7% battery left which I found odd since they were supposedly testing the device just a couple days ago. Surely the battery would be charged more than 7%. Especially if a new battery was fitted as they say I brought it home, plugged it into the charger and it shot up to 65% in 2 seconds. I left it to charge for hours and then turned the device on to which I noticed, was in exactly the same situation as it was before. How could they even say it was tested? This is the most obvious issue, and will show itself just by turning it on. since Curry's have failed to repair my tablet when I gave them the chance, am I right in being able to demand an exchange at this point and be able to take them to court if they refuse? Thanks for reading my long story, and thanks in advance for any responses.
