Hi my first post here
I've got a Spark Samsung S5 which I purchased in November last year. A few weeks after getting it I attempted to root it with CF-autoroot, but this was unsuccessfull, however it did burn the KNOX/efuse counter, and so voided the warranty.
The phone worked perfectly for 4 months (suggesting that my root attempt was most probably unrelated) and then the display stopped working. When booting the phone will flash some lines of brown and then go black again and will not show anything. I sent it to Telegistics the Spark samsung repairer via my local samsung booth, and they have said it will cost $250 to fix and will not be covered by warranty because I voided the warranty.
I understand that the warranty is void, but it seems to me like it becomes a matter of the Consumer Guarantees Act (CGA), because if the phone screen stops working after 4ish months of use then it was not of acceptable quality, and I shouldn't have to pay for repair/replacement.
Does this seem like a valid case to you GZ's or have I misunderstood the CGA?
