Samsung warranty sucks.

Mon problème

My gear 2 had lines going through the screen when on. Samsung wouldn't warranty it because I couldn't find the receipt, (I only had it 4 months, and the lines were not there when I put it on the charger, but were when I woke up)

Ma solution

Super easy. Everything went in very smooth.

Mon conseil

Unless you have done it before, always watch the instruction video.
