When to replace motherboard?
So I messed up and got some water on my phone, and Samsung will not fix it because I tripped the KNOX counter (really stupid of me since I didn't even keep it rooted for more than a few minutes) I went to the samsung store and they "said" I needed to replace my motherboard and LCD for an amazing price of $725. The lcd screen is fully receptive to the S-Pen, but will not work when I touch the lower portion of the screen with my fingers ( the rest seem to be fine) I checked for Liquid damage from the simtray indicator and that seems to be fine. Now I was just wondering if I actually needed to change the mother board or if it was more of a samsung money grab to reset the knox counter? and Could I not just fix this problem by fixing the LCD.
P.S
I've worked at a cell phone repair shop, but i've repaired a few iphones my self, so I am planning to fix the screen my self.
Questa è una buona domanda?
