Thank you so much ASUS
I too got restart and Blackscreen issue for my ROG2 for 6months.
@ARP_ASUS helped me to connect with asus Customer center people. Thanks for that.
Now my device motherboard got replaced and my phone display also replaced since it got wear.
Guys if any your phone is not getting serviced properly then do post it in forum. Let them know and I am sure asus after sales team is great and love to help you.
They have extended my warranty by 3months also, since fixing my device took 40days.
I am really happy with the product.
Then you so much Amol_Gholap for you great help. Kindly convey my thanks to him @ARP_ASUS .
