after 3 months i fix that probelm.. when i go to service center.. u need to replace motherboard, and it cost 80% of the the price..
i searching some article on internet, and watch some video on youtube.. the possible problem is the RAM. cz the chipset and RAM is piled up into one place.. and when the phone get heat, it can cause problem. for the furture..
1. when charging phone u hv not to play it.
2. setting charging 80%, not 100% on armory crates. and setting heat to low
3. and u need charge when 20% battery, dont 3% battery.
i had problem same with your probelm. first my wifi and hotspot didnt work, "error". and 3 month past my phone suddenly dead, can not to turn on.
solution to make wifi and hotspot working again
1. if ur phone still had warranty, ur lucky.. go ahead to asus center.. they will give u new motherboard
2. if ur warranty is eshausted, go to service phone near you, "the trusted one" and say want to replace ram of ur phone.
if you force it to be repaired in a place where it is not genuine asus (asus center). will void the warranty period.
my asus rog phone 5s.. now work normal.. after upgrade ram from 8 to 12gb. the cost is 1/5 price of this phone, and until now i thik is worh it.
