HOTSPOT & Wifi cannot ON , and Camera don't flip

[MITbolts]

I Love Asus Products, I have Asus Laptop and 2 Phones before, and it's working perfectly ...

Then I Purchased this Asus 8 Flip Last year . I was amazed how Flipping camera work,  until one day Its Slow uploading,  then Stop Hotspot & Wifi , even the Camera Flipping is Not working..

I've done everything to fixed this , Factory reset, Reboot . But nothing works .

I am so disappointed with this Product . 

Hope someone can Help .

Do I need to Fix this Phone ? ( with this kind of problem) or just buy New , Try Another Brand .

Thanks.
