I've given up!
I'm sorry to say that I've realised that Asus customer support is never going to acknowledge the fault with this phone constantly coming back on in your pocket.
I cannot tolerate it any longer and my work colleagues are fed up of me pocket dialing them every day. I'm fed up of dreading to see what's happened every time I get the phone out of my pocket.
I've not seen a single response from Asus to even acknowledge the situation so I'm going to be selling the phone and going back to xiaomi.
I will never buy another Asus product again :'(
