Iphone X : Black screen of death

Hello,

Iphone X is stuck on black screen of death since 24 hours. This problem has been occurring after the iOS update 13.6. It has happened several times after the update but has recovered back on its own. This is the third time that the issue has happened and it hasn't gone back to normal yet.

As the stores are shut due to Covid-19 lock-down, I would appreciate if I could get online assistance to resolve the issue at the earliest.

Thankyou,

Regards

Sanika Malvankar
