So in ending of june or beginning of july IQOO released a patch update where the phone heats up abnormally and a green line comes on the device. As contacting to iqoo officials they asks to contact customer care for resolution but they'll ask charge for the display (happened with iqoo 9t one of my friends device). So I'll recommend everyone not to update your device because it's a faulty update and please ignore this update as far as you can, disable automatic software updates to prevent this issue. I hope this will help everyone.

As you can clearly see the green line on iqoo 9t. I repeat please do not update your device if you care about your phone. Thank you.
