Your phone has a hardware defect, I went through the same exact thing. Please see my post, and you will understand why your best bet is to file a claim rather than send it in to repair.
Consider these two paths:
1) You decide to send in your phone for repair. You will send it and you won't hear anything back for 2-3 weeks. When you do, you will wake up to an email at 6AM that basically says the issue is your fault and you have to pay $300-$500 to fix. Whether or not you decide to pay, you won't get your phone back for another 2 weeks.
Nothing was accomplished here except either a month and a half of your time wasted, OR a month and a half of your time wasted PLUS $300-$500 less in your bank (that you shouldn't have even paid)
2) File a claim with your bank, explain to them that based on MANY forum posts, this company does not honor it's warranty, and there is no reason for you to send in the phone. File a claim with your bank so that they can refund you your money, and use that money to purchase a much better phone from a different company (I recommend the OnePlus Pro 8 over the ROG II, and I've had three ROGs....). You will get your money back instantly, and depending on where you buy your phone, you could buy a new phone within the same day or purchase from online, and you will be set within a week.
Hope this helps, good luck!
