========================================
For this matter, I updated my ROG phone 5. After I updated it, I noticed that when clicking the power button, it's not functioning well. It's either delayed or not going to sleep mode. After I restart my phone, my phone screen went on and off.
I think there's a bug in the response time to the update that needs to be solve real quick. Or should I factory reset my phone?
