Oppo Reno 3's Unwanted Feature Keeps Disrupting My Usage

I'm currently using the Oppo Reno 3, and I'm pleased with its performance thus far. However, I recently ran into a strange and rather frustrating problem. There's this strange feature that I had no idea existed, and for some reason, it's activated on its own. It turns out that the power button, which normally serves to turn the phone on or off, now includes a heat sensor. As a result, whenever the phone detects even the slightest temperature increase, the screen automatically turns on or off. The strange thing is that when this happens, I'm not even pressing the power button. As a result, it's causing a lot of disruptions and making it difficult for me to effectively use the phone. I've looked everywhere for a way to disable this feature, but I can't find it in the settings or anywhere else. It's as if this mysterious feature has its own mind! I contacted Oppo customer service, but they were unable to provide a solution. They promised to look into the problem, but it's been a while and I'm still waiting for a resolution.
