Dr. Allwyn Vincent DsouzaMy HUAWEI Nova 5T also heats up when I am using its camera, but it has Kirin 980 SoC inside... so I guess it is normal..
Actually problem is in Snapdragon 855 Image signal processor, it pulls way more power from battery and that's the reason it gets heated fast. We don't have to worry as every Snapdragon 855 device is behaving like this in terms of camera. I compared it with my friends Redmi K20 Pro and results were same, both get heated while using camera . Also OnePlus 7 users are facing this issue. We have to accept it and keep using our mobile rather than worrying
