Android/Huawei Camera Slow Loading, a Systematic Problem?

[Jingtian Wang]

I've had my Huawei P20 lite for about 1.5 years now, and one of the biggest problem that annoys me is the speed which the camera loads, it takes anywhere from 2 to 5 seconds to open. Which sounds like little time, but it makes me miss enough moments and making experiences such as snapchat and insta much worse. I tried to clear the camera cache as some suggested, did nothing. I also tried this on a Huawei P20 and a Mate 20 incase it's the problem of the budget phone, same story. 

I remember when I had my iphone SE 1, the camera opens instantly, I already get a image on the screen as I was sliding left on the home screen despite it being years behind on specs. Which makes me question whether it this a problem with the android OS? But I can't make a conclusion as the only phones around the family  are Huawei making my observation a sample size of one. Could other who have different android handsets chime in on this?

My poco f2 pro is about 1-2 seconds no matter which photo app is used. That's assuming the phone is already unlocked though.
