Weird. My first smart phones were the G1 and G2 (Android, Google Phones, HTC made) and didn't have a flash for the camera, so the "flashlight" was an app that set the screen to full bright white. I think I may have used an aftermarket app then. But since I moved from Android to Apple, I don't think I've ever used any flashlight app other than the built in app.
Most iPhones for many years have had the flashlight on the lock screen. You can go right from the lock screen to use the flashlight. (also the camera)
