I tried out the camera with flash on the S4 mini. At first, the LED comes on very brightly for about a second or two, but just before the shot is taken, it comes on 10x EVEN MORE brightly for just a split second. I want to emulate that second level of brightness with a generic torch app, but none of them support the 'second level', only the 'first level'. Does anyone know an app which will reach that extra bright level? -------EDIT After hunting the Google Play store for ages, I came across something which might do the trick. It also allows variable/adjustable level brightness, apparently across all ranges. HOWEVER, you need your phone rooted, and I'm not sure whether it works on the S4 mini (only the S4). There's also a danger that leaving it at the highest brightness for a certain amount of time (longer than the sub-second flash from the camera), may seriously damage the LED: https://play.google.com/store/apps/details?id=com.mohammadag.adjustabletorch To summarize - need more info!
