There are 4 versions of gcam 8.2 greatness and I don't see the version for GW1 sensor by Samsung.8.2 works better. You get motion photos with that. Go to gcam updates, look for 8.2 greatness. There are config files, meant for other phones, try to look for ones with the same camera sensor(GW1 sensor, made by Samsung).
There is no direct config made for the edge in gcam. I use natural, because it's supposed to be less phone critical (specific). I tried the A52(samsung) config, it didn't go well. You may have to try other phone's configs, if natural doesn't do it for you. I've switched to the latest ngcam and added the greatness "natural" xml config with it, seems to work well. Gcams, are like a " box of chocolates" , you never know what you're gonna get.There are 4 versions of gcam 8.2 greatness and I don't see the version for GW1 sensor by Samsung.
Could you link me the page of the right version of 8.2 greatness?
