Hi, thanks for checking it. So nothing wrong with the camera itself. I read that the 1.4 firmware beta is ready and some gitup owner are testing it, but the final version will be released soon. I read there are few bugs in the firmware which they will fix. And we can set the custom wb the red and blue between 0-19. Hopefully it will make difference. Ah yes, you ordered it from the USA. Then can you send the dive housing and the red filter back to Amazon? If you keep the eelfilter, I think order one more gitup housing, it is around 9Pounds on banggood or gearbest, I ordered my gitup from banggood EU warehouse which is UK based and keep one housing with the elfilter in and the other without, because I read if you remove and insert too often this eelfilter that thin flap which is on the right side can break off. Also I tested yesterday in our pool the gitup housing, we have around 1.8m deep pool, it was at the bottom for more than an hour and the inside stayed dry and without any fogging up, however our pool temperature is 30°C the outside temperature until I went to the pool was around 7-8°C. So after that I put the camera in, and took some test shots with AWB and the light red and red WB, and the blue sidewalled pool came out yellow or green with the light red and red WB, so I think they are useless for diving and for snorkeling either, so I might order a snorkel filter as well, just in case.
So the gitup housing seems good, but it is difficult to remove the o-ring if it is dusty or they are some specs on it to wash off the dust from the rubber, but at least stayed dry. I couldn't test it deeper, but I read that some of the non-official gopro housing which costs 10-11Pounds leaked only during the snorkeling through the buttons.
