For the last 2 months or so, my screen on my iPhone X locks up, meaning "is unresponsive" for maybe up to a minute or so after I take a photo or video. YES I am using a FAST 64GB SD card. Latest DJIGO4 version and always up-to-date firmware. YES I have plenty of available space on my SD card. Sometimes I even have to QUIT DJIGO4 and restart the app. Any assistance here is appreciated. The iPhone X is 256GB with plenty, over 100GB, of available space.
