Hello, my iPhone is behaving strangely the past hour. When I was taking the video, a message showed up saying that there is not enough storage for video taking. Under information, I have about 150MB out of 122GB memory left. I deleted LOTS of 4K video and some photos. I ended up 222.7MB. I tried again. It took a video for about 10 seconds. When I tried to take another video, I got the same error message. Any idea what is going on? It seems that my phone did not release storage properly. Any suggestion on how to fix this? I rebooted the phone already but it does not help. Thanks.
