I do a lot of video recording with my phone in suboptimal temperature conditions. As such, while recording video yesterday, my phone unexpectedly shut down twice while recording in standard battery mode and at a recorded charge level of about 30%. The result is pictured below. I have two video files below that are in my library, but cannot be played or exported. Previously, my phone has managed to save a video before shutting down completely, but that was when the phone was at 10% or less battery. Is there any way I can recover the video files, ideally without visiting a service center?
