JiuKong Recorder is a professional video recorder with camera-style controls. Switch lenses, zoom while recording, watch live microphone levels, and get clear clipping alerts while you capture. The portrait layout now shows the full remaining recording time on a separate information row. You can show or hide it in Settings, and your choice is remembered. While recording, a large red REC badge and a red line at the top of the preview show the recording status at a glance. Settings stay open while you change several options, and each value updates immediately. Every popup has an X close button and also closes when you tap outside it. Remote Control: start and stop recording on this phone from another phone on the same Wi-Fi network, with snapshots, recording time, MIC levels, battery and storage left, and optional listening. The phone being controlled asks before anyone connects, shows when it is being controlled, and keeps recording if the remote disconnects.
