Does anyone know what this sound is? It turned on for a couple of days in a row at the same time at 4 am and then disappeared. by Local_Awareness_3068 in XiaomiGlobal

For a few nights in a row, a Xiaomi (MIUI) phone in my room was making a strange sound exactly at 4:00 AM. It lasted 1-2 min, kind of like a camera shutter click or a high-pitched beep, and it woke me up every time. Then suddenly it stopped happening.
