So this morning my Huawei P20 Pro, for reasons I don't understand (I didn't make any changes or turn any notifications on/off), started randomly making 4 beeps every time I lock or unlock the phone, with about 2 or 3 seconds between each beep.
Not only that, it has sometimes happened when using the phone and it also doesn't seem to make the noise every single time I lock or unlock. Probably about 80% of the time it does do it when unlocked/locked.
I'll record the sound when I'm home and update the post with it.
Any help on this would be immensely appreciated.
