Samsung Galaxy A36 Plays Random Notification Sounds After Update

I have been experiencing an annoying software issue with my Samsung Galaxy A36 for approximately 10 days. After installing the latest update on my phone, it plays a notification sound every time I turn the phone on or off, even though there are no notifications. Since the sound continues despite there being no alert displayed in the notification panel, I am unable to use the device comfortably.

I also tried performing a factory reset, but the problem continues in exactly the same way. I have not yet contacted Samsung customer service or a technical service center, but I believe this is a software bug that occurred after the update.

I request that Samsung investigate this issue, implement the necessary software fix, and permanently resolve the notification sound problem on my phone.
