Bogus Voicemail notifications

[Jobosam]

Every time I toggle on or off airplane mode in quick settings (drag finger down from top of screen on my Samsung Galaxy A13), I get a bogus voicemail notification. By that, I mean that when I toggle off airplane mode in order to look at my voice mails, I see there are no new Voicemails. These bogus voicemail notifications happen every time I turn there a plane mode on and every time I turn it back off again. I am on one UI 6.1 last updated on the 6th of September 2024.

Hello @Jobosam 

Just as a starting point try Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

If i can be of any further help please don't hesitate to ask  😎

Many thanks to BandofBrothers for your suggestion. I cleard the cache partition but it hasn't affected the problem. I still get a notification that I have a new giffgaff voice message, both when I toggle airplane mode on, and when I turn it back off again. On the plus side, I now know to delete the message immediately 👍😀

Well, it's now been a few days since I cleared the partition cash and all of a sudden, I've discovered that the voicemail messages have now stopped, so thank you BandofBrothers 👍😀
