This was happening to me only when my phone was in my pocket with the screen off.
I would hear it start dialing, pull it out and find the dialing pad was up with this "emergency dialing" feature happening.
But I found a setting called "accidental touch protection" that you can just search in settings.
It protects the phone from accidental touches when in dark places like pockets.
Haven't had an issue once since I turned that on.
Don't know if that's the issue you are describing or not.
Sorry, can't help you if this is happening randomly while you are using your phone.
That's never happened on my Note 10+.
I first noticed it when playing brick breaker quest..so initially thought it had something to do with that..but then realized it happens whenever it wants no matter what I am using..not sure how to check in safe mode
Safe mode would help us narrow down if there is a third-party app causing this. To enter safe mode:
So I used it In safe mode and it didnt happen...went back to normal mode and deleted some apps that i had downloaded and so far no pop ups..thanks for the assistance..hopefully that resolved the issue
