Ok, so this is a VERY odd issue that's cropped up in the last week or two. My phone dialer locks up and I get a "Phone keeps stopping" alert, but only in one very odd (but common) circumstance. If I "slowly" dial a phone number from my local area code, the dialer locks up after the first 3 digits (303 in my case). If I dial a 303 # quickly, it works fine. If I dial a # from any other area code (including the other local code of 720) either slowly or quickly, it works fine. Only locks up when you hesitate for half a second after dialing 303, like if you're double checking a #. It still does it after clearing the cache and when started in safe mode. I have not yet cleared the "phone" data (green telephone logo), as I'm worried about losing part of my contact list or my rather extensive "block list". This is a Note 8 phone running Android 9.0. Any suggestions?
