Since the 12.3.1 install my iPhone 8 has been glitching
Ever since I did the 12.3.1 install a few days ago my iPhone 8 has been glitching. When i listen to music on the Spotify app it jumps thru and skips songs and suddenly the song will stop and Siri will be triggered even though i didn't say "hey Siri" or push the Home button. Same happens when listening to Pandora music. Both apps have the latest updates from the app store. I have powered off the phone and restarted a couple times and it keeps happening. So is this a 12.3.1 issue or issues with the apps?
