WAS Great most of the time. once in awhile it takes several minutes and upto an hour-ish to send a message to some contacts. I don't know if it's the contact,. the app, my phone or due to poor service and signal. It's now 2 years later and I don't use the messages app at all, I'm unable to uninstall it completely but find when I uninstall the updates and set my default to current app i use for text & calls, it continues to Switch back to the preset defaults. Is there a way to stop this or no?
