Couldn’t find the link, but the attached pics are what I did.
Step 1. Open App,obviously.
Step 2. Click top left “menu” button.
Step 3. Click on the About tab, which is an circle with an i in it.
Step 4. Click on Firmware Upgrade which should be in the center of the screen.
Step 5. Click the “Look for available updates” box.
Apparently, my phone sucks and slips out of the app and back to my main screen when I do this. But if I do it a few times, then go back into the app, I’m updated and ready to go. The other guys around here are MUCH better in deciphering problems and issues, just telling you what I did to fix my issue.
