I swapped out two LGV10's because of touchscreen issues before finding out that FB Messenger was the cause of malfunction.It would work ok for awhile after restarting the phone and then stop responding in the upper part of my screen again.Uninstalled the app,phone works perfectly!
I found my weather choices in my widgets.It isn't viewable in my app pages.
I have ATT,maybe they didn't preload a weather app with the other carriers.
I use Weatherbug as my main app,but the icon on the second screen still uses the default one.
