My Nexus 4 was just upgraded to the android Kit Kat version via OTA. However, I am having problems with the stock messaging app. No matter what app I choose as the default messaging app Textra or ChompSMS, the pop-up notification for the stock messaging app always shows up, despite the fact that I have already turned the notification off on the stock messaging app. This means I am getting two pop-ups each time I get a text message. While not the end of the world, it is getting to be very annoying. Any suggestions from anyone here on what to do? Thank you in advance.
