I am not at all pleased with the new Samsung update.
When I receive messages using Message+, initially, once I read the message, the icon number would not erase. I had to uninstall and update again for the message number to disappear. Now, when I receive a message, I will hear the ringtone, see the icon in my top bar, but the icon badge number may or may not appear.
I am no longer able to click on the Pandora widget to launch my app. I must now go into the apps to launch it. I have done an uninstall and installed again and it still didn't work.
When my phone connects with the Bluetooth in my car, song titles and artists through Pandora or Apple Music used to instantly appear on my sceen. Now it doesn't even read the music that is playing.
Please help.
