ZTE Maven 2 User Manual

Hi there. Were permissions allowed on the app after the update?

Try to add the widget again on your screen. Usually, you will have to set it up again each time you add. Let me know how it goes.

Hi Anne. Please contact your carrier to change number of rings before a call goes to voicemail. But AFAIK, it is already set at max by default and the option to adjust it is no longer allowed.

Go to Settings > Apps > Downloaded > check each app if there's an option "move to SD card"
