This was suggested by Barry, a Sprint rep and it fixes the problems. You get Sprint zone and roaming settings back, no need to back up your phone, wipe it clean and reinstall updates to fix the problems. Here are the steps: 1. Install the 'Refresh Customization' application from the Google Playstore. 2. Open the Refresh Customization App. 3. Select "Refresh Customization Opt1" to perform ##SCRTN# reset. 4. Select "Refresh Customization Opt2" to perform Chameleon payload refresh. 5. You can uninstall the Refresh Customization App after the refresh option has been performed and the device has rebooted.
