What is the software issue?
Samsung has identified a software issue with certain Samsung A11 phones purchased between July 6th and August 10 th across different wireless providers. If not on updated software, some customers may experience limited or no access to the internet or have trouble making/receiving calls.
Users of the Sprint Visual Voicemail (VVM) application are reporting that voicemails left for them are not always being delivered to the phone.
Please be advised this has been root caused to a bug within the VVM application. If the VVM application is not open or running in the background (if the application is closed), then voicemails are not being delivered as expected.
