I have an older Tracfone (LG15G) with Android version 4.4.2 on it and have noticed lately that when it blocks a call, it sets the phone sound profile to silent. It didn't do this before and don't know why it has started to do this now. The NMS version I have is 3.21.0.3302. It wouldn't be a big problem except that both my parents are over 70 and I need my phone to be able to ring in case the call and need something. Is there a way to fix this or should I consider getting a newer phone even though the one I have still works fine?
