So, my dad is 88 and living in an assisted living facility. We have struggled with basic AT&T cell phones for the last few years in that he is always "fat fingering" the volume control on the side and turning either/both the ringer volume down or the earpiece volume down by mistake to make the phone non-functional. If I could super glue the volume control once both are turned up to "full" I would and may just do that! My question: Does anybody have any basic cell phone product ideas that I could look into that allows me to "lock" these functions so they can't be changed? He has NO need of texting, taking cell phone pictures, or any of that fancy [censored]! It sure seems like even the "senior" cell phone company and providers really don't know their market and keep trying to put more technology into these phones. They just don't understand that basic, no frills phones (I'm talking about flip phones here as well) are really what is needed for a large group of seniors. Help please!!
