My phone app on my Unlocked S10 does not have an option to turn off or on Assisted Dialing. I have tried contacting Verizon and everything is good on their end. It is something in the phone app not getting activated. I have tried allowing location services for the phone app, clearing cache, swapping sim cards, everything. I just downloaded a Google phone port and the option is there and active. It has to be the Samsung phone app.
