Phone calls dropping

Is there a software update for your phone? I had a similar problem with my iPhone and a software update fixed it.

 

I suggest that you borrow a different type of phone from someone else just long enough to prove whether the problem is with the car or the phone.......because Toyota will blame it on Samsung and Samsung will blame Toyota.

Wild guess: Do you have another bluetooth device present that might be interfering with the connection to the phone ??

 

You could try deleting the phone on the Prius and forgetting the Prius on the phone, then repairing everything. Sometimes that works.

Maybe Toyota has a firmware update to the head unit to address the issue?

 

I have a Samsung Galaxy S20 Ultra and have never had an issue. Perhaps you are accidentally touching the touchscreen on your phone? It sounds like there is something trivial going on. Bluetooth on these cars simply works.

 

Yep I had this problem with my 2014 Tundra and checking for and installing software updates did help but, also, deleting the phone entirely from the system then reconnecting everything seemed to make the dropped calls decrease.
With the Tundra, not only would it drop calls, it would completely reboot itself while driving...sometimes rebooting 3-4 times in a 45 minute span. VERY annoying!!

 

Been having the same issue as well as those that ColoradoBoo is having. Resetting the whole system in the middle of a call. Ending calls. not being responsive when using the touchscreen in the car. They've updated the software twice and are trying a hard reset today. Let's hope it works. But I know of at least one other person having this issue with a newer 5G phone. The phone companies are blaming Toyota as the phones don't drop calls, etc. when they are not connected to the car bluetooth. Nor do they when connected with other bluetooth speakers/headphones, etc.
