Question How to make and answer calls on a car tablet connected to a phone?

[grahamf]

I got an aftermarket stereo for my car that is a full fledged android tablet, it has something called zlinks which handles android auto, but is there a way to connect it to my phone via Bluetooth to make and receive calls without having to launch android auto all the time?

What phone do you have?

What tablet/head unit do you have?

Google says this.

To make calls from a tablet using a connected phone, you'll need to utilize features like Call & Text on other devices (for Samsung devices) or Wi-Fi calling, or VoIP apps like Google Voice or Skype. Some carriers also offer features like DIGITS (T-Mobile) or Apple FaceTime that allow you to make calls from other devices using your phone's number. [1, 2, 3, 4, 5]
Detailed Steps (for Samsung Galaxy devices):

1. Log in to the same Samsung account: Ensure both your phone and tablet are logged in with the same Samsung account. [2, 6]
2. Enable "Call & Text on other devices": On both devices, swipe down from the top to open the quick settings panel and tap the "Call & text on other devices" icon. If the icon isn't visible, you might need to add it to your quick settings panel. [2]
3. Connect via Wi-Fi: Ensure both devices are connected to the same Wi-Fi network. [7]
4. Call & Text: You can now make and answer calls or send messages from your tablet using your phone's number. [2]

General Options:

• Wi-Fi Calling: If your carrier supports Wi-Fi calling, you can make and receive calls over Wi-Fi using your tablet. [5]
• VoIP Apps: Apps like Google Voice, Skype, WhatsApp, and Facebook Messenger offer internet-based calling and messaging. [1, 3, 8]
• Mobile Hotspot: You can use your phone's data connection to make calls on your tablet via a mobile hotspot. [9]

I guess it will depend on if the tablet is truly a tablet or if it is a head unit. Many smart head units look like tablets, allow users to install apps the way you might if it were a tablet but at their core they are different than an actual tablet.
