Hello K4vikes,
Your iPhone should return to the screen that it was on before you placed the call. For example, if you tap call from the Contacts tab, it will go back to the Contacts tap. If you call from the Recents tab, it will go back to Recents.
It sounds like your primary concern is that a new call is initiated when you disconnect from the current call that you placed from the Recents tab. If this is the case, you might consider one of the settings outlined in Adjust how iPhone responds to your touch. Adjusting the required touch duration or pressure may keep you from accidentally placing a call when it moves to the next screen.
Adjust settings for taps, swipes, and multiple touches
1. Go to Settings > Accessibility > Touch > Touch Accommodations, then turn on Touch Accommodations.
2. You can configure iPhone to do any of the following:
* Respond to touches of a certain duration: Turn on Hold Duration, then tap - or + to adjust the duration. (The default is 0.10 seconds.)

Adjust settings for touch-and-hold gestures
The touch-and-hold gesture reveals content previews, actions, and contextual menus. If you have trouble performing this gesture, do the following:
1. Go to Settings > Accessibility > Touch, then tap Haptic Touch or 3D & Haptic Touch.
2. Choose the touch duration—Fast or Slow.
3. On an iPhone with 3D Touch, you can also choose the pressure needed—Light, Medium, or Firm.
4. Test your new settings on the image at the bottom of the screen.
All Our Best.
