Switching to iPhone Speaker function
When someone calls me (iPhone 17.4.1 iOS) while I’m in another APP, such as Kindel, I can answer the call by clicking on the phone “answer” Icon in the upper right corner of the screen. But being hard of hearing I need to then get to the speaker function. I tried to find a way but failed. An explanation of what steps to follow to get there (to the speaker) from any APP would be helpful.
