Default [Q] How to prohibit automatic loudspeaker when taking a call

Hello,

I experience the following problem:

When i get called and i take the call, i usually need some time to take the phone to my ear.
In this time the phone thinks it is clever and automatically activates loudspeaker mode, because it thinks i dont have the phone at my ear.
This, indeed, is correct, but i'm just not quick enough to take it to my ear

To my question: Is there an option to disable this automatic loudspeaker activation? No matter how hard I try, i am too slow ^^
