Can iPhone (let's say iPhone 6/7/8) run properly if you take out the fingerprint sensor and other "optional" parts such as in-built microphone, gyro, ambient light sensor, GPS, and nfc. If you know the answer about just one or more of these but not all, please do still answer. I just want the convenience without the unessential parts that could provide data to who-knows. I get iPhone is better with security and privacy than others, but i don't want extra "doors/entry points into my home" if I don't need them.
