I think I made a mistake with Nexus 5x. I waited till Android 6 and Nexus 5+ to try stock Android. Total disaster for me. Even a simple thing like answering a call is a struggle. When the phone is fingerprint locked, the screen does not light up. There is no one touch answer. WTF? I don't want to swipe right or left while I'm eating or driving, thank you! And look at the size of the speaker phone button, and even the call answering buttons. Any fool can make simple things complicated, but ...
I am not new to Android. I've been using Android for years with Samsung Galaxy phones. Those guys figured out how to keep simple things simple. I used to delete all the bloatware and use the UX enhancements. Stock Android is still lacking! May be wait till Android 10.
Think about it. You can use the power button to lock the screen. Use the fingerprint to open it. Set the power button to open the camera on double touch. But no single touch setting to answer a freaking call!
