This bug is call ui bug - hard to answer incoming call - when the phone is unlocked.
1. Usability :
Please fix the boring 'answer decline ' screen
The alert box is at the top instead of bottom. I chose Nokia 5.1 because of its small width yet large long screen.
Going to top for answering the call is unacceptable.
The stock Android has this feature but please fix this.
Look at Samsung or iphone for references.
I tried to return the phone just because of this issue. I can't teach my mom how to answer the call in Nokia. She could do that in iPhone and Samsung phones.
Very hard . It is a basic thing.
If she misses the unlocked screen and if she accidentally unlocks the phone it is impossible for her to pick up the phone because it is at the top and she knows only slide to pick a phone or tap at lower left green button.
