Fantastic work! I’ll be straight with the feedback and try to visualize it.
Slide 1: Its clean, minimalistic, but - it only has 3 colors. How it would be if the numerical font has one of nothing’s colors say for ex: the yellow we see in the special edition. also, the * can be yellow and the num pad dialer instead of grey can it be the deep blue color as seen in the blue phone 2a? the contacts font in dialer and Contacts word in list are two different fonts, can they be of same font and size?
Slide2: the quick reply text and icon size is way too small for an average user to look at it, if they can be scale up 4x for better readability. also add a Mute icon next to quick reply or both can be placed side by side to allow user to choose if they wish to mute by a simple tap, its obvious we have flip to mute but a mute option on screen next to quick reply makes sense as no other dialer does it.
Slide3: the typical dialers we see have either sliding function to answer or reject call or swipe or tap any of the icons shown in the next screen. Can we think of a new concept out of the standard behavior. Like, Text instead of Icons. A simple prompt of words on screen saying - Incoming Call with two options: Accept Call or Reject Call - just fonts and no icons. like a simple tap function instead of sliding or swiping that we all have been doing from past 2 decades.
Slide4: the white speaker icon can it be yellow just to bring more highlight?
I am looking for a Nothing dialer that should look like Nothing and not something we have already seen or been seeing from all these years in every device. Your minimalistic approach is very sharp and clean but font choice, color and text sizes and their alignments play a major impression to overall experience. What are your thoughts?
