I recently participated in Weekend Hackathon #104 by UXHack and my redesign was selected among the Top 5 submissions.
Interestingly, I was the only Nigerian designer in the top 5 among a largely Indian participant pool. 🇳🇬
Here’s the thinking behind my redesign.
The challenge was simple but nuanced:
Redesign the incoming call screen for suspected spam calls so that it informs users without scaring them, while still helping them take action quickly.
The original design used a strong red background which felt alarming and stressful.
My goal was to communicate warning without panic.
So I made a few key design decisions:
1) Amber Warning Background
Instead of red, I used an amber tone.
Amber communicates caution and alertness, but it is less aggressive than red.
It signals that something might be wrong, without immediately triggering fear.
This creates a calmer user experience during an already disruptive moment — an incoming call.
2) Clear Social Proof
I added the line:
“Reported by 128 users”
This provides immediate credibility to the warning.
When users see that many others have reported the number, they can quickly trust the alert and make a faster decision.
3) Familiar Call Actions (Muscle Memory)
I kept the call actions green for answer and red for decline.
Most users already associate these colors with phone calls.
Keeping this familiar interaction reduces friction and allows users to act instantly without thinking.
4) Additional Actions: Block & Report
Beyond answering or declining, I added two lightweight actions:
• Block
• Report
This gives users control beyond the moment of the call, helping them deal with spam proactively.
The goal of this redesign was simple:
To Inform, Enable quick decisions & Reduce panic
Designing for moments like incoming calls means respecting speed, clarity, and human psychology.
Grateful to UXHack for the challenge and the recognition.
