Concept Dialer for Android: Call Recording, Transcript Search, and T9

⚡ The gist in 5 seconds

• A designer going by neonoviy posted a concept of a "Phone" app for Android on Habr — with recording of any call and search across conversation transcripts.
• The interface is built from Material Design components, and the color theme adapts to the home screen wallpaper.
• The app doesn't exist: these are mockups, and the author himself calls the dual-SIM support and the settings screen unfinished.

🔍 What happened

The author started out helping a former colleague with the design of his dialer, but along the way the feature set grew — and it turned into a reflection on what a convenient dialer for Android should look like. It's an article on Habr that takes three minutes to read; a video of the prototype is in the author's portfolio, not in the post itself.

There's plenty of specifics in the concept. Answering and rejecting a call is always a swipe right or left, with no "sometimes a button, sometimes a gesture" variations. Tapping a contact row always opens the full contact card rather than immediately calling: the author calls this unification and protection against accidental calls. Below the numbers in the card there's a brief call log — it shows which of the contact's numbers is actually active. Avatars for incoming and outgoing calls differ in shape, unknown numbers are labeled, so a missed call from a courier doesn't drown in spam. Every conversation is recorded, recordings live in a separate section, and speech recognition enables search across conversation content. Dialing uses T9 over contacts, like on old keypad phones.

🧠 Our take

What grabs us here isn't the feature set but the fact that the author designed not "features" but stressful scenarios. Swipe always and everywhere, card instead of call, all options on the in-call screen — no need to dig into "additional settings" to turn off Bluetooth headphones or add a second caller. These are exactly the spots where the stock Android dialer usually gets frustrating: the logic jumps from screen to screen while you're talking to a person.

It reads like a jab at Google, though the author never states it outright. Our assessment: call recording and transcript search are both the most interesting part of the concept and the most problematic. Recording on Android has been stymied for years by system restrictions and varying legislation: in some places you can't record a conversation without the other party's consent. The author draws the interface but doesn't answer how this would work technically or legally.

The main beneficiary of this concept is the designer himself — it's a strong portfolio piece. The losers, by our logic, are those waiting for a ready-made app: there's no code, and at the end the author explicitly invites anyone who wants to build it to get in touch. In other words, this isn't a product but a pitch for collaboration.

⚠️ What we don't know

There are plenty of weak spots, and the author admits some of them himself: dual SIM is barely accounted for, settings aren't fleshed out, "Favorites" could arguably be a separate tab — meaning the solution isn't final. We haven't seen the prototype in action, any measurements, or any code: only the description and a portfolio we haven't looked into. How call recording would behave on real Xiaomi, Samsung, or Pixel firmwares remains an open question.

Prediction: within a quarter, some Habr reader will build a working prototype from this concept with at least T9 and a call log. If that doesn't happen, the topic will remain a portfolio case with no follow-up.

Disclaimer: there is no official app; everything described is a concept and mockups by a single author.
