Part of Redmi guides, MIUI guides, 2022 guides.

Here is the situation. Your Redmi K50i came with the Google dialer. It calls people, it works, and it is plain. Somewhere along the way you noticed that the MIUI dialer records calls from inside the app, has T9 search on the keypad, and actually deals with spam. So now you want that dialer, and the only clean way to get it is the official China ROM.

That is what this is about. Not a mod, not a patch. An official build that happens to ship the dialer you want.

What I checked after flashing

• Call recording from inside the dialer, no third-party app involved.
• Spam and caller ID handling on incoming calls.
• T9 search when you type a name on the keypad.
• Dual SIM calls and how the SIM picker behaves.
• Whether contacts merge properly with your Google account.
• The look of it, because the Google dialer is plain and this one is not.

Why the China ROM

MIUI ships different dialers in different regions. The build sold in India and much of the world uses Google's phone app, because that is what Google requires for the region. The China build uses Xiaomi's own dialer, the one with recording built in.

So the goal is not to hack a dialer into your current build. The goal is to flash the official China ROM, which already has it, and then put your Google apps back on afterwards.

Before you start

• Unlocked bootloader. That is the entry ticket. If you have not done it, that is its own job, and it wipes the phone the moment it unlocks.
• A full backup. The flash wipes the phone again. Photos, chats, authenticator codes — all of it off the device first.
• The China ROM package for the K50i, plus a flash tool on your PC.
• Patience for the first boot. It is slower than you would expect. Do not panic and start pulling cables.

What actually changes for you

This is the part I want you to read before you commit, not after.

• Region apps and India services disappear. Some things tied to your region simply are not on a China build.
• Google apps may need reinstalling by hand. You will be installing the Play Store and its friends yourself.
• OTA updates come from the China channel, not the India one. That is what you signed up for with a China ROM.
• The Google caller ID that pulls from search is gone. That is Google's smart caller ID, not Xiaomi's. It is the price of the dialer.

What worked well

The MIUI dialer is the reason to do this, and it delivered. Call recording alone is worth it if you actually use your phone for calls. Recording runs from the dialer itself, so you press once and the call records — no extra app, no notification you have to fight.

Incoming call handling felt more useful too. Spam gets flagged in the way you would expect from a dialer that Xiaomi actually maintains for calls, rather than one Google builds for a global average.

T9 search on the keypad is small but you notice it within a day. You type three letters of a name and the contact is there. Going back to anything else feels clumsy.

Dual SIM behaved normally for me. Contacts merged into the Google account without me doing anything clever — it took a minute to settle after the restore, which is normal when you land on a fresh build with a few hundred contacts.

Honest notes

Nothing broke for me in normal use. But this is an official China build, so a couple of region services just are not there, and you will notice them by absence rather than by an error message. If your day depends on a specific regional app, check that it installs before you go all in.

Also, do not relock the bootloader on a China ROM flashed this way. Leaving it unlocked keeps your options open if you want to go back.

If the driver and flashing setup on the PC is the part you do not enjoy, the free Rom Flasher tool on GitHub bundles the ADB and fastboot driver install into a couple of clicks so you are not hunting Device Manager. The link is in the downloads section.

Full description from the video

The whole point of this one is simple. Getting the MIUI dialer onto a Redmi K50i that came with Google's phone app. The route is the official China ROM, and yes, it works.

📱 Device : Redmi K50i

🧩 ROM : MIUI China ROM (official)

🎯 Goal : MIUI dialer instead of Google dialer

🔬 What I Checked

• Call recording from inside the dialer, no third-party app needed
• Spam and caller ID handling on incoming calls
• T9 search when you type a name on the keypad
• How dual SIM calls and the SIM picker behave
• Whether contacts merge properly with your Google account
• The look of it, because the Google dialer is plain and this one isn't

📊 Verdict

The MIUI dialer is the reason to do this flash. Call recording alone is worth it if you actually use your phone for calls. The flip side is that some Google-side smarts disappear, like the caller ID that pulls from Google search, and your contacts need a minute to settle after you restore them. Nothing broke for me in normal use, but this is an official China build, so a couple of region services just aren't there.

🧩 Before You Start

• Bootloader unlocked, that's the entry ticket

⚠️ What Changes for You

• Region apps and some India services won't be on the build
