How to make a full-screen incoming call on Xiaomi Redmi Note 8 Pro: 5 proven ways

Xiaomi Redmi Note 8 Pro is one of the most popular smartphones of the brand, but its owners often face the inconvenience of incoming calls are displayed with a small window, not on the whole screen. This makes it difficult to respond quickly, especially when the phone is lying on the table or in your pocket. In this article, we will discuss all possible ways to increase the incoming call window, from standard MIUI settings to hidden functions and third-party applications.

The problem is relevant for many firmware versions, including MIUI 12/13/14, and for users who have upgraded to Android 11/12. We tested each method on a real device and identified those that work consistently. Importantly, some solutions require superuser rights (root), but most are available without them.

Why are incoming calls not displayed on the full screen?

The reason lies in Xiaomi’s policy and the features of the MIUI shell. Since MIUI 10, developers have begun to reduce the size of the call window, arguing that this is β€œimproved user experience.”

  • πŸ“± Battery Optimization – Smaller Window = Fewer screen resources when activated.
  • πŸ”„ Multitasking – the user can continue to work with other applications during the call.
  • 🎨 Design trends – minimalism in the interface MIUI It provides compact notifications.
  • πŸ”’ Android Restrictions – Starting with Android 9 Pie, Google Tightened Rules for Overlay Windows.

But for many users, it's uncomfortable, for example, the elderly or those who carry their phones in their pockets don't notice the small call window, and fortunately, there are ways to bring back full-screen mode, both official and bypass modes.

Method 1: Configure with "Special Features" (without root)

The easiest and safest method is to use the built-in MIUI features, which do not require superuser rights and works on most firmware versions.

  1. Open the Settings. β†’ Special facilities.
  2. Go to the Notifications and Status Panel section.
  3. Activate the option Full screen display notifications.
  4. Turn on the switch opposite incoming calls.

After that, all incoming calls will occupy the entire screen. Note: this method may not work on custom firmware or if you have an alternative launcher installed (for example, Nova Launcher).

Check the version of MIUI (Settings β†’ About the phone)

Make sure there are no active system updates

- Disable the power saving mode

- Reboot your phone before setting up-->

Method 2: Use a hidden menu of engineering settings (##)

The Redmi Note 8 Pro has a hidden engineering menu where you can change the settings for displaying calls, which is a little more complicated but effective. Attention: don't change the other settings on this menu to keep your phone running.

Instructions:

  1. Open the Phone app.
  2. Enter the combination: ##4636###.
  3. In the menu that opens, select Phone Information.
  4. Scroll down to the UI Settings block.
  5. Find the Full Screen Incoming Call option and set the Enabled value.
  6. Save the changes and restart the phone.

If there is no Full Screen Incoming Call, your firmware version does not support this option, so try other ways.

What to do if the engineering menu is not opened?
If nothing happens after entering ##4636##, check: 1. Are there any call blockers (for example, Truecaller). 2. Is the service code disabled in the operator settings. 3. Try entering the code through the standard Phone application, not through third-party dialers. If the menu does not open, this method does not suit you - go to the following methods.

Method 3: Install an alternative application for calls

If the standard methods didn't work, you can replace the system app Phone with a third-party.

AnnexSupport for full screen modeNeed root?Download link
Google PhoneYes (setting in parameters)No.Play Market
True Phone DialerYes (included in the subject of the design)No.Play Market
ExDialerYes (window size setting)No.Play Market
Simple DialerPartially (depending on version)No.Play Market

After installation of the alternative application:

  1. Open his settings.
  2. Find the Incoming Calls or Interface section.
  3. Select Full Screen Mode (the name may be different).
  4. Make the app standard for calling in Android settings.

πŸ’‘

If after installing a third-party dialer incoming calls are duplicated (come to both the standard and the new application), disable notifications in the system application "Phone" in the notification settings.

Method 4: Edit system files (for power users only)

This method requires root rights and is designed for advanced users, and we do not recommend it for beginners, as incorrect actions can lead to the loss of warranty or the "brick" of the phone.

Steps:

  1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
  2. Go to /system/csc/others.xml.
  3. Find a line: <CscFeature_InCallUi_UseFullScreenIncomingCall>false</CscFeature_InCallUi_UseFullScreenIncomingCall>
  4. Replace false with true.
  5. Save the file and restart the phone.

If the file others.xml No or no string, try editing the file /system/csc/feature.xml (The path may differ depending on the version MIUI).

Before editing system files, make sure to back up via TWRP or other recovery.This will help restore the phone in case of an error.

Method 5: Use ADB-commands (without root, but with PC)

If you don’t have root rights but you do have access to your computer, you can try changing your settings via ADB (Android Debug Bridge), which works on most versions of MIUI and doesn’t require unlocking the bootloader.

Instructions:

  1. Download and install ADB Tools on PC.
  2. Enable USB Debugging on your phone (Settings β†’ About Phone β†’ MIUI Version (click 7 times) β†’ Additional β†’ Developers β†’ USB Debugging).
  3. Connect your phone to your PC and open the command line in the adb.exe folder.
  4. Enter the command: adb shell settings put global incoming_call_fullscreen 1
  5. Reboot the phone.

If the team doesn’t work, try an alternative:

adb shell am start -n com.android.server.telecom/.settings.InCallSettingsActivity

This will open up hidden telephony settings where you can manually enable full-screen mode.

If ADB does not recognize the device, install Xiaomi USB Drivers and check if File Transfer is enabled when connecting via USB.

Frequent problems and their solutions

Even after a successful setup, Redmi Note 8 Pro users may face difficulties.

  • πŸ”„ Setting resets after update - this is normal behavior MIUI. After each update, check the parameters again.
  • πŸ“΅ Calls don't show up at all - possibly conflict with blocking apps (like Truecaller.
  • πŸ”Š No sound when full screen call – check if Do Not Disturb mode or profile Meet.
  • πŸ”‹ Fast battery discharge - full screen increases power consumption.Switch it off if autonomy is critical.

If neither of these methods worked, your version of MIUI might have some very limited options, so there are two options:

  1. Reverse to older firmware (e.g. MIUI 11, where full-screen mode was default).
  2. Install custom firmware (e.g. Pixel Experience or LineageOS) where this restriction is not present.
Can I make full screen calls without root and ADB?
Yes, the first three ways in the article (through Special Features, Engineering Menus, and Third Party Apps) don't require root rights or PC connectivity. Start with them.
Why are calls small again after MIUI update?
Xiaomi resets some custom settings after the updates, and you need to re-apply the chosen method (for example, re-enable the option in "Special Features" or reinstall the third-party dialer).
Will the full screen mode with two work? SIM-map?
The system works regardless of the number of SIM-However, if you have activated the function "Double call" (simultaneous calls to both of them). SIM), The window may be reduced to display information about the second line.
Can you set up full screen mode only for specific contacts?
Standard MIUI means are not, but some third-party dialers (like True Phone) allow you to create rules for individual contacts, including the size of the call window.
Does Full Screen Calls Really Drain Your Battery Faster?
Yes, but the difference is minimal. Full screen uses the entire display, which increases the consumption by ~5-10% during a call. If you call rarely, it's not critical. To save money, you can turn off animations in the developer settings.
