Modern Xiaomi smartphones, which are based on MIUI shells or the new HyperOS, have an aggressive spam protection system that often conflicts with third-party number detectors. Users installing the popular Get Contact app often face a situation where the system ignores its database, continuing to call spam or not displaying the caller’s name, this is because Android does not allow several applications to simultaneously intercept an incoming call for identification.
To make Get Contact a major determinant of conflict with Google’s standard service or Xiaomi’s built-in analyzer, you need to make a number of specific adjustments. Simply installing an app is not enough; you need to force it to prioritize your security. In this article, we will examine all the nuances of access rights settings that are often hidden in the deep privacy settings menu.
Owners of Redmi, POCO and Xiaomi devices need to understand that battery optimization algorithms can turn off background processes of the detector on their own. So comprehensive setup includes not only selecting the default application, but also competent power management. Let's take a detailed look at each step so that your phone can effectively block unwanted calls.
Why Xiaomi is blocking third-party determinants
The Android operating system has a strict hierarchy of applications that handle phone calls. By default, priority is given to the system typer and built-in security services. On Xiaomi smartphones, this role is often performed by a bundle of Google’s Phone and MIUI’s Security. When you install Get Contact, the system sees it as a potential competitor who is trying to access sensitive data about incoming connections.
Without manual intervention, user settings can be reset after a system upgrade or memory cleanup. MIUI Optimization's aggressive power saving mode seeks to shut down any application that consumes resources in the background, even if it is necessary to instantly identify a number, which is why many users complain that the detector is unstable or stops showing tags after a device reboot.
⚠️ Note: When trying to make Get Contact the primary determinant, the system may issue warnings about a potential security threat. This is a standard Android response to system priorities, and in the case of proven apps from the Play Market, such warnings can be ignored.
In addition, recent versions of HyperOS have strengthened privacy protection protocols that require the user’s explicit permission to use the caller ID on each individual application.If you don’t grant advanced permissions, Get Contact will only work as a directory, but will not be able to intercept an incoming call before you pick up the phone.
Basic setting of access rights in MIUI and HyperOS
The first step to getting Get Contact to start identifying numbers correctly is to give it all the permissions it needs. Without that, the app will not be able to physically analyze the incoming data stream. Go to your smartphone settings and find the Apps → All Apps section. Go to Get Contact and go to the App Permissions menu.
You need to activate access to your phone, contacts, and microphone, and you need to pay special attention to Display on top of other applications, which allows the detector interface to be superimposed on the lock screen or the incoming call window. Without that permission, you'll see a standard call screen, and only after you answer or drop out will information from the Get Contact database appear, which reduces the effectiveness of the application to zero.
- 📞 Phone Resolution – allows the application to see the incoming call number and compare it to the database.
- 👥 Contact permission – necessary to sync your phone book with user tags.
- 🖥️ «Displaying on top of other apps" - critical for the function of the determinant pop-up window during a call.
- 🔔 Notifications – should be enabled so you can see blocking statistics and new tags.
Also, in the permissions menu, find AutoRun and activate it, which will allow the application to run with the system and be ready to work immediately after the screen is turned on. On Xiaomi devices with the new HyperOS shell, this item can be called “Run in the background” or be located in a separate submenu of special features.
☑️ Verification of basic permits
How to Assign Get Contact as Default Determinant
The most important step is to force the application to be assigned to the master identity handler. Unlike the default browser, there is no single "Make Principal" button, so you have to act through the call settings. Open the standard Phone app (green handset), click three dots in the corner, and select Settings.
In the settings menu, look for Caller ID & Spam. In this menu, you'll see a list of available services. If Google Number Settings is activated, turn it off. The system can suggest you choose an alternative, choose Get Contact. If the switch is inactive, try the next method through system settings.
Go to Settings → Applications → App Configure → Access to Special Features. Find in the Get Contact list and make sure the slider is active. Some versions of MIUI also require you to go to Settings → Passwords and Security → Privacy → Special Permits → Access to caller identification and select the desired application from the list.
⚠️ Warning: If after selecting Get Contact as the primary determinant, the standard call interface has disappeared or strange artifacts, return the default settings to the Default Apps menu and restart the device. System libraries conflict occurs on older versions of Android.
Once these steps are done, the system will prioritize the Get Contact database when the signal arrives, but in order to be stable, the application must be removed from the energy saving lists, as discussed in the next section.
Configuring energy saving for stable operation
Xiaomi smartphones are notorious for their rigid memory management policies: If an app is not active on the screen, the system tends to put it to sleep or shut it down completely to save battery life. For a number detector that has to run 24/7 in the background, it's lethal. To prevent Get Contact from closing, you need to change its power consumption profile.
Go to Settings → Battery and Performance (or simply Battery). Find the Get Contact app in the list. Click Activity Control and select No Limits mode. This will prevent the system from forcibly stopping the application processes even if the phone screen is off for several hours.
- 🔋 No Limits mode – allows the application to work in the background without time limits.
- 🚫 Auto-Start – ensures the start of service immediately after the phone is turned on.
- 📶 Network access – Allow Wi-Fi and mobile data to be used in the background to update the database.
Additionally, it is recommended to fix the application in memory. Open the list of running applications (swipe from the bottom up and hold or menu button), find the Get Contact window and click on the lock. This will prevent it from being cleaned when using the Clean All function.
What if the phone kills the process?
Conflicts with other security services
A common cause of instability is the simultaneous activation of multiple determinants. For example, you may have Yandex, Kaspersky and Get Contact installed. Android does not know how to properly handle incoming calls through three different applications at once, which leads to delays in the appearance of the call screen, double beeps or a complete lack of response to a call.
You need to select one main application to determine the number. If you prefer the Get Contact database, then in the settings of other applications, find the sections associated with the determinant and turn off their call interception function, leave them only the blacklisting function, if possible, or remove unnecessary applications.
| Annex | Determinant status | Recommendation | Impact on the battery |
|---|---|---|---|
| Get Contact | Active (Major) | Leave it on. | Average. |
| Google Definition | Unplugged. | Turn off in the phone settings | Low. |
| MIUI Antispam | Partly active. | Use only as a blocker | Low. |
| Third-party (Yandex, etc.) | Unplugged. | Recommended removal | High. |
It's also worth checking the settings of Xiaomi's built-in security antivirus. Sometimes it flags modified versions of the determinants as a threat. Add Get Contact to the scan exceptions so the system doesn't block its database files.
💡
Tip: Check the app updates on Google Play periodically (once a month). Developers often release patches that improve compatibility with new versions of Android and fix display bugs on high-frequency screens.
Frequent problems and ways to fix them
Even after setting up correctly, users may encounter problems, such as an app that works but doesn’t show a photo of the caller or tags that are updated late, often due to a lack of RAM on the device. On smartphones with 4GB of RAM or less, the system can aggressively unload “heavy” applications from memory.
Another common problem is that there is no Internet connection at the time of the call. Get Contact works in real time, checking the number through the server. If you have a bad 3G/LTE signal at the time of the incoming call, the application will not have time to download the information, in which case only the preload of contacts or waiting for communication to improve will help.
If the number screen doesn’t show up but the call is coming, check the permissions to display notifications. On Android 13 and above, you need to give a separate permission for each type of notification (incoming, missed, tags) to go to Settings → Notifications → Get Contact and make sure all categories are enabled.
💡
The key to stability: The combination of No Limits mode in the battery + memory fix + resolution "Master on top of other applications" guarantees the detector in 99% of cases on Xiaomi.
