Xiaomi Redmi 8 Pro – a popular smartphone with support for technology NFC, It allows you to use the device for contactless payments, data transfer and work with smart devices. NFC stops working for no apparent reason: the module does not turn on, does not recognize the tags or gives an error "NFC-In this article, we will look at all possible causes, from software failures to hardware breakdowns, and give step-by-step instructions for diagnosis and repair.
The Redmi 8 Pro (codename begonia) is a unique feature of the Redmi 8 Pro. NFC-The module is integrated into the wireless charging antenna, making it vulnerable to mechanical damage, and problems can arise from incorrect updates. MIUI, Firmware conflicts or even banal contamination of contacts. We analyzed user reviews on forums. 4PDA, Mi Community and Service Centers to Collect Relevant Solutions for 2026.
1. Check the basic NFC settings
Before you commit to hardware malfunctions, make sure that the problem is not in the settings or software conflicts that are disabled. On Redmi 8 Pro, NFC is managed via the Settings menu → Connections and Exchange → NFC. If this item is missing, then the module is disabled at the system level.
What to do:
- 🔍 Check if it's on. NFC In the notification curtain (quick settings) sometimes it shuts down after you reboot.
- 📱 Go to Settings. → Annexes → Application management → NFC Make sure that the service is not forcibly disabled.
- 🔄 Reboot the smartphone – it will reset temporary errors in the module.
- 🛡️ Turn off the power saving mode (in Settings) → Battery) as it can block background work NFC.
Important! On some MIUI firmware, the NFC may be called Contactless Payments or Mi Pay. If you don't find a partition, try searching by settings (the magnifier icon at the top of the screen).
2. Conflicts with firmware and MIUI updates
One of the most common reasons for the NFC not working on the Redmi 8 Pro is the unstable MIUI updates. Users often complain that after installing a new firmware version (especially MIUI 12.5 and higher), the module stops recognizing tags or disappears from settings altogether, due to driver errors or conflicts with Google Pay services.
How to diagnose:
- 📲 Check the version. MIUI In Settings → The phone. → Version. MIUI. If it is a beta (marked with a letter "V" or "Beta"), there is a high probability of bugs.
- 🔧 Open the Settings. → Annexes → Application management → Google Play Services and Clear Cache.
- 🛠️ Install manual updates through Settings → The phone. → Update the system by selecting a stable version.
If the problem has occurred after the update, try to retrace the previous version of MIUI via Fastboot or Recovery.
- Download the official firmware for begonia (Redmi 8 Pro).
- Go to Recovery (clip Power + Volume up when the phone is off).
- Select Install update.zip and specify the path to the downloaded file.

⚠️ Attention! Firmware rollback erases user data. Pre-backup through Settings → Additionally. → Backup and reset.
3. Hardware malfunctions: antenna and NFC chip
If software methods fail, the problem may lie in physical damage. NFC-The Redmi 8 Pro has an antenna. NFC It's located under the back cover next to the coil of wireless charging, and it's vulnerable to:
- 💥 Hits or falls (especially at the corner next to the camera).
- 💧 Moisture infestation (even if the smartphone does not sink, condensate can oxidize the contacts).
- 🔌 Incorrect replacement of the battery or back cover (damage to the plume).
How to check:
- Remove the back cover (requires a mediator and a hair dryer to soften the glue).
- Look at the flexible NFC plume, which goes from the motherboard to the antenna under the camera.
- Check the antenna contacts for oxidation (green plaque) or cliffs.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| NFC is not turned on, in the settings gray slider | A plume break or chip dump | Replacement of the plume or soldering of the chip (sweeter station required) |
| The module is switched on but does not read the tags. | Antenna damage or metal shielding | Replacement of antenna or removal of metal stickers |
| Mistake "NFC-chips not found" | Short circuit or overheating of the chip | Diagnosis with a multimeter, replacement of the module |
| It only works after the reboot. | Bad plume contact | Reconnecting the plume or replacing it |
⚠️ If you don't have experience in dismantling smartphones, don't try to repair them. NFC Damage to the wireless charging plume can result in complete loss of function!
4. Conflicts with applications and services
NFC on Redmi 8 Pro can be blocked by third-party apps, especially if they request access to contactless payments or device management.
- 💳 Applications of banks (SberBank Online, Tinkoff, Alpha-Click).
- 🔐 Password managers (1Password, KeePass).
- 🛡️ Antiviruses (Avast, Kaspersky, 360 Security).
- 🎮 Emulators (e.g., emulators, NFC Tools or Trigger).
How to resolve conflict:
Turn off all banking apps in the background|Clear the cache of Google Play Services|Remove unused items NFC-applications|Check the permits for Mi Pay
-->
If the problem occurs after installing a new application:
- Go to Settings → Applications → Permissions → Other permissions → NFC.
- Revoke access to suspicious programs.
- Restart your phone and check the NFC.
Tip: Use Safe Mode to check. Press the power button → hold off “Stop” → confirm the transition to Safe Mode. If the NFC is up, one of the installed apps is to blame.
5. NFC reset and calibration
Sometimes NFC stops working because of a calibration failure, which can happen after a fall, battery change, or firmware update, and in these cases, resetting the module through the engineering menu helps.
Instructions:
- Open the phone app and enter the code: ##4636##
- Go to the phone information section.
- Scroll down to the NFC block and press Reset Settings.
- Confirm the action and restart the smartphone.
If the engineering menu is not available, try an alternative method:
- Remove all contactless cards saved in Google Pay or Mi Pay.
- Turn off the NFC in the settings.
- Clear the NFC application data in Settings → Apps.
- Turn on NFC again and perform the initial setup.
⚠️ Attention, reset NFC You can use the engineering menu to lose your associated bank cards.
6.Problems with SIM-map and mobile
Few people know, but the Redmi 8 Pro is a work in progress. NFC may depend on SIM-The fact is that some operators (for example, MTS or Beeline) block contactless payments through the Internet. HCE (Host Card Emulation is a technology that emulates a bank card right in your phone. SIM-Old card (released before 2018), it may conflict with NFC.
How to check:
- 📶 Check if your tariff supports NFC-Payments (check with the operator).
- 🔄 Try inserting another one. SIM-map (preferably a new model with support) 4G VoLTE).
- 📱 Update profile SIM-map USSD-team (e.g. for MTS: *111*1234#).
If the problem is SIM-The map will show the following symptoms:
- NFC is included but cannot initialize payment.
- The bank’s application gives an error “I was unable to connect to the payment service”.
- In the system logs (viewed through ADB) bugs HCE_ERROR.
💡
If you use two of them SIM-If you want to leave one card, try to leave one (in slot 1). NFC conflict with the second communication module.
7. When there's only a service center left
If all of the above methods have not worked, the problem is likely hardware in nature, in which case you will need professional diagnosis.
- 🔧 NFC It does not turn on even after resetting the settings.
- 📡 The wireless charging antenna also doesn’t work (the phone doesn’t charge from Qi charging).
- 🔥 The phone overheats in the upper part of the body (possibly a short circuit in the module). NFC).
- 🛠️ In the system logs (through ADB NfcService: Chip not responding.
The cost of repairing NFC on Redmi 8 Pro in service centers:
| Type of repair | Cost (₽) | Time (hours) |
|---|---|---|
| Replacement of the plume NFC/wireless | 1 200 — 1 800 | 1–2 |
| Solding/replacement of NFC chip | 2 500 — 4 000 | 2–3 |
| Replacement of NFC antenna | 800 — 1 500 | 1 |
| Diagnosis + cleaning of contacts | 500 — 1 000 | 0.5–1 |
⚠️ If you're offered a full replacement motherboard because of a non-working motherboard NFC — It's a scam. NFC Redmi 8 Pro is replaced separately.
💡
Before visiting the service center, back up your data via Mi Cloud or locally on your PC. NFC repairs may require a complete phone reset.
