Xiaomi’s current MIUI or HyperOS smartphones are powerful financial management tools, but integrating international payment systems often raises questions. PayPal’s setup on devices of this brand has its own peculiarities related to aggressive battery optimization and specific security permissions. Understanding these nuances will avoid situations where the application closes in the background or does not send transaction notifications.
The installation and initial configuration process requires careful attention to system settings, as the standard algorithm can be disrupted by built-in power saving mechanisms. It is critical to set up auto-start and permissions manually immediately after installing the application, otherwise payment notifications may come with a delay. In this article, we will detail each step, from downloading the current version of the software to solving common authorization errors.
Many Redmi and Poco owners have difficulty linking a bank card or verifying identity, not always due to service locks, often due to mis-defined region or time settings, and fine-tuning localization and network settings will help eliminate most technical hurdles.
Preparation of the device and downloading the application
The first step is to keep your device secure, as financial applications require a secure environment. Make sure your Xiaomi has a password or biometric protection set and Google Play Protect activated in the security settings. This is a basic layer of protection that prevents you from installing modified or malicious versions of programs.
Downloads are best done exclusively through the official Google Play Market store. APK-If you have a device that is released for the Chinese market, make sure that Google services are installed and work correctly, as PayPal is critically dependent on their functioning.
Once the installer is loaded, the system may request installation confirmation from unknown sources if you use alternative methods, but in the case of Play Market, this step is usually skipped.
☑️ Preparation of the smartphone for installation
Initial setting up and registration of the account
When you first run the app, you'll ask for permission to use geolocation and contacts, and you'll need permission to access geolocation for verification and fraud prevention, but you can choose "Only while using the app," which is a balance between functionality and privacy.
Registering a new account requires you to enter up-to-date personal data that must match the data in your bank. An error in spelling a name or address, even by a single letter, can lead to the blocking of the account by PayPal security service.
For existing users, the login process is standard, but it may require re-verification via SMS or email.The security system can recognize a new Android device as a suspicious device, so keep a phone tied to your account on hand to confirm the login.
Configure permits and energy saving in MIUI
This is the most important section for Xiaomi owners.The MIUI shell is known for its aggressive policy of closing background processes, which can result in you not getting a notification of receipt of funds.You need to manually change the battery settings for the PayPal app.
Go to Settings → Apps → All apps → PayPal. You need to find “Activity Control” or “Energy Saving” and select “No Limits” mode. The standard “Energy Saving” mode will kill the application process as soon as you turn off the smartphone screen.
You also need to activate AutoRun. In the same app settings menu, find the AutoRun switch and turn it on. Without this permission, the operating system will not allow the application to start the necessary services to receive push notifications after the device is restarted.
⚠️ Note: If you don’t set up “No Limits” mode for the battery, payment notifications may only come after manually opening the app, posing a risk of missing out on an important financial status.
Check notification settings further. Make sure that all categories are included in the Notifications section, especially Android Important Notifications and Floating Notifications, which ensures that the transaction message appears on the lock screen.
💡
Enable app lock in the App Protection menu so that access to PayPal requires a fingerprint or Face ID at each launch.
Bank card binding and verification
Payments must be linked to the card, Visa, Mastercard and in some Mir regions (through third-party gateways, if relevant) are supported, and enter the card details carefully: number, expiration date and CVV-code.
Once the data is entered, the issuing bank can request confirmation of the transaction via SMS or the bank’s application. This is standard 3-D Secure procedure. If the card is not tied, contact the bank, as some financial institutions block transactions with international payment systems by default.
PayPal can charge a small amount (about 1.95 USD/EUR) and send a code in the transaction description, which will need to be entered in the appropriate field in the application to confirm ownership of the card.
The following table shows the statuses of the cards and their meaning:
| Status of the map | Meaning | User actions |
|---|---|---|
| Confirmed. | The card is active and ready to pay | No action required |
| Waiting for confirmation. | Entering the code from the statement is required | Check the bank statement and enter the code |
| Overruled. | Bank or security system fails | Contact the bank or change the card |
| Iceglass | Card expires | Delete the map and add a new one |
Solving common mistakes and problems
One of the common problems is a connection error or "something went wrong." Often this is due to an unstable Internet connection or a server lock by the provider. Try switching from Wi-Fi to mobile Internet (4G/5G) or vice versa.
If the app crashes immediately after launch, try clearing the cache. Go to Settings → Apps → PayPal → Memory and click Clear Cache. Don't confuse it with Clear All Data, as this will require re-entering your account.
Also, the problem can be in the wrong time. Make sure that the settings in the Xiaomi "Date and time" check "Use network time." SSL.
What to do if the app says “Update the Android version”?
Security and Two-Factor Authentication
Financial security on a mobile device is impossible without enabling two-factor authentication (2FA). In PayPal's security settings, activate this option. Now, you will need a code from an SMS or an authenticator application to log in from a new device or make suspicious transactions.
Use the MIUI-built fingerprint scanner or Face ID for a quick but secure sign-in. The PayPal app settings also enable biometric protection, which adds another layer of security each time you run.
Check the active session list regularly in your account security settings. If you see a device you don't know about or a city you're not in, immediately terminate that session and change your password.
⚠️ Note: Never report codes from SMS PayPal emails to no one, even if the caller is a support employee, PayPal employees never ask for confirmation codes.
💡
The comprehensive setup of access rights and the inclusion of 2FA turn your smartphone into a secure financial instrument, minimizing the risks of fraud.
