Activate in-app purchases in Brawl Stars on Xiaomi

The mobile industry continues to grow at a rapid pace, and modern smartphones like Xiaomi devices offer users an incredibly powerful hardware to run demanding games. However, even owners of top models often face technical nuances when trying to make a purchase in the app, especially if it is a popular shooter Brawl Stars.

For owners of Redmi and Poco smartphones, the payment activation process requires a series of steps that can seem confusing without clear guidance. MIUI or HyperOS security can block transactions if the application does not have the necessary permissions or if the Google Play account is not tied to the current region. In this article, we will detail each step necessary to ensure that your gaming balance is replenished without undue difficulties.

Don't panic if the purchase button doesn't respond or if an error crashes, which is a standard situation for the Android ecosystem in the current environment. We'll look at not only standard solutions, but also specific workarounds that are often overlooked by ordinary users.

Checking Google Play and Account Settings

The first and most important step is to verify the main source of purchases – the Google Play store. It is through it that 99% of all transactions in Android games occur, and any errors in its work block the ability to buy Gems or Brawl Pass.

Often users forget that they may have multiple profiles and the Brawl Stars app tries to use the default not the one they want. Go to the phone's settings, find the "Accounts" section and check sync. If you see a status "Sync Error" next to your Google account, this could be the reason for blocking purchases.

• 🔍 Open the Google Play app and click on the profile icon in the upper right corner.
• 🔄 Select Settings and make sure that the General section selects the correct country and currency.
• 💳 Go to Payments and Subscriptions to check the status of the linked card.
• 📱 Make sure the version of the Google Play app is up to date – older versions may not support new security protocols.

It is important to understand that the region of your account must match the region you specified when you created your payment profile, and if you recently moved or use a VPN, the system may consider this as suspicious activity and temporarily freeze your purchases, which will require waiting or contacting Google support.

Configure permissions and link Supercell ID

Transaction security in modern operating systems comes first, so HyperOS and MIUI have strict rules about which applications can interact with payment systems. To work properly, Brawl Stars needs to give it full network access and, in some cases, permission to display on top of other windows so that the payment window can open on top of the game.

Supercell binding ID This is a critical step that many people ignore, relying on guest login or login through Google Play Games. ID ensures that your purchases are saved even when you change your device or reinstall the game. ID Recovery of purchased items may be impossible.

To set up the necessary permissions, go to Settings → Apps → All apps. Go to Brawl Stars and select Permissions. Here you are interested in Internet access (Wi-Fi and mobile data) that should be enabled. It is also worth checking whether the traffic saving mode for this application is activated, since it can block the connection to the payment server.

⚠️ Warning: Do not give the app unnecessary permissions, such as access to contacts or microphone, if the game does not require them.This can create security vulnerabilities in your device, although this is not a prerequisite for payment.

After checking the permissions, make sure that your Supercell ID is displayed in the game itself. If it is a Guest or a connection error is displayed, the transaction will not pass. Press the Connection button in the game settings and follow the instructions on the screen to log in or sign up.

Memory management and cache cleaning

The accumulated garbage in the system is one of the most frequent causes of unstable applications on Xiaomi smartphones. The cache of Google Play Services and the app store itself can grow to hundreds of megabytes, containing outdated data that conflicts with new payment requests. Regular cleaning of this data helps to shake up the system and establish communication with servers.

The cleanup process is safe for your personal data, as it only deletes temporary files, not logins or passwords. However, you should be careful when choosing options: do not confuse Clear cache with Clear all data, although in the case of Google Play, re-entering your account will solve the problem.

To do the cleaning, go to Settings → Apps → App Management. In the list, find the Google Play Store, click Storage and select Clear Cache. Then repeat the procedure for Google Play Services. After that, it is recommended to restart the device so that the system will reinitialize the services.

Solving Regions and VPN Problems

Use of virtual private networks (VPN) The new rules have become the norm for many gamers who want to access regional versions of games or servers with less ping, but the security systems of payment gateways of Google and banking organizations are extremely negatively reacting to the sudden change in the game. IP-address, especially if it belongs to another country.

VPN before entering the game and making a purchase.

There are also content restrictions depending on the region: Some items or events in Brawl Stars may only be available in certain countries, and trying to buy them with an account from another region will result in an error.

• 🌍 Turn it off. VPN-service before launching the game and app store.
• 📍 Make sure that the Google Play settings indicate the country of your current stay.
• 💳 Check if your bank supports transactions in the currency listed in the store.
• 🔒 If you change your country of residence, remember that you can only change your region on Google Play once every 12 months.

⚠️ Attention: Frequently changing regions in your Google Play profile can result in a complete blocking of your ability to make purchases on your account.

Alternative payment methods and cards

With the changing working conditions of international payment systems, users in a number of countries may face the inability to pay directly from Visa or Mastercard cards issued by local banks, in which case alternative methods come to the rescue, which allow you to convert funds and pay for content to Google Play.

One of the most popular ways is to use virtual cards or mobile carrier balances, if supported, and many players resort to buying Google Play top-up codes that can be activated in the app and used for internal purchases.

The process of activating the code is simple: open Google Play, click on the profile avatar, select Payments and Subscriptions → Use the code. Enter the code and the amount will be credited to the account2unt balance. This is the most reliable way, since it does not require you to link the card directly to the store.

💡

When buying Google Play codes, pay attention to the code currency. Dollar or euro codes may not be activated on accounts registered in rubles or tenge without changing the region, which is not recommended often.

Also consider linking a mobile phone account if your carrier provides such a service, and in Google Play payment profile settings, select Add Payment Method and find your carrier, which will allow you to charge purchases directly from your SIM card balance.

Frequent errors and their elimination

Even if you follow all the instructions, users can encounter specific error codes that are confusing. Understanding the nature of these errors helps you find a solution faster and avoid wasting time on useless actions. Most problems are software-based and solved by restarting services.

The “DF-DFERH-01” error usually indicates connection problems to Google Play servers. The solution lies in clearing the cache (as described above) and checking the stability of the Internet connection. The “504” error indicates an application version conflict or device incompatibility, which is solved by updating the system and application.

If the money is written off but Gems hasn't arrived, in no case try to re-purchase immediately.This can lead to a double charge. Wait 24 hours, check your Google Play transaction history (Settings → Payments & Subscriptions → Budget and Order History). If you have a transaction but no product, contact Supercell through the game settings, providing a screenshot of the check.

💡

The main rule for payment errors is to remain calm and not to make repeated attempts to pay during the day to avoid blocking the account by the bank for suspicious activity.
