When a message appears on a smartphone screen, “There’s been an error in the Gmail app,” it can take anyone on Xiaomi devices by surprise, and it can happen at the most inopportune moment, whether during an important correspondence or when you try to quickly check your workbox, usually a software conflict, a crowded cache, or a temporary failure of Google Play services.
Xiaomi, Redmi and POCO smartphone owners are facing this more often because of the aggressive optimization of MIUI, which can force the completion of background processes. System failure does not always mean a device breakage. In most cases, the situation can be corrected on its own in a few minutes without contacting the service center.
Below we will discuss all possible causes of the error in detail and provide step-by-step instructions for their elimination. The main cause of 90% of errors is a crowded cache or de-synchronization of Google account after the MIUI update. It is important to act consistently, starting with the simplest methods to avoid losing data.
Primary diagnostics and Internet connection check
Before you go into deep system settings, you need to make sure that the connection is stable. Gmail is extremely sensitive to network breaks, and it is a bad signal that often provokes a critical error message. An unstable Internet can interrupt the process of synchronizing emails, which the system perceives as a malfunction of the program.
Try switching between Wi-Fi and mobile Internet. Sometimes the provider blocks certain ports that are necessary for Google services to work, and it is also worth checking whether Flight mode, which may have been activated accidentally, is turned on.
- 📶 Check the signal indicators at the top of the screen for exclamation points.
- 🔄 Switch from Wi-Fi to Wi-Fi 4G/LTE And try to update the email feed.
- 🌐 Open any website in your browser to make sure you have access to the network.
If the Internet works consistently in other applications, such as YouTube or the browser, then the problem is localized in the email client, in which case we move to more detailed diagnostic methods.
Cleaning up the cache and data of the Gmail application
The most effective way to eliminate software glitches is to clean up temporary files.Cash accumulates information for quick downloads, but over time, errors can occur in it that block normal operation.Cache cleaning is a safe procedure that will not delete your emails, since they are stored on a Google server.
To do this, you need to go to the settings menu on the MIUI or HyperOS shell, find the Apps section and select All Apps. In the list, find Gmail and click on it.
☑️ Checklist for data cleanup
In the memory management menu that opens, you'll see two buttons. Click "Clear Cache." If that doesn't work, you can try the "Clear All" (or "Clear Data") button. Attention: the second option will reset the settings of the application itself, but it won't delete emails from the server.
💡
Once the data is cleaned, Gmail can run a little slower on its first run until it re-forms the cache base, which is normal system behavior.
Check date, time and synchronization
A critical parameter for secure SSL/TLS connections is the correct system time. If the date or time on your Xiaomi is downed, Google servers will refuse to establish the connection, giving an error of login or application operation.
Go to your smartphone settings and find the "Advanced" or "Advanced Settings" section. Select "Date and time." Make sure the "Use Network Time" switch is activated. If it's already on, try turning it off, setting the time manually, and then turning on automatic sync again.
⚠️ Warning: If time is constantly strayed after turning off the phone, this may indicate wear on the internal battery CMOS or a system failure of the motherboard that requires repair.
Also worth checking is the account sync status. Go to Settings → Accounts and Sync → Google. Make sure there is a sync check in front of your inbox. If the red exclamation point is on, click on it and re-enter the password.
Updating and reinstalling Google components
Gmail doesn’t work in isolation; it’s closely linked to Google Play services. If these components are outdated or damaged, email will stop functioning. On Xiaomi devices, updates often get stuck in line due to background activity limitations.
Open the Google Play Store app, click on the profile icon and select “Manage Apps and Device.” In the “Update available” section, check for updates for Gmail and Google Play Services. If no updates are found, it may be worth removing updates to Gmail itself.
To do this, in the app settings (the same place where the cache was cleared), click the three dots in the upper right corner and select "Delete Updates." After that, the phone will return to the factory version of the mailbox. Then start the Play Store again and update the application to the latest version.
| Component | Action. | Risk of data loss |
|---|---|---|
| Gmail (Annex) | Cache cleanup/Update | No. |
| Google Play Services | Only updates. | No. |
| Google Play Store | Clearing the cache | No. |
| Google account | Deletion and addition | No (data in the cloud) |
What to do if the Play Store is not updated?
Conflict of extensions and third-party additions
Users who use modified versions of Gmail or install third-party plugins to sort emails may encounter incompatibility. After another MIUI update, older extensions may no longer interact correctly with Android security.
Check the list of installed apps. If you've recently installed any accelerators, antiviruses, or task managers, try temporarily disabling them. Xiaomi's aggressive energy-saving algorithms often block email services as malicious activity.
- 🛡️ Turn off the "Energy Saving" mode in the notification curtain.
- 🚫 Remove newly installed applications that affect the network.
- 🔒 Check if Gmail is in the “Limitations” list in your battery settings.
It's also worth making sure that the device doesn't have unofficial firmware builds installed unless you're an experienced user. ROM-You may have conflicts with Google certification, causing persistent login errors.
💡
The “No Limits” power saving mode for Gmail significantly reduces the likelihood of background crashes and email loss.
Radical measures: dumping and alternatives
If none of the above methods worked, you might have damaged your system files or your user profile, in which case you might try to delete your Google account completely from your phone and add it back, and that will restart all sync services.
Go to Settings → Accounts and Sync. Select your Google account, click Delete Account. After rebooting your device, add it again. Full re-registration often eliminates deep errors in access tokens.
As a last resort, if the error persists, it makes sense to consider alternative email clients: apps like Microsoft Outlook, Spark or the standard MIUI Mail client work steadily and allow you to add a Gmail account without using an official application.
⚠️ Before deleting your Google account, make sure you remember your password, otherwise access to your device and data may be lost forever.
Sometimes it helps only a complete reset of the phone settings, but this should be resorted to last, having previously saved all the important data to a cloud drive or computer.
