Security Patch and Performance Enhancements

The key to any phone experience is security. The update comes with the new security patch, based on MIUI, which concerns the vulnerabilities that may expose your information to risk. And unless you want to languish in the dungeons of the local black-hat site (who does?) it pays to remain up to date in this area.

On its performance side, it has a bundle of system enhancements. What that entails is less stuttering, more dependable app loading, and reduction of that slowness you occasionally get as you navigate about the phone.

Here’s a snapshot of performance improvements:

  • Up to date MIUI security patch, threats under control.
  • Optimations of the system in case of reduced lag and navigation.
  • Improved user experience such that the phone is faster and reliable.

These improvements imply that you will not wait so long until applications open, but use your phone.

Fixes and Improvements in Phone Functionality

The essence of this update dwells in the repair of the actual problems people complained about and the optimization of the things you use daily. I will discuss all important spheres which have been enhanced.

1. Language Translation Accuracy

Provided you have been experiencing some pains related to the language translation bugs, namely problems with UI texts or settings that did not reflect the appropriate translations, this fix should take care of that. It is also evident in the translation engine that the text has been displayed in a more accurate and clear manner in the system menus.

2. Power Button Responsiveness

In the previous versions, some users observed that power button ceased responding to press-and-hold. The mechanical switch was functional, but the bugs in the system could make one action such as locking or restarting unstable. That problem is solved. The power button is responsive appropriately, in both press and press and hold.

3. Battery Optimization and Drain Fixes

Some people were left with drained batteries when their phone was not in use or unusually fast battery percentages because of older versions of the software. Unexpected drain and battery backup optimization are smoothed by the new update. Each cycle will offer a more reliable longer lasting charge.

4. Navigation Button Display Fixes

Have you ever pressed the navigation buttons only that they do not appear or respond as they should? That bug was a hindrance to phone usage and disrupted muscle memory. Through this update, the buttons used to navigate now show correctly and permanently in every part of the device, this way it is now easy to maneuver around the gadget.

5. App Responsiveness and Speed

Some programs were not starting up with the smooth speed or were not shutting down easily. There is no longer that lag. When launching an app or closing it, it gets immediate results, resulting in a more fluid process of browsing, messaging or multitasking.

6. Overheating During Gaming & Heavy Usage

The phone was taking time to warm up when running heavy games or applications. That has been streamlined. The update reduces the tendency to overheat when gaming and when multitasking heavily, respectively, and, thus, the chances of experiencing a lag or forced app closure.

Concise improvements addressed here:

  • Correct use of words in menus and places On the one hand, they call it menu, on the contrary, menu in Russian. On the one hand, it is setting, on the contrary, setting in the Russian language.
  • it is possible that the power button is functional now
  • Improved battery back up, idle drain corrected
  • Navigation controls show and operate well
  • Applications open and shut quicker
  • It will not overheat as much with games and heavy applications

Camera and Video Recording Improvements

This update gives a rise to photo and video lovers. The camera system is also improved to have an enhanced image quality and reliability during stills and video.

  • De-noise of Photo
  • Before the update, photos, particularly in low light, used to have a lot of grain in it. Noise has been minimized and it has brought clear and more crisper shots now.
  • better Camera Settings
  • The revise under the hood adjusting the camera settings provides you with more natural color, a better balance of brightness and focus that is more accurate.
  • Better Video recording
  • There are no more lags or dropped frames as the video recorder works as expected. Bugs that created dinosaurian-like choppy footage or even out-of-sync audio have been sorted out.

You might also find that photos are crisper and a video experience is simpler and more dependable whether you use it to take a few quick shots or capture video more than 10 seconds. It will be a good change when it comes to uploading on social media and storing memories.

Network Connectivity and Call Quality Enhancements

Nothing can be more frustrating than call drops or poor connectivity, when you need to call someone. This update makes network stability more stringent and call quality as a whole.

  • Better Network Connectivity Relations
  • There is a reduction in number of network losses and unstable signals. Connections are managed much better in the software, and as a result, streaming, browsing and updating of applications experience fewer interruptions.
  • Better Quality of Calls
  • The voice calls are heard clearer and the drops are less in locations where the signal is low. The clarity of audio and its reliability gains improvement.

These changes have made phone calls more stable and daily networking through scrolling, downloading process more reliable.

User Interface (UI) and Visual Enhancements

The amount of fun you get with your phone boils down to visuals and customizations. This refresh has improvement and new features that are enjoyable.

Fixes on Home Screen, Lock Screen, and Wallpapers

I used to encounter issues when some actions were not published correctly on-screen, such as app icons or wallpapers. Sometimes I had a glitch in icons or some wallpapers would appear strange on specific screens. The bug regarding those icon and display bugs is fixed in the update. The home screen, the screen lock, and application icons are now also smooth across the board.

UI Color and Monochrome Icon Improvements

Certain third-party programs would not get along with some of the pre-installed color schemes and system user interface palettes. Those are problems that are addressed now. Regardless of whether you are using preset colors, dark mode, or particular icon styles, everything still shows with uniformity even among the apps that you add outside the Play Store.

  • More control of third party app UI color options.
  • Glitches were fixed about mono icons or colors not popping up anymore.

New Wallpapers and Customization Options

Personalization received a certain stimulus as well. The update enables one to customize the home and lock screen wallpaper further, along with a set of new wallpapers. A convenient magic photo removal tool also allows you to edit or modify your photos to something better, then set them as wallpapers. It is fantastic when you need to get rid of the undesirable information fast or simply to clear up an image in order to use it as one of your wallpapers.

UI and visual changes:

  • Now the icons appear normally; the missing and strange images are gone.
  • New custom wallpapers, with simple possibilities to adjust or upgrade them.
  • Improved photo editing capabilities before they can be used as wallpapers.

Conclusion

All the people, who have an IQoo Z10 or a Vivo T4, need to update to the May 2025 version. It is particularly noteworthy in case you have observed the battery, button, camera, or UI problems on your phone. To owners of new devices, early application of such update would prevent minor headaches, which at times accompany new phones out of the box.
