Why the screen is hanging on Xiaomi: a complete guide to elimination

The situation when suddenly freezes the image on the display of a smartphone, familiar to many owners of devices Xiaomi, Redmi and Poco. the User may face complete disregard of touch or partial responsiveness of individual areas of the screen. Most often the problem lies in a software conflict or overflow of RAM, which causes the processor to not cope with the rendering of the interface.

But don't panic and bring it to the service center, and in most cases, you can fix it yourself if you understand the nature of the failure, and system errors in the MIUI or HyperOS shell are often the root cause, especially after a failed update.

It’s important to distinguish between software “freeze” when your phone is still in the background and a full “hardlock” that requires a forced reboot, and understanding this difference will help you choose the right algorithm to restore your Android smartphone to work.

The main reasons for the freeze of the interface and touch screen

The first thing you need to do is analyze what preceded the problem, and if the screen freezes after you install a new app, you have a 90 percent chance of finding the culprit, and incompatible software can cause resource conflicts by blocking the touch layer.

Also, it's often caused by overheating, and when the CPU temperature reaches critical temperatures, the system automatically lowers the clock speed or completely stops the processes to protect the hardware, at which point the screen may stop responding to commands.

The physical condition of the display should not be discounted, as cracks, extreme temperature changes or moisture can damage the digitizer. Unlike software failures, it will require a replacement of the touch module, since software methods will be powerless.

Another factor is system partition overflow: If the internal storage space is less than 1 GB, the operating system does not have a buffer for temporary files, which leads to hangings.

• 🔋 Critically low battery charge and voltage surges.
• 💾 Damage to system files after interrupted update.

Use Safe Mode to check, and if the screen isn't hanging, it's a third-party app that's the problem.

Quick methods to eliminate freezes without data loss

If the screen is frozen, but the phone continues to give signs of life (vibration, notification sound), try a software reboot. On many Xiaomi models, this is done by holding the power button for a long time for 10-15 seconds.

In cases where the touchscreen is partially responsive but the menu is not available, you can try calling the switch-off menu with a combination of buttons. Press Volume Up + Power at the same time. This often helps to get out of the dead loop state without resetting the data.

If you lose access to the system completely and the screen is black or static, the "discharge" method will help. Leave the phone with the screen on until the battery is completely exhausted. Then put it on charge and try to turn it on.

⚠️ Warning: Do not attempt to disassemble the case of the smartphone if it is under warranty.Opening the back cover automatically voids the manufacturer's warranty obligations.

Often, cleaning the cache of the apps that consume the most resources helps. Go to Settings → Applications → All applications and find heavy programs. Click on them, select Clear cache (do not confuse with Clear all so you do not lose logins).

Diagnostics through the Engineering Menu and Recovery

For deep screen and sensor diagnostics, MIUI has a special engineering menu, so to get there, open the Phone app and enter the code ##6484##.

In the CIT menu that opens, select the item associated with the display check (usually called "Touch" or "Display"). Follow the instructions on the screen, drawing lines through specific zones, which will reveal "dead" areas of the touchscreen.

If the tests in the engineering menu are successful, but the screen freezes in normal operation, the problem is software-based, in which case you should try resetting to the factory settings through the Recovery menu, but saving important data beforehand.

Problems after firmware updates and their solution

Updating the operating system is always a risk, and even official HyperOS or MIUI builds can contain bugs that cause unstable touchscreen performance on specific motherboard models.

If the freezes started immediately after the update, the first step should be to clean the Dalvik/ART cache. This will not delete your photos or contacts, but reassemble system files again, eliminating conflicts of old settings with the new version of Android.

In some cases, rolling back on the previous firmware helps, but this process is more complicated and requires a computer and a Mi Flash Tool. Be careful: when you roll back, data is most often deleted completely.

• 🔄 Check the update history in your model’s user community.
• 📉 Recoil is only possible on the version below the current one, but above the minimum supported version.
• 💻 A cable is needed to reflash USB 3.0 and a serviceable port.

💡

Stable ROMs contain fewer bugs than beta ROMs, but are updated less frequently.

Hardware malfunctions: when repairs are needed

If the software methods don't help, and the screen keeps hanging or "glutching" at random moments, it's probably the hardware. A common problem with the budget and mid-range Redmi models is the detachment of the display plume.

This can be due to falls, vibrations, or simply poor build, symptoms: the screen goes out or freezes when you press certain points of the body, or the image begins to ripple before hanging.

⚠️ Warning: If the phone falls into the water, even in small quantities, the contact oxidation can occur gradually.

It's also worth checking the power button. If it's locked or locked, the phone may be constantly trying to go to sleep or lock the screen, try to carefully (without fanaticism) develop the button or clean it with alcohol.

If the power controller or the display module itself fails, only replacing components in the service center will help. Self-repair is possible, but requires skills with a soldering iron and thin electronics.

Prevention of freezes and optimization of the system

To avoid a repeat of this, you need to regularly service your smartphone. Don't let the memory fill up. Android requires at least 10-15% free space for the normal operation of the paging files.

Use only certified chargers. Cheap power supplies can produce unstable voltages, causing chaotic touchscreen behavior and getting stuck while charging.

Turn off animations in the Developer menu. This will not only speed up the visual interface, but also reduce the load on the GPU, reducing the likelihood of lag on older models.

Check your running list regularly. Some programs can hang in the background, consuming resources. Use Xiaomi's built-in security optimizer to clean up your memory.
