Why is the screen turning on Xiaomi Redmi

Xiaomi and Redmi smartphone owners often experience a device interface that changes orientation for no apparent reason, such as when reading news, watching videos, or even locking a device, which is annoying because it interferes with normal use of the gadget and disrupts the usual scenario.

The problem can be both the trivial setup you might have forgotten about and the more complex hardware malfunctions, the gyroscope and the accelerometer are sensitive sensors that respond to the slightest change in the position of the housing in space, and sometimes they transmit incorrect data to the system, which leads to a misfolding of the image.

In this article, we will look at all the possible causes of this behavior of the MIUI or HyperOS operating system. You will learn how to conduct diagnostics with built-in tools when software calibration is required, and in which cases it is worth thinking about repairs. A common cause of chaotic turn is not a hardware failure, but a software conflict of background applications.

System settings and sensor operation

The first thing to check is the status of the orientation switch itself. In Xiaomi's shell, this setting is controlled by the notification curtain. If the Autoporot icon is active (lit in blue or orange), the system will automatically change orientation when you turn the device, but sometimes users forget to turn this feature off or turn it on accidentally.

You can swipe down the screen to check your current status. If you see a circular arrow lock icon, that's orientation control. In some versions of MIUI, the logic is inverted: if the orientation lock icon is on, the screen won't rotate, and if the icon isn't, it will. Carefully watch for the prompts that pop up when you press.

Also, you should pay attention to the special features settings. In the Settings menu β†’ Advanced Settings β†’ Special features there are gesture control functions. If you have the option to control the head rotation or tilt of the device for certain actions, this can cause an undesirable interface reaction.

Rarely, after a fall
Never noticed.

It's important to understand that an accelerometer is a device that detects acceleration, and it doesn't know where it's up and where it's down, it just senses gravity, and if you hold your phone at a 45-degree angle, the sensor can fluctuate between values, and the system will frantically try to determine which orientation to choose, whether it's portrait or landscape.

Software failures and application conflicts

One common cause of erratic screen behavior is third-party apps. Some programs, especially launchers, weather widgets, or window control utilities, can intercept sensor control. If you recently installed a new app and the problem appeared immediately afterward, it's worth checking its impact.

Also, Android malfunctions can cause sensor signals to be processed incorrectly, often after a failed update or when the system cache overflows, in which case the system can ignore the physical position of the phone and rotate the image randomly.

  • πŸ” Check the list of recently installed apps and remove suspicious utilities.
  • 🧹 Clear the system cache through the Security menu β†’ Cleanup.
  • πŸ”„ Restart the device in safe mode to eliminate the impact of third-party software.

If the problem is gone in Safe Mode, it means that one of the installed applications is to blame. You'll need an exclusion method to find culprit. Run apps one at a time and check the screen response. It's a tedious process, but it allows you to pinpoint the source of the conflict without resetting data.

How to get into Safe Mode on Xiaomi?
Press and hold the off button on the screen. When the turn off icon appears, press it and hold your finger until you have a message to go to safe mode. Confirm the action.

Need for calibration of the gyroscope

If the settings are fine, and the applications have nothing to do with the calibration of the sensors, and over time or after a fall, the gyroscope may start to give out the wrong coordinates, and the system thinks that the phone is horizontal, even though you hold it vertically, and accordingly changes orientation.

To diagnose and correct the situation in Xiaomi smartphones, there is a hidden engineering menu, accessed through the Phone app, you need to enter a special combination of characters that will open the hardware testing menu.

Done: 0 / 4

In the CIT menu that opens, you need to find a item associated with a gyroscope or touch screen. Follow the instructions on the screen: you usually need to put the phone on a perfectly flat horizontal surface and press the calibration button.

Once the procedure is complete, be sure to restart the device, which will allow the system to apply new correction factors, and if after calibration the screen is still behaving strangely, it may be that the sensor is physically damaged or the train has moved away.

Influence of protective accessories and covers

Massive protective covers, especially those with magnetic latches or metal inserts, can interfere with the operation of magnetic field sensors (magnetometers). Although the magnetometer is primarily responsible for the compass, its data is often used in conjunction with a gyroscope to determine position in space.

Try removing the cover and observing the behavior of the screen, and if the problem has disappeared, the accessory is not correctly selected, and also check if there is a protective film or glass on the screen that has been glued with a violation of technology, air bubbles or a thick layer of glue can create a voltage on the matrix, which is sometimes interpreted by the system as touching or changing geometry.

Thick tempered glassMediumCheck for bubbles

πŸ’‘

If you're using a magnetic mount in a car, don't put a metal plate at the top of your smartphone. This is where the main sensors and cameras are, and interference is most likely.

Hardware malfunctions and consequences of falls

The most serious cause is physical damage to components. If your Redmi recently fell or was subjected to severe vibration, the plume connecting the board to the sensor module could have departed. In modern smartphones, the accelerometer and gyroscope are often embedded directly into the motherboard or are on a separate small board connected by a plume.

The symptoms of hardware failure are not only spontaneous turning, but also other oddities: cursor "twitching," inability to calibrate the compass, strange behavior in games with tilt control, in which cases software methods are powerless.

⚠️ Warning: If the screen has started to live its own life after falling, don't try to disassemble the device yourself if you don't have experience.

Hardware problems are better diagnosed in a service center, where wizards use oscilloscopes and software to check sensor signals in real time, and replacing the module or soldering the plume will solve the problem if it is in the hardware.

Resetting and system update

When all methods are exhausted, the radical but effective step is to completely reset the settings to factory settings, which will delete all user data, applications and most importantly, reset all system configurations that may have been corrupted. Before the procedure, be sure to back up important data to the Mi Cloud cloud or to your computer.

You can reset via the Settings menu β†’ About Phone β†’ Settings reset β†’ Erase all data. Once turned on, the phone will be like new. If the problem persists due to a software glitch, it should disappear. Also check for system updates: Xiaomi engineers regularly release patches that fix sensor bugs.

πŸ’‘

Hard Reset eliminates 90% of software causes of sensor malfunction, but requires prior storage of user data.

Updating your firmware is a less radical method, but it also often helps. Go to Settings β†’ About your phone and click on the MIUI version. If a new update is available, install it. Changelogs often write "Improved system stability" or "Fixed sensor issues," which is directly related to our problem.

Why does the screen only turn in certain applications?
This is normal behavior if the settings of the app itself (for example, YouTube or Gallery) allow autorotation, and others (for example, in the launcher) do not. Each application has its own manifest, which spells out the allowed orientations of the screen.
Can a discharged battery affect the operation of the gyroscope?
Very rarely, but at critically low charge and unstable voltage, some sensors may not work properly, but more often than not, the phone will simply turn off before you notice the strange turn of the screen due to discharge.
How do you know exactly which sensor is squandering?
Download the Sensor Test or AIDA64 app from Google Play. These tools show the graphs of all sensors in real time. Put your phone on the table: if the accelerometer graph jumps, even though the device is stationary, the sensor is faulty or needs calibration.
Does the turn-on mode β€œIn the pocket” affect the autoturn?
Yes, the proximity sensor used in pocket mode can conflict with the light sensor and the gyroscope, and if the proximity sensor is contaminated or closed with film, it can falsely detect where it is in your pocket and block or reverse the screen.
