The situation when the screen Xiaomi Redmi 7A continues to show the image but stops responding to touch, is one of the most stressful for the owner. the device may freeze, require a reboot to install updates or simply work incorrectly, but the standard method of shutting down becomes unavailable. At this point, it is important not to panic and understand that the physical failure of the digitizer (the layer responsible for input) does not always mean a complete loss of control over the system.
There are several proven methods for making a forced reboot or even a full reset without touchscreen, which range from simple button combinations to computer software, and the specific method depends on whether the phone is on at all and whether it responds to any external commands.
In this guide, we will discuss all possible options for resuscitation of Redmi. 7A. We will look at hardware buttons, capabilities USB-It is important to act consistently so as not to damage the software of the device.
The method of hardware reboot with buttons
The fastest and safest way to bring a device back to life is to use physical control buttons. Xiaomi smartphones have a forced restart feature that works even when the operating system is completely frozen. For the Redmi 7A, this procedure is standard and does not require a connection to a computer.
You need to find the power button, which is on the right side of the body on this model, and sometimes just pressing that button causes a shutdown menu that you can't use. So you use a combination or a long hold. 10-15 The screen should go out, and then the Mi logo will appear.
⚠️ Warning: If the phone is in a case, remove it before the procedure.The case may interfere with the full press of the button, and the system will perceive this as a short touch, launching the voice assistant instead of restarting.
If a single clamping didn't work, try a combination of volume and power buttons. Press the Volume Up button and Power button at the same time. Hold them until the device vibrates or the logo appears. This method is often used to enter recovery mode, but with prolonged retention can initiate a restart.
☑️ Pre-reset check
Use of the USB-screen-control
If the screen is on, but the sensor is not working, and rebooting the button does not solve the problem of suspended services, you can try to access the interface. A unique feature of the Android platform and the MIUI shell is the support of OTG (On-The-Go) technology, which allows you to connect peripherals to the smartphone, such as flash drives or a computer mouse.
To do this, you'll need a USB to Micro-USB adapter (since the Redmi 7A has a Micro-USB port) and a simple wired mouse. Connect your mouse to your phone through an adapter. You'll have a cursor on your screen that you can control by moving the manipulator around the table. With the cursor, you can unlock your phone if you know the pattern lock and go to the menu for a regular reboot.
- 🖱️ Connect. OTG-port-adapter.
- 🔌 Put it in. USB-mouse-jack.
- 👆 Wait for the cursor to appear on the display.
- 🔄 Use the left mouse button to navigate the "Switch off" or "Reboot" menu".
This is ideal if you need to save data before resetting or just shut down the system normally, but if the phone is completely locked and does not respond to the virtual keyboard (even with the mouse), this method may not work without first unlocking.
💡
Use a mouse with a scroll wheel to quickly flip through contact lists or settings if the sensor is completely dead.
Reset to factory settings via Recovery Mode
When the sensor is down and the phone needs to be not just rebooted but completely cleared of data (for example, before selling or when critical software errors), Recovery mode is used. This is a special diagnostic interface that boots separately from the main operating system, and is controlled exclusively by physical buttons.
To enter Recovery mode on Redmi 7A, do the following: turn the device off completely (if it's on, press the power button to vibration and release, then immediately proceed to the next step). Press the Volume Up button and Power button at the same time. Hold both buttons until the Mi logo appears, then release the power button, but keep the volume up until the Recovery menu appears.
In this menu, the touchscreen doesn't work by definition. Navigation is done with volume buttons (up/down), and the power button selects the item. You need to find the Wipe Data item. After you select, confirm the action by selecting Wipe All Data. The process takes a few minutes, after which the phone will prompt you to go back to the main menu (Back to Main Menu) and select Reboot.
| Action on the menu | Navigation button | Confirmation button | The result |
|---|---|---|---|
| Item-by-point relocation | Volume Up/down | - | Cursor moves |
| Choice of menu item | - | Meals (short) | Submenu transition |
| Data reset (Wipe) | Loudness | Nutrition | Deletion of all data |
| Reboot (Reboot) | Loudness | Nutrition | Starting the system |
⚠️ Note: Wipe Data permanently deletes all photos, contacts and applications, and can only be recovered from a backup of the Mi Cloud or Google cloud if it was taken in advance.
Control via computer and debugging via USB
For advanced users who had debugging on the phone in advance USB (USB Debugging, which allows you to have full control of the device through the computer, allows you to send reboot commands directly to the core of the system, bypassing the broken sensor.
You'll need a PC, USB-cable and installed drivers ADB (Android Debug Bridge. Connect your phone to your computer. Open the command line or terminal in the tool folder. ADB. Enter a command to check the connection:
adb devicesIf the list shows a device with device status, then the connection is established. To perform the reboot, type in the command:
adb rebootIf you want to log in to Recovery mode for further reset, use the adb reboot recovery command, which is most effective because it allows you to diagnose the system condition, make full data backups before resetting, or remove problematic applications that caused the sensor to freeze.
What if the ADB can’t see the phone?
Reasons for sensor failure and software solutions
Before you bring a device to service, it's worth analyzing what exactly caused the touchscreen to fail. Often the problem is not physical damage to the matrix, but software failure or resource conflict, and understanding the cause will help prevent a recurrence of the situation after the reboot.
One of the common causes is overheating of the processor. Redmi 7A is a budget device, and when you put a lot of work on it or use a heavy case, it can heat up. When you reach a critical temperature, the system can programmatically turn off the sensor layer to protect the components, in which case simple cooling of the case helps.
- 🔋 Battery discharge: At low charge, the voltage may fall, causing the digitizer to work incorrectly.
- 💾 Overflowing memory: If the data partition space is less than 100MB, the system can behave unpredictably.
- 📱 Conflicting application: A newly installed program could have introduced a virus or created a driver conflict.
- 🧊 Low temperature: In the cold, the capacity of the sensor layer drops and it stops responding to touch.
If the sensor is running after the reboot but is not running smoothly (missing taps, phantomite), try removing newly installed apps. It’s also worth checking for system updates in the settings menu, as newer versions of MIUI often fix driver errors.
When hardware parts need repair
If none of the software methods worked, and the phone doesn't even respond to the mouse or ADB command (assuming the debugging worked before), it's likely that the problem is physical.The Redmi 7A uses a separate plume for the sensor that could have moved away from the board as a result of a fall.
Careful tapping on the body or light pressure on the top of the screen (where the plume connector is located) sometimes temporarily returns to work. If this helps, then the contact is broken. However, constant pressure can damage the matrix, so this method is only a temporary solution to save data.
💡
If the phone responds to volume buttons (the volume of the sound changes), but the screen is black and does not respond to the touch, it is most likely the problem in the display plume or the matrix itself, not in the software.
When the phone falls, falls into the water or is heavily compressed, replacing the sensor or display module assembled is the only right solution. Self-disassembly Redmi 7A requires skills, since the back cover is glued and warmed by a hairdryer, and the plumes are very thin and easily tear.
