How to restart Xiaomi Redmi 7A if the sensor is not working: all working ways

Xiaomi Redmi 7A touchscreen has stopped responding to touch, and the phone needs to be rebooted urgently? This is familiar to many owners of budget smartphones, where hardware fails over time. The problem is complicated by the fact that without a desktop screen you can not use the standard shutdown menu. However, there are at least 5 alternative ways to force reboot, from the simplest button combinations to advanced methods through ADB or Recovery Mode.

In this article, you will find step-by-step instructions for each method, including visual clues and warnings about possible risks. We will also discuss why the sensor may have failed, and what to do if the reboot did not work. Importantly, some methods require preliminary preparation (for example, the USB debugging enabled), so read carefully!

If your Redmi 7A isn’t just “glutting” but is completely silent — it doesn’t react to charging, it doesn’t vibrate or it doesn’t show signs of life — the problem may be deeper than it seems, and then a reboot is unlikely to help, and it’s worth considering whether to restore through Recovery or contact a service center.

1. Forced reboot through buttons (Hard Reset)

The most versatile method that works even in a completely dead screen: Xiaomi Redmi 7A uses a classic combination of buttons, but there are nuances:

✅ Advantages: No screen required, suitable for any version MIUI, no-reset.

❌ Disadvantages: It won’t help if the phone is discharged or the buttons are physically damaged.

Instructions:

1. Hold the Power button and Volume Up button at the same time.
2. Hold them for 10-15 seconds until the phone vibrates and starts to reboot.
3. If the screen is black, try again, holding the buttons for up to 20 seconds.

⚠️

Attention! On some firmware, prolonged button retention can trigger a Fastboot Mode. If you see a hare in a hat, release the buttons and try again, holding only Power + Volume Down.

Make sure your phone is not charging (turn off the cable)

Check if the power button is stuck

Try to connect the charger - sometimes the phone "wakes up"

Hold the buttons strictly at the same time, without delay

2.Reboot via charging connection

If the sensor doesn't work, but the phone is still showing signs of life (vibrates, flashes the indicator), try waking it up with the charger, which works 30% of the time when software crashes.

How it works:

When connected to a charge, the Redmi 7A can automatically reboot if it has been in a “hang” state, especially if the phone is discharged to 0% and does not turn on.

Step-by-step:

1. Connect the original USB Type C cable to your phone.
2. Insert the other end into the charger (preferably on 5V/2A).
3. Wait 5-10 minutes – sometimes the phone will reboot itself.
4. If nothing happens, hold the power button for 20 seconds (even if the screen is black).

💡 Important: If the charging indicator flashes red, it is a sign of a deep battery discharge, in which case the reboot may not work until the phone charges at least 5%.

💡

If your phone is not responding to charging, try using a different charger or cable, and sometimes the problem lies in the damaged accessory, not in the smartphone itself.

3.Using Recovery Mode to Reboot

Recovery Mode is a service mode that allows you to control the phone without a desktop screen. On the Xiaomi Redmi 7A, it runs through a combination of buttons and gives access to basic functions, including reboot.

⚠️

Attention! Don't confuse Recovery Mode with Fastboot Mode! In the first case, you'll see a menu in English/Chinese, in the second case, a picture of a hare. If you're on Fastboot, just reboot your phone with a long Power hold.

How to get in to Recovery:

1. Turn off the phone (if it's on, hold the Power for 10 seconds).
2. Press the power button and the volume button at the same time.
3. Release the buttons when the Mi logo and Recovery menu appear on the screen.

How to restart your phone in Recovery:

• 🔄 Use volume buttons to navigate the menu (up/down).
• ✅ Select Reboot or Reboot to System.
• 🔘 Confirm the choice of the power button (Power).

If the menu is in Chinese, focus on the first or second item – it’s usually a reboot.

4.Reboot via ADB (for advanced users)

If you're on your Redmi. 7A The previous debugging was included USB (USB Debugging, you can restart your phone through your computer using a tool ADB (Android Debug Bridge: This method is suitable if the sensor is not working, but the phone is determined by the PC.

• 🔌 Cable USB (preferably original).
• 🛠️ Installed Xiaomi drivers and package ADB Tools.

Instructions:

1. Connect the phone to the computer.
2. Open the command line (Windows) or the terminal (Linux/macOS).
3. Enter the command: adb devices If the phone is determined (the serial number will appear), proceed to the next step.
4. Run the reboot command: adb reboot

⚠️

Attention! If USB debugging wasn't enabled in advance, this method won't work. Also, don't use the adb reboot bootloader or adb reboot recovery commands, which put your phone into modes that are difficult to exit without a desktop screen.

💡

ADB is the safest way to reboot if the phone is recognized by the computer, but it requires pre-setting and is not suitable for a clean smartphone without debugging.

5. Alternative methods: battery and service centers

If none of the above methods worked, the problem may be a hardware malfunction.

1. Battery recovery (for experienced users)

The Redmi 7A battery is non-removable, but with experience and tools, it can be temporarily turned off:

• ⚠️ Risk: loss of warranty, damage to plumes.
• ✅ Effect: Complete power reset, similar to battery extraction.

How to do this:

1. Remove the back cover (need a mediator or plastic shoulder blade).
2. Disconnect the battery plume for 10-15 seconds.
3. Connect back and try to turn on the phone.

2. Contact the service center

If the phone is warranty or you are not confident in their abilities, it is better to take it to an authorized service Xiaomi. The average cost of sensor diagnostics is 500-1000 rubles, replacement is 1500-3,000 rubles (depending on the region).

Why the sensor on the Redmi 7A does not work: the main reasons

Rebooting can only help with software failures, if the problem is hardware, you'll need repairs.

Mechanical damage

• 💥 Fall or impact – even a minor physical impact can damage the sensor plume.
• 💦 Moisture ingestion - oxidation of contacts leads to unstable screen operation.

2. Programmatic errors

• 🤖 Failure MIUI — After updating or installing applications, conflicts may arise.
• 📱 CPU overheating – if the phone has been under load for a long time, the sensor may “hang».

3. Wear of components

• ⏳ The ageing of the sensor layer - at Redmi 7A A budget matrix that loses sensitivity over time.
• 🔋 Bloated battery – can press on screen plumes, causing crashes.

🔍 How to Diagnose the Cause:

If the sensor sometimes works (reacts to touching in certain areas), the problem is more software, if the screen is completely dead (no backlights, no charging reactions), the "iron" is to blame.

What to do if the reboot does not help?

If none of the methods worked, follow this algorithm:

1.Check the charging response

• 🔌 Connect your phone to another charger.
• 🔋 If the charging indicator flashes red, the battery is dead. Wait 30 to 60 minutes and try to restart again.

2. Try connecting to the PC

• 🖥️ If the computer makes the connection sound USB, But the phone is not detected - the problem is the firmware.
• 🔄 In this case, only flashing through Fastboot will help (instructions are on the forums). 4PDA or XDA Developers).

3. Contact the service

• 🛠️ If the phone is warranty, do not disassemble it yourself - this will void the warranty.
• 💰 The average cost of sensor repair on Redmi 7A — 1500–3000 rubles (depending on the region).

⚠️

Attention! If after the reboot the phone is turned on but the sensor is still not working, do not try to use it further without repair.This can damage the motherboard due to improper distribution of current.
