How to Forcibly Turn Off OPPO F21s Pro 4G

Although the Android operating system is relatively stable, it is not uncommon for it to malfunction. To solve the problem, it is often enough to turn off the OPPO F21s Pro 4G and then switch it on again. The smartphone will then resume its usual mode of operation.

Standard ways of turning off

If the OPPO F21s Pro 4G is running as usual, it can be shut down using Android's built-in tools. A total of two shutdown options are provided.

Pressing a physical button

The easiest way to turn off your smartphone is to use the power key, which is located on the right-hand end of the device. To shut down you will need:

Press the "Power" button.
In the window that appears, select the "Power off" option.
Confirm the operation.

The phone screen will then extinguish and the phone will shut down. If the power key is unresponsive, or if you just want to be aware of alternative shutdown options, consider terminating via the Quick Access Toolbar.

Quick Access Toolbar

This option is suitable for people who don't want to or can't switch off the OPPO F21s Pro 4G using the physical button. The shutdown menu can be called up using the secondary menu:

Lower the notification curtain.
Press the button in the form of the common "Off" icon.
Select the "Power off" option and confirm the action.

In this way, you don't access the physical "Power" button when you're finished, but only the touchscreen layer of the screen performs the operation.

Alternative ways of turn off

Next, let's look at more scenarios on how you can forcibly switch off your OPPO F21s Pro 4G phone if you forget your password or on a device with a broken screen, for example.

Switching off the OPPO F21s Pro 4G without screen

If the OPPO F21s Pro 4G's sensor is not working and the smartphone is not responding to screen touches or if screen is frozen, you can try power off the device with a black screen using the buttons. More specifically, it is suggested that you press the Power and Volume Down keys, holding them down until the display goes out. This usually takes 10-15 seconds, and the phone switches off without the sensor.

How to turn off the OPPO F21s Pro 4G without a password

If you forget your password, you can switch the phone off in the standard way by pressing the power button and selecting the 'Power off' option. It's true that some OPPO F21s Pro 4G owners complain about the lack of a pop-up menu on the locked screen. In such a case, it is recommended to force a password-free shutdown via Recovery Mode:

Perform a forced reboot as described above.
Press the volume up button and the power key.
If done correctly, you will be taken to Recovery Mode where you need to select the "Power Off" option. Use the volume knob to move between menu items and the power key to confirm actions.
If you want to unlock your smartphone, go to "Reboot system now" and confirm the reset.

Only perform the last step if you are prepared to lose personal data to regain access to the main menu. If you just want to switch the phone off, use steps 1 to 3.
