How to do a hard power off on Samsung A5?

[Tom2827]

My mum has an old Samsung A5 phone and she's clicked on something that has messed the phone up real good, looks like some kind of virus that has locked up the phone with a generic "Downloading do not turn off" splash screen.

Can't access anything on the phone, the splash screen has just locked everything down, and holding the power + volume down for a manual reset doesn't work either, the screen just goes black for a few seconds, then immediately lights back up onto the splash screen.

I need a way to manually do a hard reset on the phone, like unplugging a battery would do. Can anyone help me out with some pointers?

It sounds like the device may have experienced a software malfunction or virus infection that has caused it to become stuck on the "Downloading do not turn off" screen.

To perform a hard reset on the Samsung A5 phone, you can try the following steps:

1. Press and hold the power button and volume down button simultaneously for about 10-15 seconds, until the device vibrates and the Samsung logo appears on the screen.

2. Release both buttons and wait for the Android system recovery menu to appear on the screen. This menu allows you to perform various system maintenance tasks, including a hard reset.

3. Use the volume buttons to navigate to the "Wipe data/factory reset" option, and then press the power button to select it.

4. Confirm that you want to perform a factory reset by selecting "Yes" on the next screen.

5. Wait for the device to erase all data and reset to its original factory settings. This process may take several minutes to complete.

6. Once the reset is complete, select the "Reboot system now" option to restart the device.

Please note that performing a factory reset will erase all data and personal settings from the device, including photos, contacts, and app data. Make sure to back up any important data before proceeding with the reset.

If the hard reset does not work, you may need to take the device to a professional repair service or contact Samsung customer support for further assistance.
