I used to check whether my phone (Samsung) is functioning well by dialing *#0*#

But as of now I bought a new Samsung A10s but I'm failing. What could be the reason?

Hi Eulo25 

Is there an error message that you get when dialing that code?

Nothing pops

You can perform a soft reset of your device.

Press and hold the power and volume-down buttons for about 10 seconds.

*The device may take a screenshot, however, keep holding the buttons for a few more seconds.

So does this mean my files and accounts won't be lost during the soft reset process?
