Oh didn't know, so it's a known problem everywhere.
Another bug I found is that it doesn't save the SIM card options. I have 2 sim installed, SIM 1 as main card and SIM 2 for mobile data. But every time I turn off the phone and turn it on again mobile data are off for SIM 2 and on for SIM 1.
The same happens in the realme settings where game mode is enabled by default. I disabled it, but when you turn on the phone again it's enabled
