@Pandolin said in Volla Phone Quintus: How to Disable the Security Warning on Volla Quintus after flashing Volla OS?: every time I boot up the device, I get a security warning indicating that the device might be corrupted. That is completely normal for most of us who use devices that previously ran Android. The best option is to see it as a badge of honour, awarded for freeing the device from Google's clutches.
