sergiofcl , via OnePlus 3 , Feb 20, 2020 : Hello. Have installed Havoc OS 3.0 at a few days ago, and today I've noticed that the alert slider is not working properly - down position don't do nothing, so I only have the option of ring and vibrate on the two other above. I can almost swear that it was running fine right after flashing the rom. Can anyone please help me? Thanks in advance.
