The EQ preset that I tied to phone loudspeaker turns EQU and TONE off by itself, the LIMIT stays on. I don't know what causes it and when exactly does it happen, but it pisses me off because I have to turn these on manually every time I want to play music on the loudspeaker. This didn't happen before 820 I believe. I am using dark default skin for Poweramp, on my Xiaomi Mi A2 Lite.
