after installing 2nd booth app (nothing else) the phones start to have screen wake up delay, just like now, 2-3 sec. Is it possible to exist some connection or is just coincidence!?
Have you tried changing your governor settings for better wake-up performance? The default governor (Interactive) is set to limit the CPU frequency to 600 MHz when the screen is off, which can cause slow wakeup. In Aero Control, try changing the governor to OnDemand (or set suspend_enabled to 0 for Interactive governor). That might help.
