i would like to report SpeedMOD 4.4.4 - 3.0 Beta #2 bugs as well.
1. Reboot frequently automatically when phone in use.
2.Screen blackout automatically when phone in stanby, no respond when touch/press anything, need to unplug battery.
3. Play Store graphics are broken same as others, i was try pa_gapps-modular-micro-4.4.3 and gapps from CyanogenMod 11.0 (Liam D) also same the graphic are broken.
4.This is the critical issue i was facing in 3.0 Beta #2, sceen stuck in speedmod bootlogo. phone in stanby as well, phone won't bootup. i was try unplug battery many time or wait also won't boot, the only way is boot to cwm/twrp recovery re-flash everything.:crying::crying::crying:
I also faced similar issue no. 2 that you reported sometimes phone is impossible to wake when on 2G/3G internet no issue when on WiFi. This problem also existed in the SM 2.5.1
