Hi everyone, I just got this problem which was probably caused by banning the self-start of some android system application. I used a third party application to ban some system applications in order that they won't start up automatically and consume too much memory. But obviously I did it too much so that when I long-press the power button now there is no pop-up menu for power off and restart, and I can't recall all those system applicaitons I banned. Could you please help me to find that very system application for allowing it to automatic start? My system is Android 4.4.2, rooted. Thank you.
