I don't know man, somethings wrong with my phone, like you said, everything worked fine for me also but suddenly AU stop work, before 2 days stoped custom alarm tones (when I choose my tone clock just crash) - also I have updated to latest CSSU before 2 days.
File Man is slower also after CSSU. And about AppMan, I use FAM too but sometimes I need AppMan.
Is there difference if I update software from FAM or AppMan?
I have updated latest CSSU from FAM. And is there a any way to reinstall clock?
