Hi, I'm new to MIUI, and was used to Sense 2.5 for my DHD before switching. My company's exchange sync, enforces a pin code on my phone, but on Sense i was used to a setting where I could delay the password (pin) prompt for up to 15 minutes. So if I unlocked the phone and it was less than 15 minutes since last I put in the pin, it wouldn't prompt me for pin again. But with MIUI it does it every time I've locked the phone, right after screen timeout, and its pretty annoying, and I can't find where to change this! I have the screen timeout set for 1 minute, but then it locks the phone, and then I have to retype the pin code before I can unlock again... Help?
