    I'm having a rather weird problem. I grouped my apps into a private folder and locked it. As expected the apps disappeared from the app drawer. Later when I released the apps, one app particularly (xodo PDF reader) failed to reappear.
    I checked the apps list and it has disappeared from thr too. When I reinstalled from app backup, it asked me if I wanted to update the existing app. And despite reinstalling it five times it doesn't seem to appear in apps list. It open fine when I open through recent apps tab. I'm really confused

    Need help please can't unlock my phone, have forgotten the pattern and the 12 update removed the "I forgot my pattern" button. I have also tried the Google Device Manager but there is a bug with that at the moment.

    And somehow i just noticed this when i went back from r38 to r33. After i updated to cm12s the problem still remains so i decided to wipe the system and reinstall cm12s but its not fixed....I thought my wifi was broken but since u have the same issue, it might be just a bug. Sometimes when i tried to manually connect my wifi to the router and it doesnt work, the phone crashes and reboot. Its really annoying to have a system with so many flaws. Its cheap yeah but at least make a descent software with less noticeable issues -_-

    For those people who have problem with sending/receiving MMS here is the work around:
    1. Delete all APNs that are not related to your sim card provider.
    2. Download Google Messenger app from Play Store to use.

    Works perfectly for me. I hope the next upgrade rom will fix this problem so we can use the stock Android Messenger again.

    Not sure if this was mentioned but:

    How can i set it so that tapping a signal icon would toggle data connection like in 11s.

    And wtf is this new lockscreen, like it requires random swipes to unlock. Specially since the downward swype doesnt work.

    That means you are neither connected to Wi-Fi nor Mobile data.
