    Wi-Fi issue

    The Cyanogen OS 12 and CyanogenMod 12 have a common issue where the dhcpcd sends incorrect data to the DHCP servers. So even though you are connected to the router, you would still receive an invalid IP address and lose the internet connection.

    To fix this issue flash this file.

    Irregular data connection and phone shows 'Emergency Calls Only'

    It looks like the Cyanogen OS 12 has difficulties detecting the default APN. This issue can be fixed. Go toSettings>> Mobile Network>> Access Point Name>> select your carrier.

    If the problem still exists, go toSettings>> Mobile Network>> Network Operator>> select your carrier.

    Can't connect to data but phone call works fine

    Pull down on the top right of the screen to access the quick settings menu>> select the network icon (the right triangle)>> toggle ON (located at the top right of the menu).

    How to increase mobile data signals

    The Oxygen OS is reported to have a stronger reception and data signal. To install this modem on Cyanogen OS 12flash this file.

    Can't send MMS

    Enter the default messenger>> click 3 vertical dots on the top right>> Settings>> Auto-Enable Data>> toggle ON.

    Note that this fix is only needed depending on the carrier. If you receive picture messages and the option is disabled for you, do not enable it.

    Problem detecting SIM card

    Settings>> Security>> Set up SIM/RUIM Card Lock.

    Cyanogen OS 12 theme app issue: can't change lock screen wallpaper to None

    If you want your wallpaper to match lock screen, select the same image and apply it on your lock screen.

    Dialer, numbers and contacts not showing

    Go toSettings>> Theme>> System>> Apply

    Ugly Cyanogen OS 12 theme

    Go to Settings>> Theme>> System>> Apply

    New keyboard does not look good

    Go to Settings>> Language & input>> Android Keyboard (AOSP)>> Appearance & Layouts>> Themes>> select the desired theme. Note that the Halo theme is similar to the KitKat keyboard.

    Decrease settings options

    Navigate toSettings>> About>> Advanced Mode>> toggle On.

    Laggy App draw

    This is a launcher issue. You might download different launchers such as Google Now, Nova Launcher or, Apex Launcher from the Play Store.

    No more tabs on Chrome

    This is said to be a new feature with each tab being treated as a new app in the Recent App menu bar. You can undo this feature by launching Chrome>> select 3 vertical dots on the top right of the screen>> Settings>> Merge tabs and apps>> Off.

    No longer silent vibration via Volume keys

    There is an Xposed module, posted onXDA forum, for this issue.

    Flash Xposed framework

    Install Xposed Installer

    Install True Silent Mode

    Enter Xposed Installer>> Module>> enable True Silent Mode

    Finally reboot your phone

    Fix for inaccurate GPS

    This issue crops up since the location services do not have permission to obtain your location. However it can be fixed from Settings>> Privacy>> Privacy gaurd>> click the 3 vertical dots on the top right of the screen>> enable show system apps>> grant location access toAndroid System, Location Services,Maps, and Street Views.

    Still not fixed? Navigate toSettings>> Location>> Mode>> High Accuracy.

    Low mic

    Email app

    The old Email app has been replaced by a new app from Boxer called E-Mail and you will have to set it up.

    Can't login with CyanogenMod account

    The Cyanogen OS 12 has a new account system called Cyanogen account. The old Cyanogen credentials do not work with the Cyanogen OS 12. You need to make a new account.

    To gain root

    With the installation of the new stock Cyanogen update, the phone will lose its root. Just install SuperSU from Play Store>> launch SuperSU>> follow the on-screen prompts to root your OnePlus One.

    Apps/System crashes constantly

    This happens when you perform an OTA update on your phone with a dirty flash. The fix for it is very simple.

    Turn off your phone>> press Power +Volume Down buttons together>> in recovery mode wipe the Dalvik Cache andCache.

    Since updating to Cyanogen 12, my call service is almost useless. I'm in the UK and on 3 and can't make a satisfactory call. I have already selected the appropriate carrier.
    Anybody have any suggestions?

    So what do you want to say?

    If the above mentioned issues are true, then it's also true that Cyanogen has enjoyed it's Vengeance against OnePlus One.
