How can I disable it, that when my phone is pattern locked, the title bar (system/info tray or info bar how ever is it called) is still draggable?

I have a pattern lock but when locked it is just possible to drag down the title bar and than all these shortcuts are enabled.
Bad this, when phone in pocket.

And on CM12 there is this nice popup feature for any message, which makes the title bar active as well, without any press of home or power button.
This makes it impossible to lock the phone totally, only when airplane mode is active (to avoid any message), but then a calendar message could popup.

I am 12.0 latest nightly on i9505

EDIT: it seems to be a Bug, and as CM12.0 is abandoned I just might live with it :(

spamming my colleagues, bug in exchange calendar

Dear developers,
Thanks for your work. I'm really enjoying this ROM. But now I experienced a problem...
Since last Friday I experience a not so funny bug, which I can only relate to the standard mail client and 'exchange services' in the package... It turns out that even after un-installing all exchange related apps, after deleting all 'accounts' related to exchange, and after deleting all (old) data in the 'apps'-settings in the settings menu of the phone, it is able to continue to send 'Accepted: Project group meeting' messages to the colleague who entered the original meeting in the agenda. And not just once, but every few minutes. Thousands in total.

Now it only stops when I restart the phone or when I go into airplane mode. After opening the mail client once (even without entering a new exchange account) it starts again. There must have gone something wrong in the registries or whatsoever. And it all started after installing the app "Exchange Calendar Sync" play.google.com/store/apps/details?id=it.mp.calendar.sync, which I installed because the standard mail client/exchange services wasn't syncing my calendar anymore (but still syncing mail and contacts) from the exchange server of my work.

Maybe I need to do a factory reset... But first I thought I tell you guys. Maybe there is a logic answer for this.
Best regards!

I found the error. It was more logic than expected. I had the same sync app (Exchange Calendar Sync) installed on my wifes phone... It stopped when I switched off two way syncing. I will send a message to the maker of this app.
Best regards!

Baseband Uknown 20150625-NIGHTLY

I have "Unknown" in baseband field with cm-12.1-20150625-NIGHTLY-jfltexx. Ofc network doesn't work at all. Wi-Fi and Bluetooth works fine. Haven't tried all previous versions, but with cm-12.1-20150620-NIGHTLY-jfltexx everything works fine. As for baseband version, I had XXUHOD7 which was changed to the latest XXUGNG2 as possible workaround. I did not hepled at all, but with 20150625, but with more early 20150620 build it works as intended.

Hello there, hope this the right place for a bug report.

On 20150717 I still have a (software-) problem with the gyro. If i turn on automatic Rotation and rotate the s4, it rotates but only one time. After that nothing happens if i rotate the device. After goin back to the homescreen it works again, but only one time again...

Found a lot more bugs in the last days but i just flashed the newest nightly, so perhaps they already fixed. I'll report later.

Wishlist: The originally used camera in samsungs Firmware (android 4.x) was way better.. Especially contrast / colors. Would be fine to have a similar one in CM.

Thanks to the developers..! My mobile runs better with the cm nightly than with original Stockwerk firmware. :)

Can't boot after enabling Full Disk Encryption

After the Full Disk Encryption, it asked for the password when turning the device on, then goes to the cyanogenmod logo and stays there for hours and hours.... Is this a known issue?

can someone tell me how the stock browser of CM12 is working?
I mean the com.android.browser, Package Version 5.0.2-2b1f...(21)
I am not able to open a page, because there is no address line visible. Is this a bug or just my missing knowledge?
I tried many things, startpage blank, and so on, but no address bar, where I could enter any address to open.
It opens the startpage, when I edit one in the settings, but I cannot access the address field of any site.

Other question: not possible to store a website offline locally with this "cm-stock" browser, is it?

EDIT: found it myself. It is the Labs Setting which is buggy. When I disable the thumb control in Labs in the settings, the address bar is back (I can pull it down now). So that Labs setting is buggy.

I am on the June 10 nightlies. Charging my battery takes very long, like up to many hours (5-10). This happens with different batteries. I have 2 extra batteries. Is this a bug?

Same problem here. Your phone is charging in USB method. Best way so far is literally unplug then replug and refresh battery stats, if it changes to AC your good other wise unplug both sides of wire and then replug. Also if you don't feel like doing all that you can open Stweaks and set usb charging to 1000mAh which is a bit less than by AC but definitely better than the default 400mAh.

Can we do this by default in the rom itself instead of stweaks

    We have de-unified the Galaxy S4 line. Too many issues with having them all in one and a maintainer's nightmare. Look for jfltexx builds now as opposed to the jflte builds you previously used.

    This is not the place to talk about custom kernels, don't report bugs/errors if you use one.

    I know that me and @alucard_24 work together on our custom ROM but this is official CM.

    Original Alucard kernel isn't updated with new stuff, this means broken sensors etc. Only Alucard in our CM custom builds is updated for now (we had to test it, that's why you still don't have an update available)

    GPE system size is being fixed in upcoming build

    For those having a greenish screen on latest nightly:
    Go to Settings -> Display & LED -> LiveDisplay -> Color calibration and set all sliders to about 50% (I have red=50%, green=47%, blue=51%)
    Then press OK, switch off the screen (power button) and switch on again -> voilà, natural colors!
    Till 1st lollipop snapshot is released :D:D
