Yes, i have tried like all modems/bootloaders. Tried changing routers firmware, channels etc. If i install cm11 working perfect. So its cm12 problem. I have read cm12 have different wifi drivers so i still hope cm team will fix wifi. I think they know the problem. Alucard tried to fix it in latest kernel but still not succesfull

I use gapps-lp-20150417-signed.zip with 5.1.1 CyanogenMod 12.1 Nightlies. Did a dirty flash over cm-12.1-20150413-OPTIMIZED-jflte and don't have any problems yet. Everything works well.
Thank you Antares.

@AntaresOne Is it possible to tweak the stock CM kernel using Device Control app from the play store, since it's not suggested to use custom kernels for bug reporting? Thanks
Noob question:
If I enable rooting, what type of rooting should I choose that is the same with supersu? What is the difference between app and adb root?
Please answer, I really want to know this stuff. Thanks!

This is not the right place to ask this question... anyway, app is for apk root privileges, adb for root privileges in debug mode... if you are not familiar with adb, you can avoid to enable for it. If you search around, you can find info about this matter. Close OT

CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

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 going to be a slightly long post. I started digging in to the Bluetooth problem, because it's been bothering me since, well, forever, both on Galaxy S4 (I9505) and S2 (I9100). Turns out its quite a mess with multiple moving parts, so to speak.
First thing I found is that the Broadcom vendor library for Bluetooth is missing an implementation for a function called "ssr_cleanup". Our S4 uses Broadcom, so this is definitely an issue. The implementation is missing all the way upstream in AOSP sources.
File in question: https://github.com/CyanogenMod/android_hardware_broadcom_libbt/blob/cm-12.1/src/bt_vendor_brcm.c (Google: https://android.googlesource.com/pl...libbt/+/android-5.1.1_r4/src/bt_vendor_brcm.c)
This missing function causes the following error in the log:
I did my own implementation for this, mimicking the ssr_cleanup in Qualcom BT vendor lib. Compiled, replaced /system/vendor/lib/libbt-vendor.so and "Fatal signal 11" disappeared from the logs. Just as expected.Code:E/bt-hci ( 3577): Num consecutive HCI Cmd tout =2 Restarting BT process E/bt-btif ( 3577): bte_ssr_cleanup F/libc ( 3577): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 9919 (bluedroid wake/)
However, this is NOT what causes the random BT disconnects. ssr_cleanup is just what happens after BTU HCI commands timeout twice consecutively.
When BTU HCI commands time out twice consecutively, the following takes place:
- ssr_cleanup is called
- wait 20 milliseconds
- "Killing the process to force a restart as part of fault tolerance" (i.e. the Bluetooth process is killed)
Of course, this didn't help, because things have already gone wrong when the HCI commands are timing out.
As a note: at this point, the Bluetooth connection was stable for a random length of time (first test 3 hours, this morning a few minutes). Once the HCI commands start timing out, the connection will become unstable, possibly disconnect from my computer/car's handsfree, and it will remain so until Bluetooth is restarted. Of course, with the modifications I had implemented, the BT process was not automatically killed/restarted.
I googled for "BTU HCI command timeout", and found that it's a common problem for at least Samsung Galaxy S3, Nexus 5, and HTC One. On StackOverflow, somebody commented that: "Of note, with specific code, the Galaxy S4 will automatically reconnect when this occurs, leading us to believe there is an issue in the BLE stack that Samsung identified and developed custom handling for." So Samsung may have implemented a way of quickly restarting the BT process without interfering with the ongoing connections. I have noticed when using I9505 GPE 5.0.1 that sometimes the BT connection becomes unresponsive for a second or two, but then just resumes without disconnecting.
So what this boils down to is:
- We need to find out why BTU HCI commands are timing out, and can we avoid it?
- Figure out how to recover from this situation without breaking the Bluetooth connections
- Or at least quickly connect/disconnect when faults occur
Bluetooth works just fine for me on stock TW or GPE roms, but I really like CM much more because of its smoothness and functionalities...
I have thought of replacing the CM Bluetooth with GPE implementation. However, I do not have the skills for that. Simply replacing the BT-related .so and .apk files ended up in loads of FCs.
@AntaresOne Any idea how to start fixing this BT?17
So, the point of sending patches to gerrit seldom makes some people acting bad saying that somebody or his work are useless. I have never been a fulltime developer with all the other things I have to do outside jf and while jf tree is practically done. You started comparisions between me and another maintainer, now seriously, do we need that? What can you get from it?
Some people still think that CM maintainers are paid, so I'm basically nothing more than a thief since I'm committing once in a period. Now dear people, CM maintainers are NOT paid. I am in Italy, not in the U.S., situation is very bad and quality of life terribly decreased. More than "losing time" on something which doesn't give me any form of payment I focus in working on what can really give me some money back, but I'm glad to commit on gerrit when needed.
If the dev(s)/maintainer don't read this thread (busy with work and personal life, summer etc.) is defined as useless, right no?
Optimized ROM is how I personally want CM, and 99/100 things inside can't be added to official CM due to how these things work. I am free to do whatever I want.
"Why do we need", remember you're not paying for what you can find here. You can't say that in respect of me, my team and whoever spends time doing something for the community. Very bad, rude and offensive. @feydakin: you used that ROM and now saying that is useless, nice job...
How many times I asked for a log and didn't get anything? I always checked this thread daily and daily wrote here before half of June. Even if I'm not writing I'm still always checking. Don't be bad and arrogant with me only because @dcd1182 is here, but keep intact your common sense, respect in me and seriousness as it was before. I have never been arrogant or disrespectful with you.
Lastly, just for the chronicle, my XDA activity decreased a lot since June (I have a personal life, don't know about you) and I'm sorry if I missed many messages.
Close OT.
Hello,
I would install the most recent, always contains latest patches which are not available in the older builds
EDIT: I saw the other user said that every build after 4 August has issues with LiveDisplay. So install that one, I can't check myself if it's actually working or not at the moment
