Yesterday, I flashed the test build from 21 Feb, coming from CM11.

I did a complete wipe (cache, dalvik, system and also data. Additionally formatted the internal SD)

1) I wasn't able to acquire root, though it was activated. I rebooted but nothing changed. I installed SuperSu (I know that it was not supposed to) and suddenly got root. I could have tried to disable root and enable again, but was tired already of this not working.

2) Not able to set governor. With CM11, I always set my phone to power save as battery drain and heat output are not to my taste with any other governor. Performance is fine for me with power save governor. During the 10-15 minutes with CM, the phone was too warm for my taste. As I can not set the governor in the test build, it's another reason for not continuing with this.

I think there was something else, but after these 10 minute, I knew already that CM12 is not ready for me yet.

Thanks to all you guys who are testing it. Maybe in the far future, there will be a version which is better. Looking forward to an official nightly (maybe end of this year, regarding the development speed with this GearCM here).

I switched from kitkat PA myself about a week ago but never had any of these problems...

Hey in the latest build the recent apps screen has a "Couldn't add widget" thing at the top. I forget what's supposed to be there.

BT connectivity

Hey [MENTION=2386505]Alberto96[/MENTION],

I have another BT related issue.

In my car I need to enter a code to pair my phone with the car BT.

But every time I turn off the engine and the car BT turns off - next time I turn it on I can't make the connection.

If I remove the car BT from the "connected devices" on the phone and pair the device again ( enter the code ) it works again untill the next reboot.

This does not happen with BT devices that don't reqire a code to pair with the phone.

It was working on your older builds up untill 0119. Judging by your changelog it could be CM sources related.

After this update it stopped working.

Could you look into it?

Thanks
[Galaxy S 4 General] body150165:
Did you install the "stable" version from 14 Feb or a test build? I installed the test build from 21 Feb and had this experience.
[Galaxy S 4 General] dandemonic:
Full wipe clean install of 21 Feb build, (wipe system, data, cache, dalvik) had no problems with enabling root, and was able to set governor.

Only issue for me was stock messaging app fc, now fixed in 22 Feb build, (also clean flashed).

It's normal for device to be quite warm for several minutes after first boot of a lollipop based rom, due to initial ART processes.
[Galaxy S 4 General] dannyb0i:
Full wipe before switching to CM12 and dirty flashing just about every update since - never had any problems people been reporting save for the occasional sound disappearing after unplugging headphones etc and that's no biggie 4 me

Only Updated CM Sources
[Galaxy S 4 General] AmirDekel:
Alberto nice work please publish the new builds on the main page
[Galaxy S 4 General] zetlaw:
Alberto the 2202 version is great for me. I'm not using Bluetooth so its not an issue.

Although I have few issues I want to note.

1. Mic volume on headset is really high. I can hear my heartbeats :)

2. CPU governor need little tweaking. I watched a show the CPU was on 15% but it was on 600 MHz. Tried using trickster to tweak but every few minutes the settings goes back to default.

Please address those.

Thanks.
[Galaxy S 4 General] hajyihia:
one day with the rom and so far very good, couple of bugs i found ( mostly known ) :

1. phone heats really bad when using chrome and browsing pictures, its like there is a smell of something burn

2. wrong colors while playing videos, and slow videos

3. when playing "fun run 2", the game lags a lot, more than TW roms

so far thats it...but i am very pleased...its smooth...THANKS for the developers...:)

EDIT: is there a way to add double tap to wake the up phone?? kernel??
[Galaxy S 4 General] Alberto96:
If even stock LL is running bad for you then i don't know.

As i said before, frapeti's (member of TeamCanjica) behavior isn't as good as it should be. (open-source doesn't mean copy others work/commits without giving any credit - e.g. commit authorship -), so i won't collaborate with him. And what he says about me isn't true. (kanged commits or something like that)

Just try both ROMs (frapeti's one and mine) and choose your preferred one. I won't say you which is the best one because it isn't fair - even if frapeti is not loyal to me -.

You're welcome.

Install latest GearCM Recovery and retry.

Search Bar, fixed on latest builds.

Uhm...unfortunately i don't have a device to test it with so without logs it will be difficult.

1) Hahah xD Ok, i'll reduce it.

2) It is the normal behaviour :/

1) O_o "its like there is a smell of something burn" WTF. Is your phone working fine???

2) Check first post, known bug. (and you'll see that there's a workaround)

3) I'll check what i can do to fix it :)
[Galaxy S 4 General] GadgetAvi:
Haha, I see that you are flowing his thread too, as I said to him, I'm not a dev, but I was wishing that in XDA all developers are "all for one and one for all"... It is a shame that there is an Ego games here too... I like open source and that's why I prefer AOSP than samsung's official Lollipop...

Anyway, as I remember from CM11 days (not long ago) you are one of the official cm developers right?

is there a reason that there is no official CM12 builds right now? I hope that the core team didn't gave it up, I can understand that Exynos devices are pain in the butt... grrrr, SAMSUNG@@(#@$ It was such a mistake buying I9500 :(

Ok man, I'll try your rom too, lol, looks like I'll change rom every weekend :laugh::p
[Galaxy S 4 General] Alberto96:
Yes i'm an official CM device maintainer (together with [MENTION=1815755]intervigil[/MENTION] ). CM12 Official Support is WIP. :)
[Galaxy S 4 General] Alberto96:
1) I'll try to fix all BT issues ASAP

2) Over-Heating while ART cache is generated causes audio to disappear (overheating protection)

3) CM Sources Related

4) I can't help you with hardware issues, sorry :(

5) ...strange bug...
[Galaxy S 4 General] Duzzar:
Alberto have you noticed latest builds (Currently on 20150223) being slower (some general random lags when pressing home button, opening some applications, keyboard popup, but always randomly, maybe 15% of the times) than older builds (like 20150206)?

I think random lags appeared after the recent "ART optimizations" commit which was supposed to make it faster
[Galaxy S 4 General] mr_mtc:
Hi [MENTION=2386505]Alberto96[/MENTION], thanks for the quick reply and acknowledgement on the issues :) I know you can't help with the hardware issues, but I thought I'd post it here in case anyone else is experiencing the same issue :( Great ROM regardless :D Thanks again! I hope your studies and exams are still going well!!
[Galaxy S 4 General] Alberto96:
Sincerely i haven't noticed it, but i could be wrong. I'll release a new test build in the next hours.

Yes, they're going well (for now...). :) Thank you.
[Galaxy S 4 General] hajyihia:
THANKS, about the overheating, the phone gets really hot, i mean you almost cant hold it, it doesnt lag, its just too hot, and yes if you try to smell the phone from a few centimeters you will know what i mean...still it doesnt lag, and fun run 2 is weird, sometimes its so smooth and sometimes lags a lot....anyway THANKS for this awesome rom....finally a cm rom with clear audio through the speaker although on the low side....

[MENTION=2386505]Alberto96[/MENTION] You said that in GearCM Recovery is to enable F2FS file system, not found any option or something similar, I just installed the GearCM Recovery and updated the latest build, Settings, etc found nothing. Have to format to work?
[Galaxy S 4 General] melekbarca:
What 's the advantage in enabling F2FS file system instead of ext4 ?
[Galaxy S 4 General] braulio_holtz:
more perfomance http://xdaforums.com/showthread.php?t=2697069
[Galaxy S 4 General] melekbarca:
Yeah i saw that thread before but a lot of users says that there no much difference between ext4 and F2FS in normal usage
[Galaxy S 4 General] melinerunen:
Maybe because in the normal usage we don´t stress the disk too much. Almost all used apps are cached at start up. I think the real benefit will be in increased start up times, creating the art cache, App update/instalation, etc.

Just tried 20150227v2

Very very smooth, except for volume slider (extremely lagged).

Also, it seems like it's not possible to run antutu benchmark, because it will restart due to thermal limit.

In performance settings, CPU settings seems to be gone. I had to add the notification drawer battery mode tile to set performance governor.

Performance mode is very important really, without it chrome scrolling really lags.
[Galaxy S 4 General] sina999:

Audio problem

Recently i switched to frapeti's rom on my S4 and after using I can positively say your rom is better but there is just one problem which is Disappearance of audio (sometimes) , this problem i never faced on frapeti's rom....PLZ FIX!
[Galaxy S 4 General] ruoken:
I can't disable the physical button's lights. When I go to the option in the settings and try to do it, it just goes back to the default configuration (enabled and 5s of duration) when I press "ok". Any help?
[Galaxy S 4 General] Alberto96:
1) I don't accept phrases like this: "PLZ FIX!". Don't be rude.

2) It disappear on every CM ROM (and it happens even on TW ROMs with custom kernels), our audio driver needs more work.

CM Sources bug, wait next build.

I'm pretty sure you already know this, but mirroring the screen via Chromecast or recording with Screencast produces wrong colours.

I'm wondering if you have a fix coming soon.
[Galaxy S 4 General] Duzzar:
Alberto I see you enabled KSM I'm your latest commit. Isn't this a bad idea, considering s4's 2gb of ram still almost never come even close to being used 100% (mine goes around 1gb) and it causes a cpu tax (resulting in slower performance and battery drain)?

Just a thought, of course actual testing is what matters

BTW do you receive donations? I want to drop a few bucks for all the effort

F2FS for System/cache/dalvik? I made system as F2FS from the build which you add F2FS support in gearcm recovery?
[Galaxy S 4 General] Alberto96:
If you read older changelogs you'll see that F2FS support has been enabled only for /data & /cache partitions.
[Galaxy S 4 General] asad007:
Is there a benefit of f2fs ?
[Galaxy S 4 General] melinerunen:
Search in google "f2fs vs ext4"
[Galaxy S 4 General] codybank_789:
On most benchmark, they have data, cache AND system formatted to f2fs.

Now we only have data and cache in f2fs. So we cant refer to those benchmarks for performance improvement on our phone.

/system doesn't need to be benchmarked. Only /data and /cache partitions are used in daily usage (including benchmark apps).
[Galaxy S 4 General] codybank_789:
Correct me if I'm wrong but base on what I read on an xda theard about f2fs, they used system in ext4, data and cache in f2fs and compare it with all of that in f2fs and they got a big improvement. So I think the improvement comes mostly from system partition in f2fs.

not able to access internal storage

Hi friends,

I rooted my s4 i9500 and installed [GearCM][i9500][Q&A][Discussion] Optimized CyanogenMod 12 rom, then i did restored nandroid backup of stock rom using philz touch recovery but now i can not able to download file in dolphin or from whatsapp in simple terms not able to access internal storage. please help me and give a solution. Thanks in advance.
[Galaxy S 4 General] igoa:
Internal Storage? maybe You mean External Storage? (MicroSD)

if so:

SDFix: KitKat Writable MicroSD

https://play.google.com/store/apps/details?id=nextapp.sdfix

use this freeware utility to fix that (REQUIRES ROOT ACCESS)

I did clean install lastest GearCM (8 march 2015 version) and experiencing major slowdown when trying to start a new App. For example ExDialer (custom MIUI style dialer) starting about 5-10 seconds. Phone looks like frozen PC - nothing works and after waiting ExDialer stars. First, second, third attemps are the same BUT then (4+ attempt and so on) starting instantly. Lags even in launcher many times. TB (when restoring Apps one by one) and Lucky Patcher sometimes hangs Up and i have to terminate them from Settings-Applications.

For those people who like i am heavily rely on Call recording i've tested many call recording apps and founded one that works from the line with this build. Search market for freeware "Call Recorder | Boldbeast" and set it up with root and call recording method 21 or 22 (this program known for Lucky Patcher :)

internal storage cannot be accessed

[MENTION=1563064]igoa[/MENTION], it is the internal storage which iam not able to access. When using default stock apps i can use them perfectly like using stock browser i can download and save files but using dolphin browser iam not able to download anything. i cannot able to download media in whatsapp too and same with other apps which uses internal storage.(screenshots attached).maybe the permissions got messed. I tried with fix permissions in twrp recovery but that also didn't help. I tried what you suggested but didn't work out. Pls hlp.

i can download to external memory but not to internal. The error iam getting is "cannot write to specified directory.the directory or partition is read only. "

You flashed cm and then restored a touchwiz nandroid backup over it, it's obviously gonna happen!

After installing a new rom, you do not have to restore a nandroid backup, you need to restore a titanium backup
[Galaxy S 4 General] sasilkanth:
Thanks for your reply.

now what i have to do? do i need to flash again freshly to goback to the stock? how to use the nandroid backup? please suggest me the steps to go back to the stock without any getting any error after flashing like what and all need to be wiped before flashing? and how to use the nandroid backup?
[Galaxy S 4 General] body150165:
I disagree with this. I still see many issues in every day use. See my previous post from yesterday or the day before. Disappointing to see this status of development after this long time.
[Galaxy S 4 General] rgshah3:
See, the nandroid backup needs to be restored when you have an error after flashing a custom rom and need to go back to the original state!

To flash a new rom, format /data /cache and /system

Then install the new rom and the gapps and you are good to go!

Set up your Google account and restore your apps

Please DO NOT restore the nandroid backup

Confirmed. I thought that I was posting in the discussion thread. My mistake. Besides that: Some of the issues occur randomly. I an not sure if it is useful to attach a log of 3 or 4 hours of activity. (Yes, I am not a professional in recording logs). I will remove my post here and insert to discussions.
[Galaxy S 4 General] body150165:
I just switched from CM11 to CM12 with the test build from 7 March and updated to 8March as well as 9 march test builds (Always clean flash). Battery life seems to be improved indeed.

1) It took a while to find out that the previous governors are now kind of hidden. Instead of finding them at settings>performance, I can ONLY access it via status bar quick settings "battery mode". I even have to add this tile in settings. Not sure why it is like this. However, since I changed the battery mode to energy save, the phone runs much cooler than with the default balanced mode. I don't feel any difference performance wise. Having said this, I found a few times already that the battery mode reset itself to " balanced ", even I turned off the default setting " let system decide profile for certain apps". I will monitor this.

2) Regarding toggles: There is no tile to change the network mode (2G/3G). Now it is to be changed within the settings. Annoying.

3) I found that the clock disappears randomly. I have to change the style of the clock (centered or left) then back to right orientation and it's fine again. After this happened a few times, preferably after I turn on the screen, I changed the clock location to "centered", although I don't like this. I will monitor and report. Update: Orientation doesn't have any effect. The clock disappears definitely with every restart.

4) If I change the display of tabs in chrome, the status bar is black and not colored.

5) The status bar color seems to be not working properly anyway. It's disappointing to see that only a fraction of apps support colored status bar. Or is it Android 5?

6) I found that the default system profiles can not be changed? I changed the volume for alarm in silent mode, but the alarm didn't give any sound ( only the pop up). I created a new profile and now alarm works properly. Maybe this might also be affected by the sound bug (see below).

7) The adaptive brightness is crippled and only a switch to turn on and off. In CM11, we were able to customize it in many steps depending on the surrounding brightness. The implementation in CM12 is very much inferior.

8) No possibility to take a screen shot. I know there are apps for that in the play store. But the implemented version in CM11 was much more sophisticated.

9)The notification filter is there. But I can not add a new filter. There is just no button for that.

10) Sound disappearing: randomly, the sound disappears. Completely. No alarm, no media, no call sound. This is a major issue for me. I think that it recovers sometimes after you make a new call (not sure). But what does it help if the alarm doesn't wake you up?

Besides that, I don't understand the hype around Lollipop. I don't see any benefit from the famous improvements. The only benefit that I recognize is the much improved battery life compared to CM11. But this is not enough for me to accept the above trade-offs.

Now I decided to go back to CM11. This ROM is NOT a daily driver for me. I would consider this as an early alpha stage.
