First do you receive any notifications from Greenify that your device is on doze?

http://xdaforums.com/android/apps-games/app-check-doze-support-t3374265

Can you install this app and check doze?

Second can you post a log from BetterBatteryStats?

http://xdaforums.com/showpost.php?p=65025167&postcount=6

From here you can see how to send a proper log.

Third Wi-Fi and Bluetooth scans are off? (Settings-Location-3 dot-Scanning)

Fourth it happens probability because wi-fi is on all the time. Maybe a app which can turn it off when screen is off can help. Also from Wi-Fi settings-Advanced- Click on Keep Wi-Fi while sleeping and select only on charger.
[Galaxy S 4 i9500 Original Android Development] Max Steel:
Voip calls not worked!!!

Please any solution?

Thanks forma the ROM is amazing

VOIP bug

Just play any audio file with your player to activate audio. Then you can make de VOIP call. This information is in the 1st page of that Thread.
[Galaxy S 4 i9500 Original Android Development] LironImaN:
No, sorry. if i remember correctly, i need to format the SD Card for this, so i won't check it for now.
[Galaxy S 4 i9500 Original Android Development] u7Xz:
There are tone of diffrence of Official Lollipop and GearCM Marshmallow. However this ROM isn't still stable there are some bugs and problems which can be solved easy or not. Wi-Fi is one of them. When screen is off it just drains but doesn't happen to me, doze works fine. You should make a clean installmaybe this can fix your problem. Dont forget clean install is always the best...
[Galaxy S 4 i9500 Original Android Development] fariez:
Have you used Gear TWRP recovery? https://www.androidfilehost.com/?fid=24052804347828835
[Galaxy S 4 i9500 Original Android Development] u7Xz:
Yes. Also use Gear Recovery when flashing this ROM. Also your right about your data etc. its hard i know but clean install starts without bugs. You can use Titanium Backup for your apps and their data it can help a lot.
[Galaxy S 4 i9500 Original Android Development] MostaphaHida:
BUGY BUGY ROM not even recommended as a daily driver, firstly flashed running well then starting installing apps and bugs every where , auto reboot the blue led light keeps on and the screen stop responding i prefer cm12.1 all the way.

The lastest build is very smooth and stable for me, no random reboot or lag.

The only bug I feel is the battery drain with wifi, but after flash wifi fix.zip file from melekbarca the problem is gone, still need to test it more further.

[MENTION=2386505]Alberto96[/MENTION] , can you see the wifi fix.zip file from melekbarca to know what changes it makes, cause I think it fix the batttery drain issue with wifi.
[Galaxy S 4 i9500 Original Android Development] Aakash Kaushal:
This ROM is almost perfect but only battery drainage and slow charging are the major issues...

For those who are wondering about GearCM 13 current status, just take a look at this README: https://github.com/GearCM/android_device_samsung_i9500/blob/cm-13.0/README.md

Also, remember that latest public build is this one: https://www.androidfilehost.com/?fid=24566454284189781 (20160526), and i won't provide any changelog because there are no major device specific changes here. Just update your previous build to this one and enjoy.

I'll keep you updated on all future updates, great changes are coming soon, maybe in the next few days if the time allows me to work on it.

Keep following my threads, and my YT Channel (GearLabs, link in my Signature), to stay tuned!
[Galaxy S 4 i9500 Original Android Development] robsonsilva:
I support you [MENTION=5592093]VoLTaqe[/MENTION]. In fact it is currently the only developer to AOSP.

[MENTION=2386505]Alberto96[/MENTION] Why not put your cm13 in TOP FORUM DISCUSSIONS? Least the devices appear s4 i9500 should also there. And you are a big developer within the xda.

Minor bug report.

[Galaxy S 4 i9500 Original Android Development] Bugz1:

[Galaxy S 4 i9500 Original Android Development] rgshah3:
We are a big community if you want help testing
[Galaxy S 4 i9500 Original Android Development] Alberto96:
That's not something i can choose.

OTA Updates app isn't here yet, that's why it crashes.

I know, but i don't have a good internet connection (poor upload speed) so if i should upload every test build it would take ages.
[Galaxy S 4 i9500 Original Android Development] Alberto96:
That's pretty different from his problem. Yours could be just a permission issue with the Power HAL.

Yes, but your Nexus 9 has an Android M bootloader, that could have some differences about offline charging. This is something easily fixable so don't worry about it.
[Galaxy S 4 i9500 Original Android Development] masterlo3:
after running for two days i have to say its been too good for an alpha.. no crashes, smooth ui.. three things that needs to be done is camera, synapse support and some performance tweaks for gaming or 3D..well, about 3D, maybe our gpu isn't as powerful anymore with new games coming out... someone asked for antutu score earlier, sorry i changed my device model to sm-n9000 ignore that cause this test was actually on my gt-i9500.
[Galaxy S 4 i9500 Original Android Development] Alberto96:
Android M uses new OpenGL APIs that we do not support, making the old ones slow.

It's nice to see that you all are enjoying this ALPHA release. I'll mark next one as BETA, but i won't release it if i do not fix anything. Actually there's no need to release new builds just to get Updated CM Sources.
[Galaxy S 4 i9500 Original Android Development] robsonsilva:
No need to rush. Your work is amazing. It is best to wait any longer and have a great build than just a build with errors. And users do not need to hurry because the i9500 will only support android m thanks to you.
[Galaxy S 4 i9500 Original Android Development] SalimPS:
Optimized cm12.1 is performing better that official lollipop .. it's almost the same as cm13..

If you want a bugfree custom AOSP based rom use cm12.1 .. if really wanna use marshmallow stick to this one for now it's still in alpha
[Galaxy S 4 i9500 Original Android Development] Sunjay140:
Thanks, that makes sense. Does this rom support Doze? My battery drained quite a lot last night.
[Galaxy S 4 i9500 Original Android Development] SalimPS:
It should be working but as the developer said it's an Alpha build so maybe Doze is not working yet..
[Galaxy S 4 i9500 Original Android Development] Sunjay140:
Okay, thanks. I'm just happy to finally have marshmallow.

Im having really bad call quality. There is no echo at all, but the incoming voice is very disorted and mixed with lots of noise. Im having nearly full signal strength and good 3g reception.
[Galaxy S 4 i9500 Original Android Development] braulio_holtz:
I believe it is only necessary to include a code

<bool name="config_enableAutoPowerModes">true</bool>

https://github.com/BenzoRom/device_moto_shamu/commit/6c782c3137ef3c28664b70cffa4e15e0099e05fa

This code is not included in the ROM https://github.com/GearCM/android_d...rameworks/base/core/res/res/values/config.xml

The device has to have support SENSOR_TYPE_SIGNIFICANT_MOTION https://source.android.com/devices/tech/power/mgmt.html . I believe that supports (accelerometer)
[Galaxy S 4 i9500 Original Android Development] Alberto96:
SIGNIFICANT_MOTION sensor is a software implementation that uses accellerometer. Luckily Samsung has already implemented it inside our Sensors HAL so expect Doze feature on next builds. :)
[Galaxy S 4 i9500 Original Android Development] musaxci:
Same here!
[Galaxy S 4 i9500 Original Android Development] braulio_holtz:
Thank you, these HAL sensors have the newest devices? because I believe that they will no longer update the S4, I think these sensors are the same in other devices that will be upgraded to Marshmallow... Just curiosity....
[Galaxy S 4 i9500 Original Android Development] Alberto96:
Sincerely i don't know, but Android M supported devices have it for sure. (already supported or with upcoming support)

With Lollipop devices i think you just have to be lucky. Kitkat and older devices can't have it because this kind of sensor has been introduced officially with Android L.

[Galaxy S 4 i9500 Original Android Development] juancruzariatis:
Hi [MENTION=2386505]Alberto96[/MENTION]. First, thanks for your work honestly is a very good ROM.

Well, I'm in the build "20160526" and I presented the following bugs:

• When the phone is locked and off the screen, go into "deep sleep", I think it's a kernel fault, if I remember correctly. I did not try to install another kernel, but then I will.

• When you have plugged headphones when listening to music, and sharing applications or when clicking on the screen, the sound is cut short, and always, unless you already have the application open.

• Returning to the first point, well into "deep sleep", the battery is quickly consumed being in that error. My battery is new, which is not the problem.

"The hard fine, battery has reached me at 4 pm and a few minutes screen. Taking the above, the ROM works perfectly"

Thanks again for your good work.

I hope you can fix those bugs. So we can continue testing, your ROM. Regards!

[Galaxy S 4 i9500 Original Android Development] gp545:
No ETA!

Like mentioned several times here in the thread, no changelog because of time availability is less. If you really want to see what's changed, have an eye on github repository..
[Galaxy S 4 i9500 Original Android Development] SalimPS:
Here is the current status of bugs..

+- Issues with VOIP Calls (due to some standby issue, Audio HAL needs to be fixed)

+- Mixer Paths needs to be entirely reconfigured to get proper audio quality

+- Wi-Fi isn't 100% stable, the issue seems to be on the kernel side

+- Incompatibilities with Snap Camera needs to be fixed (not so important though)

+- Camera isn't 100% stable, there are some issues with ION & v4l2

+- SIM-Card STK Toolkit doesn't work properly, SMSs aren't properly sent (corrupted or something)

+- HDMI Audio isn't 100% stable, sometimes doesn't work, sometimes crashes the device after some minutes

+- SELinux policies aren't ready yet, so the device is running without it until they are properly fixed

Hi brothers! Such build the "Public Test" [20160530] work? All right?
[Galaxy S 4 i9500 Original Android Development] mahosapiens:
Hi everyone! I am using last public build (0530) at two days and it's so smooth, pure cm. I really love it. We can use for daily life. However there is issues too. Like

Battery drain so fast

VoIP calls broken up. I tried with headphones and I and my gf don't hear anything. But when I open the touch voices VoIP calls is being very perfect. I talked 20 minutes and nothing issues happened without headphones.

When I watching a video with headphones voice of videos are going out every 5 or 7 minutes. When I touch video progress bar it be normal.

I had proximity sensor bug in cm12.1 official from but there is no problem about that.

InCall voices be loud or low.

Camera runs very good but sometimes crashing. When you restart phone that issues disappear

When I listening music and lock screen or open screen, then music cut of for 0.5 seconds. It's very noisy but we can ignore it for now.

Other things for daily usage applications run like a cheetah. I think you may use it for our S4. Not warming or freezing. Now my empty ram is 800MB.

Sorry for my English. Have good days!

I can't wait for bugless cm13
[Galaxy S 4 i9500 Original Android Development] LironImaN:
There are weird bugs, even at latest build.

1. Sometimes, even if the device is not in use, it's stuck and won't respond, so you need to remove the battery.

2. Sometimes when switching apps, half of the screen is black, and just when you scroll down its going back to normal.

Everything is good so far in the latest release but charging is damn slow (related to kernel i think), battery drains insanely fast and mobile data is not working in some countries like India,Canada (some reported that its working so maybe it needs some network configuration to work)....rest of the things like camera,music,calls everything works.
