with last update i have problems with youtube videos, videos from facebook, camera not working. hw decoding not working!
[Samsung Galaxy Nexus] Codename89:
Data cleared, but camera still doesn't work :(
[Samsung Galaxy Nexus] blystad:
Could be play services, but it could also be that disabling SMC (and freeing up 3MB) made the device struggle with getting into power save mode. I see a lot of l4 interconnect references in the kernel message log (not sure if it's normal on Galaxy Nexus).

The L4 interconnect connects the ARM processor with the crypto module (used for AES, SHA and other related things) (CD_L4_SEC).

Ziyan should be able to diagnose this using the omapconf tool and check if there is an active dependency to L4SEC ( omapconf show prcm statdep ).
[Samsung Galaxy Nexus] Polooo2:
I am having the same issue. But since 0207 build, a update to 0212 didnt help much. Sometimes it freezes during boot
[Samsung Galaxy Nexus] Fenvarien:
With the latest build my GNex is running absolutely stable. No freezes, no reboots. Just the camera has it's hiccups now and then, but clearing the camera apps data helps for a while. Did those of you with reboots and freezes try a clean flash or did you just dirty flash from an older build?
[Samsung Galaxy Nexus] AgusL:
Dirty flash. I have to try clean install and also will try CM13 as well.
[Samsung Galaxy Nexus] hgmichna:
Camera problems

Please try another camera. There are many, but the two major contenders are the "built-in" Cyanogen camera and the Google Camera.

And if you report a camera problem, please state which camera it is.
[Samsung Galaxy Nexus] SickMF1:
Can I install Cm 12.1 considering that the phone rooted stock 4.3 and

Franco kernel

? Stock 4.3 is not a problem , I ask this because of the

kernel

.

If not so , then what should I do and in what order? Thanks in advance.
[Samsung Galaxy Nexus] ancelin:
First you need to have twrp recovery. (If you are root flash it from your phone with this apps Rashs)

Then wipe + flash rom + pico gapps (kernel will be updated)

My device is really smooth than never, no reboot, no battery issue and working camera.

What am i running for now :

I flashed 12/02/16 build with boot.img from 10/02/016 with 20160120 pico opengapps to avoid 963 play store issue
[Samsung Galaxy Nexus] Polooo2:
I did a dirty flash ... will try a clean flash
[Samsung Galaxy Nexus] goblin999:
I've done a "dirty" flash, and it has been running well since Sunday. But the phone has rebooted today, and the CM camera app doesn't work. It keeps saying that it can't connect to the camera and I allready cleaned the app.... I'll tey a differwnt app...
[Samsung Galaxy Nexus] momojuro:
Of course that you can, the installation process of the ROM will erase your previous installed kernel so don't worry about. Concerning what you should do, read the following post from [MENTION=2568520]ancelin[/MENTION] :) :

Best regards.
[Samsung Galaxy Nexus] galexmvs:
Where can I download boot.img from 10/02/016 ? I can't search it :confused:
[Samsung Galaxy Nexus] hgmichna:
I'm surprised you use the pico version. On my slightly older ROM build I used OpenGapps nano, which has all the functions not available from the Play Store. Is that no longer possible with the latest builds? The pico Gapps lack some functions.
[Samsung Galaxy Nexus] ancelin:
Just download the 10/02/16 rom version and open the zip (with 7zip) to copy the boot.img (on desktop for exemple), then open the 12/02/16 build (with 7zip) to add the previous boot.img (erase it)

Ps : I haven't test yet the last 20160216-NIGHTLY, may be it correct things? anyone have a return about last build?

---------- Post added at 09:03 PM ---------- Previous post was at 08:58 PM ----------

Nano didn't work before on the build .But what is missing for you? You can download every thing from play store.

New built take the nano version apparently, I will have a try next time.

[Samsung Galaxy Nexus] nickpj:
Just upgraded a galaxy nexus maguro to cm-12.1-20160216-NIGHTLY from 20160212-nightly and KitKat/4.4 before that, looks good but a few glitches observed:

* Camera, using the standard CM camera app, get "Can't connect to the camera" error sometimes, works other times. Understand that this should be fixed in next nightly, yay!

* Can't receive MMSes. Shows the message size and expiry date, says "Download" or "Downloading", but gets stuck there and does not load the image or message. I've set just one MMS APN (deleting all the others), but it's still not working, and that one APN is set as per the carrier's suggested APN configuration at: https://www.amaysim.com.au/help-sup...et-up-mms-settings-for-my-Android-device.html

* Under the quick tiles, it should show the carrier's name (Amaysim), but instead it shows "Emergency calls only". The mobile signal in this area is quite weak, so probably starts as emergency only, but does acquire a signal shortly thereafter. Verified that I have a signal by calling from another number, and it rings okay. So possibly this quick tile is not updating?

* Google maps not really working properly for navigation - would show the route, but did not seem to update the position as I drove. This happened on 20160212, have not verified yet with 20160216, but would assume it's still there.

In all other respects, looks good! And it's great to be able to get 5.1 on this device.

I can confirm disabling SMC caused battery drain (if no other recent cm commit fixed something else, what caused it).

I reverted 'tuna: disable SMC' commit, created a build, flashed it and my battery consumption is back to normal.

I am still experiencing this issue :( I hope it gets sorted out someday.

In my humble opinion CM 12.1 in its current status is better than Jelly Bean 4.3 (which is old and outdated). Kudos to people who brought us Lollipop :)
[Samsung Galaxy Nexus] Ziyan:
I still think it's something else. I've been using non-smc builds since a while, and getting ~10% battery drain overnight.
[Samsung Galaxy Nexus] ancelin:
[MENTION=2633638]Ziyan[/MENTION] you should update top first post to konw issue and how to fix it :

- If MMS issue --> only use one Data APN with MMSC set and ",mms" on APN type...

- If error 963 on play store --> to use 20160120 opengapps

- any other tip to fix issue?
[Samsung Galaxy Nexus] Zenroid:
How about in comparison with CM11? I am using it happily with greenify without xposed enabled and it has been so stable and fast enough in most occasion

I also installed an auto WiFi on/off app and the battery drain is less than 1% per hour in bbs though I never use data just wifi

Actually I flashed the cm12 earlier before but could not be booted up possibly to my cwm recovery that's why I reverted back to cm11 and flashed twrp

The only thing missing is ART as I tried in on cm11 and it was awfully slow

After having tried earlier Nightly's, I have installed this Nightly on my Galaxy Nexus today. It works beautifully! All apps that I used with CM-11 are installed and working. No complaints at all. Have decided to keepCM-12.1 on my phone for day-to-day usage.

All your efforts are greatly appreciated!

[Samsung Galaxy Nexus] Ziyan:
The next nightly (should be up by tomorrow) will have another approach of RAM reclamation merged: instead of reducing the ducati iobufs carveout size, this one makes the tiler carveout (used by ducati for camera and video stuff) dynamic instead of fixed. This results in about 42 MB of RAM freed up when camera is not running (resulting in 819 MB userspace RAM). The best thing of this is that it actually increases camera stability, as the carveout size doesn't have a limit now.
[Samsung Galaxy Nexus] handofdark:
awesome!!! great work
[Samsung Galaxy Nexus] nikodr:
[MENTION=2633638]Ziyan[/MENTION] would you post this new kernel for cm 13. The one you said about 819mbytes user ran and improved camera. Woukd love to have it on cm 13

Which camera?

I guess this is the 2016-02-20 version I am installing. Incredibly great progress!

One question: Does the dynamic camera RAM work only with the Cyanogen camera or also with the Google Camera or with any camera?
[Samsung Galaxy Nexus] netreign:
with last update i have less free ram and camera doesn't work!
[Samsung Galaxy Nexus] pluk64:
I repo synced (smc left disabled) and battery drain is back.

Just informing about the results of my A/B testing, don't trying to make any conclusions, since I know nothing about smc.

(Also, my testing was not the most correct - cos I repo synced - but still it could have some value)

Google Camera - I'm getting can't connect to camera error in following scenario:

1. Open camera

2. Press home button

3. Open camera again

( I'm just dirty flashing)
[Samsung Galaxy Nexus] Fenvarien:
Yes, the 2016-2-20 build is working very well and the additional RAM helps quite a lot.

I'm using Open Camera app and it's working stable without any issues. The "camera is not connected" problem seems to be resolved! :)
[Samsung Galaxy Nexus] Ziyan:
It works with anything that needs tiler allocations (cameras, video players, encoders).

Odd, I was able to reproduce this. Did you notice it in older nightlies (from before 20160210) as well? I don't really think it's related to the dynamic tiler allocations, but I'll have a check (it seems to be a userspace problem).

About SMC, our anonymous developer said that disabling it might indeed cause a battery drain - while I never noticed it, I believe him and the other users here, so it's re-enabled in todays nightly already.
[Samsung Galaxy Nexus] pluk64:
I'm not using camera a lot so I cannot remember exact time, but when I was checking pink lines workaround (20160210), I didn't notice any problem.
[Samsung Galaxy Nexus] hgmichna:
Camera after closing it with the home button

Happens with the Cyanogen camera as well, but I guess it is very similar to the Google Camera.

It does not always happen. I just had it with the Cyanogen camera, then I opened the Google Camera, and that still worked. But later I had the Google Camera also failing. Seems to be a bit weird.
[Samsung Galaxy Nexus] Codename89:
Camera still cannot connect for me, with the latest nightly (20160220)

[Samsung Galaxy Nexus] playitlouder:
Does anybody know, why the latest TWRP (2.8.7.0) doesn't offer F2FS, if I want to change the file system of /cache?

I thought F2FS might result in a slight IO boost, when used on cache (didn't want to format /data right now).
[Samsung Galaxy Nexus] :
The /cache partition is used mainly for downloading files from Google Play. It doesn't really matter whether it's EXT4 or F2FS. Your apps' cache is located on /data anyway.
[Samsung Galaxy Nexus] playitlouder:
Thanks for clarification!

But it's not showing up on data either ;)

Thanks [MENTION=2633638]Ziyan[/MENTION] for the memory optimizations. The phone feels nice and responsive.

Does this rom is complatible with F2FS? if yes on what partitions?
[Samsung Galaxy Nexus] beatles1:
Hello guys,

So I am facing the 963 market error. Found the solution of using the 20160120 opengapps (https://github.com/opengapps/arm/releases/tag/20160120).

I had installed the Gapps from http://opengapps.org/?api=5.1&variant=nano

Now I want to uninstall those and install the 20160120 ones. Do I have to perform a full wipe of the system or I can just flash the new gapps over the old ones?
[Samsung Galaxy Nexus] Fenvarien:
This doesn't happen for me if I try to reproduce. I'm using the Open Camera app and did a clean flash for the latest build.
[Samsung Galaxy Nexus] playitlouder:
Wipe /system only, install Rom, install Gapps.

You will not loose any data.

I experience the camera crash on the latest build without a clean flash, too.
[Samsung Galaxy Nexus] beatles1:
Thanks a lot! +1 for the camera crash on the latest build
[Samsung Galaxy Nexus] Insider7:
Hi Everyone,

I completely don'n understand why I cannot install gapps after formatting /system.

[Samsung Galaxy Nexus] hgmichna:
Check for updates - Weekly, Monthly

Here is a little nagging thing that people complain about in my vicinity. When you set Check for updates to Weekly or Monthly, the setting is ignored. It seems to always check daily.

It is a minor thing, but perhaps it is also a minor act to fix it.
[Samsung Galaxy Nexus] ancelin:
Did you installed rom first, then Gapps?
[Samsung Galaxy Nexus] hgmichna:
Ho to flash CM and gapps

Let's restate what exactly you did. I think you should have TWRP 2.8.7.0 installed and use it to

wipe system,

flash the latest CM nightly for your phone type, like maguro,

flash OpenGapps nano for the ARM processor.

TWRP can flash both CM and gapps in one go, which is OK, as long as you flash CM first.

Check whether your downloads are good. Perhaps you have a crippled download.

[Samsung Galaxy Nexus] hgmichna:
Root/Recovery

Wrong sequence. Flash TWRP, then flash a rooted ROM. Then your phone is rooted.

To put it differently, you don't need to root to flash the TWRP recovery. You could say that a powerful recovery always has root rights.
[Samsung Galaxy Nexus] vortex-5:
Also getting cannot connect to camera on 02-20 -2016 nightly.
[Samsung Galaxy Nexus] gnexus2012:
hi,

I can confirm that camera has still problems connecting on 20/02/2016 nightly. The ROM comes with a ~795mb ram kernel moreover. Where is the ~840mb kernel Ziyan talked about that is dynamic and fixes camera probably? Im using the 802mb custom kernel right now.

Thanks
[Samsung Galaxy Nexus] LeoHart:
I think it is a RAM issue.

If you have an App with heavy RAM usage (e.g. Browser) in background and you start the Camera, it occurs an Error.

Close the App and start the Camera again. It can take some seconds until Andoird clear the RAM space.
[Samsung Galaxy Nexus] norton75:
I noted the same behavior; it seems like camera app assume that the camera should respond immediately when accessed and if the driver requires some time to load (because now it is dynamically allocated) it returns unable to connect. Maybe a little sleep could be enough to solve?
[Samsung Galaxy Nexus] hgmichna:
Interesting thought. However, the browser should be removed from RAM when another app needs more RAM. In fact, Android forcibly halts and removes even running apps that are actually doing something in the background when there is not enough RAM for another app to open.

But perhaps the new dynamic RAM allocation for the camera does not work as well as we hope. Perhaps the original arrangement (fixed RAM assignment for the camera) was there because the programmer wanted the camera to start very quickly. I can only guess.

Appreciation of cm-12.1-20160220-NGHTLY

I'm using the last few nightly's for over a week now, and cannot conclude otherwise than that the present nightly functions extremely satisfactorily, and is - in my humble opinion - very stable. I don't experience any problems in using the camera.

I only have one small remark, but that is probably a characteristic of Android 5.1.1. When I'm using the phone, and select "all contacts", I do indeed get all contacts (from the "Contacts" app), while in Android 4.4.4 I only got a subset of the contacts in the "Persons" app: only contacts with a telephone number. A minor item, though.

All-in-all, I'm extremely happy with CM-12.1. I was afraid that the battery-drain might prove to be larger than using CM-11, but I have the impressions that the contrary is true, while CM-12.1/Android 5.1.1 also provides more possibilities to control battery-drain.

Maybe these are all known facts for the experienced user, but I'm a new user of smartphones: I started using my Galaxy Nexus (a left-over of one of my sons) last December. Therefore my apologies...
[Samsung Galaxy Nexus] hgmichna:
Battery drain

There is one setting that seems to have some effect on energy use:

Settings, Battery, Enable per-app profiles​

I believe battery use is lower when this is enabled, and I'm not sure whether it is enabled by default.

Nobody knows what exactly it means. It is particularly unclear what the downside is to having it enabled. After all, if there were no downside, then the setting would be superfluous. I have the vague suspicion that background apps get killed more easily, but I have no good evidence.
[Samsung Galaxy Nexus] Childe89:
This setting should enable automatic changing of governor - if requested by app, for example if you run a game, phone will run in "performance" mode with no underclocking.

Basically it switches between battery profiles, no idea if it changes something else except governor.

other major issue on CM 12

Except camera issue I have noticed 1 more major problem. If roaming data is OFF and you go abroad and switch ON roaming data - nothing happens. Even if you restart, no way to get mobile internet working in roaming. If you leave origin country with roaming data ON - 3G is working correctly in roaming. After that if yo switch roaming data OFF and ON - it is working again. But if you switch roaming data OFF, restart your phone and switch roaming data ON again - 3G is not working and you can't get it working until you go to your origin gsm operator and leave your origin country with data roaming switched to ON. It took me 3 weeks to get these details. I hope that this information will be helpfull to somebody.

I don't think the commit http://review.cyanogenmod.org/#/c/132375/ is responsible of camera issue. This is only a switch from debug mode of a camera component.
