    Thanks Nova,, Downloading……….

  • Carlos says:

    how i install if a have a previous version? i need any wipe?? or just install from recovery?

    • Kevin says:

      Download an aplication called Cyandelta from play store, place the archive of the new version in your internal memory and then use the aplication from installing it, it’s really easy and fast, if you have any trouble with that tell me, that’s the way I install it.

    • mirko8054 says:

      Enter to TWRP, wipe cache and just flash the rom.

  • Alejandro says:

    Hi! Sorry for the ignorance, but …. What’s Torch?

  • theride says:

    My photos don’t load in the Gallery app, they are here, but they are grey.
    Thanks for your work.

  • norman says:

    Can someone answer my query? Is the SIM on this ROM working well?

  • LIlo says:

    Thank for your work in all case.

  • Jakir says:

    Now the problem is that we cannot turn off the torch.

  • vope says:

    Great work !

    As requested in the topic, here are my bugs

    – Bad French layouts
    – Bad French translation due to Cyanogenmod
    – BLN Control doesn’t work, due to Novafusion kernel, apparently
    – Still torch Long on-time.
    – Still torch crashes when toggle several times… then it reboots, and I must reboot again because simcard is not activated
    – No EAP-SIM
    – Sometimes when I turn on the screen, the touch doesn’t work.
    – Battery drains so fast !
    – slower than 20150523 release

    other comments :
    – for previous release, when the phone is off and on-charge, impossible to launch TWRP
    – I didn’t test off-line charge.

    To Nova Team:
    – could you update the link to download GAPPS, please ? It is broken…
    – could you update TWRP to ?

    • grostim says:

      J’ai la nette impression que le dev ne lit jamais les commentaires…
      J’en viens même à penser que d’une release à l’autre , il ne change rien… Son seul but est de générer du traffic ici ; donc des revenus publicitaires.

  • Robbe says:

    Thanks again Nova for the new ROM:
    1-this ROM recognizes the SIM faster than previous ROMs
    2-battery is draining very very fast.
    3-cpu stays long time on 1000 MHz. I have tried to reboot few times to see if this condition goes away but negative.
    4-not able to test more due to battery drainage.
    Thanks anyway. Keep the good work

    • hasseos says:

      Try turning wifi off, then reboot, it should be fixed. at least thats what i do

      • Kevin says:

        I know what is the problem. It’s just simple an app that drains the battery so fast. The app is called cLock, I think is the clock of the system. If you want to stop it draining the battery, just go to privacity permissions settings and turn off the permissions for this app, I tried it, and it works very well. My battery is 60% better. Turn off all permissions, as keep the phone on, and on it automaticly, etc… And you also can use Greenify, wich is a very good app for keep a good work of the battery, that’s what I use!

      • Robbe says:

        Thanks hasseos. It happened with the wifi off. I went back to 05/23 Rom for the moment.
        Thanks again for your suggestion, keep up 🙂

    • T3seR says:

      Trie change CPU governator to zzmove and escalator I/O do CQF

      • Robbe says:

        I will, thaks for the suggestions.
        T3seR how is the battery duration with that combination in your case?
        Did you see any improvement?

        • T3seR says:

          With 3G on my battery duration is 10 to 11 hours, without 3G 24 to 26 hours.. with music sms and call’s

          • Robbe says:

            I did what you said and in 3G I get merelly 8 hours, with the same apps that with CM11 I was getting at least 10

  • carlosortiz92 says:

    An alternative camera? Camu It does not work well

  • Kevin says:

  • Dario says:

    Sistem UI crashed

  • Robbe says:

  • christian says:

    very strange

  • jimbo says:

    great work but ; – instagram video crash and stopped
    – power-saving shortcut does not work
    – torch Long on-time
    – self-reset
    – sometimes those screen disappears when I returned to the main screen

  • T0mAs says:

    Perfect work, thank you Nova.
    Althrought, im not able to use F2FS file system with any of the 12.1 release. I tried to format it to F2FS, but after installing ROM it changes back to EXT4. I dont know how to proceed. Any idea? Thank You!!

    • Robbe says:

      Tomas for the moment system is in EXT4, I have asked the same question few times with no answer what so ever.
      Remember this is a nighty ROM that we test, with our imput Nova makes charges, there’s must be a logical reason in the programming part of that section.

  • Robbe says:

    There’s a new update in play store of Facebook that this ROM does not let to finish to install

  • Hugo says:

    I got some lag while opening the dialer keyboard, bug while playing videos on browser in window mode( video do not appear, just works in fullscreen mode), lag while changing music. Thanks nova, great work!

  • Angelo says:

    Instagram YouTube are always crashing. Battery drains Faster. Torch is slow to Open. Random Reboots. And Please remove those unnecessary Features. Offline Charging Animation is Not AOSP.

  • zibos says:

    Please enable OTG again

  • Thiago says:

    The developer options, you guys think the option to upgrade the recovery of Cyanogen should be active or not?

    • T3seR says:

      recovery from CM? I think all contents of ota is off…

      • Luiggo says:

        I used that option once and when flashing a new rom my phone crashed and not even TWRP was working.

      • Thiago says:

        According to the description it replaces the current version of recovery by the included version of the ROM to be installed.

    • Robbe says:

      I tried that and thanks god I had a backup of my installation, my cell did not want to start anymore and I had to flash by ODIN the TWRP 2.8.0 and restore the backedup file.

  • Kevin says:

    Guys! What I can study at university
    to learn about this. 😀

  • miche_ita says:

    Help please
    i install the twrp with odin and all is well.
    After reboot I can’t log in anymore in twrp (with the key sequesza, ne with advanced restart), the phone always crashes after the logo on a black screen every time I reinstall the recovery

  • Ridha says:

    I really like your efforts but why your system is still crashing cm11 is more stable

  • felix says:

    Facebook and other updates don’t finish it freezes in “installing”

  • CprCtrlFreak says:

    Google Play stopped working.

  • Nicolas says:

    i can’t find the users feature, does this rom support it?

    p.d: the Open Camera App in the play store takes perfect videos in my case, is fully working

  • San Nguyen says:

    Random crashes and reboot. Fix it. Please….

  • Sankar says:

    Would you be developing Android M for S3 Mini too? Thanks for you support so far, Team Nova 😀

  • Anthony says:

    The rom seems to be stable, no crash until now, battery duration is pretty normal. Video recording doesn’t work properly (green video still persist).

  • cat5000387 says:

    Excellent firmware, the current problem is the rapid discharge of the battery.
    And still add support for OTG please!
    Thank you!

  • Sankar says:

    Would you be developing Android M for S3 Mini? Appreciate your work Team Nova!

  • Pieter W says:

    I installed Carbon 4.4.4 yesterday, and it seems a common issue with a lot of ROM’s is that they can’t upload video’s to Instagram etc. I can’t upload video’s to Messenger either, or send video’s on snapchat (I can vid them, just can’t send them). Does anyone know how to fix this?

  • Robbe says:

    Good morning guys, the screen freezes many time and the only way to be able to make any choice is to to push shortly the power button so the screen turns off and only than the cell starts to work again.
    It is not a big issue but it bothers when you are trying to text to somebody with whatsapp or with any mail app.
    Battery really runs out quite fast. I hope you can find out what it is causing it.
    Thanks again Nova you are doing a marvelous job, keep up 🙂

  • Fernando says:

    Great work team nova
    My bugs:
    1. Instagram, facebook video and youtube random crashes
    2. Randoms reboots when the device is saturated

  • Kleon G. says:

    Here my bugs:

    At first attempt facebook and twitter didn’t work, then I decided to uninstall “goolge now” and “google play service” upgrades. After this I reinstalled FB and Twitter and updated “google now” and “google play service”. After this procedure, everything works well.

    Video doesn’t work: green video still persist.

    CamU app doesn’t work properly: too many lags.

    I tried others video app, but they recorded video only in low resolution.

    No reboot, the system seems to be stable.

    Battery Drain too fast compared with stock rom (2 days of duration).

    FM radio app doesn’t exist.

    Dialer too slow on starting.

  • Gary L says:

    using 20150527 at the moment – it’s good at the moment. Real shame that the camera doesn’t work for video – any ideas why that is?

    All in all it’s great work.

  • Dennis says:

    Thanks for the new release.
    Here are my bugs:
    – Facebook crashes when a video preview is loading
    – Battery drain
    – Dialer crashes when I get an incoming call

  • Angelo says:

    Android M is Out but the Camera in these roms are aren’t fix.

  • Sanued says:

    Hello guys,
    I would like to ask you, how did you root this phone with CM12.0 (or CM12.1). With CM11 I used VROOT, now called iROOT(some chinese product) and it worked good. But it is not working with CM12.0. There are some apps that I need in my phone, but they request root.

    Can you help me?

  • amb67 says:

    Great work, few issues are:

    Random reboots, even when no one actually touches the phone, did it whilst sat on my desk at work.
    FaceBook, Instagram, Linked In all shutdown after a few minutes browsing.

    Incoming call volume still very low, hitting the volume down then up button doesn’t work.

    Battery drains really fast, 7.00am – 17.00hrs, very light usage, 89% drained.

  • webwiller says:

    In the shutdown sub-menu, if I chooose “reboot in recovery” the mobile tries to reboot unsuccesfully and it is impossible to reboot it again. Cannot reboot it even in recovery using std buttons combo, it does NOT work at all. The only way to get the phone back at work is to flash recovery through Odin.

    With this version I cannot connect to my home wi-fi. It sees and recognize the net but it just saves it and when I choose “connect” it seems just like ignoring the cmd.

    Battery drains very fast even with black wallpaper and little to no usage.

    Maybe it’d be the case to remove “f2fs support” from the list in the Rom description as it’s confusing and people keep asking why they cant get LP working with f2fs while it doesn’t: it works on ext4 by now.

    These are my bugs/concerns, thanks for the Great work Nova! 😉

    • michelangelo says:

      me too one problem of your

  • omri says:

    I found a MAJOR bug where I can’t install updates for app from the AppStore.
    Can’t update Facebook app and after trying to reinstall it, I now can’t install it at all!
    Also can’t install update for AppStore itself!

    hope they will fix it soon!

  • yodaofborg says:

    Apps will not move to sd, even though this is fixed on some cyanogen mods, it is not on this one.

  • nikolas says:

    Hi, the Open Camera app in the play store works perfect for me, better than Camu app

  • Boris says:

    Is there option for make screenshot like in original S3 rom by pressing HOME+POWER buttons togetger.. i tried it but not work.

    can you integrate it?

    keep up good work!

  • Nice work, thanks!
    But the gapps link is sending to a closed thread on XDA, can you fix it?

    Thank you!

  • maqifrnswa says:

    As always, thank you for your work!

    Updated from CM11. After update, apps that used to be installed on my external SD card have disappeared, and you can no longer install (or move) apps to the external SD card.

    I don’t know why google doesn’t let up use external SD cards… you can’t even set their own camera to save there… So now my internal is full and my external is empty and I don’t know what to do (not CM or nova’s issue, just an android one)

    • Robbe says:

      Just a suggestion. If you kept a backup of your CM11 installation, I suggest you to reinstall the backup, after that move back all your apps from your SD to your internal memory. Sincronize with play store. Try again to install CM 12.1. Don’t wipe internal memory. Install gapps for 5.1 and when you finally will restart your cell and connect againg to play store little by little all your apps will start to download. Sometimes not all the apps you will find in the change. You have to manually download them. It’s part of the game 🙂

  • fix the camera,i just want this,using cm11 now

  • Nindroid says:

    Hi, my device is an s3 mini gt i8190 and i am trying to install cm12.1……I did all the steps exactly as they said and after the rom finished flashing i tried to go to the recovery mode to perform the wipe but i couldnt go to recovery mode using vol up+home+power buttons and my phone was stuck at the cm logo screen. But after some time the phone itself started with all my old apps and data . the cm 12.1 rom was working properly but all my apps were behaving strangely so i tried to factory reset it .After the reset my phone my phone now only boots to the twrp logo which says “teamwin” and it flickers after some seconds but stays stuck there . i have also tried reflashing the rom but after flashing it 3 more times it still shows the twrp logo. And i still cant go to recovery mode . please guys tell me what should i do!!!!
    Thanks in advance

  • Rom is too unstable to use it, even i9100 got stable CM12.1 ((

  • Ahtoa says:

    Wifi not working on 5Ghz band. I got S4 Mini (I9195) and it can connect to the 5Ghz AP just fine. S3 Mini (I8190) can’t see that AP. It can only see AP when I switch over to 2,4Ghz band in router. Which is under heavy interference and not really useful. By specs, S3 Mini should be 802.11abgn capable device.

  • Mihkel says:

    Thanks for the shiny Lollipop;

    but STK (SIM Toolkit application on SIM card is not working in this CM12.1 anymore, looks like perhaps unable to send out SMS reply.
    Was working fine on the same phone with CM11 previously.
    (btw: the same STK application on the same SIM card is working fine in “real S3” i9300 device with another unofficial CM12.1 rom!)

    How to debug/test (and/or provide more information)?

    does this work on s3 mini sm-g730w8

    Alarm (clock) and timer sound is muted. Phone only vibrates but no sound I can hear. Other sounds work fine. I have tried Timer application and also original Clock application.
