Problem is i don't have access to a laptop/pc, i took some logs with syslog app but i can't take last kernel log.Also i don't know which logs have personal information.

The logcat stores which apps are started and running, which apps quit or crashed. It reports network related things, for example that the phone got an IP address from a DNS server, but nothin more "personal". But of course, check what is in the logcat file before you upload it and to do that, a PC or laptop is the best way.

Got another reboot today.I wonder if it's voltage related issue.Could be nice if we had the option to play with voltages.
Voltage controll is colliding with my code. Isnt possible or even needed. I think there is another issue. Try clean flash. Or better give logcat

Try Blokada. That's much better, blocks ads in apps and in browser as well,it has a thread here, on XDA.

Just wondering what's the difference between Blokada Classic origin & origin-slim? What would you recommend?

The original is a bit bigger in size and has 3 different bkocking options while the slim is smaller, 6.3 MB installed and has only one blocking method. I use the slim, added a few apps to the white list (like Gmail, Magisk, etc) and it's incredibly good. Uses 0 (zero) battery and the only app which has sometimes ad is the Fb Messenger.

How can I clean uninstall the sound mod ? I installed them from magisk module. I can delete it from magisk but i dont think it's cleaned.

And why the front camera on video call whatsapp messenger is like the tone colour goes black and normal?

    Android Ice Cold Project

    AICP is known by everyone as the "Ice Cold Project" that started on a Desire HD years ago (2012) and since then evolved into a mature ROM with the BEST community you can find!!!

    Until Lollipop, the Rom has always been based on AOKP. Unfortunately, since AOKP stopped development (but made a comeback later), we changed our base to CM when it comes to hardware, drivers and some features.
    With the rebrand of CM to LineageOS (LAOS) we are now actually LAOS based with some tweaks from AOSP.

    If there are any bugs, either we will sort them out or the LAOS team will if it concerns their code base. This rom isn't LAOS supported, so no need to report errors or bugs to them!!

    #include <std_disclaimer.h>
     * Your warranty is now void.
     * We are not responsible for bricked devices, dead SD cards,
     * thermonuclear war or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at us for messing up your device, we will laugh at you. Hard & a lot.

    We are paying for servers that build nightlies/weeklies and everything that comes with it, so EVERY DONATION will really be appreciated and be used to cover those expenses.
    Thank you!!

    Full Changelog:
    Initial Version

    best Google Apps:


    You tell... :p (only LED Bug i received)​

    Before using the ROM:
    Q. Can I have an ETA for the next build?
    A. Every month when newest Service Patch is availabe.

    Q. Does this ROM support custom kernels?
    A. No. You can still use them (as long as they are LOS based), but discussion should go in the thread of the respective kernel. We don't offer support for bugs you might encounter using them!

    Q. I want to flash Xposed, so which version do I need to install?
    A. Xposed Noutgat ARM64.

    Flashing the ROM:
    Q. What do I need to know before flashing?
    A. Check the install instructions in the first post...

    Q. Can the builds be dirty flashed over each other?
    A. Yes, however make a nandroid first as there is a chance of getting a bootloop or encountering bugs. Also bugs may only be reported on a clean flash.

    Q. How do I dirty flash builds?
    A. Wipe System, Cache and ART/Dalvik cache. Flash the ROM, your preferred root solution and reboot. Or you might just use the OTA app to preform that task for you.

    Using the ROM:
    Q. How do I enable software buttons?
    A. Settings -> Navigation -> Enable navigation bar. The bar can be configured separately in its settings.

    Q I installed a bad theme and now I'm getting a bootloop, how do I fix it?
    A In TWRP, flash the substratum rescue zip in the substratum folder on the internal storage.

    Q I keep losing root with Magisk, how do I fix it?
    A Check this out, if that doesn't work for you ask for help in this thread, read or ask in the Magisk thread on XDA or just flash Magisk again!

    Q I'm having issues with WhatsApp, how do I fix it?
    A Read this

    Q. Do I need to provide a logcat if I'm reporting a bug?
    A. If you want it to be fixed faster (or at all) then yes, you should definitely provide a logcat. (Note: Please just link the logcat from your GDrive, Dropbox, etc. and do not post the content here. Thanks.

    Q. How do I get a logcat, what type should I get and more questions that can conveniently be answered by my pre-determined answer?
    A1. Read this thoroughly. Also, here's a good app for getting logs:
    A2. If you are already rooted, you can use the built-in feature to make a logcat and provide that. Just look into the root section in the AICP Extras menu.


    The ROM should contain everything you need to enjoy Android Nougat . You don't need to install any Add-Ons, simply download the latest ROM, GApps, flash it and go!
    If you want the device to run the ROM "rooted", you can flash a root solution of your choice after the ROM Zipfile.

    It is STRONGLY recommended to fully wipe your device before flashing, and if possible avoid restoring system apps and system data with Titanium Backup as this can cause stability issues that are very hard to debug.
    If you believe you know what you're doing - then fine, go ahead, but please don't complain if you experience any strange behavior.
    How to flash:
    (Again: Don't do it if you don't know it!)

    1. Download the ROM and GApps and transfer them to your device
    2. Boot to recovery (TWRP recommended)
    3. Wipe system, Cache, data and ART/Dalvik cache
    4. Flash ROM Zipfile
    5. Flash/Install GApps (optional, needed for e.g. Google Playstore to work)
    6. Flash/Install the root solution of choice (optional)
    7. Reboot to system

    The ROM has GApps persistance in between dirty flashes, so you only have to flash them once!
    The root solution should be flashed together with every OTA update (= ROM Update)!

    Supported Root Solutions:


    Im not planing to work on a OTA App, but if i get enough response i will think about it so its all about you!.
