Also I am not receiving sms's :'(

But the rest is just perfect until now

Loving your work, ty ;)

After few days using, I realized this rom is mostly consuming battery. To prove that, I carried out an experiment to contrast battery between HavocOS and Pixel Experience (thx for haridhayal for build), both of them was used RAD Kernel
All test was carried out at spring weather, with 24*C temp.
Wifi and dual-sim are all toggled on, all noti was turned off.
First I played Youtube for 3hrs, then Facebook Video for 2hrs, after that I played Youtube until it shutted down itself. Every 1hr I checked battery percentage and fill the table below. So after that I found Havoc build now are both overheat and battery-drained and hope so for another build

Est-ce qu'il faut avoir la dernière version du twrp pour l'installateur?
le surchauffement c'est dans les jeux uniquement?

@dark1899 Please translate your post to English. Thank you.

le dernier twrp est toujours recommandé, si vous rencontrez une surchauffe, je peux suggérer d'installer le noyau RAD, c'est très rapide, une bonne autonomie de la batterie contrairement au noyau d'origine
Thanks, can you tell me how installing Rad

    I want to share a solution I found regarding banking apps with this rom:
    So I had some trouble using a certain bank app. The app crashes after entering the password for verification. I found out that the connection was successful but the app only crashes after verification. I found lots of workaround implying to hide Magisk and some other tricks but none worked for me. Later on I discovered that the app won't work because of something related to safetynet and also I'm using the vanilla version without any gapps.
    therefore I tried my best to make it the test passes. after many trials and errors, I installed the microg packages(mgs core, fakestore, droidguard helper, framework proxy), then granted permissions for spoof package signature in phone settings, enabled google safetynet in microg setting.
    Now the safety test still fails but somehow my bank app is working.
    I hope that can help someone
    Hi i have old version of this ROM and i came here to check for some updates. It is an excellent ROM btw, works very well for my needs and looks great. Tho now when i look at the versions the newest one is only available with GAPPS and when i want to check if there is at least an update for the old 3.x version that would be vanilla i see that there are only options for Note 8 while my device is S8. I am a bit puzzled by this, in the features there is still written that GAPPS are optional and the ROM is MicroG compatible (which is what i am using) so i want to ask if there is still a way to get the newer version without the GAPPS for the S8 or if there has been some changes.
    Hi, I have already contacted the contributor and apparently their s8 is broken, so they will not be able to provide updates for some time because they can't test them first. I don't know if someone else can generate the vanilla rom from their source code.
    otherwise, the latest version of vanilla havoc-os from 12-2020 is here : https://havoc-os.com/device.html#dreamlte
    Still considering it, lol. I was hoping others could chime in and could maybe convince me lol.
    hey ive rooted my phone and installed hades rom totally worth it man! the battery life and smoothness both have increased, lineageos is real smooth but it has a problem where i cannot turn off 2nd sim in dual sim, so i switched to hades, hades even allows dex mode using hdmi cable

    edit: Secure Folder also works in hades rom, btw its hades pie, Q has too many bugs so i haven't tried

    Shame there's still no vanilla build for n8

    Nowadays is a hard time for me. I'm preparing for passing exams. I don't have enough time to spend on building not needed variants.
    If you wish, you can donate me a server and I will build vanilla on it.
    what's the reason?

    Some people don't want gapps. Will a build be available for Note 8 without gapps?
