Try other stock roms, not aosp as suggested by dobrun.franjo
If camera still don't work on stock rom, then obviously you have hardware problem, you should take it for repair

Well, that would not have thought. Seriously. When set to the lowest level, the call volume is too loud during the call. So I asked which file to modify, so that the lowest volume is quieter.

I'm sorry, I did not mean to insult your intelligence. I just stated the method that works for me, however simple it is. As for the modification you are looking to make, I can not help you with that, sorry, but I don't know that much about Android.

    Hi @marchetto96, do you have in mind to keep updating the rom?
    I only want to know it to wait for the update or to flash your new RR. I feel that Viper works a bit better in my phone.
    Thanks so much for your work!

    Yes, It will update. Next version v3.0. #StayTuned.
    Stock is the best :good:

    I think it isn't best :)
    Battery life is so bad. It is still draining.
    I need a rom that it has got good battery life

    For this phone never will exist a good battery life... NEVER! :p
    Believe slacker, i have take long time to test all kernels as possible.
    At beginning the lg devs have works hard on their android phones, they have habbits of their devices.

    I don't say that kernels devs (especialy on XDA) don't know how to build great kernels but they aren't the lg devs.
    We know that d855 and variants haven't got good battery life and overheating problem, it's not a surprise.
    We can add xposed/magisk support on certains android versions/ROMs but more you add hooks stuff at each android tasks, more the phone will be burn, it's logic.

    Between all that, we can find the best middle :highfive:.
