Hello! Longtime Android user here.

I am currently using LineageOS 21 on my Pixel 7 Pro, however after rooting and running a few Magisk modules I have been having issues with overheating.

So what I planned to do is build LineageOS myself, and use a custom kernel.

One of these:

Some follow up questions:

  • Will this break using banking apps because of custom kernel? (even with Chiteroman’s PIF, Zygisk, and Shamiko?)

  • However, I am unsure if I build LineageOS 21 with one of these custom kernels if I will be required to build each update with the custom kernel, or if the updater would update my build.

I am open to suggestions on how to solve my thermal issues if anyone has any.

Thank you!

Edit: more questions

    It’s been a while since I used custom android kernels or even LineageOS (last used it on my Mi A1), but regarding this point:

    However, I am unsure if I build LineageOS 21 with one of these custom kernels if I will be required to build each update with the custom kernel, or if the updater would update my build.

    I believe you will need to stick to the kernel branch that you are on (i.e. wait for the maintainer to push out a new kernel), I don’t think there will be any automatic patching that would account for kernel customization.

    Apologies if I behind times and I made a mistake regarding the point above. :)

    I know you didn’t ask for alternatives, but since you have a Pixel I thought I’d at least mention it.

    Have you tried GrapheneOS?

    My battery life is amazing with it and I’ve never had any overheating issues.

    Edit: my local credit union app works fine. You can even relock the bootloader after you install graphene.

      Thank you for the suggestion! However, I have used GrapheneOS. And I am a fan, and it could absolutely fulfil most of my needs. However there are a few things that it can’t accomplish for me unfortunately.

      There are Magisk Modules I use that I couldn’t get loaded on GrapheneOS without massive hassle. I also don’t want to live without AdAway, App Manager,Pixel IMS, AFWall+, amongst other apps.

      I ran GrapheneOS before they supported Android Auto, and for a while after they had put that in. I just don’t think it would exactly fit my current wants and needs.

      As far as AdAway I totally understand that I could use a local VPN service to accomplish similar and block ads that way, however that would take away from my ability to connect to my home network and block ads.

      I know my use case is rather fringe.
