Due to requests from some users I added signature spoofing support to the rom which allows usage of MicroG
you can simply install MinMicroG and grant it needed permissions for signature spoofing to make it work as intended
Based On Android 11/R

I noticed lack of real development on 8895 device and had some extra time, so here we go, expect more progress happening and bug fixes (source will also be released soon)

One thing I noticed overnight, before going to bed the battery percentage was 51% and when I woke up it was 48% which is something I have never seen on my phone, usually, it was around a 10 to 15 drop. But within 5 minutes or so the battery droped to 37%.

---

As compared to other ROMs the hotspot is stable and is fast.

Thanks for the continued development! Which version of microG to install for gcam and various mapping apps that require google services?

https://github.com/FriendlyNeighborhoodShane/MinMicroG_releases/releases should do, but you can always manually install microg packages from https://microg.org/download.html

---

Progress update, got Note10+ full ril stack fully working on 8895 devices so no more mix and matched blobs which should generally improve stability and battery life when it comes to ril related stuff

Thanks for the latest update!
I meant which one of those packages, from the several on that page, would be best to install just to get gcam and various gps apps that rely on google services working properly?
