I am trying to work out whether it would be possible to use a custom rom such as LineageOS without flashing Gapps rather than using the LineageOS+MicroG as an option. The basic requirement is to be able move away from the Big Brother.
I have read that LineageOS+MicroG option is a good one but it creates security risks because of the need to do signature spoofing.
I am just a newbie here and wondering whether it would be possible to install a downloaded apk directly on LineageOS? If yes, would like to find more details on this process. If no, are there any solutions to this problem or we just have to put up with the Big Brother until Linux phones make inroads into this space?
EDIT: Thanks for all those who provided valuable comments/suggestions. I decided to try out LineageOS for MicroG and found it quite a painless process. The phone works great without the Big Brother tracking me. I also run DNS66 (from F-Droid Store) which stops ads on some apps. Overall, pretty much impressed with the outcome.
com.google.android.gmsclaiming to be Play Services (Google Mobile Suite) is not developed by Google, so needs to spoof its signatures. // All of this has nothing to do with app installation, which always works. But apps dependent on Google APIs may not work without GMS/GSF etc. Or may work with limited functionality.
