To the tech experts, is it possible to uninstall the google version on our android phones and install it with the LineageOS as mentioned in the article?
Yes. You will find instructions for how to do so on their respective websites:
https://wiki.lineageos.org/devices/ and
https://grapheneos.org/install.
Be aware that doing so is not without risk. It is possible to brick your phone if you make mistakes while installing a custom OS.
Unfortunately my new phone is not supported (a30) in this list.
Maybe I will install in my old one just for testing purposes.
But let me ask. You said there was a risk and it may brick the phone. But can't you just factory reset the phone to fix it?
