I have heard of using bromite via the same installer used to install the OS. I have also heard of some sort of Fennec alternative that oF2pks mentions.
Bromite is a Chromium fork with ad blocking and privacy enhancements
There are the normal browser and webview.
The installation of bromite webview depends on your ROM and can be a tricky thing.
I guess you can do it with ADB as root.
It is a delicate and probably unnecessary process.
A LineageOS update can override it.
Do you really use webview?
amh, it’s package id says org.lineageos.jelly version 1.0. i am sure that version thing is not significant here and prolly is just an oversight/ignorance. but yeah, it says jelly there…
Back to the original topic, if your ROM is rooted with Magisk one can use a module to install the Bromite webview.
If the ROM isn’t rooted but the device is (TWRP installed for instance) then one can flash the NanoDroid Bromite webview installer. After that, add the Bromite repo to F-Droid to keep it updated.
