I’m using LineageOS since several weeks now and I can say it works pretty well, not better than FPOpen OS, thought. I would say that power consumption is similar.
I badly miss GravityBox, there are so many tweaks! The only advantage I see with LineageOS is that I can hide root when using my bank app (BCGE - CrontoSign) with iSU. I was not able to use this app under FPOpen OS with RootCloak. This is the only thing which refrain me from returning to FPOpen OS.
@AnotherElk: Mainly tweaks related to the Status bar like Battery indicator which fits my aging eyes, Data traffic indicator.
And also more volume steps in music.
@5t0rmr1d3r: Really! Will try this, thanks for the info!
