Introduction

Here's my list of best custom ROMs for those who still needs to use Android. Keep in mind that this is my own opinion, and this page ignores any issues with hardware and/or firmware as they cannot be modified / audited to become trustworthy.

For those who has no use for Android devices, there's only one recommendation : Discard them... ok that's 2, considering DigDeeper's link (which I hypocritically & ironically agree with despite my site's Android contents).

Best for security buffs

If you take security too seriously & would like to keep using Android in any form, stop reading any further, get the latest "affordable" Pixel (regardless of my disdain for them nowadays), and flash GrapheneOS (despite my obvious issues with it).

If you're asking for alternatives for GrapheneOS, don't bother. Here's the alleged "alternatives" (most supports verified boot except for /e/) & reasons why I don't recommend them (as far as I experienced) :

If you also care about privacy (in addition to security), here's a few tips I would offer up for those GrapheneOS users :

Least worst for now

For A11, my least worst option would be ArrowOS, if it's available. Here's why I'd rather use it over crDroid (yes, this is a more personal rehash of ArrowOS' advantages):

And with these tradeoffs:

For A11, here are some of my alleged alternatives & why it doesn't pass as my "best A11 ROM", let alone "truly best ROM of all time".

For A12(L), the least terrible ROM is crDroid. Here's a short-ish list (actually a rehash of its advantages, but a bit more personal) of why I believe it's the least terrible :

However, there are a few issues that keeps me from fully shilling for crDroid (if at all) :

If I were to have any other alternatives worth mentioning, I would have already made sure to list them above. Here are those that could have been my choice, yet couldn't :

DivestOS

And, moving to the 2nd fiddle for both security buffs & me, DivestOS. Previously, I dismissed it due to uneven device support. However, I forgot to look at it from a more positive stance, so here it is.

First off, let's start with its benefits :

And, here are its issues :

Can we make an even better one?

Since every ROMs suck to a degree (though not as bad as phones are), let's throw some insight on the truly perfect custom ROM. Or, in other words, how we can do better.

To start, we'll use LineageOS, as it's easier to fix than crDroid (despite being the least worst). I could've used ArrowOS, but I've already went with LineageOS so...

Mandatory additions

Starting with the custom ROM :

Optional additions

Here's the optional addition - the niggles that I'm cool not having, but very welcome if it's there.

Starting with the custom ROM :

Then, for the website; which is not that important in itself (hence being made optional) but may also keep our red flags off :

Forbidden additions

Additions I don't want to see at all in the "perfect" ROM.

Starting with the custom ROM itself (most of which are already present at my custom ROM rules (major & minor), so this is mostly a recap) :
