derpfest made me want to daily drive a custom rom
android, personal, devokay so i've been sitting on this take for a bit but i need to get it out. material 3 expressive is genuinely one of the best things that's happened to android's look in years, and the custom rom scene is already running with it in ways stock OEM skins just aren't.
let me back up.
material 3 expressive is what android always should have felt like
google dropped material 3 expressive with android 16 and it's not just a coat of paint. the whole motion system got rebuilt from scratch. they ditched the old duration-based animations (you know, the ones that feel like powerpoint slides) and replaced them with actual spring physics. the kind where when you dismiss a notification, the ones next to it subtly react to your drag. or when you fling down the notification shade it feels like it has real weight. background blur in quick settings and recents now adds actual depth instead of just being a flat overlay on a flat overlay.
the typography got overhauled too, variable fonts, emphasized styles for hierarchy, bold editorial layouts that make important stuff actually pop. there are 35 new shapes in the system with built-in morph animations so buttons and containers can transition fluidly between states instead of just... swapping. it's the kind of attention to detail that apple people usually brag about and android people just sigh about. not this time though.
the 9to5google guys called it "material 3.5" because the first-party google app updates lagged behind the system itself, and honestly that's fair. but the system-level stuff, the launcher, quick settings, recents, all of that? it's an absolute hit.
so i flashed derpfest on my poco x3 pro
the poco x3 pro (vayu) is a 2021 phone with a snapdragon 860. it has no business being this smooth in 2026. but i flashed derpfest on it mostly as a test because i had it lying around and i figured worst case i'd just wipe it.
it wasn't worst case. it was the opposite. the thing runs cleaner than my xiaomi 11t pro on hyperos. like actually noticeably faster, the animations feel snappier, there's no bloat trying to background-update itself every three hours, no ads in the settings app (yes hyperos does that, yes it's embarrassing), no mystery processes eating ram. derpfest ships with dolby atmos baked in, security patches are current, and the team builds their own stuff in-house instead of just frankensteining patches from other roms together. they literally ported the closed-source pixel launcher hotseat search bar and rewrote it openly. they have a live edge-light notification preview where you can tune pulse count and bar width on a device mockup in real time. this is the level of polish we're talking about.
and it's on android 16. on a five year old phone. running better than the software my actual main phone shipped with.
hyperos is just miui with a new name and some blur effects
i know some people will come at me for this but be serious for once. hyperos was supposed to fix miui. instead we got the same telemetry, the same aggressive memory management that kills background apps, the same weekly "bug reports" where they fix three things and break two new ones, and somehow they still haven't sorted out ads in system apps for global users. the animations got prettier but the underlying philosophy of "this is our phone, you just live in it" never changed.
derpfest running circles around it on older hardware really does put things into perspective. when a community rom maintained by a small team on sourceforge makes your flagship feel slow, that's not a derpfest compliment, that's a hyperos problem.
the one actual tradeoff
here's the thing i want to be transparent about because it's real: strong integrity is basically impossible on an unlocked bootloader right now. google has been on a multi-year campaign of progressively patching every workaround the custom rom community comes up with. the play integrity fix project literally got discontinued. you can get basic and device integrity with the right magisk modules, but strong is off the table without a locked bootloader, and most custom roms (including derpfest on xiaomi hardware) can't relock.
what that means practically: google wallet and contactless payments are dead. most banking apps still work fine on basic integrity but google wallet specifically needs strong or it won't let you add cards for tap-to-pay.
i've made peace with this. i use a physical card, it's not the end of the world, and i'm taking the tradeoff of ditching tap-to-pay on my main for an experience that actually respects my phone instead of renting it back to me with ads. when derpfest android 16 stabilizes on the 11t pro (vili) i'm flashing it. the poco was the proof of concept and it passed with flying colors.
the custom rom scene has always been good. but with m3 expressive baked in and teams like derpfest doing real original work instead of just slapping patches on lineage, it's genuinely better than it's been in years. go flash something, your phone deserves better than what it shipped with.
