The Asus ROG Phone 3 is supposed to be a handheld GPU with a SIM card attached, not a camera flagship. Yet Asus quietly turned its so‑called side quest into one of the more competent gaming‑phone camera setups around.
If you’re expecting Pixel‑level computational magic, walk away. If you just need your gaming slab to not embarrass itself on Instagram, things get interesting.
Hardware: IMX686 Does the Heavy Lifting
Asus didn’t reinvent anything in hardware, but they did pick the right pieces.
The main camera is a 64MP Sony IMX686 (1/1.7″, 0.8µm pixels) behind an f/1.8 lens with 2×1 OCL PDAF. No OIS, no laser AF, and just a single LED flash. On paper, that’s mid‑2020 flagship‑lite, not top‑tier.
Next to it you get a 13MP ultrawide using OmniVision’s OV13855 with a 125° field of view and a dim f/2.4 lens. It’s fixed‑focus and leans more toward “gets the shot” than “wallpaper material.”
The third rear camera is a 5MP f/2.0 macro module based on an OV8856 sensor downscaled from its native 8MP. It’s still fixed‑focus, but it’s actually a functional macro rather than a useless 2MP sticker.
On the front, Asus drops in a 24MP Quad‑Bayer OmniVision OV24B1Q (0.9µm, f/2.0). Again, no autofocus, but tuned for arm’s‑length selfies and—more importantly for this crowd—streaming.
None of this is halo‑phone stuff, but for a device that spends most of its life at 144Hz in landscape mode, it’s more than a token effort.
Camera App: Gamer UI, Serious Controls
The ROG Camera app looks as loud as the phone, but underneath the RGB‑adjacent styling it’s surprisingly logical.
The basics are obvious: photo, video, portrait, and a macro toggle that the app actually suggests when you move too close to a subject. Scene detection runs in the background and triggers HDR and Night mode prompts when needed.
Portrait mode is where Asus hides the full beauty arsenal: cheek thinning, eye enlargement, skin brightening, smoothing, tone shifts. Push the sliders and you’ll get “MMO avatar” levels of plastic; keep it restrained and the results are usable.
Night mode has a custom exposure picker with two dynamic options—short and long—whose actual second counts depend on ambient light. In really dark scenes this can go all the way out to 25 seconds when the phone thinks it’s on a tripod, and it’ll do that even from the default Photo mode.
The serious stuff lives in Pro and Pro Video:
- Manual WB from 4500K to 7500K
- Exposure compensation from −2 to +2
- ISO 25–3200
- Shutter speeds from 1/60s to 32s
- Manual focus slider plus level meter and histogram
For a ‘non‑camera’ phone, that’s closer to what I expect from an enthusiast slab than a gaming toy.
Still Image Quality: Good Light, Good Results
The IMX686 is doing what it always does: 64MP in, ~16MP out thanks to Quad‑Bayer binning.
In daylight, detail is strong and colors lean natural rather than social‑media neon. HDR auto kicks in reliably when needed. There’s more noise and narrower dynamic range than the best 2020 camera flagships, but for a gaming phone it clears the bar easily.
You can force full 64MP, but—as usual with Quad‑Bayer—there’s barely any real detail gain and you get more noise, chromatic aberrations, and “invented” lines in fine textures. Use it if you must crop aggressively, otherwise stay in binned mode.
Portraits are a pleasant surprise. Edge detection is solid, background blur looks natural, and the algorithm even does a decent job with non‑human subjects. Just don’t crank the beauty sliders unless you enjoy uncanny valley selfies.
Zoom is pure sensor crop from the main cam, with Asus marketing “lossless” 2x off the 64MP data. Practically, 2x looks usable but not truly lossless, and 8x is heavily processed but still surprisingly readable—for a phone with no telephoto.
The 13MP ultrawide is exactly what the spec screams: serviceable and soft. HDR helps a bit with shadow detail, but between the dim f/2.4 aperture and the average sensor, this is a contextual lens, not your main shooter.
The 5MP macro takes effort. Distance is picky and detail isn’t amazing, but with patience you can get legitimately nice close‑ups. At least the app doesn’t make you dig for it and nudges you to switch when you’re too close on the main lens.
Selfies out of the 24MP Quad‑Bayer front cam are better than they have any right to be on a gaming device: 6MP binned files, good detail, balanced colors, and decent dynamic range in mixed light. Portrait mode sometimes loses tiny hairs or glasses edges, but the blur looks convincing overall.
Low Light & Night Mode: Algorithm to the Rescue
Low‑light performance on the main cam is a mix of “better than expected” and “you can see where they cut costs.”
The good: noise is surprisingly controlled for a no‑OIS setup, detail is adequate for social use, and the camera rarely freaks out with weird light sources. Auto Night mode does a smart job of deciding when to stretch exposure and by how much, without forcing you into a separate mode.
The caveats: dynamic range is still a weak point. Night mode can pull a lot of detail back out of dark areas, but it doesn’t do much for clipped highlights around bright lamps or signage. Dedicated Night mode tends to push exposure a bit more than auto, which helps in very dark scenes but doesn’t magically fix blown highlights.
The ultrawide is where things fall apart. f/2.4 plus a smaller sensor means mushy, noisy frames in low light. Night mode can drag it from “trash” to “just about usable,” but if light’s bad, stick to the main cam.
The selfie camera holds up well until it gets properly dark. Indoors with mediocre lighting, it still delivers clean shots; once you add tricky point light sources, noise and limited dynamic range catch up. There’s no Night mode for selfies, which is a miss.
Video: 8K Specs, 4K Reality
Asus clearly spent time on video. The ROG Phone 3 shoots:
- Up to 8K30 on the main camera
- 4K at 30/60/120fps
- 1080p at up to 240fps, 720p at 480fps
- 4K30 on the ultrawide
- 1080p30 on the selfie cam
The headline is 8K with EIS and advanced audio. Bitrate hovers around 104 Mbps, detail is excellent, and colors stay in that “not oversaturated, not dull” middle ground. Frame rate isn’t perfectly flat, but stutters are infrequent.
Dynamic range is again behind the best 2020 flagships across all resolutions; expect clipped highlights and crushed shadows in tough scenes. Drop to 4K60 and you get basically the same processing and strong detail with more practical file sizes.
The ultrawide’s 4K30 is notably weaker: narrower dynamic range, softer detail, and darker output, but color matching to the main cam is decent.
Stabilization is where Asus flexes. There’s no OIS anywhere, but the 3‑axis EIS is aggressive—in a good way—and works up to 8K on the main camera and 4K on the ultrawide. The trade‑off is obvious crop, yet the results are very watchable, even while walking.
HyperSteady goes harder: it crops heavily into the ultrawide, locks you to 1080p, and produces “action cam”‑style floaty footage that stays stable even when you start sprinting. You lose resolution and can’t use it with smooth zoom, but for chaotic handheld clips it’s genuinely useful.
Audio is another quiet win. A quad‑mic array feeds features like mic zoom and wind suppression, both toggleable in the video UI. In practice they behave as promised, and the phone keeps those audio tricks active even at 8K—something a lot of OEMs skip.
HDR video is the one experimental area. You have to basically unlock it via an in‑app suggestion after shooting 8K in bright sun, it’s capped at 4K, and the quality is inconsistent. When it hits, highlight and shadow detail jump noticeably. When it misses, you get exposure flicker and weird shifts across the frame. Asus was still on beta firmware in the unit tested, so this feels like a feature in progress, not a reason to buy.
Autofocus occasionally hesitates in video, leading to brief blurry patches before it locks. Once it finds focus, it generally holds it, but this is another area where firmware needs tightening.
Low‑light video from the main cam is usable if you keep expectations in check. EIS still works well, noise reduction is clearly working overtime, and dynamic range issues get louder. On the ultrawide, low‑light clips are borderline unusable—too dark and muddy to recommend.
Selfie video, by contrast, is strong for this class: 1080p30 with EIS, generous depth of field from the fixed‑focus module, and quality that’s entirely acceptable for streaming—if you can deal with holding a 240g phone at arm’s length or mount it on something.
Verdict: Not a Camera Phone, But Absolutely Camera‑Capable
If you judge the ROG Phone 3 as a 2020 camera flagship, it falls short: no telephoto, no OIS, middling ultrawide, and dynamic range that can’t hang with the best.
If you judge it as what it actually is—a gaming supercar with a camera strapped on—the story flips. Asus didn’t just tick a spec box. They shipped:
- A proven 64MP IMX686 main sensor with competent tuning
- Genuinely usable Night mode that auto‑triggers
- Extensive Pro and Pro Video controls down to 32s shutter
- 8K30 with EIS and advanced audio options
- A solid selfie system clearly tuned with streamers in mind
The weak links are obvious: ultrawide, low‑light video on anything but the main camera, HDR video inconsistency, and occasional AF hunting. None of that is surprising at this price/priority mix, and most of it is fixable—or at least improvable—via firmware.
So no, the ROG Phone 3 is not the phone mobile photographers should buy. But if you’re here for 144Hz gaming and Snapdragon 865+ performance, its camera system is far from an afterthought. It’s competent, flexible, and sometimes genuinely impressive, especially in video and manual control.
For a gaming phone, that’s a win.
