GCam Infinix Smart 20: Does a Port Work? Best Camera App (2026)

The Infinix Smart 20's camera struggles with bright skies and dim rooms, and the hardware explains why. It has a single 8MP main camera (f/2.0, autofocus) on a small 1/4-inch sensor with 1.12µm pixels, driven by a MediaTek Helio G81 Ultimate. A sensor that small collects very little light. The stock camera captures one frame and then sharpens and denoises it, with no strong multi-frame HDR pipeline behind it. Daylight shots look fine on the phone's 720p screen. Bright skies clip to white, though, shadows go muddy and indoor photos come out grainy. No app changes the sensor. What an app can change is how many frames get captured and how each one is exposed.

SensePose is an AI camera app for Android built for phones like this one. Its real-time AI Pro Mode reads each scene and sets ISO, EV and shutter live, the way a photographer would. It then merges a RAW HDR+ multi-frame burst on-device, which is the same multi-frame method Google Pixel and iPhone cameras use, for accurate, true-to-scene color where GCam ports often wash out. It is free on Google Play, needs Android 10+ and is about 28 MB.

Below: whether a GCam port works on the Smart 20, the stock settings worth changing, and what to do in low light.

Infinix Smart 20 camera specs at a glance

Two things in that table matter for photos. First, the sensor is tiny even by budget standards, so in dim light the phone has to raise ISO a long way, and noise follows. Second, the screen is 720p. A photo can look sharp on the phone and soft once you zoom in or send it to a bigger screen. Judge your shots at 100% zoom, not at the full-screen preview.

GCam for Infinix Smart 20: quick FAQ

Plenty of Smart 20 owners search for a GCam port. The short version, before you sideload anything:

Is there an official GCam for the Infinix Smart 20?

No. Google Camera is only officially available on Pixel phones. Anything you find for the Smart 20 is a community port: a modified APK built for other hardware, usually tuned for Qualcomm Snapdragon phones. The Smart 20 runs a MediaTek chip, and MediaTek has historically been harder for porters to support.

Will a GCam port work on the Smart 20?

Maybe, partly. On MediaTek budget phones the usual pattern is that some ports open and take photos while others crash on launch, freeze in HDR+ or night mode, or save black or green frames. Even when a port runs, its processing was tuned for a different sensor, so color can come out washed out or tinted and white balance can drift. Try ports from a known porter, test one at a time, and expect to try several before one is stable.

How do I check whether my phone supports third-party camera apps?

Install a free Camera2 API checker from Google Play and look at the hardware level for the rear camera. "FULL" or "LEVEL_3" means apps get full manual control. "LIMITED" means some features work. "LEGACY" means advanced apps, GCam ports included, will struggle. Budget MediaTek phones often report LIMITED, so check before you spend an evening with APKs.

Do I need to root the phone?

No. GCam ports and SensePose are normal app installs. You don't need root, an unlocked bootloader or any system changes. Only install APKs from sources you trust, and only GCam ports should need sideloading at all.

Why does GCam look worse on my Smart 20 than on a Pixel?

A port's color and HDR tuning comes from the phone it was built for. On a different sensor, the same tuning often makes color look flat, pale or tinted. GCam also gives you very little manual control: it is mostly locked to auto. If the auto result is off, there's little you can do about it. That's the gap SensePose aims at. It keeps the multi-frame merge, and the AI sets exposure for each scene on your phone's own sensor.

Best camera apps for the Infinix Smart 20, ranked

1. SensePose: real-time AI Pro Mode sets ISO, EV and shutter per scene, then merges a RAW HDR+ burst on-device and applies cinematic tone grading. AI background removal and AI edit are built in, and there's an optional, experimental framing-advice feature. The whole camera is free. Free exports carry a small watermark, and free users get 30 framing-advice requests a month. Pro removes the watermark.
2. GCam port: worth trying if you find a stable build. It's free and does multi-frame HDR+. On MediaTek it's hit and miss, it's locked to auto, and color often washes out.
3. Stock XOS camera: the most reliable, fastest to open, and the one guaranteed to support every camera mode and the phone's video options. It captures single frames, so dynamic range and low light are its weak spots.

A sensible setup is to keep the stock camera for video and quick snaps and use a multi-frame app for photos you care about.

Infinix Smart 20 camera settings that actually help

Whichever app you use, these settings make the biggest difference on a small sensor:

• Shoot at full 8MP, 4:3. 4:3 matches the sensor's native shape. 16:9 and full-screen modes crop the frame, so you throw away pixels you can't spare on an 8MP camera.
• Turn off beauty and "AI" filters for normal photos. On the stock camera, beauty modes smooth skin by blurring detail, and on a 1/4" sensor there isn't much detail to lose. Use them only for selfies if you like the look.
• Turn on HDR in daylight with a bright sky. Stock HDR helps a little with clipped skies. Hold still while it processes.
• Tap to focus and expose on your subject. Then drag the exposure slider down slightly (around −0.3 to −0.7) when the sky or a lamp is in frame. Keeping highlights from clipping matters more than lifting shadows, which bring noise with them.
• Avoid digital zoom. The Smart 20 has no telephoto lens. Zooming just crops and upscales an 8MP image. Walk closer, or shoot wide and crop later.
• Wipe the lens. It sounds trivial, but a fingerprint on a budget lens causes more haze and flare than any setting can fix.
• Video: 1080p at 30fps for most clips. The phone can record 2K, but 1080p files are smaller and easier to share, and the gain from 2K on this sensor is modest. Hold the phone with both hands, because there's no optical stabilization.
• Use Pro mode carefully. If you set ISO by hand in the stock app, keep it as low as the light allows and brace the phone, because shutter speeds get slow. Or let SensePose's AI Pro Mode make that call for each scene.
• Check storage. On the 64GB model, a nearly full phone can slow the camera app and delay saving. Keep a few GB free.

Low light on the Infinix Smart 20

An entry phone struggles most in low light. Software also makes its biggest visible difference here.

What the stock camera does after dark

With a single frame, the camera has two bad options. It can raise ISO, which fills the image with grainy color noise. Or it can slow the shutter, which blurs anything that moves, including your hands. Most stock cameras do some of both and then apply heavy noise reduction. That cleans up the grain but smears fine detail into a watercolor look, so faces look waxy and text gets fuzzy. Stock night mode, where it exists, helps a little but can't change how much light one frame collects.

Why a multi-frame merge helps

Taking several short frames and merging them averages out random noise while keeping each frame short enough to stay sharp. That's the basic idea behind HDR+ on Pixel phones and similar pipelines on iPhone. Working on RAW sensor data, before the phone's own JPEG processing, keeps more of the shadow and highlight information to merge. Our explainer on RAW HDR+ goes through how it works in more detail.

On a 1/4" sensor, a merge won't make a dark room look like daylight. What it typically gives you is less grain, cleaner shadows and color closer to what you saw, instead of a muddy orange cast. SensePose's AI Pro Mode also picks ISO and shutter per scene, so the frames going into the merge are exposed for the light you actually have.

Practical low-light tips

• Brace the phone. Lean it on a table, wall or railing. Every multi-frame method works better when the phone moves less between frames.
• Find the light. Turn your subject toward a lamp or window. A little more light does more than any setting.
• Skip the flash for most scenes. The LED flash flattens faces and blows out nearby objects. Use it only when there's no other light at all.
• Keep subjects still for a second. Ask people to hold still until capture finishes.
• Don't push exposure up in editing. Brightening a dark shot afterwards mostly brightens the noise.

More options are in our guide to the best low-light camera apps for Android.

What SensePose won't do

• It doesn't change the hardware. The Smart 20 still has an 8MP, 1/4" sensor and no telephoto or ultrawide lens.
• It doesn't upscale images, and it has no night vision or motion/live photo mode.
• Fast-moving subjects in very dim light are still hard for a multi-frame merge, because the subject moves between frames.
• It's meant for budget and mid-range phones. On flagships that already have a strong multi-frame pipeline, you won't see a meaningful difference.

FAQ

What is the best camera app for the Infinix Smart 20?

For photos, a multi-frame app helps this phone most, because its stock camera captures single frames on a small 1/4" sensor. SensePose sets ISO, EV and shutter live per scene with its AI Pro Mode and merges a RAW HDR+ burst on-device. It's free on Google Play. Keep the stock camera for video.

Does GCam work on the Infinix Smart 20?

There is no official Google Camera for it, only community ports. Because the Smart 20 uses a MediaTek Helio G81 Ultimate, ports are hit and miss: some run, others crash or produce tinted, washed-out color. Check the Camera2 API level first and test ports one at a time.

How many megapixels is the Infinix Smart 20 camera?

The rear camera is a single 8MP unit with an f/2.0 lens, a 1/4-inch sensor, 1.12µm pixels and autofocus. The front camera is also 8MP. It records video up to 2K (1440p) at 30fps.

What are the best Infinix Smart 20 camera settings?

Shoot at full 8MP in 4:3, turn off beauty filters, tap to focus on your subject and lower exposure slightly when the sky is in frame. Avoid digital zoom, wipe the lens, and record video at 1080p 30fps. In low light, brace the phone and avoid the flash where you can.

Why are my Infinix Smart 20 photos grainy at night?

The small sensor collects little light, so the camera raises ISO, which adds noise, and then applies heavy noise reduction, which smears detail. Merging several frames reduces that noise. Bracing the phone and finding more light both help too.

Is SensePose free on the Infinix Smart 20?

Yes. The whole camera is free, including AI Pro Mode and the RAW HDR+ merge. Free exports carry a small watermark, and the free tier includes 30 framing-advice requests a month. Pro removes the watermark. It needs Android 10 or newer.
