Quick moments often pass in a flash: a child jumping, a cat chasing a toy, or a single clap on stage. On the Camon 40, there’s Flash Snap that can shoot up to 20 photos in an instant, plus an Action Button you can set so the camera is always ready. The challenge: when is this feature effective, and how do you set up the button so you don’t panic at the crucial second?

Quick Reference Table

Context: what Flash Snap aims to achieve

In the ~IDR 2-million class, the Camon 40 clearly positions the camera as a selling point: a 50MP OIS main camera, 8MP ultrawide, and a Flash Snap feature that captures many frames within 1–2 seconds. The practical goal is simple: increase the chance of getting one sharp photo amid fast motion without having to tap repeatedly.

How to set the Action Button so it’s always ready

• Open the Action Button settings (the dedicated button on the left side).
• Set the double-press function to Flash Snap (or directly to the Camera app if you want auto mode).
• Alternative: the double-press can be routed to a favorite app (e.g., TikTok/AnTuTu), but for quick-moment photography, prioritize Flash Snap.
• The left button’s long-press is locked to Ella (Tecno’s assistant) and cannot be customized.
• The power button’s long-press (right) can be set to Google Assistant if you need an alternative voice assistant.

Practical tips:

• Avoid assigning confusing dual functions in critical moments. One button = one habit.
• Test your grip flow: which finger reaches the left button fastest for a double-press.

Field-use checklist — Maximize Camon 40 Flash Snap: 20 Photos in an Instant + Set the Action Button So You Don’t Miss Moments

• Ensure sufficient light (outdoors cloudy/sunny, indoors near a window/light).
• Set the Action Button (double-press) to Flash Snap before the event starts.
• Open Flash Snap, aim at the subject, then slide the shutter button to the left to choose the number of frames (1–20).
• For brief actions (a clap, a short jump), choose 10–20 frames to increase your odds.
• Keep the phone steady; OIS helps, but major shake can still blur.
• After the burst, pick the best frame; delete the rest to save space.

When is Flash Snap most effective?

• Fast but not extreme motion: a child running lightly, a pet jumping, a futsal goal celebration.
• Bright scenes: daytime or well-lit rooms.
• Moments that often “blink past”: blowing candles, tossing a graduation cap, confetti.

Based on reviewers’ explanations, Flash Snap is less optimal for:

• Very fast actions such as ultra-brief eye blinks.
• Dark/low-light conditions, because blur and noise risks increase.

Master the frame count: what is 1–20 for?

• 1–5 frames: light movement, long pauses between actions.
• 6–10 frames: mid-level moments (bright indoor events, quick hand movements).
• 11–20 frames: short peak actions (jumps, claps, confetti) in adequate light.

The more frames, the higher the chance of a “peak photo”—but selection and storage burden also increase.

Storage management after a burst

• A single Flash Snap session can add dozens of photos at once. After selecting, promptly delete unused frames.
• The 256GB variant gives more breathing room than 128GB; still make a habit of curation so the gallery doesn’t pile up.

Limitations and trade-offs to keep in mind

• Screen visibility: under harsh midday sun, brightness can struggle; compose quickly before it gets blazing.
• Button customization: the left button’s long-press is locked to Ella, so you can’t assign flashlight/quick record there.
• Moving video: for recording, the stabilizer drops resolution to 1080p 30 fps and there is still micro-jitter—prioritize photos if the goal is to freeze action.

GizmoKita Insight

• Suitable for: users who prioritize “peak capture” chances in daily activities and need instant camera access via a physical button.
• Not suitable for: hunters of ultra-fast action in low light, or those who want full long-press customization on the left button.
• Trade-off: the more frames, the greater the curation and storage load; the best quick access is via the Action Button double-press, but the left long-press isn’t flexible.

Quick Summary (TL;DR)

• Set the Action Button (double-press) to Flash Snap.
• Use in sufficient light; pick 10–20 frames for brief action.
• Keep the phone steady; leverage built-in OIS.
• Immediately select and delete the rest to save space.
• Avoid high expectations for ultra-fast action or low light.

GizmoKita Verdict: Worth Buying or Not?

If your priority is capturing quick moments with a high chance of getting one sharp frame, the Flash Snap feature on the Camon 40—backed by OIS, an ultrawide, and instant access via the Action Button—delivers real value in its price class; just consider the low-light and left long-press customization limits.

FAQ

How do I activate Flash Snap?

Open the camera, select Flash Snap mode, then slide the shutter to the left to choose 1–20 photos.

Is Flash Snap effective in dark conditions?

It’s most effective when lighting is sufficient; in low light the risk of blur/noise increases.

Do I need to hold the shutter button for a burst?

No. Slide the shutter to the left to set the number of frames; simply holding it won’t shoot.

Can the Action Button long-press be customized?

The left button’s long-press is locked to Ella; what you can set to Google is the power button’s (right) long-press.

How many frames are ideal?

For short peak moments, start with 10–20 frames; adjust to the action’s duration and the time you have for culling afterward.

Brief Closing

Set up the Action Button, use Flash Snap in adequate light, and choose the frame count according to the action’s duration. With this flow, your chances of getting a peak photo from a fleeting moment will be much higher.
