Samsung Galaxy A07 4G VS Tecno Spark 40

In terms of physical dimensions, the Samsung Galaxy A07 4G and the Tecno Spark 40 are virtually identical. The A07 4G measures 164.4 × 77.4 × 7.6 mm while the Spark 40 comes in at 165.6 × 77 × 7.7 mm — differences so marginal they are imperceptible in daily use. Neither device folds nor claims a rugged build, so both target the same standard-use audience looking for a slim, pocketable candybar form factor.

The one meaningful differentiator in this group is the Ingress Protection rating. The A07 4G carries an IP54 certification, while the Spark 40 steps up to IP64. Both share the same water-resistance level (the ″4″ suffix), meaning neither can handle submersion — only splash and rain protection. However, the first digit tells a different story: ″5″ on the A07 4G means only partial dust resistance, whereas ″6″ on the Spark 40 means complete dust-tightness. In practice, this matters in dusty environments like construction sites, sandy beaches, or arid climates, where fine particles could gradually compromise internal components on the A07 4G but not on the Spark 40.

Overall, the Tecno Spark 40 has a clear edge in this group, strictly due to its superior IP64 dust protection. For users in clean, everyday urban environments the difference is negligible, but for anyone regularly exposed to dust or particulates, the Spark 40′s full dust-tight seal is a tangible real-world advantage.

The display specs for these two devices are remarkably close. Both use an LCD IPS panel, share an identical 720 × 1600 px resolution, and land at nearly the same pixel density — 262 ppi on the Galaxy A07 4G versus 263 ppi on the Spark 40. That one-pixel-per-inch gap is completely invisible to the human eye, and the screen sizes (6.7″ vs 6.67″) are functionally indistinguishable in hand.

What matters more here is what both phones lack rather than where they differ. Neither device offers branded damage-resistant glass, HDR support of any kind, or an Always-On Display. The absence of HDR10 or Dolby Vision means media consumption — streaming video in particular — tops out at standard dynamic range, which limits contrast and color depth compared to even mid-range AMOLED-equipped rivals. The LCD IPS panel type is also worth noting: while it delivers accurate colors and solid viewing angles, it cannot match the deep blacks or power efficiency of OLED technology, especially with dark-themed content.

This group is effectively a tie. The specs are so closely matched that no meaningful real-world difference exists between the two displays. Buyers prioritizing screen quality should note that both phones sit firmly in the budget tier, and the display is the one area where that positioning is most apparent — neither device distinguishes itself from the other here.

Under the hood, the Samsung Galaxy A07 4G holds a substantial advantage. Its Mediatek Helio G99 chip is built on a 6 nm process, compared to the 12 nm node on the Tecno Spark 40′s Helio G81 Ultra. A smaller node means the A07 4G′s chip is more power-efficient and can sustain higher performance levels with less heat — a tangible benefit for extended gaming sessions or heavy multitasking.

The Geekbench 6 scores make the gap concrete: the A07 4G scores 729 single-core and 1979 multi-core, versus just 420 single-core and 1391 multi-core on the Spark 40. Single-core performance is especially relevant for everyday responsiveness — app launches, UI scrolling, and keyboard input — and the A07 4G is roughly 73% faster in that metric. Supporting this, the A07 4G′s RAM runs at 4266 MHz versus the Spark 40′s 1800 MHz, and its memory bandwidth reaches 17.1 GB/s compared to 13.41 GB/s — meaning data moves between the processor and RAM significantly faster, reducing bottlenecks in data-intensive tasks. The GPU turbo clock (2133 MHz vs 950 MHz) further reinforces the A07 4G′s graphical edge for gaming.

The Samsung Galaxy A07 4G wins this group decisively. Despite both phones sharing the same RAM and storage amounts on paper, the A07 4G′s faster chip architecture, superior memory subsystem, and stronger benchmark results translate into a noticeably snappier real-world experience across virtually every use case.

Both phones lead with a 50 MP main sensor and an 8 MP front camera, but the similarities thin out quickly from there. The Samsung Galaxy A07 4G adds a secondary 2 MP lens to its rear system — typically used for depth sensing to enable portrait-mode bokeh effects — while the Tecno Spark 40 relies on a single rear lens. Neither device offers optical image stabilization, so both depend entirely on software for shake correction.

Video recording is where the two phones make notably different trade-offs. The Spark 40 captures footage at up to 1440 × 30 fps, which offers higher pixel resolution than the A07 4G′s 1080p @ 60 fps ceiling — but the A07 4G′s 60 fps cap produces smoother motion, which is more visually impactful for action or fast-moving subjects. Beyond that, the A07 4G also supports slow-motion recording and a built-in HDR mode for photos, plus a timelapse function — none of which are available on the Spark 40. The Spark 40′s only exclusive hardware edge is its dual-LED flash, which can produce slightly more balanced and natural-toned flash illumination than the A07 4G′s single LED.

The Samsung Galaxy A07 4G takes this group. Its broader feature set — slow-motion video, HDR photo mode, timelapse, and a dual-lens rear system — gives it more creative versatility than the Spark 40, which trades those capabilities for a marginally higher video resolution that most users are unlikely to notice in practice.

This is the rare spec group where the comparison ends before it begins. Both the Samsung Galaxy A07 4G and the Tecno Spark 40 run Android 15 and share an identical feature set across every single data point provided — from privacy controls like camera and microphone toggles, to productivity features like split-screen, Picture-in-Picture, and full-page screenshots.

The shared highlights are worth acknowledging for what they mean to users. Both devices offer on-device machine learning, enabling features like Live Text (extracting text from images) without sending data to the cloud — a genuine privacy and usability win. Dynamic theming, customizable notifications, and widget support round out a modern Android experience that neither phone compromises on. Notably, neither device receives direct OS updates from Google, meaning future Android upgrades depend entirely on each manufacturer′s own update cadence.

This group is an absolute tie — not a close call, but a perfect draw. Software feature parity is total, and no advantage can be assigned to either device based solely on the provided data. The choice between these two phones will have to be made elsewhere.

Battery capacity is close but not identical: the Tecno Spark 40 packs a 5200 mAh cell versus the 5000 mAh in the Samsung Galaxy A07 4G. The 200 mAh difference is modest and unlikely to translate into a dramatically longer day, but combined with the Spark 40′s less power-hungry chipset architecture (as seen in the Performance group), it could edge ahead in total endurance for light-to-moderate users.

The more impactful differentiator is charging speed. The Spark 40 supports 45W fast charging, nearly double the A07 4G′s 25W ceiling. In practical terms, this means significantly shorter top-up times — particularly valuable for users who frequently find themselves charging on the go or between tasks. Adding further weight to the Spark 40′s charging advantage, it also comes bundled with a charger in the box, while the A07 4G does not. For budget-segment buyers, the cost of purchasing a compatible fast charger separately is a real consideration.

The Tecno Spark 40 wins this group clearly. Its larger battery, substantially faster charging, and included charger make it the more complete package for battery-conscious users — and the out-of-box readiness of having a 45W charger included is a tangible day-one advantage the A07 4G simply cannot match.

Shared ground is limited here to a single feature: both phones retain the increasingly rare 3.5 mm headphone jack, a welcome inclusion for users who prefer wired audio without adapters. Neither device supports high-resolution Bluetooth codecs like aptX or LDAC, so wireless audio quality is capped at standard levels on both.

The two meaningful differentiators pull in opposite directions. The Tecno Spark 40 features stereo speakers, while the Samsung Galaxy A07 4G does not. For media consumption — watching videos, gaming, or listening to music without headphones — stereo output creates a noticeably wider and more immersive soundstage compared to a single mono speaker. This is one of the more impactful day-to-day audio differences a phone can have. The A07 4G counters with a built-in FM radio, which the Spark 40 lacks — useful for users in regions with strong terrestrial radio coverage, or anyone who prefers radio as a low-data audio source.

On balance, the Tecno Spark 40 has the edge for most users. Stereo speakers deliver a broader, more consistent benefit across everyday use cases, whereas FM radio appeals to a narrower audience. Unless radio access is a specific priority, the Spark 40′s speaker setup is the more impactful audio advantage.

The connectivity profile of these two phones is largely identical — dual SIM, USB Type-C, expandable storage, GPS with Galileo support, Wi-Fi, and a fingerprint scanner are all shared. Notably, neither device offers NFC or 5G, which places both firmly in the budget 4G tier and rules out contactless payments via NFC-based systems for users who rely on that feature.

The one area where the specs diverge is cellular data throughput. The Samsung Galaxy A07 4G supports download speeds of up to 650 Mbit/s and upload speeds of 150 Mbit/s, compared to 300 Mbit/s down and 100 Mbit/s up on the Tecno Spark 40. In practice, real-world mobile speeds rarely saturate either ceiling — network infrastructure and signal quality are the dominant bottlenecks. However, the A07 4G′s higher theoretical ceiling can offer a modest advantage in congested networks or when transferring large files over mobile data.

The Samsung Galaxy A07 4G takes a narrow edge here on the strength of its superior cellular speeds, though this advantage will be imperceptible to the average user in typical conditions. For everything else in this group, the two phones are evenly matched — and the shared absence of NFC is the more consequential shared limitation for buyers who had hoped to use contactless payment features.

The Miscellaneous group offers nothing to separate these two devices. Every data point — the presence of a video light, and the absence of sapphire glass, a curved display, and an e-paper display — is identical across the Samsung Galaxy A07 4G and the Tecno Spark 40. This is a complete tie by every available measure in this category.

The shared video light (the rear flash doubling as a torch during video recording) is a standard budget-tier inclusion and carries no differentiating weight here. The absence of premium features like sapphire glass or a curved display is equally expected at this price point and affects neither phone more than the other.

There is no winner to declare. Based strictly on the provided data, this group contributes nothing to distinguish one phone from the other, and buyers should weigh the more substantive differences found in other spec categories when making their decision.
