In terms of physical footprint, these two phones are remarkably close. Both share nearly identical widths (77.2 mm vs 77.6 mm) and similar heights, making them essentially the same size in hand. The S25 Ultra is slightly slimmer at 8.2 mm thick compared to the Lava Shark 4G's 8.5 mm, and its marginally smaller volume reflects a more compact internal packaging — though none of these differences are meaningful in daily use.

Where the two phones diverge significantly is weight and water resistance. The Lava Shark 4G is noticeably lighter at 200 g versus 218 g for the S25 Ultra — an 18-gram gap that, while it sounds minor, is actually perceptible during extended one-handed use or long calls. On durability, the gap is even more consequential: the S25 Ultra carries an IP68 rating, meaning it can survive full submersion in water up to 1.5 meters for 30 minutes, whereas the Lava Shark 4G's IP54 rating only guarantees protection against splashes and dust — not submersion.

Neither phone offers a rugged build or foldable form factor. Overall, the Samsung Galaxy S25 Ultra holds a clear edge in real-world durability thanks to its superior IP68 water resistance, which matters greatly for users who are near pools, rain, or any risk of drops in water. The Lava Shark 4G counters with a lighter body, but that advantage is secondary when the protection gap is this wide.

Display:
Display type LCD, IPS OLED/AMOLED
screen size 6.67" 6.9"

has branded damage-resistant glass
supports HDR10
supports HDR10+
Always-On Display

Has a secondary screen
has a touch screen

The display gap between these two phones is substantial. The S25 Ultra uses an OLED/AMOLED panel while the Lava Shark 4G relies on an LCD IPS screen — a fundamental difference in technology. OLED produces true blacks and superior contrast by lighting pixels individually, while LCD backlighting results in less vibrant colors and weaker outdoor visibility. Combined with a pixel density of 498 ppi versus just 269 ppi on the Lava Shark 4G, the S25 Ultra renders text and images with a level of sharpness that is clearly perceptible to the naked eye, especially at close viewing distances.

The S25 Ultra also supports HDR10 and HDR10+, which means compatible streaming content — Netflix, YouTube, and similar platforms — will display with a wider dynamic range, richer highlights, and deeper shadows. The Lava Shark 4G supports neither. Add to that the S25 Ultra's Always-On Display and branded damage-resistant glass, and the practical advantages extend beyond just image quality into daily usability and durability. Both phones share a 120Hz refresh rate, so scrolling and animations feel equally fluid on either device.

The Samsung Galaxy S25 Ultra holds an overwhelming advantage in this category. The combination of OLED technology, near-500 ppi sharpness, HDR support, and screen protection places it in a different league — the Lava Shark 4G's display is functional, but it cannot compete on any of the key quality metrics.

The raw performance difference here is not a gap — it is a chasm. The S25 Ultra runs on the Qualcomm Snapdragon 8 Elite, built on a cutting-edge 3 nm process, while the Lava Shark 4G uses the Unisoc T606 on a 12 nm node. Smaller semiconductor size directly translates to greater power efficiency and higher transistor density, enabling far more compute per watt. The Geekbench 6 results make this concrete: the S25 Ultra scores 3057 single-core and 9846 multi-core, versus 371 and 1391 on the Lava Shark 4G. That is roughly an 8x lead in multi-threaded workloads — meaning app launches, multitasking, and any CPU-intensive task will feel dramatically snappier on the S25 Ultra.

GPU performance tells the same story. The S25 Ultra's Adreno 830 runs at up to 1200 MHz with 1536 shading units, compared to the Mali G57 MP1's 650 MHz and a mere 64 shading units. In practical terms, this means the S25 Ultra can handle demanding 3D games, video editing, and AI-accelerated tasks with ease, while the Lava Shark 4G is suited only for light gaming and basic media. Memory bandwidth reinforces this: 85.1 GB/s on the S25 Ultra versus 12.8 GB/s on the Lava Shark 4G, supported by faster DDR5 RAM at 5300 MHz versus DDR4 at 1600 MHz. The S25 Ultra also ships with 1TB storage and 12 GB RAM, dwarfing the Lava Shark 4G's 64 GB and 4 GB configuration.

Notably, despite its far greater power, the S25 Ultra operates at a lower TDP of 8.2W versus 10W for the Lava Shark 4G — a testament to the efficiency gains of the 3 nm architecture. The Samsung Galaxy S25 Ultra wins this category without contest, outperforming the Lava Shark 4G across every meaningful performance metric.

Camera hardware is another area where the two phones occupy entirely different tiers. The Lava Shark 4G offers a single 50 MP rear sensor with no optical image stabilization and no optical zoom, capping video at 1080p 30fps. The S25 Ultra fields a quad-camera array with a 200 MP primary sensor, two additional 50 MP lenses, a 10 MP shooter, OIS, 5x optical zoom, and video recording up to 8K (4320p) at 30fps. The practical implications are significant: OIS reduces motion blur in handheld shots and low-light video, optical zoom preserves image quality at a distance where the Lava Shark 4G would only offer digital cropping, and 8K recording future-proofs footage for high-resolution editing.

Beyond resolution and zoom, the S25 Ultra brings several meaningful capability advantages. It supports RAW shooting, which gives photographers access to unprocessed sensor data for professional post-processing — the Lava Shark 4G does not. It also includes laser autofocus, a BSI sensor for improved low-light performance, manual shutter speed control, and HDR10 video recording. Both phones share a solid baseline of features — phase-detection autofocus, continuous autofocus in video, HDR photo mode, timelapse, slow-motion, and manual controls for ISO, white balance, focus, and exposure — so the Lava Shark 4G is not without capability for everyday shooting.

That shared baseline, however, only highlights how wide the gap is at the top end. The Samsung Galaxy S25 Ultra wins this category decisively, offering a multi-lens versatile system with professional-grade controls, far superior video resolution, and hardware features the Lava Shark 4G simply does not have.

Both phones run Android and share an impressively broad set of software features — dark mode, dynamic theming, split-screen multitasking, picture-in-picture, widgets, offline voice recognition, on-device machine learning, and a full suite of privacy controls are present on both. For the vast majority of everyday software interactions, users of either device will find a familiar and capable Android experience. The Lava Shark 4G runs Android 14 while the S25 Ultra ships with Android 15, a difference that is incremental in day-to-day use but means the S25 Ultra starts with access to the latest platform security patches and behavioral improvements.

Where the S25 Ultra pulls ahead is in a handful of features that matter to specific but common use cases. It supports cross-site tracking blocking, Wi-Fi password sharing, focus modes, and app offloading — none of which are available on the Lava Shark 4G. Focus modes allow users to filter notifications and limit distractions by context, which is a meaningful productivity and wellbeing tool. App offloading frees up storage by removing unused apps while preserving their data. The ability to use the phone as a PC — via desktop mode when connected to a display — is also exclusive to the S25 Ultra, adding a versatility dimension the Lava Shark 4G lacks entirely.

This is a closer category than most others in this comparison, given how much common ground the two phones share at the OS level. Still, the Samsung Galaxy S25 Ultra holds a clear edge: its newer Android version combined with the exclusive features — particularly desktop PC mode and focus modes — give it a more complete and forward-looking software experience.

Battery:
battery power 5000 mAh 5000 mAh
has wireless charging
Supports fast charging
charging speed 18W 45W
comes with a charger
has a removable battery
has a battery level indicator
has a rechargeable battery

On paper, battery capacity is a dead heat — both phones carry a 5000 mAh cell. Raw capacity, however, only tells part of the story. The S25 Ultra's significantly more powerful processor and larger, higher-resolution display create greater power demands, while the Lava Shark 4G's modest hardware draws considerably less. Based purely on the provided specs, capacity alone is not sufficient to predict real-world endurance differences between the two.

Charging is where the two diverge. The S25 Ultra supports 45W fast charging — more than double the Lava Shark 4G's 18W — meaning a full charge will take substantially less time on the S25 Ultra, a practical advantage for users who charge on the go or during short windows. The S25 Ultra also supports wireless charging, adding a convenient cable-free option the Lava Shark 4G does not offer. One notable trade-off: the Lava Shark 4G comes with a charger in the box, while the S25 Ultra does not — meaning S25 Ultra buyers may need to purchase a compatible fast charger separately to take full advantage of the 45W speed.

Overall, the Samsung Galaxy S25 Ultra holds the edge in this category. The shared 5000 mAh capacity makes it a tie on paper, but the S25 Ultra's faster wired charging and added wireless charging flexibility give it meaningfully more versatile replenishment options — offset only slightly by the absence of an in-box charger.

Audio:
has a socket for a 3.5 mm audio jack
has stereo speakers
has aptX
has LDAC
has aptX HD
has aptX Adaptive
has aptX Lossless
Has a radio

Audio is a category where both phones make deliberate trade-offs that point to different user priorities. The Lava Shark 4G retains a 3.5 mm headphone jack, which remains a practical convenience for users with wired headphones or earphones — no adapter needed. It also includes a built-in FM radio, a feature that has largely disappeared from flagship devices and still holds value in areas with reliable broadcast coverage. The S25 Ultra drops both, offering neither a headphone jack nor a radio.

What the S25 Ultra gains in return is more compelling for most modern listening scenarios. It features stereo speakers — delivering a wider, more immersive soundstage for media playback compared to the Lava Shark 4G's single mono speaker. For wireless audio, the S25 Ultra supports both aptX and aptX HD alongside LDAC, the latter being Sony's high-resolution Bluetooth codec capable of transmitting up to 990 kbps — nearly three times the bandwidth of standard Bluetooth audio. This makes a meaningful difference when pairing with compatible high-quality wireless headphones, preserving significantly more audio detail than a standard Bluetooth connection.

The right choice here depends on usage habits. Users who rely on wired audio or value FM radio will find the Lava Shark 4G's retention of the headphone jack a genuine advantage. For everyone else — particularly those invested in wireless listening — the S25 Ultra's stereo speakers and high-fidelity Bluetooth codec support give it a clear overall edge in audio capability.

Wireless connectivity is another area of decisive separation. The Lava Shark 4G tops out at Wi-Fi 5 and 4G LTE with a peak download speed of 300 Mbits/s, while the S25 Ultra supports 5G, Wi-Fi 7, and theoretical download speeds up to 10,000 Mbits/s. Wi-Fi 7 brings lower latency and significantly higher throughput in congested environments — a tangible benefit in offices, airports, or dense urban areas. The S25 Ultra's Bluetooth 5.4 also edges ahead of the Lava Shark 4G's Bluetooth 5.0, offering improved connection stability and efficiency with modern peripherals. Additionally, the S25 Ultra supports NFC for contactless payments and device pairing, and adds eSIM support alongside its physical dual-SIM tray — the Lava Shark 4G offers neither.

The sensor and feature set tells a similar story. The S25 Ultra includes a gyroscope, compass, barometer, and ANT+ support — covering navigation precision, fitness tracking, and atmospheric sensing that the Lava Shark 4G entirely lacks. A stylus is also included with the S25 Ultra, adding a handwriting and annotation capability with no equivalent on the Lava Shark 4G. The one tangible advantage the Lava Shark 4G holds is its external memory card slot, which allows affordable storage expansion — the S25 Ultra has no such option, though its base 1TB internal storage largely offsets that limitation for most users.

The Samsung Galaxy S25 Ultra wins this category comprehensively. Faster cellular and Wi-Fi standards, a broader sensor array, NFC, eSIM, ANT+, and an included stylus collectively represent a far more capable and future-ready connectivity and features package. The Lava Shark 4G's microSD slot is a genuine practical plus, but it cannot offset the depth of what the S25 Ultra brings to this category.

Miscellaneous:
has a video light
Has sapphire glass display
Has a curved display
Has an e-paper display

Across every spec in this group, the Lava Shark 4G and the Samsung Galaxy S25 Ultra are identical. Both have a video light, neither uses sapphire glass, neither has a curved or e-paper display. There is nothing in this data set that distinguishes one from the other.

This is a complete tie based strictly on the provided specifications. Neither phone holds any advantage in this category.

Comparison Summary & Verdict

After a thorough comparison, the Lava Shark 4G and the Samsung Galaxy S25 Ultra clearly serve very different audiences. The Lava Shark 4G holds its own for budget-conscious users who value practical touches like a 3.5 mm headphone jack, a built-in FM radio, an external memory slot, and a bundled charger in the box. On the other side, the Samsung Galaxy S25 Ultra dominates in virtually every performance and feature category, from its Snapdragon 8 Elite chipset and stunning 498 ppi OLED display to its versatile quad-camera system with 5x optical zoom, 45W fast charging with wireless charging support, and a comprehensive connectivity suite including 5G and Wi-Fi 7.
