Samsung Galaxy smartphones — particularly the S25 Ultra and S24 Ultra series — are among the most capable Android camera phones for gorilla trekking in Uganda in 2027. The Galaxy S25 Ultra’s 200MP main sensor, dedicated periscope telephoto cameras, and advanced computational photography stack give Android users tools that match or in some respects exceed competing iPhones for wildlife photography at range. The combination of multiple optical zoom levels, Samsung’s Expert RAW professional controls, and strong stabilisation technology makes these phones a serious gorilla photography option for the visitor who does not carry a dedicated camera system. This guide covers the specific settings, techniques, and practical preparation that extract the best gorilla photography results from Samsung Galaxy phones in Bwindi Forest’s demanding environment.
Galaxy S25 Ultra zoom capabilities explained
The S25 Ultra’s multi-lens system includes a 200MP main sensor with a 24mm equivalent field of view, a 50MP wide camera, a 50MP 5x optical zoom telephoto, and a 10MP 10x optical zoom periscope telephoto. This four-camera array, combined with Samsung’s Space Zoom computational processing, provides genuine optical zoom capability at the focal lengths most useful for gorilla photography at the 7-metre minimum approach distance. At 5x and 10x optical zoom, image quality is excellent in good to moderate light. Beyond 10x, the image is increasingly software-interpolated, but Samsung’s AI-based sharpening produces surprisingly usable results up to 30x in adequate conditions — though the critical observer can see interpolation artefacts at very high zoom levels, particularly in print-sized reproduction.
For gorilla photography in practice, use the 5x or 10x optical zoom setting as your primary focal length rather than attempting the dramatic 30-50x zoom levels Samsung’s marketing emphasises. At the regulated 7-metre minimum distance from gorillas, a 10x zoom provides equivalent focal length to approximately 250mm on a full-frame camera — comfortable for portraits that fill the frame with a gorilla’s face and upper body. Save the digital zoom extension for individual gorillas that have moved to greater distances and cannot be approached more closely within the group’s movement pattern.
Expert RAW: Samsung’s professional photography app
Samsung’s Expert RAW app — available from the Galaxy Store and pre-installed on some models — provides full manual camera controls and 16-bit RAW file capture on Galaxy phones. This is the most important single tool for serious gorilla photography on a Samsung device. Expert RAW’s manual controls allow you to set a minimum shutter speed (critical in low light to avoid motion blur from gorilla movement), set an ISO ceiling (to limit noise), and control exposure compensation in the same workflow used on dedicated mirrorless cameras.
RAW files captured through Expert RAW have significantly more post-processing latitude than Samsung’s standard JPEG output — particularly for recovering shadow detail in dark gorilla fur and managing the extreme contrast between the dark gorilla subject and a brighter forest background or open sky. The files are large but the quality advantage in the challenging lighting of Bwindi’s forest interior is substantial. Download Expert RAW before you travel to Uganda and practice with it — the manual controls have a learning curve that is worth conquering before you are standing in front of a silverback gorilla with one hour of permit time running.
Pro mode settings for gorilla encounters
Use these starting settings in Expert RAW or Samsung’s native Pro mode for gorilla photography in Bwindi’s forest: ISO — Auto with maximum ceiling set to 3200 (beyond this the noise in Samsung’s smaller-format sensors becomes difficult to manage in post-processing). Shutter speed — 1/400s minimum for stationary gorillas; 1/640s or faster for active subjects including juveniles playing or a silverback in motion. White balance — Auto (the forest light shifts constantly as gorillas move between deep shade and dappled sunlight through the canopy; manual white balance cannot respond fast enough and introduces more colour error than Samsung’s multi-zone Auto). Metering mode — Centre-weighted or spot metering pointed at the gorilla’s face to prevent the brighter background from causing the subject to be rendered as an underexposed silhouette.
Stabilisation: your most important physical asset
Samsung Galaxy phones include optical image stabilisation in multiple lens modules and electronic stabilisation across the system. For video recording during the gorilla encounter, enable Super Steady mode to maximise stabilisation — this is especially valuable when the group is moving through vegetation or when you are breathing heavily after a demanding uphill section. Super Steady mode introduces a slight crop to allow the stabilisation algorithm room to correct movement, but the steadier footage it delivers is worth the minor reduction in field of view.
For still photography, physical stabilisation technique matters more than any electronic assistance. Hold the phone with both hands, brace your elbows against your chest, and use trees, large roots, or your guide’s offered arm as a physical rest point when gorillas are stationary. At telephoto zoom levels (10x and beyond) even small breathing movements are magnified in the frame and produce noticeably blurred captures. Exhale slowly before pressing the shutter and use the physical volume button rather than the on-screen shutter control for more stable capture initiation.
Director’s View and creative modes
Samsung’s Director’s View mode simultaneously records from multiple cameras — for example, the main wide camera and the telephoto zoom — displaying both perspectives on screen and combining them in the final video output. For documenting the full atmosphere of a gorilla encounter, this split-view capability creates a visual record that single-camera capture cannot match: the wide camera capturing the forest context and the presence of other group members while the telephoto provides close detail of the focal gorilla subject. The footage has an immediate, documentary quality that many viewers find more engaging than traditional single-perspective wildlife video.
Practical preparation for Android gorilla photographers
Fully charge the phone and bring a power bank rated at 10,000mAh or larger — a full day in Bwindi’s cool, humid conditions drains batteries faster than standard outdoor use and faster than Samsung’s published battery life figures suggest. Enable the phone’s Performance Mode in Settings → Battery to ensure the camera processor does not throttle speed at a critical moment to preserve battery. Clean all camera lenses on the phone thoroughly before entering the forest. In Bwindi’s perpetually damp environment, moisture and condensation can coat the glass camera surfaces with a fine film that reduces sharpness significantly — a brief wipe with a microfibre cloth at the trailhead takes ten seconds and can be the difference between crisp gorilla portraits and soft, hazy captures.
Storage management: Samsung’s Expert RAW captures 16-bit raw files that can exceed 50MB each. If shooting burst sequences during the encounter, storage consumption is rapid. A 256GB or 512GB Galaxy model is strongly recommended, and deleting obvious failures during the return trek preserves space for subsequent days. With careful preparation and the right settings, a Samsung Galaxy S25 Ultra delivers gorilla photography results that compete genuinely with entry-level and mid-range dedicated camera systems — the key is treating the device as a serious photographic tool that requires deliberate configuration rather than simply pointing and shooting.
