Both phones lead with a 50 MP primary sensor, but the similarities diverge quickly. The Moto G86 pairs its main camera with an additional 8 MP secondary lens, giving it more compositional flexibility, while the Realme 15x operates with a single rear camera. More critically, the G86 includes optical image stabilization (OIS) — a hardware mechanism that physically compensates for hand movement during shots and video recording. The Realme lacks OIS entirely, which means it will produce more motion blur in low light and shakier footage in handheld video scenarios. This is one of the most impactful real-world camera differences between the two devices.
Video capability is another area where the gap is unambiguous. The G86 records at up to 2160p (4K) at 30 fps, while the Realme 15x caps out at 1080p at 30 fps. For anyone who shoots video intended for large screens, editing, or archiving at high quality, this is a meaningful limitation on the Realme's part. Selfie shooters, however, may lean the other way: the Realme 15x packs a 50 MP front camera versus the G86's 32 MP, and the Realme's front aperture of f/2.4 is slightly narrower than the G86's f/2.2, meaning the G86 technically admits more light for selfies — partially offsetting the megapixel gap in dim conditions. The Realme also has a dual-tone LED flash on the rear for more natural-looking artificial lighting, a minor but practical advantage for flash photography.
Shared features across both phones are extensive — phase-detection autofocus, slow-motion video, HDR mode, manual exposure and ISO controls, panorama, and timelapse are all present on each device, so neither holds an advantage on camera versatility. Weighing everything, the Moto G86 holds the stronger overall camera package: OIS and 4K video are hardware advantages the Realme simply cannot replicate in software, and those matter far more across everyday photography and video use than the Realme's selfie megapixel lead.
