Display and Design
The official specification lists a 17.20cm (6.77-inch) AMOLED display with 2392 × 1080 resolution and a refresh rate of up to 120Hz. App support and settings can affect the active refresh rate. The Nebula Purple version is listed at approximately 0.749cm thick, while actual measurements can vary slightly due to production and measurement methods.
The display uses an in-display optical fingerprint sensor. Buyers who prefer flat screens should examine the product photographs and, if possible, handle a curved-screen phone before purchasing. A protective case and screen protector may affect edge gestures and the overall feel.
Performance and Storage
The vivo Y400 Pro 5G uses the MediaTek Dimensity 7300 platform with an eight-core CPU and 4nm process. The 256GB configuration uses UFS 3.1 storage, while RAM is listed as LPDDR4X. Actual usable memory and storage are lower because the operating system and pre-installed applications use part of the stated capacity.
Expandable storage is not supported, so assess your photo, video, app and offline-media requirements before selecting the phone. Extended RAM is software-based and is not the same as additional physical RAM.
Cameras
The rear system is specified as a 50MP main camera plus a 2MP secondary camera, with a 32MP front camera. Resolution alone does not guarantee image quality: lighting, processing, stabilisation, shooting mode and user technique all affect the result. Review full-resolution samples from reliable sources before deciding based mainly on photography.
Battery, Charging and Connectivity
The official listing gives a 5500mAh typical battery capacity and charging support up to 90W with compatible vivo equipment. Actual charging speed and battery endurance depend on temperature, network strength, screen settings, applications and usage. Do not charge the phone while it is wet.
Connectivity includes dual-band Wi-Fi, Bluetooth 5.4, USB 2.0, GPS, OTG and an infrared blaster. NFC and FM radio are listed as unsupported. Network availability and 5G performance depend on the operator, plan, location and infrastructure.
What to Check Before Ordering
- Confirm the listing says Nebula Purple, 8GB RAM and 256GB storage.
- Verify the model, seller, warranty coverage and included accessories.
- Check supported mobile bands against your network and location.
- Review the curved display, phone dimensions and case availability.
- Confirm the final price, delivery estimate and return or replacement terms.
- Ignore an offer label unless it appears in the current checkout details.
