Editorial report

vivo Y400 4G technical sheet

The vivo Y400 4G suits buyers who want a bright display, protection from water and dust, and a large battery. Its main trade-off is the camera: the main sensor is small and has no optical stabilization.

The 6.7-inch AMOLED display reaches 1,800 nits and runs at 120 Hz, putting the design and display ahead of most phones of its time. The 7.9 mm body adds IP68 and IP69 protection against water and dust, along with resistance to shocks and drops under MIL-STD-810H. Its 6,000 mAh battery supports 44 W fast charging and reverse charging.

The Snapdragon 685, 8 GB of RAM and 256 GB of storage make performance typical for its time. Android 15, Dual Nano-SIM and NFC cover useful basics, while connectivity is worse than most phones of the same period. The 50 MP main camera records 1080p at 30 fps, but its 1/2.96″ sensor is among the weakest and it has no optical zoom. Overall, the phone is typical for its time, with a NeoScore of 5.9. It is best suited to buyers who prioritize the screen, protection and battery over photography.
