• First Y-series with AMOLED + screen fingerprint – 6.38-inch Super AMOLED panel with 404 ppi and 105% NTSC color gamut; optical in-display fingerprint sensor offers fast, secure unlocking 
• Versatile triple camera system – 120° ultra-wide lens for landscapes and group shots; Super HDR for backlit scenes; super night mode for low-light photography; 16MP front camera with AI beautification and 103 facial feature point recognition 
• Jovi AI assistant with dedicated button – Physical AI button on left side for quick voice commands, smart scene recognition, and multi-turn dialogue for tasks like ordering food or booking tickets 
• Multi-Turbo gaming optimization – System Turbo + Game Turbo with Game Mode, frame stabilization, and network optimization for smoother gaming performance; supports frame rate testing and optimization 
• 2.5D glass design with prismatic finish – Nano-scale ion plating creates rainbow-like reflections under sunlight; 8.13mm slim profile at 179g, comfortable grip 
• Aging chipset by 2026 standards – Helio P65 is a 2019 mid-range chip; handles basic tasks and light gaming but struggles with demanding apps; 12nm process is efficient but outdated 
• Limited software updates – Launched with Android 9 Pie; no further major OS updates expected; security patches no longer provided, posing risks for daily use
