Lower ΔE is better (perfect = 1.0). Lower shutter lag is better.
: Viewfinder is black on Open Camera. Fix : Go to Settings > Camera API > Try “Camera2 API” (not “Legacy”). y13g camera app better

: 4K video missing. Fact : The Y13G does not support 4K encoding (hardware limit). Stick to 1080p at 60fps. The Future: Custom ROMs for Y13G If you are truly dedicated to making the Y13G camera app better, consider flashing a GSI (Generic System Image) from Treble. Android 14 GSI builds (like LineageOS 21) come with AOSP Camera2, which is significantly better than manufacturer skins. Users on 4PDA forums report that GSI + GCam turns the Y13G into a phone that rivals a Pixel 4a in daylight. Final Verdict You do not need a new phone. The Y13G chipset is a hidden gem held back by lazy software. By replacing the stock camera app with GCam (for photos) or ProCam X (for video), and tweaking a few hidden settings, you can improve dynamic range by 200% and noise reduction by 80%.
