Performance Upgrades: Faster, Smoother Experience
Under the hood, FunTouch OS 15 is all about speed and fluidity. Thanks to a new Priority Scheduling model, apps launch up to 20% faster, even when your device is under heavy load. An advanced RAM compression technique boosts memory efficiency by about 40%, so switching between apps feels instant.

Gamers and power users will especially appreciate the stability during demanding sessions.
Smarter with AI: Enhanced Tools and Camera Features
FunTouch OS 15 brings AI out of the lab and into your hands. The built-in AI Image Lab can automatically enhance photos, remove unwanted shadows, and even organize your images into “Memories” albums.
Standout AI features:
- AI Photo Enhance: Fixes lighting, colors, and clarity in one tap.
- Shadow Removal: Makes scanned documents cleaner and more professional.
- Super Documents: Instantly scans, crops, and straightens papers for easy sharing.
These smart tools take the guesswork out of photo edits and daily tasks, so you save time and avoid frustration.
New Life for Gamers and Multitaskers
