Thanks for sharing your experience! I also own a T95Z Plus (S912) and agree that it runs great for most tasks. The S912 chip handles 4K streaming and light gaming really well, especially with optimized firmware. Have you tried any custom ROMs like ATVxperience or LibreELEC to improve performance further?
A few tips that helped me:
Cooling: Adding small heatsinks or a fan prevents throttling.
Debloating: Removing unused apps with ADB or Debloater Tool speeds it up.
Launcher: Switching to Wolf Launcher or ATV Launcher reduces lag.
Would love to hear if you’ve found other tweaks!
