Just signup the first free month with Netflix standard package, it works perfectly in both Q16, Q5 and H8 Octa Core. Please to be noted HD only available for standard package, basic package do not support HD.

Please to be noted, Netflix will start the movies with SD at the beginning and slowly increase the resolution to HD, it is handle automatically by Netflix.

Subtitle available for English, French and Chinese, but I did not see any Malay subtitle yet.

Pls find below comment from my H8 Octa Core customer  :

No issue with connection and compatibility,  but the Netflix content is less then preinstalled free streaming  apps.

I personally tested H8 2+16 working smoothly with Netflix. I strongly believe you use the wrong APK which the seller you bought did not tell you. Uninstall the factory install Netflix and reinstall again from Google Play store.
