I'll be comparing the last Global beta 6.7.4.11G with this stable version.
I own a Meizu M3s 32G variant.

1. Camera - shutter button has been changed and no major improvements.

2. Battery - Drains much faster than the previous one, algorithm needs to be improved.

3. Heat - Phone heats a lot after minimal 4G internet usage.

4. Music - Nothing has been changed,still the same old withoit any enhancements.

5. Location - Slightly improved now.

6. Network Issues - Still network drops in remote areas while other phones have strong network in remote areas.

7. App compatibility - Still having compatibility issues with some apps. For eg. Greenify is having issues in hibernation which was not a problem in the last Beta.
