Knuckle sense do function in HAM7 Lollipop. For the fingerprint sensor, it's only for taking pictures, videos and answering phone call.
Dual Windows - working good (limited only on apps that support dual windows. You can't open your downloaded apps or games)
One-hand UI - Working Good
Music Player DTS - only works when earphone/3.5mm jack is plugged in
WiFi - Improved
After install of this new firmware, you must do factory reset to remove the lag.
The update didn't erase my account, e-mail, settings, my apps, etc.
Overall is good to upgrade.
I'm from Philippines and I was on TL10 V100R001C00B120SP04 and you can directly upgrade to B324.
Enjoy your new Android Lollipop OS. Next is Android Marshmallow
