Yeah stagefright fixed but don't see anything else different either. The bug with expanding notifications auto-minimising is still there. I got this from a taiwanese thread
about this firmware:
Update "Home" version.
Optimization "cameras" startup speed.
Re-optimized phone heating problem.
Upgrading contacts database.
Optimization of fluency.
"Camera" photographs accelerated storage time!
Optimization "cameras" code.
"Fingerprint" to enhance the ability to identify.
"Calendar" interface optimization.
Add "VoLET" function.
I don't notice any difference to camera startup time (from cold boot). WIll take some time to see if it's better in general.
