Installed it as soon as it was released ..
Initially it was jittery and laggy when updated to android 15 .
After 15 minutes phone is smoother than android 14 and animations and app opening speed has drastically improved
No battery drainage issue.
All things are present in beta 1 except gallery, widget sharing, and charging animation.
Also boot animation is similar to what is was in android 14
Call quality and network reception is good .
Only issue i face is no media control on lock screen may be it is a bug but i have checked and enabled all settings.
Dotted font is removed almost every where which in my opinion should be added as a option to choose between.
Settings page design has been changed but tiles should be smooth looking it looks unfinished.
