Hi dorimanx, as always thanks for all the time spent with this monster kernel that went growing and growing always more.
I would like to share my personal experience with latest two kernel versions (8.9 and 9.0).
My thoughts about 8.9 are impressively superb. Didn't have issues at all with a totally stable rock device in every conditions. The most smoothest, stable and battery balanced kernel version in my opinion.
With 9.0 unfortunately can't say the same expect objectively lower temperatures and more battery friendly.
The device it's smooth, really smooth but not like 8.9. No lag at all and fast as always.
It's stable? Here it goes my attention. I had only one reboot, but sometimes during the day (it happened like 6 times today) the device seems to hang for 1/2/3 seconds and resume after then without doing intensive task in really simple task like writing, scroll here and there.
Example: In 8.9 I could do everything meanwhile Google play store installs a app and with 9.0 it's not that easy.
In 8.9 listen to music and reading the newspaper app goes all smooth like butter and with 9.0 the experience it's not the same.
Don't get me wrong, don't want complain, just report my personal experience and I think that 9.0 promise really good but needs some improvements, but at the moment it doesn't have that "magic" that 8.9 has.
8.9 it's Magic, like WOW!! It's like a Ferrari
9.0 at the moment it's a wow candidate it's like a Porsche
BTW the temperature it's really lower with 9.
Performance profile without overclock.
