Security patches need a lot of testing yes.
From my understanding , they can also break certain features and cause bugs on existing implementation, meaning they would need to be rewritten to work for the security update and generally that is what takes the most time.
jfgt7j8qgxNowhere did I say just because it takes time that others cant do it faster than Asus has.
That's bull fart!
Samsung can release security update before Google did it.
Their One UI is even more customized than zenfone 8.
And now you told me it takes "time" to test it ?
I think both of us know why cause security update delay.
