i honestly do not face any issue of slowness after update to pie. what i learned before during the update of nougat to oreo is that once the update is completed, we have to wait for like around 10 mins before using it and not just after the phone has freshly logged in. this gives time for the phone to configure and adjust its file system.. etc.. at first i feel bad of the text color but after i changed the theme.. all is going well even batt consumption is way better as per my experience.
