I have around 50 trichrome library folders in /data/app using around 3 gb. What varies is the alphanumeric string after the package name denoting version: com.google.android.trichromelibrary_410408383-VgzblS0EY8swXcjTqN6reQ== Can I delete all but most recent to clean my system and regain some space? Or is it like WinSxS folder in Windows where all revisions of the same dll are stored for different programs to use? ###UPDATE AUGUST 2022### Latest Trichrome updates (I'm now on 511.209.733) seem to take care of old versions disinstalling them and leaving only the latest, no more need to manually delete in /data/app and /data/data

As I understand com.google.android.trichromelibrary is supposed to be a webview replacement in android 10+

I manged to remove 2 of them using pm uninstall so as to keep just 1 - but I get the below error, after being stuck with 2 instances remaining instead of 1. pm uninstall com.google.android.trichromelibrary_484407333 -- Why 4 instances of the same app. Is it by design ? How do I know which app tried to install the additional instance of trichrome library and why did it do so when 1 exists
-- This happened in the past too. How do I ***prevent recurrence.*** So I dont have to clean up everytime.
-- Other than brute rm -rf on the un-wanted folder anyway I can uninstall the unwanted instance
