Typically, I get the system alert that says permissions have been removed from certain apps since I haven't used them. I'll review the list and delete what I don't use.

My phone every couple of months give me a list of apps that I haven't use jm a while and ask me to put them on 'invernation', if I see is something I have no plans to use anymore I just removed them, otherwise they getting inverned.

My home screen is essentially one page with 2 rows of folders. Each folder has a name (eg: Messaging, Games, Tools, etc). Apps I want to keep are inside those folders. The apps I'm testing, temporary apps, etc, are on my home screen (outside the folders), so I always know I have to deal with them (either remove them or keep them/move to a folder).

For the apps I already have, since I have to open the folders regularly, I can see what's there. If I see something I won't use anymore, I remove it. I might keep more than one app installed for the same purpose while testing, but eventually remove the ones I don't want.

To keep my device's storage clean, I use a normal file manager (Material Files on F-Droid).

So I don't really have the need for any cleaning app or Android feature. I also don't have "cleaning days" as I clean the phone as I use it or when I'm not doing anything.

This is probably something I should do. However realistically it only happens every few years when I change my phone or do a full reset

Typically whenever I notice an app I decide to delete or every time I do a fresh install, which is when I get a new phone or a new version of Android comes out

I don't have fixed schedule, I just occasionally check for any available updates for my apps and individually update each app. App that I think isn't worth it, I uninstall. Useless app that rarely updates will stay in my phone longer than the one that does.

I personally like SD Maid, which recently began a full refresh as SD Maid SE, for the actual cleanups (including random data for already-deleted apps). I keep it updated using Obtainium. It also has Shizuku support for us non-rooted folks!

I try to only install apps that I need. Of course my needs slowly change over time, and there bound to be some strugglers left behind.

I don't have a scheduled spring cleaning, but when I scroll down the app drawer and notice an app I no longer use, I'll go on a short cleaning spree.

Just today I replaced a faulty smart plug with a new one from another brand, so the corresponding app got the axe too.

I'm lazy and rarely do

Probably not as often as I should. 😂

I use the JINA Drawer App Organizer app (https://play.google.com/store/apps/details?id=com.mobeedom.android.jinaFS) and sort on Less Used apps to identify potential apps for removal.
