Hi Joao
No, you don't need to root. Just run it using adb via USB.
I like the phone very much. Its a great piece of hardware. The only thing I really miss is having a custom ROM for it.. Otherwise, I'm pretty happy.
I've posted the link to this script on XDA forums. Probably you can get some help there.

Thanks @joaofl, I ended up doing that once I found the link.

It has worked nicely so far.

@joaofl is there a way people can contribute to this to find more crap to add to the list? Also did you notice a difference in battery time?

@thetup
I believe you can make pull requests. If not, please suggest changes here on the comments.

I can't really tell if there was any increase in battery life, as I did the cleanup on the first hours after I got the phone. But it usually lasts 2,5 days..

I wish there was a lineage distribution for it, as it is a nice phone. Because there is none, we have to clean the mess by Samsung

@joaofl thank you for this list! I found a little typo:
package:com.microsoft.skydrive should be com.microsoft.skydrive

@W-sch
Well spotted. Correcting it now

Will removing those Knox apps trigger Knox? Thank you for your work.

I'm also enjoying the A40 but the whole Knox thing is annoying, not that I ever used or need them since I've always used LineageOS with microg.

@3nly In my opinion, Knox is only one of the annoying bloatwares.
It's ok to remove them. In the end you are not removing from the image, but from the installation. If you restore you phone they will be there again.

Have you found anything about lineage for the a40?

@joaofl I ended up removing the Knox apps without any issue, but I might actually use Secure Folder if no LineageOS becomes available.

Haven't found anything "official" yet, most roms for the A40 at the moment are just GSI. We'll have to wait I guess.

Powershell version
adb shell 'pm list packages' | %{ $_ -replace "package:","adb uninstall --user 0 "} |Sort-Object

Hi ! Thanks a lot for this.
Have you tried to remove the Gapps either ? I've seen you removed "google stuff" but i guess it's not THE Gapps?
I can't wait for a Lineage distribution but it seems that it's not that simple with the chip...

@nayessiva
No, It does not remove Gapps. That would be a major step, which would break many core functionalities if there is no replacement.

I cant see any development on the lineage port to it, unfortunately. From discussions I had, it does not seem to be because of the chip, but mostly lack of interest from Samsung users.
Really wish it was different.

@4lex11s
Thanks for the addition. Will add it as a comment on the code

I cant see any development on the lineage port to it, unfortunately. From discussions I had, it does not seem to be because of the chip, but mostly lack of interest from Samsung users.

I guess it's probably because there is now so many different devices from samsung... hard to maintain it all.
