I have a securities concern. I installed a VPN software on my android and just after (the next day) android asks me do install an update (that is already downloaded via the VPN). I don't fully trust my VPN software and I can not trust that the downloaded update is legitimate. I would like to force Android to redownload this update but from OUTSIDE the VPN (so delete the downloaded file and let android redownload it). How to do that?
