Just wanted to add to this. I just was trying to update a new android phone, the essential. The update kept failing so I pulled up my firewall and Pi-Hole logs(DNS level ad-blocker), the phone kept trying to query "redirector.gvt1.com" on update. This was an android system update. This being a brand new phone, minutes out of the box, I took took to the web to look into it and arrived here after parsing through a bunch of misinformation, it seems. It is still unclear to me what or why it needs to contact this address, but it wasn't until I white-listed the address that I was able to perform the update. It's easy enough to see it was coming from the phones IP/Mac. It doesn't appear to me to be linked to any mal-ware. Just thought I would throw some more info into the information pool.
