I have a Pixel 4 XL and today I noticed that every so often when I unlock my phone it will open to some scammy chrome tab. I use Firefox most of the time so I don’t know where this malware came from. I’ve tried deleting history/cookies and it hasn’t worked. I can’t delete chrome because you can’t do that on Pixel devices. Anybody have any advice other than doing a factory reset?
You have got some interesting replies, so instead of repeating what the others say, I will give you the advice of installing GrapheneOS and degoogle.
