I have an Alcatel One Touch Idol 3 model 60451 running Android 6.0.1 and it updated a few days ago turning File Manager into adware that would reinstall itself no matter what I did. I tried everything I could find on the internet, including from Is this "Boost" / File Manager app a true system app or malware?.
I did as suggested and stopped auto-updates in Google Play. The only difference was that Google Play wasn't showing any apps when I clicked there. But I still was able to select no auto-updates in settings in Google Play. It hasn't reinstalled again for a while, but it's back. It's beginning to look like a factory reset is in order and then doesn't allow any more updates.
Finally, I did a full factory reset after stopping all updates on Google Play and the automatic restore on the phone and it not only appears again, it has another toolbar with it. Actually I did this 4 different times, all the while stopping everything that could be stopped. Finally, I closed down my Google account entirely and then did a factory reset. The result, it's back. File Manager comes with the phone but until an update last week it was unobtrusive.
I have never downloaded it deliberately or rooted my phone or downloaded an APK file or anything other than Google Play apps. I have been working on this for the past several days (obsession) and don't find any way to get rid of this.
Is it possible to delete Alcatel File Manager completely?
