Do you hate pop-ups like google assistant as much as I do?
I doubt it, but because I am willing to give you the benefit of the doubt, you get also get the following instructions for turning off the google assist garbage on your phone.
Steps to turn off:
0. Consider pruchasing one of these phones https://e.foundation/, and let me know if that works out for you. I am seriously considering it also. Google is getting too big for their britches.
1. Pull down twice from the top of your phone, you should see this gear icon for the "settings" and click the gear icon
2. Type "assistant" into the search settings bar at the top and click enter, then look for "Assistant Settings" in the list of results, and click it.
3. You will get a looong list of options, scroll down to find the "General" option and click it.
4. You should see a screen like this where you can turn off the google assistant. Make sure it is grey like it is in this picture.
You are welcome. And again, please let me know if you E phone works out instead of this fix, I would really like to know.
