My G5 has been hacked without question

[Android Central Question]

My WiFi and data connection abysmally slow, less than 1 MBPS.

When I am messaging I see the blue streaks from swipe typing and spaces and incorrect characters are added.

My ringer is constantly off. My battery life is less than 3hours.

My camera focus gets messed with so I have to use manual focus.

Etc., Etc, . .. !!!???

Have factory reset a dozen times. Helps at first but the issues all reaappear quickly.

I don't connect to my network or use home WiFi and haven't for months.

Data connection only.

Anti virus, Avast, Sophos etc don't find anything.
I think reinstalling apps with preferences saved, and using the same Gmail account in setup after factory reset may be part of the problem..

I have heard that malware can be saved as, or in system folders which factory reset does not fix.

Does anyone have any advice or information relating to this?

I have basically given up the notion that this device will ever be "normal."
