I am running Android 4.3 on a Samsung Galaxy S3, switching on or off WiFi on a need-to-use basis. A few days back, I realized that WiFi would spontaneously be switched on. I switched it off, but it would be switched on again.
I probably have downloaded an app or an update that is the reason for that behaviour. After trying to uninstall a number of these apps (no result up to now), I am wondering whether there is a possibility to log which app does what on the wifi connection, so as to identify the culprit.
I tried WIFi Fixer and saw a log line (among many others) that said:
Failover set to: www.baidu.com
This makes me thinks the culprit tries to go to baidu (I have never connected to baidu). Avast scan does not detect a virus, so I am stuck.
