Samsung S8 Data always on even when connected to WIFI.

Hi.

Any suggestions, I've tried everything. When i optimise the phone 4G turns off but it just comes back on. Wifi is connected at the same time.

I've went through programs and stopped mobile background data. I've deleted programs I never use. Restarted the phone.

Any suggestions?

Solved it was the Amazon Alexa app for some reason.

Welcome to Android Central! I'm glad you found the problem. Just curious, how did you know the phone was actually using mobile data while connected to wi-fi -- did you see the mobile data usage going up?

Thanks. Yes 4G signal comes on when I open the Alexa app and stays on even when it shows I'm on Wifi.

I don't know how to fix apart from install the app.
