I am getting some wired behaviour from my new sony xpera XZ2 with android 9 update. Mostely i connected with WIFI but when i turn it off and try to enable mobile data sometime it works and sometime mobile data icon show that it turn on(change to blue color) but actually it not show any mobile data signlas (up and down arrows near to mobile signals) and no intenet work until i restart my phone and then then mobile data work fine.
I have factory reset my mobile but still no change. Is there any settings in mobile to make it work always?
