Details: Samsung Galaxy On Max
Carrier Network: Airtel
Reboot helps device to get normal but then i checked that message and it is that " You have used 90% data of daily limit."
I frequently use around 1GB a day but today i didn't use my device so checked for 'data usage' of today under settings but there is no option or info.
It is showing only for month usage.
What causes my device to react abnormally ?
How can i check for where data was consumed ?
How can i set notification if any app uses a chunk of background data ?
What is that '????' Next to tunnelbear ?
I know that's a lot of questions but this is very weird behaviour of the device.
