Yesterday my mobile was just idle on the table whole day.
To my dismay in the evening I found that battery is almost empty and I got an SMS alert from the carrier that data plan is almost fully used. At the same time WIFI connection was available, but still phone used mobile data to transmit something (i don't know what).
I have a screenshot of the data usage, it's just a big peek. There is also information about data usage by apps. But none of them has several hundreds on MBs mentioned ;-( Is there any way to share this picture on this forum?
Any idea what could have gone wrong? How to find the culprit?
